The depth of boreholes may vary from area to area and depends on both geological and hydrogeological conditions.
From previous, our borehole drilling experience we have realised that the average zones for groundwater occurrence have been established to be between 40-85 metres.
Further, other data in areas where projects have been executed reveal that aquifers are penetrated in drilling range from 25-85 metres.
(An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials.)
The average depth of boreholes in Northern Province is between 35-50 metres.
For Nakiso Borehole Drilling for cost estimation uses the depth of 40 metres.

Five Facts About Borehole Drilling That You Need To Take Note Of:
1. Know Your Borehole Casings:The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.
2. Borehole Drilling Depth: The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).
3. The Is No 100% Guarantee On Water: It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.
4. Borehole Siting or Water Surveying Is Important: Making use of a hydrologist or traditional water diviner will increase your chances of having a successful borehole that will yield a sufficient amount of water.
5. Know The Risks: The risk of the borehole drilling lies with the property owner. The client will still be liable for the drilling costs irrespective of a borehole yielding water or not.
