WA Govt release potential network models for CDS

Two potential strategies for WA’s container deposit scheme (CDS) have been released, with the preferred option aiming to establish a full-time refund point for every 20,000 people.

A draft released by the WA Department of Water and Environment Regulation’s (DWER) highlights two options to achieve minimum service standards for approximately 98.8 per cent of the population.

DWER’s preferred option is expected to deliver a net present value of $152 million, with a benefit-cost ratio of 1.31. It will involve establishing one full time refund point for major regional centres with populations between 10,000 and 20,000 and at least two full time refund points for major regional centres above 20,000. A population threshold of 500 is set for flexible refund points.

Modelling from Australian Bureau of Statistics 2016 Census data suggests this will require a minimum of 196 refund points, made up of 111 full time refund points and 85 flexible refund points.

The alternative option is to provide a full-time refund point for every 15,000 people, which would mean a minimum of 228 refund points, made up of 143 full time refund points and 85 flexible refund points. This option is expected to deliver a net present value of $123 million, as a benefit-cost ratio of 1.28.

The draft aims to balance the cost and convenience of the container deposit scheme and has been released during the Request for Proposal for the scheme coordinator to inform the respondents in the development of their offers.

DWER will analyse submissions and make recommendations to the Minister for Environment and form the part of the development of the state-wide collection network as stage two of the Request for Proposal period.

Submissions close on 6 December. For more information, click here.
