Estate Water Security Upgrade with Dual Boreholes
Commercial Project | Gated Estate
Project Overview
Client Challenge
A fast-growing gated estate with multiple housing phases depended on an undersized single borehole and irregular municipal supply. Storage capacity and pumping configuration could not keep up with peak morning and evening demand, resulting in rationing, low pressures and frequent tenant complaints.
AKO Solution
AKO designed and implemented a dual-borehole system feeding shared elevated and ground-level storage tanks, served by duty/standby pumps. A pressure-managed ring-main distribution network with zoning by elevation was introduced so that all blocks receive consistent pressure even as future phases come online.
Engineering Considerations
Hydraulic modelling informed the location of pump stations, non-return valves and pressure-reducing valves, minimising friction losses and water hammer. The design allows one borehole to be taken offline for maintenance without disrupting supply, and provides clear metering points so management can track consumption by zone and plan for further expansion.
System Specs
- • Two production boreholes
- • 200,000 L storage
- • Duty/standby pumps
- • Zoned ring-main
Results
- • Zero outages (12 months)
- • No water rationing
- • Future-proof design
- • Transparent metering
Where AKO Has Done Similar Estate & Residential Projects
AKO has supported estates, gated communities and mixed-use developments around Nairobi and its environs (including Kiambu, Ruiru, Juja, Athi River, Ongata Rongai, Ngong and Limuru), as well as estate clusters in Nakuru, Naivasha, Kisumu and Mombasa. This gives our team a strong reference base for pressure zoning, storage configuration and redundancy in modern residential settings.
