A Budget is a Tool - that provides resources to enable us to accomplish our objectives. “a means to an end” 3
What are our Objectives? Safe drinking water A reliable system of delivery Full cost recovery • Avoid deferring burden to future generations Quality of life • Protection of natural environment • Eliminate basement flooding/sewer backups Open up lands for growth & revenue opportunities 4

Extraneous Flow Reduction • Manhole Repairs • Town & Private Side Lateral Repairs • Weeping Tile Disconnections • Sump Pump Disconnections • Roof Leader Disconnections 18
Extraneous Flow Reduction Program Progress in Crescent Park Tools to Establish Effectiveness • Flows were monitored in 2004 and again in 2009 at the same location • Detailed analysis and comparison of these data were completed to draw conclusions on the effectiveness of the program • Comparison completed for dry weather conditions and for wet weather conditions 19
Dry Weather Flow Comparison • From 2004 to 2009, the average dry weather flow was reduced from 26L/s to 15L/s (42% reduction). More capacity is now available for wet weather extraneous flow. • Represents an annual reduction in flows being treated at the Anger Avenue of approximately 300,000 m 3 . • This reduction was achieved by reducing the amount of dry weather groundwater infiltration that enters the sanitary sewer system through foundation drains and cracks within lateral and street sanitary sewers. 20
Wet Weather Flow Comparison • For a total of seven rainfall events • Overall reduction in extraneous flow event volumes of 60% was achieved with repairs completed to date • Overall reduction in extraneous flow event peak flows of 55% was achieved with repairs completed to date. • Measured frequency of bypass events at the Dominion Road Pumping Station will be assessed through modelling • Difficult to assess using collected data due to variability of weather patterns 21
Key Drivers – Infrastructure/Capital Water Master Plan • Approved in 2009 • Per capital presentation optimal annual funding is $2.3 m • Current operating budget allocation to reserves $1.2 m Gap of $1.1 million 2011 budget recommends $50,000 increase in reserve allocation to fund gap. 22
Key Drivers – Infrastructure/Captital Wastewater Master Plan • Relying on previously approved version with updates from new draft • New version for April 2011 Approval • Per capital presentation optimal annual funding is $2.0 m • Current operating budget allocation to reserves $1.1 m Gap of $0.9 million 2011 budget recommends $50,000 increase in reserve allocation to fund gap. 23
Key Drivers - Infrastructure $4,773,002 capital budget for 2011 • 52% of total 2011 Capital request of $9.1 million • Excludes $150,000 Warren/Lewis Service Improvement as it requires $257,000 storm component to be approved with General Levy budget • 65% for Garrison Road Sanitary Sewers to support growth and environmental benefits 24
Garrison Rd Growth Benefit Approximately $10 million in residential and commercial Development Charges
Garrison Rd Environmental Benefit 26
Key Drivers – Financial Significant Regulatory Compliance PSAB compliant reporting O.Reg. 284/09-amortization not included in 2011 budget but long term strategy is in place. Reduce reliance on reserves funding jobs moved from capital budget to operating budget. O.Reg. 453/07 - Financial Sustainability Water License Financial Plan – CS-30-10 approved September 20, 2010 and filed with MAH Infrastructure reserve funding strategy moves toward capital asset full cost recovery. Continuation of 0.5% of revenues ($70,000) allocation to Rate Stabilization Reserve recommended for 2011 27
2011 Town Revenue and Expenses – 1.14% • Elimination of Regional grants for extraneous flows • R educed reliance on reserve funding for “pre - PSAB” capital projects offset with savings from bi-monthly meter reading • Debt charges for 2010 Crescent Pk water debt of $713,000 • Water Emergency Relief Fund (WERF) • launched 2008 with $15,000/yr.; for low income families to avoid interruption of services • Senior Utility Relief Fund (SURF) • launched in 2010 with $21,000; $100 account rebate for low income seniors 28
Distribution Cost Benchmarks Distribution cost per km of watermain WATER 2008* 2009 2010 2011 Town $6,485 $7,246 $7,257 $7,374 BMA Avg. $9,627 Town breaks per 100 km of watermain for 2008 5 BMA study average for 2008 8.9 Distribution cost per km of sanitary sewer WASTEWATER 2008* 2009 2010 2011 Town $7,215 $6,474 $5,963 $8,047 BMA Avg. $6,495 *Changes in 2009 PSAB reporting requirements have changed the method of reporting operating costs therefore 2008 is not consistent with 2009 onwards. 29
2011 Regional Treatment Costs – 1.47% • 58% of Town’s budget • Region’s draft budget (to be approved Feb17) • $18.9 m of Region’s 2011 Water & Wastewater Capital Budget is for TOFE projects • 53% of Sewer budget allocated to TOFE (Anger and CB WWTP) • No change in Region’s billing formula • Region is considering an additional 2% allocation to reserve but recommended for deferral until 2012. 30
2011 Supplementary Requests – 0.82% 1. Senior’s Utility Relief Fund (SURF) • Continuation of program requires sustainable operating budget funding rather than Water Infrastructure Reserves used 2010 • $21,000 at level of 2010 requirement 2. Infrastructure Reserves • long term strategy for full cost recovery as required by legislation. • $100,000 split $50,000 to each of water and sewer 31
