Water Engineering
Water supply, drainage and treatment engineered for a country where water security cannot be assumed.
Overview
What our water engineering service covers
Water is where many Kenyan developments quietly fail — supply that cannot meet demand, drainage that floods, or wastewater that becomes a compliance problem. We design the systems that prevent those outcomes: borehole and abstraction design, distribution networks, stormwater drainage, rainwater harvesting, and wastewater treatment.
Water resource engineering is one of our core specialisms rather than a bolt-on, which means supply and drainage strategy is set early in a project, when it is still cheap to get right.
Why engage us
Five reasons clients bring water engineering to TopHall
Water-resource engineering as a core discipline
Our team includes engineers specialising in water resources, so this is designed properly rather than delegated to whoever is available.
Designed for real demand and real scarcity
Systems are sized against actual projected demand and the realities of intermittent supply, including storage and resilience.
Regulatory approval built into the design
Designs account for Kenyan water authority requirements and environmental standards, so approvals proceed without redesign.
Whole-cycle thinking
Supply, storage, distribution, drainage, and wastewater are designed as one system, which avoids the mismatches that appear when each is procured separately.
Operating cost considered, not just capital cost
Pumping energy, maintenance access, and treatment running costs are weighed in the design, because the cheapest system to install is often the most expensive to run.
How it works
Our process
Each stage has a defined output, so you always know what you are receiving and what happens next.
- Step 01
Demand assessment
We establish water demand, discharge volumes, and the site's hydrological context.
- Step 02
Source & strategy
Supply sources are evaluated — mains, borehole, harvested rainwater — and a strategy is set.
- Step 03
System design
Distribution, storage, drainage, and treatment are designed and sized.
- Step 04
Approvals
Documentation is prepared for the relevant water and environmental authorities.
- Step 05
Construction support
We support installation and commissioning to confirm the system performs as designed.
Questions
Frequently asked questions
Do you handle borehole drilling as well as design?
We design borehole and abstraction systems and support the works through construction. Talk to us about your site and we will set out exactly what we take on and what is subcontracted.
Is rainwater harvesting worth it in Nairobi?
It often is, particularly where it offsets stored supply and reduces stormwater discharge at the same time. Whether it pays back on your specific project depends on roof area, demand profile, and storage cost — we will model it rather than assume.
Can you design wastewater treatment for a development not on mains sewer?
Yes. On-site wastewater treatment is part of our water engineering work, designed to meet discharge standards for your location.
