Project teams from SA Water and John Holland will be at Murray Bridge Marketplace from 3-7pm on Thursday to answer questions about the imminent construction of the city's new waste water treatment plant.
The plant will process up to 4.6 million litres of effluent per day at a site on Pfeiffer Road at Brinkley.
Eighteen kilometres of pipes and four pumping stations will also be built to connect it to the city's sewage system.
SA Water spokeswoman Anna Jackson said the visit would also give an opportunity for plumbers, mechanical and hydraulic experts, lunch truck operators and other suppliers to register their interest in contributing to the project.
Construction is due to begin in October.
