Waste water treatment
It starts off with the house plumbing. First off it starts with the bar screen that takes away the waste and garbage. Next would be the grit tank which lets the sand, gravel and etc to settle at the bottom.Next the primary settling tank which lets the water settle for several hours. Next the clarifier which create micro organisms which eats the organic matter. .The final treatment is when they add chlorine to clean the left over contaminants.

The goal of wastewater treatment is to protect and maintain healthy rivers and oceans. If pollutants in wastewater are not removed, they flow directly into our waterways. This can threaten public health, fisheries, wildlife habitat, recreation opportunities and ultimately, our quality of life.
Primary treatment
Primary treatment is a mechanical process that removes materials that settle or float. It removes 50 to 60 per cent of the total suspended solids (TSS) and 30 to 50 per cent of the biochemical oxygen demand (BOD). The Iona Island and Lion’s Gate waste water treatment plants provide primary treatment. Secondary treatment
Secondary treatment is an additional treatment step that takes place after primary treatment. Secondary treatment is a biological process that uses aerobic bacteria to consume suspended solids and dissolved organic materials in waste water. Secondary treatment plants remove about 95 per cent of the organic materials in wastewater. The Lulu Island, Anacin Island and Northwest Langley waste water treatment plants provide secondary treatment.
