Irrigation in Lamu County
Lamu County is coastal smallholder country — maize, rice, cassava, green grams, cowpeas, mangoes, coconut, cashew nuts, kale, tomatoes, capsicum, citrus and bananas on mixed farms that run mostly on rain, with irrigation as the dry-season backstop rather than the everyday system. The design question here is usually the source: boreholes, shallow wells, seasonal rivers and irrigation schemes carry the county's irrigated blocks, and the design starts from what each one actually yields.
Irrigation needs in Lamu County
Government-backed irrigation sites around Mpeketoni and Witu put smallholder vegetable blocks under formal irrigation on a mixed-farming base that otherwise runs on rain and shallow groundwater. That mix of sources — some reliable, some seasonal — is the reason a proper assessment matters more here than a standard template: two farms a few kilometres apart in Lamu can be on genuinely different water pictures.
The crop range is the coastal mix: maize, rice, cassava, green grams, cowpeas, mangoes, coconut, cashew nuts, kale, tomatoes, capsicum, citrus and bananas, mostly at smallholder scale. The smallholder pattern covers the typical setup; the orchard pattern applies to the tree-crop blocks (mango, coconut, cashew, citrus). The water quantity guide is the method for sizing against a borehole, dam or rock-catchment source.
Crops we design for in Lamu
- Maize — the county's best-known crop here, and usually the first block a farm puts on drip.
- Rice — a steady smallholder crop, typically on the two-line bed pattern once water is metered.
- Cassava — grown widely across the county's farming areas, sized against whatever source the farm actually has.
- Green grams — a common second crop on the same plots, sharing the farm's water source with the main block.
- Cowpeas — grown where the terrain and water allow it, usually at smaller scale than the county's main crops.
Water sources in Lamu County
| Source | Typical role | Filtration & notes |
|---|---|---|
| Boreholes | A working source in Lamu — the assessment measures its dry-season yield before the design is sized | Sand/media + disc; the intake protected from silt and organic load |
| Shallow wells | A working source in Lamu — the assessment measures its dry-season yield before the design is sized | Sand/media + disc; the intake protected from silt and organic load |
| Seasonal rivers | A working source in Lamu — the assessment measures its dry-season yield before the design is sized | Sand/media + disc; the intake protected from silt and organic load |
| Irrigation schemes | A working source in Lamu — the assessment measures its dry-season yield before the design is sized | Sand/media + disc; the intake protected from silt and organic load |
Government-backed irrigation sites around Mpeketoni and Witu put smallholder vegetable blocks under formal irrigation on a mixed-farming base that otherwise runs on rain and shallow groundwater. The assessment is where that gets measured on your specific farm rather than assumed from the county average.
How we design for Lamu County
From the farm's own source and crop plan — in a county with this much variation in water sources, that assessment step is where the real design decisions get made. The design and install run the standard chain; the cost guide has indicative ranges. The maintenance service covers the filter and line routine that keeps a rock-catchment or dam-fed system running through the dry months.

FAQ
Lamu County irrigation questions
What crops are grown in Lamu County?
Lamu County's main crops are maize, rice, cassava, green grams, cowpeas, mangoes, coconut, cashew nuts, kale, tomatoes, capsicum, citrus and bananas. Government-backed irrigation sites around Mpeketoni and Witu put smallholder vegetable blocks under formal irrigation on a mixed-farming base that otherwise runs on rain and shallow groundwater.
Is drip irrigation worth it for a small farm in Lamu?
Usually yes on the higher-value crops — maize and the other blocks the county is known for repay a metered water supply through better, more consistent yield. The cost guide has indicative ranges, and the assessment measures the farm's actual source and layout before anything is quoted.
What water sources work for drip irrigation in Lamu County?
Boreholes, shallow wells, seasonal rivers and irrigation schemes are the working sources here. Each carries a different filtration need — the filtration guide covers the setup, and the water quantity guide is the method for sizing a system against what the source can actually deliver in the driest month.
Where in Lamu County do you install?
The county's farming areas — Lamu East and Lamu West — and the Lamu town area. Send the farm's location and we'll confirm coverage and arrange the assessment.
