Sri Lanka faces a serious and growing water safety challenge. Only 30% of the population is served by the national water supply. Pure Life exists to fill this critical gap — scientifically, affordably, and reliably.
Sri Lanka's water infrastructure cannot keep pace with demand. Millions of citizens — particularly in rural and dry-zone areas — are drinking water that contains harmful contaminants daily.
The Sri Lanka Water Supply & Drainage Board covers only 30% of national water demand. It would take more than two decades at current rates to reach the remaining 70%.
Rural populations directly consume water from rivers, tanks, wells, and boreholes without any purification. These sources contain bacteria, heavy metals, arsenic, cadmium, fluoride, and agricultural chemicals.
13 districts have been designated as CKDU (Chronic Kidney Disease of Unknown Etiology) spreading areas. Scientists link this to contaminated drinking water in agricultural regions. Most victims are farmers.
Water with pH below 6.5 is acidic and corrosive — leaching toxic metals from pipes and causing health risks. Water above 8.5 is hard and scale-forming. Sri Lanka's groundwater frequently falls outside the safe 6.5–8.5 range.
Total Dissolved Solids above 500 mg/L are common in Sri Lanka's groundwater. Water above 1,000 mg/L is unfit for consumption. High TDS causes bitter taste, appliance damage, and carries toxic ions like lead, nitrate, and arsenic.
Children are far more sensitive to water contaminants than adults. Their immune and defence systems are still developing. Contaminated water causes disproportionately severe health outcomes in children — including developmental issues.
pH measures the acidity or alkalinity of water on a scale of 0–14. Pure water is pH 7 (neutral). The ideal drinking water range is 6.5 to 8.5 — as defined by Sri Lanka Standards SLS 614:2013 and WHO guidelines.
Acidic water (pH < 6.5) is corrosive, leaches metals from pipes, causes a metallic taste, stains sinks blue-green, and carries elevated levels of toxic metals including iron, manganese, copper, lead, and zinc.
Alkaline water (pH > 8.5) creates hard water problems — scale on dishes, difficulty lathering soap, scale buildup in pipes and appliances, and an alkali taste.
TDS measures all organic and inorganic materials dissolved in water — including minerals, ions, metals, and chemicals. Sources include minerals in treatment chemicals, road salt runoff, agricultural fertilizers, and natural rock formations.
High TDS affects taste (bitter, salty, or sulfuric), causes hard water, leaves spots on utensils, fades clothing, builds up in sinks and pipes, and may carry dangerous toxic ions.
Sri Lanka standard SLS 614:2013 requires TDS ≤ 500 mg/L. Water above 1,000 mg/L is officially unfit for consumption. Pure Life filters bring TDS within safe limits.
| TDS Level (ppm) | Palatability |
|---|---|
| 50 – 150 | Excellent for Drinking ✓ |
| 150 – 250 | Good |
| 250 – 300 | Fair |
| 300 – 500 | Poor — SLS limit |
| 500 – 1,000 | Unacceptable |
| Above 1,200 | Unfit for Consumption ✗ |
Sri Lanka's water sources — particularly in agricultural and dry-zone areas — contain numerous contaminants that exceed safe limits. These include both naturally occurring minerals and man-made pollutants.
Toxic ions like arsenic, cadmium, lead, and nitrate are particularly dangerous, especially for children and pregnant women. Agricultural runoff introduces pesticide residues and fertilizer chemicals. Old pipe infrastructure introduces rust, scale, and lead.
Seven specialized Korean-engineered filter stages working in sequence to transform contaminated tap or well water into SLS 614:2013 compliant drinking water — without electricity, chemicals, or water wastage.
Compact, point-of-use water purifiers for individual families. No electricity, no plumber required for basic installation. Fits under any kitchen bench or countertop.
Large-scale water purification plants designed to supply entire villages and underserved communities — a sustainable, shared-infrastructure approach to safe water access.
Unsafe drinking water is a root cause of numerous preventable diseases. Pure Life's multi-stage filtration removes the contaminants that cause these health conditions.
