Lower Molonglo Water Quality Control Centre

(Question No 1283)

Mrs Dunne

asked the Treasurer, upon notice:

(1) When was the Lower Molonglo Water Quality Control Centre completed;

(2) What was the projected population that would be served by the plant at the time of completion;

(3) Has the population projection to be served by the plant been revised since completion;

(4) If it was revised, (a) why was it changed and (b) what is the current population projection;

(5) What factors have caused any changes to projections.

Mr Quinlan

: The answer to the member's question is as follows:

(1) May 1978.

(2) 269,000.

(3) Yes.

(4) a)

ACTEW has advised me that the capacity of the Lower Molonglo Water Quality Control Centre is kept under regular review, based on current per capita flow data and actual plant process performance. The initial population capacity estimate of 269,000 was based on an anticipated inflow of 354 litres per capita per day. In 1992 the plant was reassessed as part of the Environmental and Process Audit. Based on inflows of 300 litres per capita per day, the plant was estimated to have a capacity sufficient to serve a population of 363,000 by 2002. A more recent study in 2002 indicates an actual inflow of 289 litres per capita per day.


I am advised that based on the 2002 revision, the current population capacity is approximately 377,000.

(5) ACTEW advises me that reduced per capita flow is likely due to more efficient consumption practices. These practices include greater community awareness, use of more efficient appliances, and regulatory changes such as the requirement for dual flush cisterns in new homes.

asked the Treasurer, upon notice:

In relation to the Independent Competition and Regulatory Commission pricing direction for A.C.T. water price increases, does the Government have any proposals for concessions to large families.
