Asset Management Plan Roads, Bridges and Structural Culverts, Water Distribution, Sanitary Collection, Water and Sewage Treatment Plants Prepared for: The Township of South Stormont 2 Mille Roches Road, P.O. Box 84 Long Sault, ON K0C 1P0 Prepared by: Phil Whelan, P.Eng. McIntosh Perry Consulting Engineers Ltd. 115 Walgreen Road Carp, ON K0A 1L0 December 11, 2013 Executive Summary The Township of South Stormont recognizes that in order to sustain services for its residents and for the competitiveness of its businesses, agriculture and industry, it must manage the Township’s assets cost effectively. McIntosh Perry and Allan Chartered Accountants were commissioned by the Township to develop the Asset Management Plans for the Road Network, Bridges and Structural Culverts, Water Distribution System, Sanitary Sewer Collection System, as well as Sewage and Water Treatment Plants. The findings for individual infrastructure varied, as follows: The Road Network requires additional spending to avoid network deterioration and optimize its overall condition rating (Section 3.1). Significant spending has been done to replace the aging Bridge infrastructure, which is reflected in the average bridge age of 24 years. The Structural Culverts are slightly older with an average age of 29 years. Of note here is that during the next 30 years, a significant number of culverts will be coming up for renewal (Section 3.2). The Township’s Water Distribution System is holding strong, as an analysis of the age distribution and average remaining service life of the Township’s watermains shows that, although a portion of the system is in the later stages of its expected service life, none of the watermains will reach the end of their expected service life within the time forecasted by this report (Section 3.3). Sanitary Sewer Collection Systems present in Ingleside and Long Sault carry an overall structural condition rating as “Good” (Section 3.4). The plan defines the average rating for Water and Sewage as “Good” while the overall physical condition (replacement-cost weighted) of South Stormont’s Water and Sewage Treatment infrastructure is “Average”. However, at this time, the Township has yet to develop levels of service for its water and wastewater treatment plants. As an initial step, it is recommended that the Township adopt approved plant capacity as an assessment criterion (Section 3.5). The Township of South Stormont’s overall plan takes a long-view perspective which focuses on timely maintenance and rehabilitation to save money in the long term. Not only does the plan outline infrastructure sustainability, but it provides strategies on how to finance the operation, maintenance, renewal and expansion of the system, taking into account asset preservation. It is important to note that the overall Asset Management Strategy (Section 4.0) states the biggest risk to the Township is inadequate spending. The consequences of underfunding include the deterioration of assets and service levels. It is recommended that the Township explore a variety of procurement methods to ensure the most economical allocation of the Township’s resources (Section 4.6). In addition, the plan suggests strategies to help mitigate some of the spending shortfall, including adoption of a 10-Year Capital Plan for Road Reconstruction and completing additional work included in the report as funds become available.
