Work in Progress - Sewerage District

Work on the 80 million dollar 5 year program will be completed in the Spring of
1975. The purpose of this program has been to provide a minimum of primary
treatment for all sewage discharges from the Greater Vancouver area. It also
included the elimination of continuous overflows of sanitary sewage to the Burrard
Inlet. This program required the construction of approximately 78 miles of pipe~
lines, two dozen pumping stations, two treatment plants and improvements to the
two existing treatment plants. ,

In the Fraser Sewerage Area the Annacis Island Sewage Treatment Plant being con~ |
structed by Cana Construction is now 60% complete. Tistrict Forces have completed
10% of the 17,000 feet of South Surrey Interceptor sewer which passes through

Surrey and Delta along the northerly boundary of the Burns Bog. This sewer comprises
14,500 lineal feet of cast-in-place box with inside dimensions 5 feet by 6 feet and
2,500 feet of twin 68 inch diameter precast pipes. District Forces have commenced
the construction of the Port Coquitlam Forcemain which comprises 8,300 feet of 36
inch diameter concrete and steel pipe. This pipeline will connect the Port Coquitiam
Pumping Station to the Coquitlam Interceptor adjacent to the Essendale Hospital.

Bent Construction who have contracted to construct the Port Coquitlam Pumping Station
have commenced dewatering the site to prepare for excavation. Tenders for the Con-
struction of the two interceptors which run north to intercept to Port Coquitlam Lagoon
and south to pick up the Mary Hill Area will be called later this month.
