Peosta Wastewater Collection System Improvements

The City of Peosta has experienced both tremendous population growth and commercial development in the past twenty years. To meet future demand, the City is expanding its sewer capacity in two areas of the City in anticipation of further growth.

IIW is designing nearly 9000 LF of sanitary sewer piping. The project consists of two phases.

The first phase, Parkview, is to replace an existing, smaller diameter sewer that serves the southeast part of the community with 3,900 LF of 8- and 12-inch piping. Growth in that part of the community is what’s driving that portion of the project.

The second phase of the project, Royal Oaks, includes installation of an interceptor sewer on the northwest side of the community to increase capacity in an area that has seen substantial growth over the past five years. This consisted of 4,900 LF of 12- and 18-inch sanitary sewer and 1,000 LF of 6-inch force main. Construction is slated to begin this fall, with completion in the spring of 2017.

The projects were first identified as part of a wastewater collection and treatment study update that IIW completed in 2013 for a wastewater treatment facility study that was originally completed in 2007. The 2013 update was commissioned due to substantial growth in the community—only six years into the 20 year planning period.
