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.
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.
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.
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.
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.
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:
Size Range: 80 mm – 375 mm.
Flow Rate: 2 L/s – 200 L/s.
