Manitoba Water Use Efficiency Program
Municipal Actions to Consider
On May 31, 1994, the Canadian Council of Ministers of the
Environment (CCME) approved The National Action Plan to Encourage
Municipal Water Use Efficiency. The goal of the plan is "to
achieve more efficient use of water in Canadian municipalities in
order to save money and energy, delay or reduce expansion of existing
water and wastewater systems, and conserve water".
Manitoba Environment is initiating a Water Use Efficiency
Program based on the two main elements of the CCME's action plan.
The first element emphasizes government leadership by encouraging
reduction of water use in government's own facilities, advocating
adoption of water efficient policies, regulations and codes, promoting
public awareness of benefits of water use efficiency, and encouraging
acceptance and use of water efficient products. The second element
urges assisting actions at the municipal level that increase water
efficiency. Manitoba's plan reflects these priorities.
Manitoba's program is built on activities that address various
aspects of the six objectives identified in CCME's plan:
- Strengthening partnerships with municipal and local governments,
and other agencies of the provincial government;
- Identifying existing barriers to efficient water use, and
developing plans to overcome those barriers;
- Changing existing plumbing codes to encourage water efficient
appliances and systems, and reviewing the impact of other
legislation on water use;
- Developing and distributing public education materials;
- Retrofitting key government buildings to demonstrate benefits of
efficient water use; and
- Defining water use efficiency specifications for new
construction and permanent renovations of public buildings.
The need for efficient use of municipal water in Manitoba is not
obvious. Manitoba is blessed with an abundant amount of surface and
groundwater in its inland lakes, rivers, and aquifers. However, the
amount of water available for municipal use in Manitoba is
diminishing. Water sources available to communities have sometimes
become contaminated due to results of natural or human processes.
Consequently, suitable water sources are becoming less common.
Treatment is becoming essential. Treatment and accessibility are
therefore becoming expensive factors in municipal water supply
decisions. In addition, the costs of providing water and wastewater
treatment services to Manitobans are steadily increasing.
Consumption rates, both at work and at home, are very high in
Canada.
In Europe and Australia, water conservation in industry is
essential to remain competitive. Environment Canada reports that water
in Sweden costs over twice as much and in Australia over four times as
much as in Canada.
In the home each day, each of us uses about 340 litres of water.
Compare that to average European water consumption at just 140 litres
per day. During the summer, our household water use can increase by
50% or more.
Reducing the demand for this life sustaining resource begins with
each of us.
Municipal Expenditures and Water Use
The expenses associated with a steadily increasing need for
municipal water are numerous. The infrastructure that brings water
from the water source must be built and maintained. Large quantities
of energy are used to pump the water from the water source, through
the system to the user. Similarly, wastewater must be collected and
transported to the sewage treatment plant before being released back
to the environment. Treatment technologies required to produce high
quality water that is in compliance with the Guidelines for
Canadian Drinking Water Quality can also use costly labour and
chemicals. Handling the resulting wastewater safely and effectively
also requires expensive infrastructure, ongoing labour and chemical
costs, and monitoring programs.
Municipal Benefits from Reduced Water Use
In addition to exercising better stewardship of a precious
resource, water use efficiency produces economic benefits by helping
to:
- Reduce or defer municipal water treatment or wastewater
treatment plant upgrades or expansions.
- Extend life of current treatment plants.
- Allow more users to use existing treatment plants.
- Defer need for additional water sources.
Possible Municipal Actions
The following options should be considered when designing a
municipal water use efficiency plan:
- Water audit: Investigation of municipal water use and
waste.
- Target-setting: Determine water supply and treatment
issues in your particular community. Set quantity reduction and
time frame targets based on obtainable goals and your community's
needs.
- Water metering and pricing: Install meters for every
customer; (awareness of water use enabled by metering can reduce
domestic water consumption by 10% to 50%); adjust rate structure
to meet your community's water service objectives.
- Reducing municipal water system leakage: If the water
audit reveals unaccountable water loss, initiate a leak detection
program for the infrastructure of the community. (Losses as high
as 35% of a city's water output have been detected.)
- Leading by example: Investigate the feasibility of
retrofitting buildings owned, rented, or operated by the
municipality;.
- Awareness and education: Promote water issues and discuss
solutions with the citizens of your community. Outline specific
benefits for domestic, commercial, and industrial sectors. Educate
consumers about the actual charges for the various components of
their water delivery system, and savings that would be achieved
with water efficient devices.
- Customer incentives: Retrofit programs, or installation
of water saving fixtures can be facilitated by a grant or rebate
program.
- Guidelines and by-laws: Issue guide-lines or by-laws
which promote efficient water use.
- Review administrative policies: Regulate water pressure
in the distribution system. Pressure at 350 kPa (50 psi) will
reduce leaking around valves and linkages, and may reduce
consumption in the same way as low flow faucets and shower heads.
Summary
Clean water is a finite resource, even in Manitoba. Treating
municipal water, and wastewater to an acceptable level requires
sizable infrastructure and operating expenditures. Encourage modest
consumption rates, both at home and at work. Using water efficiently
is a key to solving water related municipal supply challenges..
