Water Treatment for Apartments, Estates and Gated Communities in Kenya
Pictured: Frp filter tank and H-Tech 6GPM 25W UV Sterilizer.
Quick answer: Most apartment blocks treat water in two levels: whole-building treatment (sediment and media filters, a softener if the water is hard, and UV or chlorine for germs) and drinking water from an RO plant or a refill tap for residents. Clean storage tanks regularly and consider prepaid water meters to share costs fairly. UV units start from KSh 13,000 on H-TECH’s listings.
Key facts
  • Whole building: filter + UV
  • Softener if water is hard
  • RO for drinking water
  • Clean tanks; meter fairly

Step 1: Test the Water

Test the borehole or municipal supply for TDS, hardness, iron and bacteria (testing guide). The results decide which stages you need.

Step 2: Whole-Building Treatment

ProblemStage
Dirt, sand, cloudinessSediment / FRP media filter
Iron, rotten-egg smellIron removal filter (iron guide)
Hard water, scale on heatersWater softener
GermsUV sterilizer or chlorination

Step 3: Drinking Water

Treating all the water to drinking standard with RO is costly. Many blocks fit an RO plant feeding a residents’ refill point or a small water vending machine, so residents pay per litre.

Step 4: Tanks and Pressure

Step 5: Share Costs Fairly

Prepaid water meters let each unit pay for what it uses: prepaid meters for apartments and the cost recovery calculator.

Sizing Example

A 24-unit block using about 400 litres per unit per day needs about 9,600 litres a day of treated water. Size filters and the UV by flow rate (litres per minute at peak), not just daily volume (UV size calculator).

Frequently asked questions

How do apartments treat borehole water?

With sediment and media filters, iron removal if needed, a softener for hard water, and UV or chlorine for germs.

Should the whole building get RO water?

Usually not; RO for drinking water at a refill point is cheaper.

How often should apartment tanks be cleaned?

Every 6–12 months, or sooner if water quality drops.

How do landlords share water costs?

Prepaid water meters charge each unit for what it uses.

What size UV do I need for an apartment?

Size by peak flow rate; use the UV size calculator.
