(1) How many customers does ACTEW have for grey water.

(2) What tariff is used to set the price of grey water.

(3) Why are the rates for grey water "commercial in confidence" when other water usage rates are not.

Note: The normal definition of 'grey' water is the water leaving a household excluding water from the toilet. ACTEW's significant re-use schemes are for the re-use of sewage effluent (i.e. treated sewage, including water from the toilet). We have taken these questions to refer to treated sewage rather than grey water per se.

ACTEW treats the sewage to provide effluent of a quality consistent with the "uncontrolled access" category of the ACT Water Reuse Policy. While this effluent is not drinkable, it is of a quality that would make it difficult to distinguish a glass of effluent from a glass of potable water.

1. How many customers does ACTEW have for grey water?

In 2000 ACTEW Corporation provided the following customers with treated effluent:

� Woodhaven Green Golf Course and BRL-Hardy vineyard (from Lower Molonglo Water Quality Control Centre); and

� Southwell Park (from Southwell Park Treatment Plant).

The following customers are soon to be supplied with treated effluent:

� ACTEW signed a contract with the Department of Defence for the supply of effluent to ADFA and Duntroon from the North Canberra Effluent Reuse Scheme (NCERS), representing 40 Ha of land to be irrigated.

� ACTEW agreed contracts with the ANU, Bureau of Sport and Recreation and Canberra District Rugby League for supply from NCERS. Final signature is awaiting concurrence from the Department of Health and the Environment Management Authority on water sampling issues. This represents another 20 Ha of irrigation on various ovals in North Canberra.

These customers are currently supplied with potable water. The pipework systems are already in place. Following the satisfactory conclusions to negotiations with the relevant parties, ACTEW will supply treated effluent from NCERS.
