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.

Water Rationing in Kenya: How Intermittent Supply Affects Water Quality

When municipal water supply resumes after a rationing period, the pressure surge can dislodge biofilm, carry sediment and allow back-siphonage from stagnant sections of the pipe network. The first water to arrive should be flushed before use. Kenya's Water Rationing Reality Intermittent water supply is a daily reality for millions of urban Kenyans. Nairobi Water and Sewerage Company operates a zonal rationing schedule in most areas of the city, with many estates receiving piped water for as little as 3–4 days per week. During drought periods, which have intensified under climate change, rationing schedules tighten further. Rationing means pipes in the distribution network are alternately pressurised and depressurised, a cycle that creates specific and well-documented risks to water quality. Three Quality Risks Unique to Intermittent Supply 1. Back-siphonage and intrusion: When pressure drops to zero in a main, any breach in the pipe casing, a crack, a corroded joint, a leaking valve, can allow soil water or contaminated groundwater to be drawn in by negative pressure. When the main is re-pressurised, that intruded water is pushed to consumers. 2. Sediment mobilisation: Sediment settles in pipes during low-flow periods. The surge that accompanies re-pressurisation picks up and carries that settled sediment to taps, causing temporary elevated turbidity and the bacteria associated with it. 3. Stagnation in household storage tanks: During rationing periods, water stored in rooftop or underground tanks can stagnate. Bacterial counts in stored water increase significantly after 48–72 hours if the tank is not covered and regularly cleaned. Source: Intermittent water supply and contamination risk, Nation Africa; K24 Digital water coverage reports 2023. Practical Protective Measures Risk Protective Measure Notes Back-siphonage intrusion Flush tap 30–60 sec when supply resumes; use RO for drinking water Most effective combined approach Sediment surge Pre-filter installed at tank inlet; replace pre-filter after major turbidity events Protects tank and downstream system Tank stagnation Clean tank quarterly; keep covered with sealed lid; use within 48–72 hours Critical for households relying on storage Pressure surge damage Install pressure regulator on household inlet Protects appliances and joints The Case for Point-of-Use Treatment Because water quality in an intermittent supply system is inherently variable, it depends not just on treatment plant output but on the entire state of the distribution network, point-of-use treatment provides the most consistent protection. An RO system at your kitchen tap treats every litre regardless of what happened in the pipe network that day. Q: Why does my water sometimes smell like chlorine after rationing resumes? A: Utilities may increase chlorine dosing temporarily after re-pressurising a section of network to address bacterial contamination introduced during the low-pressure period. Carbon pre-filters in your RO system remove this taste and odour. Q: Should I empty my storage tank before rationing resumes? A: If your tank has been standing for more than 72 hours, drawing down to a low level before the fresh supply arrives reduces the volume of stagnant water mixed with fresh supply and speeds the turnover. Consistent quality, despite rationing schedules iClear's RO purifiers ensure your drinking water is safe regardless of what the distribution network delivers. Find out more.

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.

Biofilm in Your Household Pipes: The Contamination Risk Nobody Talks About

Biofilm, a community of bacteria embedded in a protective matrix on pipe walls, is present in virtually every plumbing system. During low-flow periods it can shed into drinking water. RO filtration at the tap eliminates this risk. What Is Biofilm? Biofilm is a structured community of microorganisms that attach to a surface and produce a protective extracellular matrix. In household plumbing, bacteria from the municipal supply or from the surrounding environment colonise pipe walls within days of installation. The matrix protects them from chlorine disinfection and from being flushed out by normal water flow. Research published in Frontiers in Microbiology identified over 2,000 distinct bacterial species in household plumbing biofilms across multiple countries, including potential pathogens such as Legionella, Pseudomonas aeruginosa, and Mycobacterium species. When Biofilm Releases Bacteria into Your Water Under normal steady flow conditions, biofilm remains attached to pipe walls. Detachment events, which can introduce biofilm fragments and free bacteria into your drinking water, are triggered by: Water hammer: sudden pressure surges when taps are closed quickly. Extended stagnation: water sitting in pipes overnight or during holidays provides no flow to carry away detaching fragments. Pressure fluctuations: common during water rationing and valve operations by the utility. Hot water at scalding temperatures (>60°C) followed by cold water can cause thermal shock and biofilm detachment. Pipe repair work upstream: pressure changes during repair operations dislodge accumulated biofilm over a wide area of the distribution system. Chlorine Resistance of Biofilm Biofilm is 1,000 times more resistant to chlorine than free-floating (planktonic) bacteria. The extracellular matrix acts as a physical and chemical barrier, reducing chlorine diffusion to the inner layers of the biofilm by 70–90%. This means that standard municipal chlorination levels (0.2–0.5 mg/L residual) are insufficient to eliminate established biofilm. The Point-of-Use Solution Because biofilm can be present in the entire length of distribution pipe between the treatment plant and your tap, treating water at the source (the utility) does not guarantee clean water at the tap. A point-of-use filter, particularly an RO system, provides a final physical barrier that removes bacteria, biofilm fragments and their metabolic byproducts at the point of consumption. Q: Is Legionella a real risk in Nairobi households? A: Legionella grows preferentially in warm water (25–45°C) and is most associated with hot water systems, cooling towers and showerheads. The risk is low in normal household cold-water systems but higher in hot water storage tanks not maintained above 60°C. Q: Can I remove biofilm from my pipes? A: Physical removal requires professional pipe flushing and hyperchlorination, a periodic maintenance task for large buildings. For household drinking water, point-of-use filtration is the practical protection. Clean water at the tap, always iClear's point-of-use RO system provides protection from biofilm bacteria regardless of what happens in your building's pipes. Find out more.
