III. DESCRIPTION/BACKGROUND
In 2015 and 2016, City maintenance workers conducted video inspections of City wastewater and stormwater pipes. The video inspections revealed that many existing wastewater and stormwater lines were badly deteriorated and in need of rehabilitation. This project successfully rehabilitated over 3/4-mile of wastewater pipe and over 1,200 lineal feet of stormwater pipe using a cured-in place pipe trenchless technology. Existing wastewater and stormwater pipes have been restored with a new interior hardened liner that will significantly increases pipe life span.
The wastewater fund was under budget in the amount of $42,699, and the stormwater fund was exceeded in the amount of $60,992. The higher stormwater cost was due primarily to a construction change order for using a higher grade of cured in place pipe material that was less harmful to the stormwater environment.
