Anyone who has done it lately. Any particular company you can recommend. What Are the expected challanges. Saidieni tafadhali 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. could you provide more information on this type of drill please?

The title of this thread is a bit confusing Is it sinking or drilling a borehole, From my limited interaction with capital Fm presenters, drilling a borehole and sinking a borefole are two different things with two different outcomes If Obiero did it, Who Am I?

Bwana Chaka, sorry to say this but I think you do more talking and less reading. I suggest you read what I wrote slowly and do your own research, before being presumptuous. For what its worth, I have BOTH a well and a borehole. Proponents of a well will argue that a well is better because if the water quantity reduces, you can always get a digger to climb back down and extend it, at a much cheaper cost. However, a well done borehole, with sufficient (maximum) depth and a well done casing SCREEN (kichungi cuts they make, sometimes incorporating gravel), to keep the mud out and stop it from blocking and collapsing, can serve you a lifetime. @Mkenyan, those machines are rather common among hustling borehole-diggers and there are people who hire them out. Infact what those 'hustlers' do is look for tenders, rent the machine, drill then take it back. The kienyeji way would have you checking the nearest borehole to determine average depth you'd be expected to drill

So which companies or Hustlers do the drilling. Can someone please recommend.

Yes. 55 is lucky. I have another I intend to dig at circa 20 feet. The thing with wells, sometimes the water you get isn't sufficient enough to sustain profitable farming. With a borehole you can go deep enough to get as much water as you want. The quality of water is something of consideration.. Well water can be very dirty water, with foot valves spoiling every so often, often having to wash tanks etc @Rongla, where will the borehole be done?

Please avoid such. You can try Mr.Gachanja, 0720999333, the owner of Balena Drilling. Very professional guy with a Great team. Did my high yield borehole all the way to 70m (230 feet). Never runs out of water throughout the day at 30,000 litres per hour pumping. Charges 6k per metre. @SufficientlyP
