Similar to drinking water provisions, the federal government has delegated responsibility for wastewater treatment to the provinces and territories. There are two federal acts, however, that may apply to wastewater. The Fisheries Act prohibits the release of harmful substances into waters that fish live in. The Canadian Environmental Protection Act governs the release of toxic substances into the environment and allows the federal government to develop regulations for the use of toxic substances.
How to reduce pressure on septic system?
Following some water conservation practices can greatly reduce pressure on your septic system. For more information about conserving water, see the fact sheet about Water Consumption. Here are a few things that you can do to care for your septic system: 1 Do not use your drain or toilet as a garbage disposal; avoid putting dental floss, diapers, coffee grounds and paper towel down the drain, as they can clog up your septic system. 2 Spread your loads of laundry out over the week. When too much water is added to the septic tank, it does not have time to treat wastes, and you could be flooding your drainfield with wastewater. 3 Plant grass on your drainfield, but keep trees and shrubs away from it, because roots can clog the system and cause damage. 4 Do not drive on your drainfield, because this can compact the soil and damage the septic system components.
Why is oxygen important in wastewater treatment?
The oxygen helps the bacteria to digest the pollutants faster. The water is then taken to settling tanks where the sludge again settles, leaving the water 90 to 95 percent free of pollutants. The picture below shows the settling tanks in the Winnipeg Wastewater Treatment Plant.
How is sludge treated?
The sludge that is removed from the settling tanks and the scum that is skimmed off the top during the primary steps are treated separately from the water. Anaerobic bacteria (anaerobic bacteria do not require oxygen) feed off of the sludge for 10 to 20 days at temperatures around 38 degrees Celsius. This process decreases the odour and organic matter of the sludge, and creates a highly combustible gas of methane and carbon dioxide, which can be used as fuel to heat the treatment plant. Finally, the sludge is sent to a centrifuge, like the one shown in the picture below. A centrifuge is a machine that spins very quickly, forcing the liquid to separate from the solid. The liquid can then be processed with the wastewater and the solid is used as fertilizer on fields.
Why do cities dump raw sewage?
Some cities choose to dump raw sewage into the oceans and rivers, because it is cheaper than effective treatment . A report published by Sierra Legal found that, of 22 Canadian cities, Victoria, Dawson City, Montreal, Saint John, Halifax and St. John’s dump some or all of their raw sewage directly into water bodies. While not all of the sewage is dumped directly into the oceans, these six cities produce 400 million litres of raw sewage each day! Montreal dumps around 3.6 billion litres of raw sewage into the St. Lawrence River each year, and Victoria is the only large Canadian city to dump all of its waste into the ocean without any attempt to improve the system. The city of Victoria dumps more than 34 billion litres of raw sewage into waterways each year, and still claims that their actions are not harming the environment! Halifax and St. John’s have plans to construct wastewater treatment facilities, but in the meantime, are still discharging 65.7 billion litres and 33 billion litres, respectively, of raw sewage into the Atlantic Ocean. For more information about water pollution, see the Water Pollution fact sheet, or the Operation Water Pollution lesson plans and resources.
Parts of a Wastewater Treatment System
Wastewater treatment systems contain several parts, each vital for efficient operation. It’s important to understand each part of a wastewater treatment system before planning and constructing one.
Planning a Wastewater Management Project
Early in the planning stage, it’s best to understand all industry standards and regulations thoroughly. Doing so allows for fundamental decision-making, such as determining target purity. Industry standards may be complex when involving high-pollutant wastewater or high purity effluent standards.
Why Is Wastewater Management So Expensive? Important Factors to Consider
Both residential and industrial water treatment can be expensive. Treatment systems utilize advanced technology, often involving large equipment in multistage facilities. Many different factors influence the cost of a wastewater treatment system, including the following:
Increased vs. Decreased System Automation
An increased level of automation serves several purposes. It minimizes the risk of human error and decreases long-term labor costs. High automation may reduce the lifetime operating costs of a wastewater treatment system. Automated equipment and features tend to be more expensive than their manual counterparts. Initial expenses might be greater.
How Long Does It Take to Build a Water Treatment Plant?
Keep in mind, the construction or installation period can take weeks, months or even years, depending on the scope and complexity. The installation timeframe is an important factor to consider, as longer timeframes incur greater costs.
How Expensive Is the Process of Filtering?
Once a system is installed, filtering costs vary. In many cases, systems with high initial values offer favorable upkeep costs. For instance, inexpensive systems may require more frequent filter changes for adequate function. Consider the long-term filtering costs of your chosen wastewater treatment system type.
Average Cost of a Wastewater Treatment Plant
Wastewater treatment plant costs vary by system type, industry, location and other factors. When determining a price estimate, consider these factors and the impact they might have.

How much water is lost in the outdoors?
That's equivalent to the amount of water needed for the average family to take 1 year's worth of showers. As much as 50 percent of the water we use outdoors is lost due to wind, evaporation, and runoff caused by inefficient irrigation methods and systems.
Why are water and wastewater price escalation rates needed?
Annual water and wastewater price escalation rates are needed in LCCAs to estimate the overall cost savings of water efficiency projects. However, determining appropriate forecasts of water and wastewater price escalation rates can be more difficult than ascertaining comparable rates for various forms of energy. While the EIA forecasts future changes in energy prices, no governmental organization projects future changes in water and sewer prices. Energy prices are also significantly driven by commodity prices, whereas infrastructure projects often drive large variances in price esca lations across water and sewer service providers. The preferred source for a forecast of annual water and wastewater price escalation rates is the local water or wastewater utility. The serving utility can be contacted to determine if there are any forecasts of future water and wastewater rate changes, whether published or via a written statement or other documentation from the utility. If possible, obtain year-specific price escalation rates, rather than a multi-year average, for use in the LCCA. The Building Life Cycle Cost program,7for example, allows entry of such year-specific rates. Absent a forecast from the serving water or wastewater utility, the next recommended method for forecasting water and wastewater prices is to look to past local rate changes as a general prediction of future rate changes. To determine historical annual rates of change, collect at least 5 years of past billing statements or rate data from the local utility and use the equation presented in Section 2.3 of this document to calculate an average annual price escalation rate. Other important guidelines for this option include the following: When directly calculating the average annual price escalation rates, make sure to use marginalrates (typically $/kGal or $/100 ft3) rather than averagerates. Do not simply take a bill total and divide it by total usage to obtain an average rate. Rather, obtain the volumetric charge for water (and wastewater, as relevant), which should be stated on the bill or provided by the serving utility in their rate schedule. In some cases, the average and marginal rates can differ tremendously, and water efficiency projects avoid costs at the marginal rates. If monthly rates differ within a calendar year, choose the historical rates from the same month of each year. For example, choose the rates from January or December of each year. Finally, calculate water and wastewater price escalation rates separately. If past billing data is not available and the local utility cannot provide price escalation rates, the results of this study may be used to approximate rates of price escalation. When relying on price escalation rates from this analysis, the analyst may use differing criteria to select appropriate rates, depending on the type of project and region in which the water efficiency project is located. For example, in some cases it might be appropriate to find utilities in a similar region and/or perhaps of a similar size. In other cases, the analyst might consider the base volumetric water rate when selecting a representative price escalation rate. Statistics on these characteristics are provided in Sections 3.1 and 3.2 of this report to assist with this selection process. While the historical price escalation rates presented in this report could help inform a regional LCCA study, it is important to note the limitations and caveats of this dataset: Limited Sample:The sample size is limited, and the data does not reflect a balanced geographic distribution, nor does it represent some of the more populous cities throughout the U.S. In some cases, a region is represented by only one or two utilities.
How to capture the marginal cost of water and wastewater?
To capture the true marginal cost of water and wastewater services over time, the analysis focused on volume- based charges . An effort was made to avoid fixed fees as part of the rate. It was determined that the 8-inch water meter size industrial consumer class reflected an appropriate commercial volumetric rate in most cases. This is because this class of consumer typically pays a relatively smaller portion of maintenance and infrastructure fees compared to the total volume of water and wastewater that they consume. This, in effect, dampens out the flat fixed fees and approximates more closely the marginal cost of water and wastewater. The rates per kGal in 2016$3are provided in Figure 1 and Figure 2 for 61 water utilities (Figure 1) and 39 wastewater utilities (Figure 2), ordered from lowest to highest rates per kGal. There is a large variation in rates across these utilities, likely due to infrastructure investment requirements. For example, the wastewater rate for Seattle is notably higher than for other cities analyzed in this study (see Figure 2), likely driven by Seattle’s required investments to address sewage infrastructure and overflow into the Puget Sound (Thompson 2014).
What is AWWA water?
The AWWA is a nonprofit water-industry-focused association dedicated to providing information and solutions related to effective water management. The AWWA water and wastewater rate surveys collect information on the water and wastewater rates and associated fees and charges from communities across North America, inclusive of the United States, Canada, and Puerto Rico. Each survey breaks down the utilities surveyed by location, demand, and revenue received over the previous 2 years for both water services and wastewater services. Water services include collection and management of source water treatment to potable water standards, and distribution. Wastewater services include collection and treatment to permit requirements for discharge. To carry out this analysis, the results of the 2008, 2010, 2012, 2015, and 2016 AWWA water and wastewater rate surveys (AWWA and RFC 2008, 2010, 2012, 2015, 2016)1 were compiled and examined.
Does the average rate per gallon vary across all utilities?
Although rates vary across all the utilities in the observed sample set, the average rate per gallon across all of the surveyed utilities has steadily increased over the periods examined.
