In recent years, Canadian municipalities have realized that the price we pay for water and wastewater services must rise. We’ve needed to move towards sustainable systems not just from an environmental perspective, but also to meet social and financial sustainability requirements. Historically, water and wastewater prices have not reflected the true cost of providing those services. Starting in the mid-2000s, major municipalities have increased their water and wastewater rates with yearly increases well above inflation (as much as 8-10 per cent above CPI).

Such increases have understandably caused concern about the “affordability” of the prices which residents are charged for water and wastewater services. A recent Association of Municipalities of Ontario (AMO) publication entitled Towards Full Cost Recovery: Best Practices in Cost Recovery for Municipal Water and Wastewater Services raised this issue, but the purpose of this note is not to argue that affordability should be ignored in rate design. Rather, we argue that there is a need to ensure that all goals are adequately considered and balanced when examining rate proposals and that discussions regarding rate design are based on the best available evidence.

The condition of our water and wastewater infrastructure

The September 2012 Canadian Infrastructure Report Card (seeThe State of Our Water Assets,” rated Canada’s water and wastewater infrastructure as “good” overall. However, beyond these overall ratings, 40 per cent and 30 per cent of wastewater facilities and collection systems, respectively, are rated as being in “fair” to “very poor” condition. Fourteen per cent and 15 per cent of water facilities and distribution systems were respectively “fair” to “very poor,” too.

The report gave the main reason as past reductions of investment in infrastructure. Under current investment levels and unless asset management practices are improved, it says, the condition of our water and wastewater systems will continue to deteriorate and will result in ever-increasing costs to maintain the same service levels. In Ontario, the Watertight report (2005) estimated that the water and wastewater sector in that province alone required an investment of $25 billion for asset renewal (excluding investment required because of growth) over 15 years.

These reports and others have drawn attention to the issue. Other initiatives and considerations, as noted below, will also push municipalities to eventually adopt full cost pricing for their water and wastewater services. If not, those services will not be sustainable; ultimately, their reliability and safety will decrease, and accordingly the public’s confidence in them. It is also important to note that reductions in reliability will not impact all households equally. Higher income households are able to insulate themselves from the potential consequences of underfunding (for example, by purchasing point-of-use water disinfection systems). Conversely, lower income households are likely to be impacted more harshly by reductions in system reliability. Other pressures and considerations which emphasize the need to adopt full–cost pricing:

  • The degree to which the federal and provincial governments can be expected to fund municipal water and wastewater infrastructure in the future is limited due to their own budgetary and debt constraints.
  • Changes in accounting rules required by the Public Service Accounting Board (PSAB) which, for the first time, required municipalities to show the depreciation of their tangible capital assets, such as water and wastewater systems, on their books.
  • Direction and regulations from senior levels of government requiring municipalities to manage their water and wastewater systems in a sustainable manner. Example: the requirements for sustainability plans under Ontario’s Water Opportunities Act.

These factors will drive municipalities to charge a price for delivering water and wastewater services including water source protection, depreciation of infrastructure assets as they age, and eventually decommissioning and replacement of assets as they reach the end of their serviceable life. An important question remains. Will these anticipated rate increases disproportionately impact lower income households?

Spending on water

According to Statistics Canada, the average amount spent per household on “water, fuel and electricity” was $2,204, or 3.1 per cent of total expenditures. Furthermore, according to Environment Canada data, the amount spent per household for an “average” consumption level of water (25 cubic metres per month) was approximately $53 per month. Thus, the approximate amount for water spent by the average household was 0.9 per cent of total expenditures—below the standards set by international agencies as their measures of “affordable” water supplies (De Los Ángeles García-Valiñas et al., 2010). What of lower-income households? Statistics Canada data show that the share of income going to spending on water and sewerage services increases as income declines.

Water and sewerage spending as % of total household income Total household income range
4.3% Under $20,000
1.4% $20,000-40,000
0.9% $40,000-60,000
0.7% $60,000-80,000
0.6% $80,000-100,000
0.4% Over $100,000

Options for incorporating affordability concerns

The table shows that there is a potential for water rate increases to disproportionately harm low-income households. What is important to recognize, however, is that this need not be so. There are a variety of policy options available to ameliorate the impacts of rate reform. These options include the following (S. Renzetti, 2009):

  • Placing more emphasis on revenue generation through volumetric charges and away from regressive connection charges.
  • Implementing summer surcharges that would impact primarily households with large lawns and pools.
  • Identify the proportion of water supply costs arising from fire-protection services and basing these on property values rather than water consumption levels.
  • Implement increasing block rate prices and employ any surpluses generated to subsidize consumption by low-income households.

There is no doubt that an increase in cost in every service or commodity, whether it is water and wastewater, hydro, gas, transportation, or food, can be a significant challenge and hardship for households that have the lowest incomes. Appropriate measures must put in place to safeguard these households. However, we put forward the position that any likely increase in water or wastewater prices required to reflect the full cost of providing those services is well within the affordability limits of most Canadian households. Furthermore, policy measures can be implemented to temper the impacts of rate increases for those households at risk. What is most important to recognize is that the goal of sustainable water systems and the protection of vulnerable households are not incompatible.
