WFEA
Well Field Energy Audit

Well Field Energy Audit – want to save 30-50%?
Extracting groundwater from well fields represents up to 40-50% of the total energy consumption when supplying groundwater to the public
A WFEA provides an overview of the entire system’s energy savings potential
Includes everything from initial pressure loss calculations to final recommendations for improvement (see more details in the next slides).
Recommendations can include replacing old pumps, replacing over-sized pumps, or the use of frequency drives

Well Field Energy Audit

Haderslev Municipality
Vojens Waterworks – Denmark
Extraction: 560.000 m3/yr
Savings: 44 MWh/yr = 34%
Payback: 3,3 year

Jelcz-Laskowice – Poland
Extraction: 0,92 mill. m3/yr
Savings: 133 MWh/yr = 55 %
Payback: < 2 years

Galten – Denmark
Extraction: 310.000 m3/yr
Savings: 28 MWh/yr = 53 %
Payback: < 2 year

Loosdrecht – The Netherlands
Extraction: 2,9 mill. m3/yr
Savings: 55.000 kWh/yr = 21 %
Payback: < 5 year
The challenge
The Dutch drinking water supplier Vitens committed to an energy saving target asked Grundfos to improve efficiency at one of its plants
Grundfos provided a Pump Audit and Well Field Energy Audit
The solution
Although the plant proved relatively efficient, Grundfos saw its submersible pumps were oversized
These were replaced with correctly sized SP125 versions that use 21% less energy

Strib – Denmark
Extraction: 200.000 m3/yr
Savings: 24.000 kWh/yr = 48 %
Payback: to be calculated
