Protecting Infrastructure & Ensuring Reliable and Continuous Long Term Service:
The 5.5-mile system, originally installed in 1977, has experienced corrosion of the concrete pipe and structures (manholes and metering stations). The most recent video inspection by Great Lakes TV Seal, Inc. found extensive surface corrosion of the pipe, which threatens the longevity of the pipe. Without this project, more widespread damage will be done, requiring more extensive and costly renovation or replacement.
Meeting TMDL Discharge Limitations & Protecting the Environment:
HOVMSD has determined that additional treatment will be necessary to achieve compliance with its phosphorus and suspended solids Total Maximum Daily Load (TMDL) allocations. The District conducted a pilot study that validated its effluent would meet all requirements using chemically enhanced flocculation and disc filter effluent filtration technology. The effluent disc filters are being installed in an existing building and can provide filtration capacity to match the existing Biostyr maximum capacity of 26 MGD.
In order to protect our waters, the wastewater treatment process, as well as comply with State and Federal law, the Heart of the Valley Metropolitan Sewerage District has operated a state-approved Pretreatment Program since 1990.
