Wash Water and Paint Waste on a Court Job in Adelaide

What tennis court resurfacing in Adelaide actually involves

For a high-pressure cleaner, EPA South Australia's advice is to ensure that all waste water is directed to a soakage area such as the garden or lawn. Its list also names paint and paint scrapings.

What the data sheets add

The first manufacturer's data sheet says: “Pressure clean surface with high pressure wash”. It also says: “Clean up with water”. The second manufacturer's data sheet says: “After each use, promptly clean all equipment with water.” It also says: “Refer to state / local EPA and council websites for environmental and safe disposal details.” EPA South Australia's page is the South Australian rule; the sheets are product statements.

What to ask

A coating that cleans up with water still produces wash-up water, and a court cleaned under pressure produces blasting waste. That is our reading of the two sources, not a rule either one states. Ask where each will go, who is responsible for it, and whether the quote says so.

Stormwater is part of some courts' surrounds: the City of Norwood Payneham & St Peters lists stormwater infrastructure among what its Payneham Oval upgrade removed, which is in the Payneham page. The full list of EPA South Australia's lines, each with its read date, is in the rules check on the costs page.
