The story
Water kept underground stays cool and dark, and the yard above it stays yours. The tank is one piece of UV-stabilised polyethylene, ribbed for strength, with walls 8 to 14 mm thick.
Fill it from the roof, a borehole or the county line. When one is not enough, join a second, or a fifth.

Questions about the 5,000 L underground water tank
How long does 5,000 litres last a family?
As a rough guide, a family of five using 50 litres each a day draws 250 litres, so a full tank lasts about 20 days with no other supply.
Can I join tanks for more water?
Yes. They connect in series or in parallel: two give 10,000 L, three 15,000 L, up to five for 25,000 L.
Can it go under a driveway?
Not on its own. ROTO's guide says a tank under traffic needs a concrete relief slab, and the walk-on lid takes people, not vehicles. Your engineer confirms the details for your site.
Do you install the tank?
No. Kewat delivers the tank; digging and plumbing are done by your own contractor. We share ROTO's installation guidance, which your engineer confirms for your site.
How is it delivered and paid?
Delivery is quoted per trip and the tank reaches you within 3 days of payment, or you collect it from our head office in Baba Dogo, Nairobi, after 2 days, or from our factory in Naivasha. Payment is by M-Pesa or bank transfer, 100% before delivery; credit for businesses and government by written agreement.
