Corunna council approves manhole and valve maintenance actions for wastewater and hydrants
Summary
Council approved ordering another load of slag for a wastewater manhole and authorized a recurring valve-servicing program for hydrant auxiliary/main valves after staff described groundwater infiltration, diffuser options and previous maintenance challenges.
The Corunna Town Council approved a set of maintenance steps to protect wastewater infrastructure and improve hydrant flushing. Staff reported a non-watertight manhole at the lagoon master meter that allows groundwater into the sump; council voted to order another load of slag (the same size as a prior 22-ton delivery was referenced) to improve the manhole casing and access.
Separately, staff proposed a recurring valve-maintenance program to exercise and service auxiliary hydrant valves and mainline valves that have not been turned in many years. Council members discussed scheduling hourly work (one proposal suggested five hours per month for valve-turning tied to meter-reading work) and agreed to begin the program; the motion to begin valve turning and service was approved by voice vote.
Staff described procedures and expected benefits: use of a John Deere tractor to place materials; building a simple diffuser to reduce road runoff during hydrant flushing; using riser rings to raise buried valve boxes and cleaning/operating valves by opening and closing them multiple times to free packing. The council also noted the town has been conducting annual hydrant flushing and that this valves program supplements that work.
The meeting transcript records these decisions by voice vote; no financial appropriation detail or vendor contracts were discussed during the motions. Staff committed to schedule the work and to coordinate where slag will be deposited and spread.
