“PUBLIC WORKS DEPARTMENT UPDATE: March 27, 2026 birds. Even the smallest green spaces, like flower boxes and curb strips, can be part of a pathway. There is no cost to be part of the Pollinator Pathway. Additionally, it shows the city in a very positive environmentally conscious light. WATER The city has requested Categorical Exclusion from further environmental review for our upcoming work on the Rink Creek Reservoir and the Knowlton Heights and Oerding finished water tanks. This is the portion of the Phase I Water System Improvements that has been funded through a loan/forgivable-loan package from the Safe Drinking Water Revolving Loan Fund. Engineers at the Dyer are preparing the final plans and documents for plan review by the Oregon Health Authority. We expect to begin advertising these projects for bid this spring. The city was not awarded assistance through the Community Development Block Grant Program for the other portion of the Phase I Water System Improvements (replacement of the river pump force main and numerous repairs and upgrades at the water treatment plant). Engineering for these projects, fully funded through CDBG, has been completed and approved by OHA. We will apply for CDBG funding again for the bidding and construction phases of these projects at the next available opportunity. Our lighting upgrade contracts with the Energy Trust of Oregon have been finalized, and we look forward to getting all the lighting upgraded at the water and sewer plants and the Public Works shop sometime in April, free of charge! SEWER During the Council Goal Setting Session on March 16 , I was asked about the costs for the addition of a second sludge press at the wastewater treatment plant. The figure I provided was representative of the cost of a second press similar to our existing one, however the engineer’s recommended project calls for a larger press and carries numerous costs in addition to the press itself, and I wanted to provide better information regarding the anticipated financial needs of the wastewater system. The engineer’s estimate for the proposed improvements to the Biosolids Dewatering System (an additional, larger sludge press) is approximately $1.14 million. Collection system improvements to reduce infiltration and inflow into the wastewater system were also discussed at the Goals Setting session. While we have remained in compliance with our NPDES permit since October, thanks largely to an unusually dry winter, we typically ha”

“Issue: The following issues will need to be maintained and improved to ensure compliance with drinking water rules and safety standards: • Reinforcement of the sedimentation basin exterior wall (considered as a major structural flaw). • Construction of a FRP baffle wall separating the flocculation chamber and settling basin. • Replacement of a 12-inch raw water line with a 14-inch line due to leakage and other high maintenance issues. • New improvements needed for the Oerding pump station: a 200 gpm duplex booster pump, a pressure reducing vault (PRV) station and the installment of a solar powered active mixier in the Oerding Tank. • The river pump station and the 14-inch raw water line are needed to ensure water availability during the summer months, when the reservoir is not able to meet the water demand. • Treatment nearing the end of its useful life: replace chemical feed pumps, onsite chlorine generation system, control systems and settling basing sediment removal system. Project: It is an improvement project to maintain the quality of the system, increase fire flow, reduce unaccounted water losses, extend the life of the existing tanks, and install needed telemetry for the entire system.”
