The 6 step process on setting up a borehole:
- Carry out a geological survey to find a source of water.
- Once granted permission by the authorities, drilling process can begin. Boreholes are sometimes 250 feet deep.
- Pipes are then sunk and filtration system added.
- Electrical pumps, a control unit and a variety of electric motors and valves are set up at the surface.
- Debris is removed from the borehole by forcing water down the pipes and then back up.
- The purity of the water is tested before it is ready for use.
5 borehole drilling requirements:
- Borehole drilling licence from the Ministry of Water and Natural Resources.
- NEMA report, a mandatory requirement for environmental impact assessment test.
- Geological/hydrological survey done by a registered geologist. This is to give the accuracy of the depth of the water and the best site.
- Authorisation from the Water Resource Management Authority (WRMA).
- A water analysis report.
