[Equest-users] EUI info on sanitary lift stations

[Jeff Haberl]

FYI...



Energy measurements for College Station for the potable water side indicate about 1 Wh/gal for each gallon pumped. Both the potable water and sewage values are from metered data from the city (i.e., kWh and gallons). A report detailing this is posted on the ESL's web site.

Another local PNW firm has looked at this, though the data appears to be on the potable water side.  However, perhaps the concepts/signatures are applicable to your situation.

Check with the ASCE and/or the AWWA, sanitary engineering division.

In general, for College Station, the data shows about 3 Wh/gallon for overall sewage treatment. So , the number should be a fraction of this fur the lift station ..

Also worth taking into consideration the static head that the lift station is working against.  A pump station that is moving 10 MGD at 100 ft of head may use more energy than a pump station that is moving 20 MGD at 30 ft of head for instance.

I did some audits on two pump stations but was not able to find any national data that compared pump station energy use.

It also seems to me that EUI (energy/ft2 of building) is probably not an appropriate metric for this. The energy use is probably more dependent on how much stuff they move. Energy per ft3 (of ‘stuff’) might be more appropriate.

If it were me, I’d start my search with associated equipment reps – if anybody is aware of such studies or guidelines, I’d have to imagine some with the OEM’s are in that circle.

Grundfos has a lifecycle cost calculation tool on their website for their lift stations, and I recall them pushing the efficiency of their equipment in their literature and presentations – you might try them specifically to see if they have performed any case studies of their own, or are otherwise aware of any broader annual energy consumption data.

Does anyone know of a source for EUI comparative data for municipal wastewater lift stations?
