Pumping Tests
Know what your well can deliver before you size the pump and pipes.
About this service
A pumping test confirms that a well meets its design demand. We run step-drawdown and constant-rate tests, record water levels through drawdown and recovery, and interpret the results to find the sustainable yield and the aquifer parameters your engineers design from.
Who it is for: Clients who need verified well performance and aquifer parameters
What you receive
- Pumping test report with the recommended pumping rate
Where it fits in the well
The pumping test measures the two water levels in this drawing — the well at rest and the well under load — and turns them into a recommended pumping rate.
What is included
- Step-drawdown and constant-rate tests
- Water-level monitoring and recovery analysis
- Aquifer parameter estimation
- Sustainable yield assessment
How we work
- 01Step-drawdown test to find the safe pumping rate
- 02Constant-rate test to confirm the well sustains it
- 03Recovery monitoring after the pump stops
- 04Analysis and report
