396 Dr CLOSE (Port Adelaide—Deputy Leader of the Opposition) (3 February 2021). In relation to the Community Wastewater Scheme (CWMS) in Tea Tree Gully:

(a) When does SA Water intend to start works on the CWMS transition?

(b) Is the $65 million announced by the state government adequate to transition all 4,700 households' residential infrastructure along with the street infrastructure that will need replacing?

(c) Has the minister or his office ever directed SA Water not to deal with or seek the minister's permission first before dealing with certain members of parliament or City of Tea Tree Gully councillors for matters relating to the CWMS upgrade?

(d) If SA Water chooses to use a pressure sewer option in this project who would own the infrastructure?

(e) If SA Water uses a pressure vacuum sewer option, is it possible that households would be charged a service fee for this option?

(f) Will SA Water be responsible for operating, maintaining and renewing the low-pressure sewer systems as required?

(g) Will the customer receive an electricity rebate for the additional electricity cost of operating the system?

The Hon. D.J. SPEIRS (Black—Minister for Environment and Water): I have been advised:

Longstanding and accepted protocols, consistent with usual government practices regarding SA Water and its dealings with members of parliament, have been the basis for interactions to date.
