D7.8 HYDRAULIC MODELING AND ASSESSMENT
D7.8.1 General
(a) During dry weather flow, sewage flows from Cockburn West and Cockburn East are directed by
the primary weir to the CS Lift Station and pumped to the Baltimore interceptor sewer. From
Baltimore district flows are pumped across the Red River to a gravity sewer flowing to the Mager CS
Lift Station. The Mager CS Lift Station then pumps to the south end interceptor system, which
flows by gravity to the SEWPCC for treatment.
(b) During wet weather, any flows that exceed the diversion capacity of the primary weir is
discharged into the Cockburn outfall, where it flows to the Red River by gravity.
(c) Under high river level conditions and when gravity discharge through the Cockburn CS outfall
is not possible, the excess flow is pumped by the Cockburn FPS to a separate outfall adjacent to
the CS outfall, where it will discharge by gravity to the Red River.
(d) The Sewer districts to be hydraulically analyzed shall include:
(i) Cockburn;
(ii) Cockburn West; and
