DISCUSSION
Replacement of water distribution pipes and related facilities is an ongoing program to replace
aging, substandard and deteriorating infrastructure. This program has three objectives:
1) Ensure reliable water services
2) Reduce the need for emergency repairs
3) Enhance available fire flows
Based on priorities set by the Utilities Department, certain waterlines have been selected for
replacement as shown on Attachment 1. The assumed useful life expectancy of water lines is 50
years. The waterlines proposed for replacement with this project were originally installed in
1940s, 50s and early 60s. Presently the water mains on this project are substandard, deteriorated
and leaking. Their replacement will eliminate capacity issues and improve water flow for fire
protection. Replacing these waterlines will result in lower costs and reduced customer impacts
that would otherwise be associated with emergency repairs and provide more time for preventive
maintenance, which prolongs the expected service life of Water Distribution facilities and
equipment.
CONCURRENCES
The Community Development Department has granted a Notice of Exemption since minimal
environmental impacts are anticipated.
