Master planning, reinvestment planning and financial planning: The combination that worked for the District of Squamish

Description:Master planning, reinvestment planning and financial planning: the combination that worked for the District of Squamish. Presenter: David Roulston, P.Eng., District of Squamish. Clive Leung, P.Eng., Opus DaytonKnight Consultants, North Vancouver, BC. The District of Squamish’s Asset Management Plan has estimated that Asbestos Cement (AC) watermains in the District are expected to have 10 years of remaining service life and compose of 70% of its water system. A significant infrastructure spending gap was identified. The District retained Opus DaytonKnight to prepare a Water Master Plan with the following primary objectives: (1) Develop a comprehensive capital expenditure budget that addresses the needs of new residents and the infrastructure gap, (2) Review utility finances and develop sustainable funding including updating an outdated water rate structure, (3) Prepare a water conservation program, and (4) Recommend a water metering strategy. A Risk Assessment that sought to address the initial infrastructure gap was carried out. Opus DaytonKnight reviewed the criticality of replacement of AC watermains which moved beyond theoretical age based assessments to real and tangible condition and performance-risk based assessments of reinvestment need. This was achieved through inclusion of break history records and balanced responses to consequences of asset failure. A field testing program and revisions to asset repair logging were also recommended to improve estimates of remaining service lives of these assets and future revisions of the risk assessment approach. A 25-year Capital Plan summarized capital infrastructure projects required through growth and reinvestments needed for AC watermain replacements. A Financial Plan concurrently prepared considered borrowing capacities and debt servicing limits of the utility to inform the District of required water rate increases needed to finance the water utility going forward for the next 25 years.
