Wastewater plants and drinking water systems can account for up to one-third of a municipality’s total energy bill (EPA 2009a).
How does wastewater treatment affect water quality?
Wastewater is treated to remove pollutants (contaminants). Wastewater treatment is a process to improve and purify the water, removing some or all of the contaminants, making it fit for reuse or discharge back to the environment.
How does wastewater treatment affect the environment?
Conventional wastewater treatment plants (WWTPs) clean wastewater and minimize water pollution; but, while doing so, they also contribute to air pollution and need energy/material input with associated emissions.

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.

Why do people go bottled?
Due to the potential presence of harmful pollutants in the water, many people resort to going bottled whenever possible. The problem here is that many of these water bottles do not find their way to proper recycling centers. As a result, too many of these bottles end up in landfills or, worse yet, as litter in nature.
Does plastic degrade easily?
Plastic does not degrade easily, so when water bottles are left out to rot, the results can be devastating given enough time. Positive water treatment effects therefore include the reduction of bottled water purchases, since the tap is a cheaper option. With fewer bottles on the market, the environment can rest easy.

What is activated sludge?
The wastewater then undergoes a biological process known as activated sludge process, which uses natural occurring micro-organisms to break down dissolved and suspended organic solids.
Why is sludge treated?
The sludge collected during the treatment process is itself treated because it contains a large amount of biodegradable material. It is treated with anaerobic bacteria in special fully enclosed digesters heated to 35 degrees Celsius, an area where these anaerobic microorganisms thrive without any oxygen.
