seymour source water by removing turbidity and micro-organisms, and by reducing the amount of chlorine required to maintain water quality. following completion of the twin tunnels project in late 2013, capilano source water will also be filtered at the same plant and distributed by regional water mains. in summer, when water demand peaks, there are region-wide restrictions on lawn sprinkling to ensure that water supplies are adequate for more important uses, such as drinking water and fighting fires. in 2008 metro vancouver launched a campaign inviting the region's residents to make a "tap water pledge" to drink tap water in refillable bottles instead of buying single-use plastic water bottles, with the goal to reduce sales of bottled water by 20 per cent by 2010. in 2011, 85 per cent majority of residents polled in the region said they primarily drink metro vancouver tap water instead of buying bottled water. the region's waste water is treated in one of five waste water treatment plants operated by metro vancouver, two of which use primary treatment and the remaining three use secondary treatment. water use residential consumers in canada used 343 litres per person per day, or roughly twice as much per person as in other industrialized countries, with the exception of the united states and australia. according to one source water use in montreal, where there is little metering, is particularly high at 1,287 liter per person per day in 1999. according to the environment canada, the following sectors account for the following shares of municipal water use: 52% residential users 19% commercial users 16% industrial users 13% leakage. however, a different part of the same web site of environment canada states that leakage losses are actually much higher at "up to 30%". standards the guidelines for canadian drinking water quality of 1968 set guidelines for drinking water quality standards in canada, developed by health canada with the provincial and territorial governments and setting out the maximum acceptable concentrations of these substances in drinking water. the drinking water guidelines are designed to protect the health of the most vulnerable members of society, such as children and the elderly. the guidelines set out the basic parameters that every water system should strive to achieve in order to provide the cleanest, safest and most reliable drinking water possible. three canadian provinces require all public water supplies to be disinfected, while other provinces require disinfection only for surface water supplies. the standards for used water or wastewater quality came into effect july 18, 2012. responsibility for water supply and sanitation while the responsibility for the provision of water supply and sanitation services in canada lies with municipalities, the provincial governments and the federal government also have important responsibilities related to the setting of standards, research, economic regulation and water resources management. as all levels of government hold key policy and regulatory levers which apply to water and sanitation, a central challenge is to ensure that these levers are developed and used collaboratively. the canadian council of ministers of the environment - which consists of the 14 environment ministers from the federal, provincial and territorial governments - plays an important role in the development of national strategies, norms and guidelines for water supply and sanitation. the need and the difficulty to collaborate between different levels of government is apparent in the discussion of a proposed national municipal wastewater effluents strategy. according to the canadian water and waste water association "canada faces a variety of provincial and territorial approaches (to wastewater and biosolids) that are not consistent with federal legislation, and we have no structure to have a rational science-based discussion of the policies and regulatory requirements that would enable us to identify and promote the beneficial use of these environmental resources."t. duncan ellison, executive director, canadian water and wastewater association provinces and territories the governing of drinking water and sanitation in canada falls under provincial/territorial jurisdiction. the provinces and territories are responsible for developing and enforcing all legislation pertaining to municipal and public water supplies including their construction and operation. each province also has a public utility commission or board for the economic regulation of utilities. in many, but not in all provinces, these bodies also regulate tariffs and service quality of water and sewer utilities. under the constitution act, 1867, the provinces are "owners" of the water resources and have wide responsibilities in their day-to-day management. each province has its own legislation related to water resources, water supply and the environment. the federal government the federal government has certain specific responsibilities relating to water, such as fisheries and navigation, as well as exercising certain overall responsibilities such as the conduct of external affairs. within the federal government, over 20 departments and agencies have responsibilities for freshwater. the 1987 federal water policy, which remains valid today, has two main goals with respect to water: to protect and enhance the quality of the water resource and to promote the wise and efficient management and use of water. the canada water act (proclaimed on september 30, 1970) provides the framework for cooperation with provinces and territories in the conservation, development, and utilization of canada's water resources. the canadian environmental protection act, 1999, completes the framework for the protection and of water resources. environment canada is the federal department (ministry) in charge of conserving and protecting canada's water resources. health canada is the federal department in charge of protecting the health of all canadians by developing the guidelines for canadian drinking water quality in partnership with the provinces and territories. infrastructure canada, a department established in 2002, is a focal point for the government of canada on infrastructure issues and programs within the larger transport, infrastructure and communities (tic) portfolio. service provision service provision is the responsibility of about 4,000 municipalities. municipalities in canada are not mentioned in the constitution and thus depend heavily on provincial governments, which can create or dissolve municipalities, determine municipal responsibilities and what taxes municipalities can levy and set standards for service delivery. many provinces prohibit municipalities from running an operating deficit and restrict municipal borrowing to capital expenditures, while providing them conditional and unconditional transfers. while most municipalities provide water and sewer services directly, a few municipalities have delegated service provision to private companies or to public companies owned by provinces. for example, the ontario clean water agency (ocwa), a crown agency of the province of ontario, provides operation, maintenance and management services for more than 450 water and waste water treatment facilities in the province on behalf of about 200 ontario municipalities. metro vancouver provides treated bulk water to its constituent municipalities in greater vancouver, and collects and treats their waste water. overall there are approximately 9,000 public water and sanitation systems in the country. these include about 2,500 municipally owned water and sewer utilities in urban areas and approximately 6,500 small privately owned and operated systems providing public services in or at trailer parks and recreational facilities such as camp grounds, golf courses and ski facilities, etc. human resources some 300,000 canadians were directly employed in the operation of these municipal services in the late 1990s, and although statistics are not available for those employed in the private supplier sector, it is likely to be to the same order. business associations the canadian water and waste water association (cwwa), established in 1986, is a non-profit national body representing the common interests of canada's public sector municipal water and waste water services and their private sector suppliers and partners. cwwa is recognized by the federal government and national bodies as the national voice of this public service sector. tariffs and cost recovery tariff structure in 1999, 44% of canadian residences served by municipal water systems were not metered. a 2001 study of rate structures by environment canada showed that in 1999, 43 percent of the population was under a flat rate structure where the charge or assessment is fixed, regardless of the amount of water used. another 12 percent were under a declining block rate structure (where the consumer's bill rises at a slower rate as higher volumes of water are used); i.e., the more you use, the less you pay per unit. thus 55% of canadians faced residential water use charges that discouraged water conservation. water use was 70% higher when consumers face flat monthly rates rather than volume-based rates. only about 45 percent of the population served was found to be under a rate structure that provided an incentive to conserve water: 36 percent were under a constant rate structure (where the bill to the consumer climbs uniformly with the volume used); and 9 percent were under an increasing block rate structure (where a successively higher price is changed as larger volumes of water are used). tariff level the price canadians pay for water varies significantly across the country. analysis of the 1999 municipal water pricing survey prepared in 2001 indicates that the average domestic water user (assuming 25 000 liters per month) pays can$1.14 for 1000 liters. this value has increased substantially in recent years from about 82 cents per 1000 liters in 1991, and nationally, now includes a waste treatment component of about 39%. the municipal water and waste water survey covered over 1200 canadian municipalities. list of water and sewer rates in canada by municipality cost recovery according to the 1987 federal water policy the federal government is committed to the concept of "a fair value for water." to implement this concept in federal policies, programs and initiatives, the federal government has committed, among other things, to endorse the concept of realistic pricing as a direct means of controlling demand and generating revenues to cover costs. nevertheless, in 1999 only 50% of the cost of maintaining and operating water infrastructure was actually being met through cost recovery from users of the systems. investment and financing investment needs according to the national round table on the environment and economy, unmet water and wastewater infrastructure needs in canada were can$38–49 billion in 1996, and capital costs for the following 20 years would be in the order of can$70–90 billion. financing it was estimated that in the late 1990s the total annual operating cost of water and sanitation services were greater than us$2.75 billions while the revenue generated from user fees is to the order of us$2.1 billions. the difference is made up from general municipal revenues (e.g., property taxes or subsidies from senior levels of government). the greatest portion of investment in water and sanitation infrastructure and services has been financed by municipal governments from revenues derived from general property taxes or from water and sanitation charges which are increasingly moving to the state of full cost pricing. all provinces and territories provide funds via transfers to the municipal governments in their jurisdictions. the federal contribution, while significant in absolute terms (for example, in the period 1993 to 1998 the amount was in excess of us$1.4 billion), represents only a small proportion of total public investments in municipal infrastructure. provincial financing provinces provide both conditional grants (more than 80%) and unconditional grants (less than 20%) to municipalities. conditional grants can either be lump-sum payments (non-matching transfers) or matching grants. matching grants provide a certain percentage of financing that varies among provinces and programs, while requiring the balance to be paid by the municipality. federal financing infrastructure canada manages a number of federal funds financing investments in canada's infrastructure. none of these funds is dedicated exclusively to water supply and sanitation. the funds managed by the department include three funds under the building canada program: can$8.8 billion for the building canada fund (bcf), which is being used for core national highway systems, drinking water, waste water, public transit and green energy, as well as other projects; can$25 million a year in base funding to each province and territory, for a total of $2.275 billion over seven years; and can$11.8 billion for the gas tax fund, which invests in municipal infrastructure that contributes to cleaner air, cleaner water and reduced greenhouse gas emissions and supports better community planning.
