RE: Provide Engineering and Operational Assistance for the WWTP Operations Dear Mayor Smythe: wr BS) ----- End of picture text -----

Thank you for requesting this proposal for engineering services. We understand that the Village’s wastewater treatment plant (WWTP) is having serious operational difficulties and has not been able to treat the wastewater as needed to meet the requirements of its discharge limits for several months. Our approach is to re-start the plant’s biological process and we are prepared to provide direct day-to-day assistance in operating the WWTP to determine what is needed to achieve compliance with the discharge permit and address the odors at the site.

Our scope includes assisting the Village as follows:

  • ¢ Provide on-site hands-on operation of the plant to establish the existing conditions ¢ Provide a 4A chief wastewater operator and a 3A assistant wastewater operator ¢ Prepare the monthly DMR reports and any violation notices that are necessary

  • ¢ Meet or correspond with any DEC or DOH representative that is necessary ¢ Field check all the flows, influent and effluent wastewater parameters ¢ Take additional samples as need to identify if any unusual inhibitory chemical are influencing the plant ¢ We know that the plant receives septic waste and we will identify, purchase and try the typical chemicals used to address these wastes in wastewater treatment plants

  • ¢ The WWTP is an extended air activated sludge plant but it appears unable to grow and sustain sufficient activated sludge to provide treatment. We will re-seed the plant and operate the plant to identify why this is happening.

  • ¢ We will “figure out” how to operate this plant and train the Village staff to continue operations ¢ We will use our own TSS meter, DO meter, alkalizing and ammonia test kits and other equipment as needed to trouble shoot and operate the plant.

  • e Provide weekly updates to the Mayor on the progress of the work.

  • We bd Pravids op@amgsay MRM wa cernakiowy 4S) propose to conduct the work outlined herein for a monthly fixed fee of $4,000.00 per month and we expect these

  • services to last for 2 to 3 months. After this period, it is expected that the plant will operate “normally” and the Village will be responsible for operating the plant and we will be stop our “hands-on” role for operations.

We are prepared to start within 24 hours of being authorized to perform this work.

It is expected that the DPW Forman and his staff will be available and will provide assistance to operate the plant. This assistance will include taking wastewater samples, checking the WWTP on the weekend and on holidays, if

No substantive changes were made to the September 2025 Sewer Department Report.

## Village of Red Hook SEWER DEPARTMENT REPORT September 2025 We had an operational meeting on Sept. 10 & 25 where we reviewed sewer operations. H2O’s software platform, Waterly, is now up and running for the Village of Red Hook. This will enable the team to have ready access to all of the testing data in real time. We discussed a list of equipment and supplies needed for the Sewer plant. Karen will review and authorize these purchases. At the “old plant”, Plant 1B, a pump has been installed in the EQ tank to allow for better management of the flow. Now that the biology or “bugs” are growing well, there is a need to maintain the right amount which means sometimes an excess needs to be “wasted”. With the added pump in the EQ tank, that will allow for wasting to occur. The West side aeration tank is waiting for a valve replacement so that the return activated sludge can function on this side. This valve replacement is scheduled for the week of 9/29. The East side is currently handling all the flow. Some adjustment to the floats in the sand filter is needed. The new plant, Plant 1A, the plant is operating smoothly. It functions best when it has consistent, steady flow through the plant. Wasting of the biology or “bugs” needs some adjustment and the sand filter floats also need some adjustments. H2O did discover that our BOD testing, since June, has not been in compliance. The test required changes seasonally so from June to Oct, a different test is required. This change was made due to human error. H2O contacted DEC and has reported our non-compliance. Everything else has been in compliance. While the other test results would indicate that the BOD test should have been in compliance, there is not a calculation that can confirm that. There was a significant toilet leak in one of the apartment buildings on the sewer system. Fortunately the water meter for that building had been changed to a cell meter so the location was isolated quickly. All the extra water flowed into the system to the WWTP which caused the extra EQ to fill up. This reiterates the need for the expanded EQ tank capacity to allow for disruptions in the system. We reviewed the proposed alarm system from Vector and the team determined that we could set up our own system with notification via cell service that would function just as well and would be less expensive. Next steps to be discussed at our next meeting. We received no odor complaints that tied to the WWTP in the month of September. The last WWTP odor complaint we have received was in early May. Rural water is scheduled to meet with the Sewer team in mid-November to help the team begin developing an asset management plan.
