Thank you for your help on this. We are preparing to sign the consent decree soon. There will be a few small changes on our part as most of the CD follows our current NPDES permit.
I will be working on drafting the ERP for the WWTP over the next few days. I hope to have a draft out to everyone (including you to review) by Friday. We are planning to have this in place prior to signing the CD so we are not in violation from the get go.

Hi Jennifer,
Pump 1: 112hp; 5800gpm at 51’ of total head; max flow is 4300gpm
Pump 2: 112hp; same as above
Pump 3: 50hp; 2400gpm at 49’ of total head; max flow is 8000gpm
Those gpm’s will vary throughout the day and night and weekends.
Pump 3 is relatively new; maybe a year to a year and a half ago. The other two I don’t know.
Hope this helps,
Jason
