Bob,
I will have Jason answer the following questions, just to make sure I don’t miss anything.
In regards to question #2, I would have to take a look at our WW facilities plan to verify what was planned to be constructed by 2025. Everything in the contract plans provided to you was completed. The project prior to this one constructed the effluent pump station and line to the Molalla River Discharge point. Those plans identified to install 3 effluent pumps, however only 2 were installed. Obviously with the storage capacity in the lagoons we can receive higher peak inflows than discharge on a daily basis, but only for short durations.

Jennifer,
Questions:
1. What is your current & projected wastewater flow?
2. The 2007 design shows a Peak Day Flow Design capacity of 8.5 MGD for 2015, with planned capacity of 10.3 MGD by 2025. Were all components for 2025 constructed?
3. Are you currently meeting your effluent quality limits?
4. Are there leaks from only 1 of the Sand Filters or more?
Thanks, BobS

Hi Bob,
Here are a few photos of the area around the gravity filter, just after the leak was discovered.

Hi,
Per our phone conversation, attached is the full plan set of the WWTP Improvements made in 2007. These plans include the construction of the sand filters. Filter #1 is in need of the repairs.
