SE3 served as the prime engineer with the Kansas City Water Services Department (KCWSD) on this portion of their Water Main Replacement Program for Fiscal Year 2018. This is the third water main design that SE3 primed and completed for the KCWSD. This water main replacement project included areas within the downtown Kansas City Loop and included various complexities such as active steam lines and crowded existing utilities within the corridors. Alignment studies were conducted to avoid the existing infrastructure and complete construction documents were prepared for the replacement of existing water mains and transmission mains.
One location included an existing 160 kV electrical line that needed to be crossed by the proposed water main replacement. Traditional trenching construction methods could not be used around this high voltage electrical line. The SE3 design provided for the installation of high-pressure polyethylene pipe via horizontal/vertical directional boring.
