To our esteemed clients,
Borehole drilling is procedural and in most occasions people misinterpret or rather ignore the required procedures which is against the laid down rules and regulations by Ministry of water. Today we would like to enlighten you about the procedures involved.
Below is detailed summary of the procedures in order.
1. Hydrogeological survey.
Hydrogeological survey or Geophysical survey is usually conducted by a hydrologist or hydrogeologist to determine the geological formation of the area, location of water-bearing rocks (aquifers) and depth of the borehole to be drilled. It's a technical job that requires skilled and qualified hydrologist / hydrogeologist for better data collection and analysis. The cost usually ranges between Kshs. 40,000 to 100,000 depending with the location and geological formation of the area.
2. Environmental Impact Assessment
Abbreviated as EIA, is an assessment conducted to determine whether the project is environmental friendly or not. And if not, it provides for the environmental friendly options that curb the negative impacts f the project and thus promoting environment conservation.
3. WRA ( Water Resources Authority) permit application.
It's a requirement that one obtains an authorization for drilling and borehole license from the Water Resources Authority office located within the region of the project. A client pays a total of Kshs. 12,500 to WRA Paybill or deposits the money to WRA bank account. Kshs. 5,000 for drilling authorization and Kshs. 7,500 for borehole license. A client is required to submit a copy of ID, Title deed and KRA pin attached to two copies of hydrogeological survey reports.
4. Borehole Drilling.
After all the necessary permits and licenses have been issued drilling process commences. Drilling is a technique of ground breaking within standard and recommended diameter usually 12" . Drilling proceeds depending on the geological formation in the report until the maximum depth has been reached and aquifer has been struck as recommended in the hydrogeological survey data analysis report. Once the recommended depth has been drilled what follows is borehole casing and development.
5. Test pumping.
This is a yield test usually conducted after borehole drilling to determine the yield of borehole and size of pump to be installed. During test pumping, water is continuously pumped out of the borehole at a controlled rate for a minimum of 12 hours and a maximum of 24 hours. After test pumping water sample is collected for laboratory analysis to ensure its within World Health Organization (WHO) standard.
6. Pump Installation.
Pump Installation follows after test pumping is conducted because the report on the borehole yield will determine the size of pump to be installed, resting depth of the pump and the type of pump to install. Cost for this depends on the test pumping report.
7. Storage tank.
Storage tank come in different materials depending with the client's preference. These storage tanks range from steel tanks, PVC tanks and Concrete tanks which come with different capacity depending with the client's choice. Storage tanks help in storing water for long which in turn enhances pump efficiency since the pump might develop mechanical breakdown if it pumps water constantly.
