I read somewhere that there is a big water project which was to be commissioned at Kiserian today.If this is the case would it make sense to sink a borehole?

So far, I have drilled two boreholes In Loitokitok area.
Cost varies , depending on the soil structure and also how deep down the borehole will go.I paid approx 6000 shillings for one metre and my borehole was 90m deep. Came to about 540,000. Then there is casing which is done and mobilization fee, and blah blah and it came to around 1.2m. That is drilling ONLY. After drilling you have to equip the borehole and that involves getting a submersible borehole pump which can cost anywhere from 100k-400k. There are riser pipes , control panel, wiring etc. to be considered. First thing you have to do is get a Hydrogeologist who will give you a Hydrogeological Survey Report after a site visit which is a booklet showing the soil structure, the water table, nearby boreholes etc. Will cost you 50k-100k . I can hook you up with a friend. After the HSR you apply for a Water Permit from WARMA. Armed with the HSR and the Permit then you can approach the drillers for a quotation.

Thanks people, this has been quite useful.

I did one the year before last. Wasn't too deep @55 feet.

There's the kienyeji way and the procedural way. Procedural is where you do an Environmental Impact assessment ya NEEMA, Hydrogeological survey, get necessary approvals, then dig. Depending on the area, there are places, like my place where it pure rock from surface, so those vehicle machines are preferred. At mine, I got guys with a modified maize milling machine, with a drill bit ya 'diamond' hapo mbele. I negotiated to 1k per foot, casing was around 3-4k, borehole metal housing 2k, fundi to mason it 1k+1k material. Electrician fitting pump 3k, circuit board+ circuit breakers+switch+cables+pump 30k - 40k.

Of importance is the testing phase. Let the pump run a few hours (overnight if possible) as you check the water being pumped out. Quality and quantity, before releasing the contractors, else you might cry when your bore-hole runs dry on you and damages your electricals.

That's more of a well than a borehole?Who did you use to determine water availability underground?And does it have water throughout the year?
