2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Waterhole is excavated for abstracting underground water for watering livestock as well as irrigating crops during the dry season.
2.2 Detailed description of the Technology
Underground water abstraction is done by excavating a pit hole in the ground fixed and protected against collapse to reach water underground . A hole measuring 2-6 m deep , 2 m wide and 3 m long is manually dug in the ground/ soil and established far distant from the homes and near the streams to allow water to collect and come up . The hole is shaped in such a way that water does not flow out, and the top is covered to keep the water in the hole protected from contamination. The opening is covered with local materials like poles, bamboo stems (Bamboo aridinarifolia), etc. Water flows into the hole through various methods of groundwater recharge such as open wells, soak pits, and recharge shaft/ trench.
The activities involved in establishing such a underground water hole include (1) identifying suitable site for digging the hole, (2) looking for trainer or expert to advise on how to dig and cover the hole, (3) looking for labor, and tools (e.g. hoes, spades, poles, etc.), (4) digging the hole to a depth of about 2-6 m, de-pending on the level of water table, (5) protect the hole with bamboo or wood to ensure hygiene and from people falling in.
The returns derived from this technology include: an effective alternative water source during the dry season which is used for crop irrigation (e.g. maize – Zea mays; cabbage - Brassica oleracea) and for livestock production/ watering.
This technology is most preferred because it is cheap, affordable and easy to maintain. The only costs are at the establishment phase. Its main challenge is that it can be contaminated when managed poorly if animals are allowed to close to the hole. To ensure this, the farmer needs to keep in contact with the extension agent to ensure maximum proper management of the hole to minimize contamination.
In terms of impacts, the technology provides an effective alternative water source during the dry season, which is used majorly for livestock and irrigating crops.
Because the technology is promoted as a supplementary water source for the dry season, during the wet season grass may grow on top of the protected hole. Before its use in the dry season the land user removes the grass before abstracting the well water for crop production and 5 heads of livestock kept in distance of 50 m-100 m from the well.

General remarks regarding photos:
The grass left to grow does not imply poor management but a protection for a longer period leading to dry season when there is shortage of water.
