Borehole Assessment & Pump Selection

This service is about choosing the right borehole pump before things go wrong. We assess the borehole, look at how much water it can realistically deliver, and select a pump that will run reliably without damaging the borehole or itself. This is the step that prevents dry-running, overloads, and premature pump failure. We don’t guess sizes — we match the pump to the borehole and the job it needs to do.

What this service includes

Assessment of borehole depth, yield, and water level behaviour
Review of existing borehole information and test data (where available)
Evaluation of site demand, required flow, and pressure
Correct pump sizing based on head, duty point, and borehole limits
Selection of suitable pump type and motor size
Determination of correct installation depth
Specification of required protection and control equipment

What this service does not include

Borehole drilling, flushing, or rehabilitation
Water quality treatment or filtration design
Installation work unless combined with pump setup or replacement
Items listed above may be handled as separate follow-up work where required.

This service is suitable for

New boreholes needing the correct pump from the start
Boreholes where the existing pump is undersized or oversized
Pump replacements where the previous selection caused failures
Systems that trip, run dry, or underperform due to incorrect pump choice
Situations where no one is confident the pump is actually right

How the work is done

Review available borehole information and site requirements
Assess expected yield and operating water levels
Calculate total head and realistic delivery capacity
Select a pump that matches both borehole limits and site demand
Define correct installation depth and operating range
Specify protection and control to suit the pump and borehole
Explain the selection clearly and prepare for installation or replacement

Problems this service fixes

Borehole pumps that are too powerful for the borehole
Pumps running dry and overheating
Low flow caused by incorrect pump selection
Repeated electrical trips or overloads
Short pump lifespan due to operating outside design range
Replacement pumps chosen without proper assessment

What you can expect

A pump correctly matched to the borehole and demand
Reduced risk of dry-running and premature failure
Stable and predictable borehole performance
Clear understanding of what the borehole can and cannot supply
A solid foundation for installation or replacement work

What we need to do the work

Basic borehole details are required, including depth and any available yield or water level information. Site requirements such as desired flow, pressure, and delivery points are needed to complete the assessment accurately.

Limitations

Pump selection is limited by borehole yield and recharge rate. Seasonal water level changes can affect long-term performance. This service cannot improve borehole yield or guarantee water availability.
