Authority Manager Zarencik and Business Manager Shanna Dearing briefed the board on operations and maintenance issues at the Authority’s treatment plants and pump stations.
Zarencik said the search for a wastewater operator is ongoing and staff received a new resume for consideration. He reported the new motor for the belt filter press has arrived and a sludge-holding-tank blower has also been received; he said a bushing and pulley are pending to complete installation.
On equipment maintenance, Zarencik reported a recent vendor training and relayed the pump manufacturer’s recommendation to change oil after one year of service for specific pumps. He highlighted recurring problems at Millers Run: one pump was tripping an overload relay on start-up and operators found a small towel obstructing a flow-equalization pump (they removed it and the pump returned to service). He recommended evaluating the Cherrybrook equalization tank as a phased capital project to address deteriorated aeration and rag-catching issues.
For ultraviolet disinfection, staff reported repeated failures of the UVI sensor at Lawrence (Bank A) and said they are working with Trojan (the UV-system manufacturer) to obtain replacement sensors and diagnose the premature failures.
Business Manager Dearing reported a July 13 debt service payment of $240,115.43 for the Series 2017 bonds and said a certificate of deposit (CD00-13018987) matured; the board approved renewing the CD at a 4.11% interest rate (yield 4.25%) for one year.
Manager Zarencik said he obtained a $3,019 price on a replacement blower previously discussed and that he would seek clarification on unusually high vendor quotes for certain generator heater-block and battery items before proceeding.
The board asked staff to gather photos, cost estimates and grant possibilities to scope a phased rehabilitation project at Cherrybrook and to continue diagnostics on the tripping pump and UV sensor failures.
