Overview

The Clear Creek Conservancy District is a special district unit of government, which operates a wastewater treatment plant for 6 subdivisions of Heritage Lake. The plant has reached its capacity of 0.4 MGD and is over capacity when wet. In 2019, average daily flow was the highest on record at 475,000 GPD which triggered a warning letter from IDEM. CCCD also received Sewer Ban Early Warning letters in November 2020 and April 2021. While efforts have been made to control Inflow/Infiltration by completing manhole inspections, repairing sewer mains and continuing I/I inspections for every house sold, additional treatment capacity is necessary to comply with IDEM requirements and meet increased demand. The proposed project starting Nov 2022 will increase treatment capacity from 0.4 MGD to 0.9 MGD by May 2024. Funding contributions are made by Putnam County, Clear Creek Conservancy District and 2023 AV Improvement amounts. This will allow capacity to meet needs for current and projected flow and waste loadings. The project includes headworks upgrades, a third oxidation ditch, an additional clarifier, replacement of existing chlorine disinfection with UV disinfection, additional sludge management piping, upgraded lift station, and outfall sewer. The preliminary effluent limits are significantly lower than the current limits of the existing plant for CBOD5 and TSS. Current number of connections are 1,590 w/ 26 pending where the updated plant will be ~2,200 connections.
