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.

We have deep boreholes that run from 150 meters upto 400 meters deep. Other ways of collecting water is through construction of dams and through construction of water pans and sand dams.

  1. Sand dams/ water pans

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.

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 request.

3. Boreholes drilling and water tanks construction

Boreholes serve particular communities and provide for clean drinking water in some of these areas; however, not all arid areas have aquifers that retain water. In such cases, water pans are more convenient and advisable.
We provide services of geological surveys first to verify how deep wells or drill rigs will go before we can adequately give an idea of what costs for drilling water will be. Costs for water drilling in Kenya can be enormous but with the right technical advice one can greatly reduce these costs and that's where we come in. After the geology survey, we proceed to quantify costs needed, tools and personnel and the quest for water drilling or wells drilling can proceed. Boreholes drilling costs range from US$55,000 upwards depending on the area.

4. Funding and sponsorship of construction of water tanks to various schools within the dry areas of Eastern Kenya. These water tanks serve as collection points for run off rain water from rooftops that will be stored for use by the pupils. Water tanks for storage normally cost from US$8,500 up to equivalent of US$15,000, depending on structure type. Water tanks come in handy as schools can harvest rain water and save the pupils the agony of having to ferry water to schools.
