Phosphorous Removal and Excess Flow Improvements Project
Flagg Creek Water Reclamation District applied for and received a $4 million loan from the Illinois Environmental Protection Agency (IEPA) for the construction of the Phosphorus Removal and Excess Flow Improvements Project. The repayment of this low interest loan (1.56%) over 20 years allows the District to build this project without putting undue stress on its annual budget. The phosphorus removal component of the project is a new requirement of the IEPA in our wastewater treatment permit. The terms of our permit require that this work be completed by August 1, 2019. The project consists of the construction of two chemical tanks, three chemical dosing pumps, a phosphorus analyzer for chemical removal of phosphorus from the wastewater, conversion of the two clarifiers to dedicated phosphorus settling tanks, a backup submersible pump from these tanks, replacement of two grit washers, conversion of a third clarifier to dedicated excess flow treatment, and a new plant drain pipe.

Route 83 Lift Station Improvements
The Route 83 Lift Station, located in the middle of the street in Hinsdale, needed a new wet well access hatch
Old heavy double cast iron lid (that required two people to open) was replaced with a modern and easy to open/close single lid hatch with spring assist and ability to bolt lid shut
This installation required the new hatch to be cast offsite into a new precast concrete wet well top
The street was shut down on a Saturday to minimize traffic impact during removal of old concrete top and installation of new concrete top with new hatch

Flow meter with remote monitoring
New electrical distribution with added active filtering
Old diesel generator removed and replaced with modern and efficient natural gas fueled generator with portable generation connection capability added
New underground structure added to contain new valves and a pipe to ground surface that allows emergency pumping capability using a portable pump
