Background/Project Description

The 2012 Wastewater Utilities Master Plan and Capital Improvements Program recommend the construction of the Wakarusa Wastewater Treatment Plant (WWTP) and Conveyance Corridor facilities to be online in 2018.

Project Details

Project UT1304 consists of multiple design and construction contracts. UT1304 Contract 3 (PW1405) includes road improvements for E1600 Rd (O’Connell Rd) and N1175 Rd (41^st Street) to provide access to the Wakarusa WWTP. E1600 Rd will be the primary access to the site from N1100 Rd. It will be improved to an Alternative City Street Construction Standard designed to accommodate the anticipated truck traffic during construction and operation of the WWTP. The alternative street standard allows for the use of an open ditch vs. a curb and gutter road section. Construction of the pavement section on E1600 will be phased such that a base section is built to handle construction traffic and a final asphalt or concrete surface will be added to E1600 Rd upon completion of the WWTP construction. N1175 Rd will be the secondary access to the site and will be improved to a gravel road with a chip & seal surface. Improvements include relocations of the RWD4 and Baldwin waterlines along E1600 Rd south of the metering station. Contract 3 also includes placement of fill at the Wakarusa WWTP site to allow for consolidation to take place prior to facility construction beginning in 2015.
