CSO 14 Separation

CSO 14 Separation Project


Project
The project, made up of two phases, will employ two different contractors that will work simultaneously beginning in the spring and cost a total of approximately $6 million. Phase I which includes a 1 million gallon underground storage tank, a 9mgd pumping station and High Dive Park amenities. Phase II includes underground piping through Hive Dive Park and total infrastructure rehabilitation on portions of Cassopolis, Crawford, Beardsley and Christiana streets. CSO 14 Phase II Before

The High Dive Park - CSO 14 project will utilize new technologies along with the standard type project construction to achieve its goal of reducing CSO overflows into the lagoons in High Dive Park. The 1 million gallon underground storage tank will use state of the art equipment to minimize cleaning, maintenance and energy costs. The deepest sewer lines along Cassopolis and Beardsley will not be removed, but instead will be lined with a cured in place resin liner which will reduce the amount of excavation and disruption - thus, a much quicker process overall.

Originally the City had planned to issue standard municipal bonds to fund this project, but in October the Indiana Finance Authority offered to provide very low interest rate loans saving the City millions of dollars in interest costs over the 20 year term. As a condition of the offer the interest savings will be used to fund the cleanup of two Brownfield sites in Elkhart.

This project and the CSO 4 & 30 sewer separation project that began in October are the first two elements of the City's CSO Long Term Control Plan. The High Dive Park project will eliminate 4.7 million gallons of untreated wastewater over the course of 14 potential sewer overflow events per year. The CSO 4 & 30 project will eliminate 6.7 million gallons of untreated wastewater during 46 potential overflows a year.
