Drilling is reliable, it is a better quality water source, though the cost of drilling is high considering all standards. Better drill in the dry season else when u dig sometimes u think u have hit the water bed yet it ain't it.
Drilling is expensive(consinder 25m-40m, if the Site is about 35km from Kampala). But Water is reliable for all generations.
Digging boreholes is inexpensive(consider Btw 4m-8m, if Site is less than 35km from Kampala)· its Water somestimes may not be reliable in the Dry season especially for commercial use.
The only difference is that drilling is expensive compared to digging, but drilled water is way too reliable through out all weather conditions
A shallow well can be dug manually. It usually stops at a depth of about 10 - 30m.
The preference on the two is dictated upon by the quality and quantity of water, design and cost of construction, purpose of the well and pumping system.
For domestic use, the water from the hand-dug shallow well would suffice, if well treated and protected. But the quantity may not be of constant supply (because the water comes from underground springs that may dry up during drought). Hand-dug wells, if constructed and installed with solar pumps, would cost you around UGX 6M/-
However, for agricultural or community consumption, a borehole would be more reliable for both quantity, constant supply and even quality (Borehole water comes from aquifers/cracked rocks). But drilling is much more expensive. Drilling a borehole and installing submersible solar-powered pump would cost around UGX 28 - 34M/-. But you would use it for more than 30years with constant supply of water before repair or replacement.
