Our Mechanical Workshop at WET is a leader in pump refurbishment, iron bacteria control and water meter testing. Our teams can overhaul and repair larger pumps and valves at a much lower cost than it would take to replace them.

Pump Refurbishment

The workshop is able to repair, overhaul, refurbish or enhance the performance of most water or wastewater pumps or valves. We are experienced in modern maintenance methods and can extend the time between overhauls.

Improvements include:

  • Efficiency enhancements.
  • Corrosion and cavitation protection.
  • Reseating and rebuilding of impeller seal rings.
  • Repair of stuffing boxes, neck bushes, shafts and casings.
  • Rebuilding pump impellers and casings.

Epoxy Coating

The use of epoxy coating and the modification of pump units to accept mechanical seals, increases pump efficiencies. It also helps with the drive to extend overhaul periods.

We constantly evaluate the processes we use in the development of new products. This system has meant that overhaul periods have increased from 2-3 years to 8-10 years.

We undertake rigorous performance monitoring before and after coating. Our teams will only schedule an overhaul where significant efficiency gains and performance reliability improvements can be achieved.

Iron Bacteria Control

The fouling of ground water or drainage pumping systems by iron bacteria is a worldwide problem. It results in impaired hydraulic performance, increased pumping costs and corrosion. At WET we have developed a solution to control iron bacteria.

How we do it

SA Water has patented a technique involving in-situ generation of chlorine by electrolysis of groundwater. This technique has proved to be very effective in controlling iron bacteria.

Some bores that would have previously lost up to 45% of their flow within 50 days of the installation of a new pump have now operated continuously for over three years with no loss of flow caused by iron bacteria.

Meter Testing

The Mechanical Workshop can offer a full range of meter repair and accuracy testing for water meters from 80 mm to 375 mm.

Our services include:

  • Meter testing.
  • Meter calibration.
  • Accuracy certificates.

Size Range: 80 mm – 375 mm.

Flow Rate: 2 L/s – 200 L/s.

  • Water Quality
  • Customers in the southern suburbs through to the Adelaide CBD may notice a temporary change to the colour of their water. The water remains safe to drink.

    Suburbs affected may include:

    Clapham, Pasadena, Cumberland Park, Westbourne Park, Kingswood, Goodwood, Keswick, Unley, Panorama, Belair and Adelaide CBD.

    We have begun flushing parts of the surrounding network as a result of new pipe work being installed to support the South Road Darlington Upgrade works. We will continue to test the water quality and are in contact with SA Health. All test results are compliant with the Australian Drinking Water Guidelines. At this stage we anticipate the water will return to normal by late this evening.

    If you have concerns, please contact us on 1300 SA WATER.
