Treatment plants have a really important role. Keeping them well maintained is vital to ensure that they continue to work properly and we can continue enjoying the benefits of modern sanitation and a clean environment.

How do treatment plants work?

Treatment plants are used to treat wastewater when a property isn’t connected to mains drainage.

Treatment plants consist of three chambers. The first chamber is where sewage rests, letting oil and grease float to the top with solids resting at the bottom. From here, liquid travels to the second chamber, which has an air pump to circulate air, in order to grow the bacteria that helps break down contaminants in the water.

Finally, in the last chamber, remaining solids sink to the bottom and the cleaned water is discharged from the tank to a soakaway or watercourse.

What happens if treatment plants aren’t cleaned properly?

Treatment plants perform an important function and need to be maintained and serviced properly so that:

  • The plant can work effectively, stops it from breaking down and creates the right environment for the bacteria to do its job.
  • Pollutants are prevented from escaping and damaging the surrounding environment or polluting nearby watercourses.
  • You avoid a fine by the Environment Agency for not fulfilling your duty to ensure the proper operation of your treatment plant.
  • The cost of replacing parts that haven’t been looked after is prevented
  • Smells from blockages don’t back up into your property.
  • The life of the treatment tank is extended by keeping it well maintained.

Depending on size and the amount of people using it, treatment plants should be cleaned every six to twelve months to be sure they work efficiently.
