Waste Water Department

Waste Water Department

Lincoln Sewer Plant Built in 1930’s.  The system was designed for Combined Sewer –Sanitary and Storm water.  Plant will see anywhere from 2 million gal/day to 10 million gal/day of normal flow. Storm flow can treat up to 33.5 million gal/day.


Federal EPA’s CSO Control Policy of 1994 set parameters to limit Combined Sewer Overflows during wet weather


2013 – IL EPA required to develop plan to be in compliance. Crawford, Murphy, and Tilly (CMT) was selected after Request For Qualifications Process in fall of 2013 to draft the Long Term Control Plan (LTCP).  We submitted LTCP in 2015, after 2 years of development, to Illinois EPA.  Plan was approved by IL EPA in October 2016 to complete within a 5 year schedule. It is primarily focused on treating combined sewage during large rains. Project is not replacing/rehabbing aging sewer mains in the City.


Two Projects:

  • Union Street Pump Station Rehab - Larger Pumping Capacity- Design currently underway, Completion in Late 2019-Early 2020
  • Wastewater Storm Water Treatment Upgrades- Increase Volume Treated and Improve Water Quality at Waste Treatment Plant only- Not in design phase yet, Completion expected 2021


Using IL EPA State Revolving Loan Fund (SRF Program) as funding mechanism:
- 20 year loan at 1.75% interest, currently- Expected to be around 1.875% at time of closing on Union Street Project


Estimated costs - $20 to $22 million for both projects. Approximate annual payments between $1.2M & $1.4M
