Sewage Treatment Plant

Sewage treatment plants are highly effective at treating waste and have very low impact. They use bacteria to remove up to 97.8% of the pollutants, before discharging the effluent into a (much smaller) drainage field. They are therefore suited to even the most sensitive sites such as close to freshwater lakes, rivers and streams - or where the water table is very high. Maintenance and running costs are relatively low for sewage treatment plants.

 Sewage treatment systems work in a similar way to septic tanks, with sewage first flowing into the first chamber of the treatment plant. In this chamber, grease, oil and scum will be separated onto the top of the tank, with the solids settling on the bottom. The liquids in this chamber are moved onto a second section, where air is pumped into it to grow the amount of aerobic bacteria in this sewage, which will break down the contaminants in the water. Once this water has been cleaned, this liquid moves onto a final settlement tank, where the few remaining solids are allowed to sink to the bottom of the tank before its contents are discharged into a soakaway or watercourse.

Wastewater Treatment

There are 3 main stages for wastewater treatment.

1. Sewage flows from the property into the first chamber of the sewage treatment plant. Here, the water sits until grease, oil and scum have floated to the top and solids have settled on the bottom of the tank.
2. Once the process of separation has taken place, the liquid travels into a second chamber. This chamber is fitted with an air pump or blower that circulates air around the chamber to encourage the growth of aerobic bacteria. This bacteria helps to break down the contaminants in the water.
3. The final stage of a sewage treatment plant is one last settlement tank. This final tank allows the very last solids that may remain to sink to the bottom of the tank before the effluent is discharged into a soakaway or watercourse. Once the treatment process has been completed, it can be discharged into a soakaway pit or water course.
