Illinois-based water facility under multimillion dollar renovation and expansion project

Jan. 29, 2015

ST. LOUIS — The approximately $7.96 million renovation and expansion project will bring the water treatment plant up to EPA regulatory compliance standards and increase the facility’s water storage capacity from 1.15 million gallons to 1.65 million gallons.

ST. LOUIS — Contegra Construction Co. announced it plans to complete the renovation and expansion of a water treatment plant serving Roxana, Illinois, this fall, according to a press release.

The around $7.96 million renovation and expansion project will bring the plant up to EPA regulatory compliance standards and will increase the facility’s water storage capacity from 1.15 million gallons to 1.65 million gallons, stated the release.

The release reported that the plant, built in 1977, has not been “comprehensively upgraded” in more than 20 years, and Contegra, in pace with “strategic, sequential demolition,” is installing a new forced draft aerator, water filters, a hydrated lime line-feed system, modifying the flow path of process water to existing clarifiers and is also “erecting a new chemical feed building and a 9,600-square-foot addition to the existing filter building.”

The release continued that a 750,000-gallon ground storage tank, a structure hosting clarifiers and an elevated, 300,000-gallon storage tank are being repainted.

“The new equipment and buildings require extensive SCADA (Supervisory Control and Data Acquisition) communication [systems], electrical and above- and below-ground piping upgrades,” said Contegra Project Manager Joe Koenig. “We’re working with pipe ranging in diameter from one-half inch to 24 inches.”

The facility remains "fully operational” during the expansion and renovation project, noted the release.
