What is (RO) Reverse Osmosis?

Reverse Osmosis (RO) is a water purification method that pushes water through a very fine filter. This filter blocks dirt, chemicals, bacteria, and even dissolved salts. It's one of the few systems that can turn salty water and borehole water into clean, safe drinking water that tastes fresh and sweet.

Removes salts Removes bacteria Removes chemicals

99.9% Purification rate

Why reverse Osmosis

RO removes both visible impurities and invisible contaminants like salts, fluoride, chemicals, and bacteria. It is powerful enough to purify salty water, hard water, borehole water, municipal water — basically any type of water — and make it safe for drinking and cooking in Kenyan homes.

How Often Should You Test Your Borehole Water in Kenya?

Kenya Water Act 2016 and KEBS KS 459 recommend testing private borehole water for bacteriological quality at least twice per year and for full chemical quality annually. The Set-and-Forget Mistake When a borehole is drilled and certified, owners often file the initial water quality report and assume no further testing is needed. But borehole water quality is not static. It changes with season, with changes in land use around the borehole, with ageing infrastructure and with the water table. A study of peri-urban boreholes in Kiambu County found that 44% of boreholes that passed their initial certification showed elevated coliform counts within 18 months. Source: Groundwater Quality Assessment in Kiambu County, Chuka University Repository. Recommended Testing Schedule Test Type Frequency What It Detects Bacteriological (E. coli, coliforms) Every 6 months Recent faecal contamination Physical-chemical (pH, TDS, hardness, nitrates) Annually Mineral imbalances, agricultural contamination Heavy metals (lead, arsenic, fluoride) Every 2–3 years or after change in local land use Industrial or geological leaching Pesticide residues After rainy season or nearby agricultural activity Agrochemical runoff Key Triggers for Unscheduled Testing Any flooding or significant rainfall event that reaches the borehole head. A change in the taste, colour or odour of the water. New construction, fuel storage or farming activity within 50 m of the borehole. A new household member joins who is immunocompromised, pregnant or an infant. Unexplained gastrointestinal illness in regular users. Where to Get Your Borehole Tested in Kenya Accredited laboratories for water testing include Kenya Water Institute (KEWI) in Nairobi, the Public Health Laboratory Services Branch labs in county hospitals, and several private analytical labs registered with the Kenya National Accreditation Service (KENAS). Source: Kenya Water Institute, Water Quality Testing Services. What Happens After Testing? If bacteriological contamination is found, the first step is to check the borehole casing for cracks or a loose wellhead seal. The borehole can be shock-chlorinated to disinfect the system, after which re-testing confirms effectiveness. For chemical contamination, the appropriate treatment depends on the specific parameter, RO filtration handles a broad range including nitrates, heavy metals and pesticides. Q: Is borehole water automatically safe because it comes from underground? A: No. Shallow boreholes are especially vulnerable to surface contamination. Even deep boreholes can have naturally occurring fluoride, arsenic or other minerals at levels above safe limits. Q: Can I test my borehole water myself? A: Home test kits provide a rough bacteriological indication but are not accredited for official purposes and may miss important chemical parameters. Laboratory testing from a KENAS-accredited facility is recommended for reliable results. Pair testing with reliable purification iClear's RO purifiers provide consistent protection between your scheduled borehole tests. Find out more.

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

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.
