Hiawatha sewer study approved
12/18/2019

(KNZA)--The Hiawatha City Commission has approved a flow study of the city's sewer system.

The Commission Monday evening voted to enter into an agreement with the engineering firm Olsson Associates to conduct the study at a cost of $309,177, contingent upon funding.

The Commission voted to apply to the Kansas Department of Health and Environment for temporary funding through the State Revolving Loan Fund to pay for the cost of the study. The current interest rate is 1.66 percent.

Despite the completion of previous sewer projects, City Adminstrator Mike Nichols says there are still parts of the city's sewer collection system that experience high amounts of inflow and infiltration during wet weather events. Nichols said the study is the first step is figuring out where the problems are in the system.

Engineer Mark Bachamp with Olsson Associates said the study will be conducted in the spring of 2020. As part of the study, he said seven electronic flow meters will be installed and two rainfall recorders to collect data over a 60-day period.

In addition, Bachamp said they will evaluate the city's six major lift stations to determine their current pumping capacity, operational issues and improvement options.

A preliminary engineering report is to be submitted in July.
