Saddle Creek Retention Treatment Basin Project


Construction anticipated to begin in 2017.

Project Description

The proposed Retention Treatment Basin (RTB) facility will provide treatment of combined sewer overflows prior to being released into the Little Papillion Creek. This project began planning and design activities in April of 2011 and is proposed to be constructed at 64th and Dupont Streets in Omaha. The RTB will be an underground structure where combined sewage is held during wet weather events and “treated” before being pumped into the existing sanitary sewer system for conveyance to the Papillion Creek Wastewater Treatment Plant where it will receive further treatment. Above ground improvements include a building to house controls, equipment, and chemicals, and a pump station building housing dewatering pumps and associated controls. Odor control features will be installed to eliminate the risk of odors being released to the surrounding area. The site will include fencing and lighting for security purposes. Chemical deliveries will occur regularly, but are not expected outside of typical business hours.

Conceptual design of the RTB began in early December of 2011. After the initial bidding process, the City determined the project needed further evaluation. A firm was hired to perform a value engineering process to identify design and construction savings. The recommendations are expected by fall of 2016. 

The Saddle Creek Basin area is sensitive to issues involving heavy stormwater events.  In addition, the area where the RTB will be built will be near new developments including new facilities being constructed by the University of Nebraska Omaha.
