The difference between Gravity and
pumped sewage treatments systems

 

 

Need help with your septic tank conversions and sewage treatment options?



Gravity Sewage Treatment System

Gravity sewage treatment systems rely on the final effluent flowing by gravity to its final destination. In the image below the final effluent from the Gravity Sewage Treatment system flows downhill to a watercourse.

Gravity systems have the following advantages

  • Unit cost is lower
  • They use less electricity than pumped outlets.
  • On a pumped version the treatment plant will fill if the electricity fails
  • Sewage treatment plants are available with the following outlet depths 550, 850, 1100 and 1100+
 

Pumped Sewage Treatment System

In some instances a pumped outlet is required. A pumped outlet maybe required when a receiving watercourse or drainage field is a great distance away or incoming drains are deep. The follow is an example of a Pumped Sewage treatment system which has been installed and is pumping the final extent to a drainage field.

Pumped outlets have the following advantages

  • Units can be installed flush in the ground
  • Final effluent can be pumped uphill or to a high level drainage field
  • While receiving watercourses are susceptible to rising levels. Pumped outlets can prevent back filling into the sewage treatment plant.
