Why Does My Drinking Water Taste Metallic?

Why Does My Drinking Water Taste Metallic?

Metallic taste in water is commonly caused by iron, manganese, zinc, copper or low pH. A simple water test identifies the specific parameter, and multi-stage filtration resolves it. The Five Most Common Causes Cause Typical Level Causing Taste Source Iron (Fe²⁺ dissolved) Above 0.1 mg/L Borehole geology, old iron pipes Manganese Above 0.05 mg/L Borehole geology, anaerobic conditions Zinc Above 3–5 mg/L Galvanised pipes, aged galvanised tanks Copper Above 1 mg/L New copper pipes, corrosive (low-pH) water Low pH (acidic water) Below pH 6.5 Rainwater collection, soft groundwater, distilled water Diagnosing the Cause The most reliable approach is a basic water chemistry test covering iron, manganese, zinc, copper and pH, available from any KENAS-accredited laboratory for approximately KSh 3,000–5,000. A simpler at-home approach is a TDS meter combined with pH strips, which can confirm whether pH or high mineral content is the driver, though these don't identify specific metals. Source: Metallic taste in water, causes and solutions, SpringWell Water. Iron and Manganese: Kenya's Most Common Metallic Taste Culprits Kenya's Rift Valley geology and many highland areas have naturally elevated iron and manganese in groundwater. These minerals are not harmful at moderate levels, but they cause a pronounced metallic or bitter taste at levels above taste thresholds and cause red/brown staining in sinks, toilets and laundry above 0.3 mg/L (iron) and 0.1 mg/L (manganese). Iron and manganese in groundwater exist in two forms: dissolved (ferrous/manganous) and particulate (ferric/manganic). Dissolved forms require oxidation to convert them to particulate form before filtration. Some multi-stage systems include an oxidising pre-treatment stage for this purpose. pH and Its Effect on Taste Pure water has a pH of 7.0 (neutral). Slightly acidic water (pH 6.0–6.8) has a noticeably sharp or metallic taste even in the absence of elevated metal ions. Rainwater collection systems and some highland boreholes produce naturally acidic water. The iClear Standard purifier includes a mineralisation or alkaline filter as a final stage that raises pH to a comfortable 7.0–7.5, improving taste significantly. Addressing the Problem For iron/manganese from a borehole: an oxidising pre-filter followed by RO removes dissolved metals effectively. For galvanised tanks and pipes: replacing zinc-coated steel with food-grade PE tanks and CPVC plumbing eliminates zinc leaching. For copper from new pipes: flush the system daily for the first 4–6 weeks after installation; copper levels normalise as the pipe surface oxidises. For low pH: an alkaline/mineralisation stage at the output of your RO system restores a comfortable, neutral pH. Q: Can metallic-tasting water be harmful? A: At the levels typically producing taste changes in Kenyan water, metals are aesthetically unpleasant rather than acutely dangerous. However, at higher concentrations, manganese has been linked to neurological effects and iron to oxidative stress. Testing establishes whether levels exceed health guidelines. Q: My water tasted fine for years from my borehole, why has it changed? A: Seasonal water table changes and shifts in nearby land use can alter the chemical profile of borehole water. A change in taste is a reason to retest. Get your metallic taste diagnosed and fixed iClear assesses your water chemistry and configures the right filtration to restore clean, neutral taste.

New Building? Here's Why You Should Test Your Water for Lead and Copper First

New Building? Here's Why You Should Test Your Water for Lead and Copper First

In newly constructed buildings, solder used to join copper pipes can leach lead into the first several litres of water after periods of stagnation. Flushing taps and using RO filtration protects against this risk. The Source: Pipe Joints and Fittings In Kenya, copper and CPVC piping are common in residential and commercial construction. While copper piping itself is relatively inert, the traditional solder used to join copper pipes historically contained lead at concentrations of 40% to 50%. Although lead-free solders (containing tin and silver) are now specified in new construction, compliance is not universal, and buildings constructed before 2010 are particularly likely to contain leaded solder joints. Additionally, brass fittings, taps, valves and connectors, can contain up to 8% lead by mass under older KEBS standards. Newer NSF/ANSI 61-compliant fittings are restricted to 0.25% lead. Plumber installing copper pipes. How Lead Enters Your Drinking Water Lead does not dissolve continuously from pipe joints into flowing water. The problem is stagnation. When water sits in contact with leaded solder or brass fittings overnight, the slightly acidic water dissolves trace amounts of lead from the metal surface. The longer the stagnation period, the higher the lead concentration in the first litres drawn from the tap. Health Effects of Lead in Drinking Water The WHO states that there is no safe level of lead exposure. At low chronic exposure levels, lead accumulates in bone, kidney and brain tissue. Children under five and pregnant women are most vulnerable, even low blood lead levels impair cognitive development and reduce IQ. Lead exposure has no visible symptoms at the levels typical in drinking water. The Flushing Rule, and Its Limits Occupational health guidance recommends flushing the cold tap for 30–60 seconds before drawing water for drinking or cooking in buildings with suspected leaded plumbing. This clears the standing water in the immediate pipe run. However: Flushing does not help for systems with elevated lead in the main building riser or service connection. It requires consistent behavioural change, easily forgotten during high-demand periods. It wastes significant water in the context of Nairobi's rationed supply. A More Reliable Approach RO membranes reject dissolved lead at rates of 95–99%. A point-of-use RO system fitted to the kitchen tap provides reliable, automatic protection without requiring occupant behaviour change. Testing your water annually for lead and copper in a new building is also recommended to establish a baseline and monitor for changes. Q: Does copper in my water indicate a health problem? A: Copper at low levels (below 2 mg/L WHO guideline) has no adverse health effects and is actually an essential trace mineral. At higher levels, acute copper toxicity causes gastrointestinal distress. Newly installed copper pipes can contribute elevated copper in the first few months of use, which typically normalises. Protect your family from lead in plumbing iClear's RO systems remove up to 99% of dissolved lead from your drinking water. Find out more.

Is Your New Borehole Actually Safe to Drink From?

Is Your New Borehole Actually Safe to Drink From?

A newly drilled borehole must be flushed, disinfected and laboratory-tested before use as a drinking water source. Skipping these steps risks exposure to drilling fluid contaminants and geological minerals. What Happens During Drilling That Affects Water Quality Borehole drilling introduces several contamination risks that must be addressed before the water is safe to consume. Drilling equipment carries lubricants, hydraulic fluids and hydrocarbon residues. The drilling process can also mobilise geological materials, fluoride, arsenic, manganese and iron, that were previously bound in rock strata above the aquifer. Additionally, the drilling process disrupts the natural groundwater flow around the borehole, often temporarily drawing in shallower, less-protected water from surface layers. This typically clears within days but must be confirmed by testing. The Mandatory Commissioning Steps Kenya Water Resources Authority (WRA) and KEBS KS 459 specify the following steps before a borehole is approved for domestic use: Step Purpose Who Performs It Yield test (pumping test) Establish sustainable abstraction rate Licensed drilling contractor Development flushing Flush drilling contaminants from the aquifer Drilling contractor Borehole disinfection Shock-chlorinate to kill introduced bacteria Drilling contractor / water engineer Physical-chemical test Test TDS, pH, hardness, nitrate, fluoride, iron KENAS-accredited laboratory Bacteriological test Test for E. coli and coliforms KENAS-accredited laboratory WRA abstraction licence Legal authorisation to abstract Water Resources Authority Source: Kenya Water Resources Authority, Borehole Drilling Guidelines; KEWI Water Quality Lab Services. Common Findings in New Borehole Water High iron and manganese: causes orange/brown staining and metallic taste, aesthetically unpleasant and at high levels poses health concerns. Elevated fluoride: common in Rift Valley geology; above 1.5 mg/L causes dental fluorosis; above 4 mg/L risks skeletal fluorosis. High total hardness: not a health risk but causes scale buildup and interferes with soap and appliances. Elevated TDS: a marker for dissolved mineral load; requires further testing to identify specific parameters. Which Treatment Is Right for Your Borehole? The correct treatment system depends on your laboratory results. Reverse osmosis is highly effective for reducing fluoride, nitrates, heavy metals, and overall TDS. Where iron levels are very high, a pre-treatment iron removal unit is recommended before the RO membrane to extend membrane life. Q: My driller says the water looks clear so it must be safe, is that right? A: Clarity alone is not an indicator of safety. Fluoride, nitrates and many bacteria produce no visible change in water appearance. Laboratory testing is the only reliable method. Q: How long after drilling should I wait before using the borehole? A: At minimum 72 hours after shock chlorination and flushing. Testing results must confirm safety before regular use begins. Start your borehole right iClear assesses your laboratory results and recommends the right treatment solution for your specific water chemistry. Find out more.

Are Your Plastic Storage Containers Leaching into Your Water?

Are Your Plastic Storage Containers Leaching into Your Water?

Plastics numbered 1 (PET), 2 (HDPE) and 5 (PP) are considered food-safe for cold water storage. Plastics 3, 6 and 7 should be avoided, particularly at high temperatures. The Plastic Resin Code System The recycling symbols on the base of plastic containers, numbers 1 through 7, identify the type of resin used in manufacture. These codes matter for water safety because different resins have different chemical stability profiles and leach different compounds under different conditions. Resin Code Plastic Type Water Storage Safety 1, PET Polyethylene terephthalate Safe for single use; do not refill indefinitely 2, HDPE High-density polyethylene Safe; used in most water jerry cans 3, PVC Polyvinyl chloride Avoid; can leach chlorine compounds and lead 4, LDPE Low-density polyethylene Generally safe at room temperature 5, PP Polypropylene Safe; heat-resistant and stable 6, PS Polystyrene Avoid; leaches styrene, a suspected carcinogen 7, Other Mixed or polycarbonate Avoid PC (contains BPA); others vary The Temperature Factor Even food-safe plastics become more problematic at high temperatures. A PET bottle left in a vehicle in Nairobi's sun, where interior temperatures can exceed 60°C, can leach acetaldehyde, phthalates and antimony into the water it contains. Studies show that leaching rates increase exponentially with temperature: antimony concentrations in PET water bottles stored at 60°C for two weeks were 630 times higher than in bottles stored at 25°C. Source: Antimony and BPA leaching from PET bottles at elevated temperature, Green Matters. Reusing Plastic Water Bottles Single-use PET water bottles (resin code 1) are not designed to be refilled repeatedly. The surface develops microscratches that harbour bacteria, and repeated washing, especially with hot water or dishwasher cycles, accelerates chemical breakdown and leaching. Independent tests have found that repeatedly refilled PET bottles can contain bacteria counts exceeding those found in toilet water. Source: Bacterial contamination in reused single-use bottles, NKY Tribune. Safe Storage Recommendations Use food-grade HDPE (code 2) or PP (code 5) containers for household water storage. Store water containers out of direct sunlight and away from heat sources. Replace any container that is cracked, heavily scratched or discoloured. Never use containers that previously held non-food substances, traces of original contents can leach into stored water. Treat water before storage as well as at point of use for a double layer of protection. Q: Should I worry about the pipes in my house? A: PVC and CPVC pipes used in Kenyan plumbing are generally food-grade. The primary concern is older buildings that may have copper or lead solder joints, covered in a separate article on new plumbing. Store clean water in a safe system iClear's certified components ensure your water stays clean from the membrane to the tap. Find out more.

What Happens If You Don't Replace Your Water Filter?

What Happens If You Don't Replace Your Water Filter?

A clogged filter reduces flow rate and pressure, but a saturated carbon filter can release previously captured contaminants back into your water, a phenomenon known as - dumping. Replace on schedule, not just when pressure drops. The Three Failure Modes of an Ageing Filter Water filters don't simply stop working when they reach the end of their service life. Depending on the filter type, expiry manifests in three distinct and increasingly serious ways: 1. Reduced Flow and Pressure As a sediment pre-filter loads with particles, flow restriction increases. You may notice slower fill times, reduced pressure at the tap, or the RO storage tank taking longer to refill. This is the most visible sign of a spent filter and the one most homeowners act on. 2. Breakthrough, Contaminants Passing Through Unfiltered RO membranes have a finite capacity to reject dissolved solids. A membrane that has exceeded its service life shows declining rejection rates. A new membrane rejects >97% of total dissolved solids; a degraded one may only reject 80–85%, allowing fluoride, nitrates and heavy metals through at levels approaching the untreated source water. 3. Dumping, The Worst-Case Scenario Activated carbon filters work by adsorption: contaminants bind to the carbon surface. That surface area is finite. Once fully saturated, a carbon filter cannot adsorb any further contaminants, but temperature fluctuations, pH shifts or simply continued water flow can cause previously captured contaminants to desorb and re-enter the water stream. This means a severely overdue carbon filter can produce water with higher contamination than the unfiltered source. Recommended Replacement Schedule Component Typical Lifespan Primary Failure Mode if Overdue PP sediment pre-filter 3–6 months Restriction, bacterial growth in filter media Granular activated carbon 6–12 months Contaminant dumping Carbon block post-filter 6–12 months Taste degradation, chloramine breakthrough RO membrane 18–36 months TDS rejection decline, membrane fouling Mineralisation / alkaline filter 12 months Mineral depletion, acidic output Signs Your Filters Are Overdue Noticeable drop in flow rate or tap pressure. Return of chlorine taste or odour in filtered water. TDS reading at the tap approaching the level of your unfiltered source water. Visible discolouration in the first filter housing. Q: Can I just clean and reuse my RO membrane? A: RO membranes are not designed to be cleaned and reused by end users. Chemical cleaning by trained technicians can extend membrane life in some commercial contexts, but household membranes should be replaced on schedule. Q: How do I know what stage my system is at in its service life? A: The best practice is to log the installation date of each filter stage. A TDS meter measured before and after the membrane gives a real-time indication of membrane health between service dates. Never miss a filter replacement iClear's service schedule ensures every filter stage is replaced at the right time, every time. Find out more.

Water Trucks in Kenya: Is It Actually Safe to Drink?

Water Trucks in Kenya: Is It Actually Safe to Drink?

Independent testing of water trucks in Nairobi found coliform bacteria in over 60% of samples. Truck water should always be treated before drinking. Who Uses Water Trucks Water? A significant portion of households and businesses in Nairobi, Mombasa and other urban centres supplement, or entirely depend on, water delivered by tanker trucks, locally known as lorries. This is particularly true during water rationing, in peri-urban estates without piped connections and in informal settlements. AFIDEP estimates that approximately 3.9 million urban Kenyans use water purchased from vendors or trucks as their primary supply. What Testing Has Found Research published in the East African Medical Journal tested bowser water samples from 12 routes across Nairobi and found: Test Parameter WHO Limit % of Samples Exceeding Limit Total coliform bacteria 0 per 100 ml 63% E. coli 0 per 100 ml 41% Turbidity 1 NTU 28% Total dissolved solids 1,000 mg/L 19% Source: Microbiological quality of water sold by vendors in Nairobi, East African Medical Journal. Why Bowser Water Can Be Contaminated Tanker trucks often carry non-potable industrial water as well as drinking water, using the same compartments without adequate cleaning between loads. Tanks are rarely fully emptied between deliveries; residual water in the bottom supports bacterial growth. Flexible hoses used to fill household tanks are commonly stored on the ground, contaminating the fill line. Drivers may top up trucks from unregulated or partially treated sources during periods of high demand. Safe Storage Practices if You Use Bowser Water If bowser water is your primary source, these practices reduce contamination risk until a permanent solution is in place: Use a clean, covered storage tank, ideally with a tap, not an open scoop. Treat stored water with sodium hypochlorite (jik) at a rate of 1 ml per 10 litres, then allow 30 minutes contact time before use. Run all drinking and cooking water through a point-of-use RO purifier. Clean your storage tank quarterly, sediment accumulation at the base harbours pathogens. The Case for On-Site Purification A point-of-use RO purifier connected to your household tap treats water regardless of its source, whether municipal, borehole or bowser, so you have consistently safe drinking water even when your supply quality varies. The iClear Standard purifier is designed precisely for this scenario: it handles variable input quality and produces verified safe output at the tap. Q: Can I identify unsafe bowser water by colour or smell? A: Not reliably. Coliform bacteria and E. coli produce no visible colour or odour. Laboratory testing or on-site purification is the only reliable safeguard. Q: Is it legal to sell untreated bowser water in Nairobi? A: It is not. WASREB regulations require all commercial water vendors to supply treated water meeting Kenya Bureau of Standards KS EAS 12. Enforcement remains inconsistent. Treat any water source, reliably iClear purifies municipal, borehole and bowser water to KS EAS 12 standard at every pour. Find out more.

How Kenya's Flooding Season Contaminates Your Drinking Water

How Kenya's Flooding Season Contaminates Your Drinking Water

During the long rains, surface runoff carries agricultural chemicals, sewage and sediment into reservoirs and boreholes. Contamination peaks within 48 and 72 hours of heavy rainfall. Why Flooding is a Water Quality Emergency Kenya experiences two distinct rainy seasons, the long rains (March–May) and the short rains (October–December). Both bring intense downpours that routinely overwhelm municipal drainage systems and water treatment works. When flood water flows across farmland, settlements and industrial areas before reaching rivers and reservoirs, it carries a heavy load of contaminants. The 2023 El Niño floods caused at least 31 counties to report elevated turbidity in municipal water supplies, prompting WASREB to issue advisories for residents in Kisumu, Nakuru and parts of Nairobi to boil water before drinking. Source: WASREB Flood Advisory Update, November 2023. The Four Main Contaminants Introduced by Flooding Contaminant Source During Floods Health Risk E. coli / coliform bacteria Sewage overflow and animal waste Diarrhoeal disease, typhoid Nitrates Fertiliser runoff from farms Methemoglobinaemia in infants Turbidity / sediment Eroded soil and silt Harbours pathogens; reduces treatment efficacy Pesticide residues Agricultural land runoff Neurological and hormonal disruption (long-term) Are Boreholes Affected? A common misconception is that boreholes are protected from surface contamination. In reality, poorly sealed borehole casings allow flood water to short-circuit down the annular space between the casing and the borehole wall. Research conducted in Kiambu County showed that coliform counts in shallow boreholes increased by an average of 340% during the first week after heavy rainfall events. Source: Groundwater contamination during flood events, Kiambu County study. What Your Municipal Supplier Does, and Where the Gaps Are Nairobi Water and Sewerage Company and county utilities increase chlorine dosing during high-turbidity events. However, high sediment loads can bind with chlorine, reducing its effectiveness, and treatment plants can be overwhelmed during extreme events, leading to partially treated water reaching households. Turbidity above 4 NTU makes chlorination significantly less effective (WHO guideline: <1 NTU for treated water). Flooding can dislodge biofilm in distribution pipes, releasing bacteria into the supply. Pressure drops caused by burst mains allow back-siphonage of contaminated water. How to Protect Your Household During Rainy Season Continue running your RO purifier, it handles both biological and chemical contaminants. Replace sediment pre-filters promptly after a major flood event; they clog faster during high-turbidity periods. If you rely on a tank, cover it securely and avoid using it for the first 24 hours of a flood event to allow sediment to settle. If you experience a notable change in taste, colour or odour during rains, contact your purifier service provider to check your system. Q: Should I stop using my borehole during heavy rains? A: You should increase monitoring frequency. Have a water quality test done within 72 hours of any significant flood event on your property. Q: Will boiling alone make flood-contaminated water safe? A: Boiling kills most bacteria and viruses but does not remove nitrates, pesticides or sediment. RO filtration addresses biological and chemical contaminants together. Stay safe through every rainy season iClear's multi-stage purifiers handle surges in turbidity, bacteria and chemical load. Find out more.

Microplastics in Drinking Water: What Nairobi Households Need to Know

Microplastics in Drinking Water: What Nairobi Households Need to Know

Microplastics have been detected in tap water, borehole water and even bottled water worldwide, including in East Africa. Reverse osmosis filtration removes over 99% of microplastic particles. What Are Microplastics? Microplastics are plastic fragments smaller than 5 mm, many invisible to the naked eye. They originate from degraded plastic packaging, synthetic textiles, vehicle tyres and industrial discharge. Once in the water cycle they are extremely difficult to remove through conventional treatment alone. A 2018 study commissioned by Orb Media tested tap water from 14 countries and found plastic fibres in 83% of samples. A peer-reviewed analysis published in the journal Environmental Science & Technology estimated that adults consume between 39,000 and 52,000 microplastic particles every year through food and water alone. Source: Environmental Science & Technology, Microplastic Ingestion Estimates, American Chemical Society, 2019. How Microplastics Enter Kenya's Water Supply Nairobi and other urban centres draw water from reservoirs and rivers that receive runoff from densely populated areas. Plastic litter decomposes in sunlight and breaks into fragments that enter the water table. Agricultural plastic mulch and greenhouse covers add to the load during the rainy season. Borehole water is not immune, plastics enter aquifer recharge zones through soil percolation. Kenya generates an estimated 0.94 kg of solid waste per person per day, a significant fraction of which is plastic. Much of that waste is disposed of informally near waterways. Source: Kenya National Solid Waste Management Strategy, NEMA 2021. Health Concerns Linked to Microplastics Current research is still establishing long-term health thresholds for microplastics. However, scientists have identified several areas of concern: Microplastics can carry adsorbed chemical pollutants, pesticides, heavy metals and plasticisers, into the body. Lab studies show that nanoplastics (the smallest fraction) can cross cell membranes and accumulate in tissue. Some plastics contain endocrine-disrupting compounds such as bisphenol A (BPA) and phthalates. The World Health Organisation issued a preliminary risk assessment in 2019 calling for further research and improved water treatment standards. How Reverse Osmosis Removes Microplastics Reverse osmosis (RO) forces water through a semi-permeable membrane with pores of approximately 0.0001 microns, far smaller than any microplastic particle. Independent tests show RO systems remove more than 99% of microplastics, including nanoplastic fractions that pass through conventional filters. Filtration Method Approx. Pore Size Microplastic Removal Sediment filter 5–50 microns Partial (large particles only) Activated carbon ~1 micron Moderate Ultrafiltration 0.01–0.1 micron High Reverse osmosis ~0.0001 micron 99%+ All iClear purifiers use multi-stage RO membranes specifically sized to intercept microplastic particles at every stage of the filtration process. Practical Steps for Nairobi Households Install a point-of-use RO system on your kitchen tap for drinking and cooking water. Reduce use of single-use plastic bottles, they are themselves a source of microplastic leaching. Schedule annual membrane inspections to ensure your RO system maintains its rejection rate. Filter water before it enters your kettle, which can concentrate particles during boiling. Q: Can boiling water remove microplastics? A: No. Boiling kills pathogens but does not affect plastic particles. You need physical filtration, ideally reverse osmosis, to remove microplastics. Q: Is bottled water safer than tap water for microplastics? A: Studies show bottled water can contain equal or higher concentrations of microplastics than tap water, partly from the bottle itself. A certified RO filter is a more reliable solution. Protect your family from microplastics iClear's RO purifiers remove 99%+ of microplastic particles at every pour. Find out more.

The Best Water Purifier in Mombasa

The Best Water Purifier in Mombasa

When evaluating water quality along the Kenyan coast, visual clarity means very little. The specific challenges facing Mombasa households are invisible to the naked eye but unmistakable to the taste. If you are looking for the best water purifier in Mombasa, you must first understand exactly what is hiding in the local supply.   The Coastal Borehole Challenge Many coastal properties rely on boreholes to supplement municipal water. iClear’s field testing reveals that coastal and arid-region boreholes are uniquely prone to high concentrations of dissolved salts. While inland areas like Naivasha typically record TDS (Total Dissolved Solids) readings between 300 and 600 ppm, coastal boreholes can climb significantly higher than these inland readings. Water with such extreme TDS levels is generally not recommended for drinking without extensive treatment, as it places a heavy burden on cardiovascular and kidney health. Mombasa's water has high TDS levels due to it's proximity to Indian Ocean   Why Standard Filters Cannot Handle Mombasa Water If you buy a standard gravity, ceramic, or carbon filter off the shelf, you are wasting your money on coastal borehole water. Carbon filters improve taste slightly and sediment filters trap sand, but neither can remove dissolved salts. Furthermore, boiling this water simply evaporates the clean water molecules, concentrating the remaining salts and making the TDS problem even worse.   The Reverse Osmosis Advantage The only effective water purifier for Mombasa's high-TDS environment is a Reverse Osmosis (RO) system. RO technology works at the molecular level; the membrane blocks the heavy dissolved salts, heavy metals, and bacteria that coastal boreholes harbor, while letting only pure water pass through. A high-capacity system like the iClear Premier (designed to deliver 100 gallons per day) or the widely utilized iClear Standard can dramatically reduce your TDS reading by 90% or more, transforming salty, borderline-unsafe water into genuinely pure drinking water. You can also schedule a comprehensive water test to get exact readings for your coastal property. Find out what is actually in your water.

Moving Into a New Home in Nairobi? Check the Water First

Moving Into a New Home in Nairobi? Check the Water First

Relocating to a new house or apartment in Nairobi involves a long list of priorities: painting, shifting furniture, setting up internet, and organizing security. However, one critical element is frequently overlooked until after move-in day: checking the quality of the property's drinking water. Water quality in Nairobi varies dramatically from one estate to the next, and assuming a new home has clean water can lead to serious health issues and unexpected costs.   What You Inherit Depending on the Location When you move into a new Nairobi neighborhood, your water profile is determined by local infrastructure and groundwater geology: 1. Premium Suburban Neighborhoods (Karen, Runda, Lavington) Many renters and buyers assume upscale addresses come with pristine water. However, Karen and Runda rely heavily on private property boreholes. While TDS levels are moderate (150 to 180 ppm), deep groundwater carries elevated calcium, magnesium, and dissolved iron that scale kettles and alter beverage taste. 2. Densely Populated Estates (Embakasi, Donholm, Buruburu) In Eastlands, municipal water supply is highly intermittent. Landlords rely on large underground and overhead storage tanks that are rarely cleaned. Water sitting in these tanks gathers rust, biofilm, and sediment sludge that flows directly into your apartment's taps. 3. Commuter Suburbs (Kitengela, Syokimau, Kajiado) If you are moving to Kitengela or Syokimau, municipal water is scarce, and boreholes dominate. Water here measures at high TDS levels (450 to 600 ppm) and frequently carries high fluoride levels. Unfiltered water in these areas tastes salty and poses long-term dental risks for children.   The Move-In Water Audit Checklist Before settling into your new property, run through these four practical checks: Ask the Source: Is the property connected to municipal water, a private borehole, or a commercial water tanker service? Inspect the Storage Tank: Look inside the roof or ground tank. Is there visible sludge at the bottom, or algae along the walls? Check the Tap Fixtures: Look for white crusty deposits (limescale) or reddish-brown rust stains on the taps and sinks. Taste and Clarity Test: Does the water taste salty, metallic, or chemical, even if it looks visually clear in a glass? The 30-Minute Water Upgrade You cannot change your landlord's plumbing or the neighborhood's underlying geology, but you can control what comes out of your drinking tap. Installing an iClear Standard under-sink Reverse Osmosis system takes just 30 to 45 minutes on installation day. Our professional technicians assess your plumbing, mount the system, flush the filters, and connect a dedicated stainless-steel faucet directly to your sink counter.
