Your Home. Your Water. Your Power.

A typical residential borehole in Nairobi and surrounding areas costs between Ksh 400,000 and Ksh 1,200,000, depending on the depth required and the geology of your plot. Key cost components include the hydrogeological survey (Ksh 30,000–60,000), drilling at Ksh 3,500–6,000 per metre, casing and gravel pack (Ksh 80,000–150,000), and the submersible pump and rising main (Ksh 60,000–200,000). Most Nairobi plots reach water at 40–120 metres. We provide a fixed-price quote after our free site assessment — so you know the exact cost before any work begins.

A properly sited and hydrogeologically surveyed borehole is reliable throughout the year in most parts of Nairobi and Central Kenya — including during dry seasons. Boreholes draw from deep aquifers recharged over many years. We protect your supply through three measures: first, a hydrogeological survey to identify the correct aquifer before drilling; second, pump sizing set below the borehole's sustainable yield; and third, a storage tank sized to buffer 2–3 days' supply. Most of our residential boreholes have been operational for 10–20+ years with no dry periods.

The right system size depends on your actual household consumption, which we assess during our free site visit. As a general guide: a 3-bedroom house needs 3–5kW (saving 60–80% on KPLC), a 4–5 bedroom home needs 5–8kW (saving 70–85%), and a large home or home office needs 8–15kW (saving 80–95%). We size systems based on your actual 3–6 month KPLC bills, not guesswork. A grid-tied system is the most cost-effective starting point; battery backup can be added later if needed.

It depends on your system type. A grid-tied system (no battery) automatically shuts down during blackouts for safety. A hybrid system with battery backup continues supplying power to your home during blackouts, switching seamlessly within milliseconds — we recommend a minimum 5kWh battery to cover essential loads (lights, fridge, security, phone charging) for 6–8 hours. A fully off-grid system operates completely independently of KPLC. For most Nairobi homeowners, a hybrid system with 5–10kWh of battery delivers the best balance of cost and blackout protection.

Yes — this is our most popular residential package. An Integrated Home Water & Solar Solution bundles borehole drilling, solar-powered pump, water storage tank, water treatment, rooftop solar PV, and optional solar water heater and battery backup — all under one contract, one fixed price, and one 2-year warranty. Bundled projects typically save Ksh 80,000–200,000 compared to contracting each element separately. See our Integrated Solutions page for full details.
