Regional Wastewater Treatment Plant Rehabilitation Program

Regional Wastewater Treatment Plant Rehabilitation Program

What is the project?

We are undertaking concrete rehabilitation works at a number of our regional wastewater treatment plants across the state; including.

  • Angaston
  • Gumeracha
  • Heathfield
  • Millicent
  • Mt Burr
  • Myponga
  • Nangwarry
  • Naracoorte

Why is it important?

This investment will improve the reliability of the existing wastewater network and reduce the risk of overflows into the environment.    

What can I expect?

SA Water and our contractors are committed to keeping construction impacts to a minimum. However during construction residents closest to our sites may notice work crews in the area and some temporary noise or dust associated with the works.

The majority of construction work will take place from 7am to 5pm on a rotated schedule.

There will be disruptions to water supply. If your property is affected, you will receive advance notification at least four days’ prior to any water supply disruptions.

How long will it take?

Our tank renewal works are to be progressed over the next three years. Works at individual sites are expected to take between 2 – 5 months to complete.

This timeframe may change as a result of technical constraints or poor weather.

Where can I go for more information?

Local residents and businesses will receive further notification about the works as construction progresses.
