BACKGROUND
The GLWA Conveyance System consists of a network of sewers which collect and transfer wastewater to the major interceptors for flow management to the Water Resource Recovery Facility (WRRF). There are three major interceptors - Detroit River Interceptor (DRI), Northwest Interceptor (NWI), and North Interceptor East Arm (NIEA). The Northwest Interceptor (NWI) ranges in diameter from 4 feet to 13 feet.
A condition assessment of about 7.5 miles of this 15 miles long interceptor revealed two severe structural defects in it which were addressed as emergency repairs, both completed under CON-149 (Emergency Sewer Repairs Contract), to avoid a collapse.
GLWA's consultant, FK Engineering, under existing contract CS-168, completed a further assessment of the NWI from 8 Mile to Tireman and designed repairs for rehabilitation of the NWI from 8 Mile to Tireman. Contract No. 2102824 is for this rehabilitation
