Answer
(a)
There are 106 wastewater treatment plants (WWTPs) managed by the Water Corporation.
In addition, there are a number of small wastewater plants owned by other groups.
(b)-(g)
[See tabled paper no.]
(h)
For regional WWTPs, the geographical areas served for each plant is as per the name of the WWTP.
For the metropolitan WWTPs, the attached map [see tabled paper no.] depicts the geographical areas served.
(i) - (l) [See tabled paper no.]
(m) - (o)
Wastewater treatment plants in all cases form part of a Scheme. A Scheme incorporates wastewater treatment plants, reticulation, pumping stations and discharge options. Costs and charges are calculated at a Scheme level.
The wastewater treatment plants in isolation do not generate revenue from the wastewater rates and fees, the Scheme does, and the operating subsidies and other requested information equally relates to the total Scheme rather than any part of it.
From the 106 WWTPs listed, 96 WWTPs are part of Schemes that are subsidised by the State Government.
The remaining Schemes are not subject to an operating subsidy.
