Trust Partners Geo-Group is a leading dam and water pan contractor in Kenya, delivering engineered water storage structures for agriculture, livestock, irrigation, flood control and community water supply. From small waterpan construction on family farms to large earthfill dam construction and irrigation reservoir construction, we handle every earthworks scope with precision — dam site preparation, cutoff trench excavation, embankment construction, spillway construction and outlet works.
Our water pan excavation in Kenya is designed around your catchment. We carry out dam capacity calculation, catchment area design and water pan depth planning so your structure fills reliably and holds water through the dry season. Whether you need a water pan for agriculture in Machakos, an aquifer recharge dam in Laikipia, or a flood control dam in Nairobi, our fleet and engineers deliver on schedule. Read our complete guide on dam excavation and construction in Kenya for farmers and developers.
Every structure is built for longevity: layered embankment compaction, seepage control for earth dams, slope protection, riprap, grassing and fencing. For a detailed breakdown of structure types, see our comparison of dams vs water pans and our technical guide on seepage control and embankment stability for dams in Kenya.

Areas We Serve
Our dam construction and water pan excavation teams operate across Kenya, with deep experience in the semi-arid counties where water harvesting matters most. We deliver water pan and dam excavation in Eastern Kenya — Machakos, Kitui and Makueni — as detailed in our Eastern Kenya water pan and dam projects guide, and across Nairobi, Nakuru, Eldoret, Nyeri, Meru, Nyahururu, Kitale, Garissa, Naivasha, Kakamega, Embu, Kiambu, Nyandarua, Laikipia, Bomet, Vihiga, Murang'a, Bungoma, Nanyuki, Uasin Gishu, Nandi, Busia and Kisii.
Whether it is dam construction in black cotton soil, rocky terrain, or sandy ASAL soils, we adapt lining and embankment design to site conditions. Our county-by-county expertise is documented in our national guide to soil types and regional earthwork challenges, including Machakos, Makueni and Kitui semi-arid earthworks.
We also support agribusiness earthworks: irrigation canal excavation, feedlot and dairy site preparation, and farm terracing and land levelling to feed your water pan catchment.
Service Locations
Our Construction Process
From site survey to a full, commissioned water storage structure.
Site Survey & Design
Catchment assessment, dam capacity calculation, water pan depth planning and soil investigation.
Permits & Compliance
NEMA environmental impact assessment, Water Resources Authority permits and county approvals support.
Site Preparation
Bush clearing, topsoil stripping and dam site preparation using our site prep crews.
Excavation & Embankment
Cutoff trench excavation, layered embankment construction with compaction testing and core placement.
Spillway, Lining & Works
Spillway construction, outlet pipe installation, geomembrane or clay lining, toe drains and slope protection.
Handover & Monitoring
Riprap, grassing, fencing, dam instrumentation, first-fill supervision and maintenance guidance.
Capabilities & Structures
Every water retention structure type, built to engineered standards with our own fleet and operators.
All earthworks are delivered with our own heavy equipment hire fleet — excavators, dozers, graders and compactors with certified operators. Planning volumes? See our earthworks cost per cubic metre guide for Kenya.
Dam Safety & Compliance
Every dam construction project in Kenya we deliver meets NEMA and Water Resources Authority requirements. Our environmental impact assessment support, dam break analysis coordination and dam safety and compliance documentation protect you, downstream communities and your investment. Learn about contractor registration requirements for excavation works in Kenya.
Embankment stability is engineered, not guessed. We apply layered compaction with density testing, proper dam filter and toe drain construction, and slope protection through riprap and grassing. Our quality protocols follow the same standards outlined in our earthworks QA/QC and compaction testing guide and equipment quality assurance programme.
When you choose Trust Partners Geo-Group for water pan excavation or dam construction anywhere in Kenya, you get a partner with 15 years of earthworks excellence — see our 15-year track record — and a fleet managed with modern telematics and GPS machine control.

Read ArticleFrequently Asked Questions
Clear answers to help you plan your dam or water pan project in Kenya.
How much does it cost to build a water pan in Kenya?
Small waterpan excavation cost in Kenya depends on capacity, depth, soil type, lining requirements and site access — priced largely by earthworks volume per cubic metre plus embankment, silt trap, inlet and outlet works. We provide free site assessments and transparent quotations nationwide. For rate context, see our 2026 earthworks cost per cubic metre breakdown.
What is the difference between a dam and a water pan?
A dam is a larger engineered water retention structure — usually an embankment across a watercourse with a spillway and outlet works — while a water pan is a smaller excavated runoff harvesting structure for livestock, irrigation and domestic storage. Our dams vs water pans guide helps you choose the right structure.
How deep should a water pan be in Kenya?
Water pan depth requirements in Kenya typically range from 3 to 6 metres. Deeper pans store more water and reduce evaporation losses per litre stored — critical in semi-arid counties like Machakos, Kitui and Makueni. We calculate capacity against your catchment yield and water demand. See our size, depth and lining guide.
Do I need a permit to build a dam in Kenya?
Yes. Dam construction NEMA approval (via an environmental impact assessment), Water Resources Authority permits and county permits for water pan construction are required. We guide clients through the full compliance process, including dam break analysis coordination where required for larger structures.
How is seepage controlled in earth dams?
Seepage control for earth dams in Kenya combines a clay core, cutoff trench excavation to impermeable strata, dam filters, toe drains and — where soils demand it — geomembrane or clay lining. Read our detailed seepage control and embankment stability guide.
How long does dam construction take?
A small farm water pan can be excavated in days to weeks; larger earthfill dam construction with embankment, spillway and outlet works takes several weeks to months depending on capacity, terrain and weather windows. We issue a detailed programme after the site survey and dam capacity calculation, and can deploy rapidly through our equipment fleet.
