We stand in the gap through philanthropy to assist alleviate poverty, disease and ignorance through provision of charity water projects in needy rural and urban communities in Africa.

 

  1. Sand dams/ water pans in Kenya for communities

Although design and construction of dams in different areas shows some variability, as each site is different and the design has to be modified accordingly, all dams have a similar basic design. Rivers vary in width and discharge, rock foundations vary in depth and susceptibility to leakage, riverbanks may be high or low. The location of a sand dam should be chosen such that: it is feasible on technical grounds, it has high storage capacity and it is convenient to the community using it. We have come up with strategies in constructing these where we use dam liners to ensure water gets retention of up to 70%. These are fairly low in terms of construction costs and range from as low as US$48,000 for a moderate water pan and US$95,000 for a large water pan, depending on water catchment area and size. A bill of quantities is required. These water pans will serve the community for ten years before they can be rehabilitated.

2. Mature dam construction

River catchments are utilized with the help of cooperatives and organized groups, to tap huge reservoirs and convert them into major mature dams. These help harvest tons of water during rainy seasons. Advantages are many such as growing economic activities, like horticulture, irrigation, brick making and bee-keeping, water for construction, water for animals, which are all activities related to water use from storage dams or to timesaving as water is readily available. The long term advantage is alleviation of poverty and food security. These are the most costly to construct but serve larger populations. A good dam can serve a whole division and a good dam will cost as from US$985,000 upwards depending on water catchment area and storage capacity objectives. A medium sized dam costs about US$1,500,000- 2,000,000 and a large size dam costs up from US$2,500,000- 3,000,000. Bills of quantities are required and we normally present these on all projects. A good dam properly constructed will last 20 years and only maintenance, desilting will be occuring.
