Section3 provides guidance on planning your approach towater conservation. If you have limited time andresources, you could focus on changing Council plansand policies, as outlined in Section 4.Saving water in Council operations will reduce yourCouncil’s water bills and the savings can be used inturn to fund other programs.

A sample SOJI is included in Section 7.The International Council of Local EnvironmentalInitiatives (ICLEI) has developed a new program forCouncils, the ICLEI Water Campaign. ICLEI will buildon the work of the WCPP to facilitate councilsundertaking the ICLEI Water Campaign. The Water Campaign provides Local Governments with a framework for addressing their unique local water management concerns while contributing to an international effort to mitigate the current global water crisis. It was developed in response to the mandate that ICLEI was given by its membership in 1995 to develop an international campaign focusing on water. The Water Campaign focuses on the need to improve dialogue between water managers and water users. This dialogue begins with improved water management within Local Government itself, and extends to the community and the watershed area. Improving Local Government service delivery places value on community input and participation. This participatory approach to water management recognises that modern water management solutions are increasingly non- technical in their emphasis.10 Water Conservation Handbook

For example:Q quick wins that can be implemented immediately (excellent returns with no or minimal capital outlay);C attractive opportunities requiring some capital outlay (senior management approval may be required);L less attractive returns, lower priority initiatives; andI initiatives requiring further investigation.24 Water Conservation Handbook

    • Planning Sheet 44 Alternative supplies of water Introduction FIGURE 10 Unley Museum Rainwater Tanks Project Demonstration Site You can complement water conservation measures by reducing the use of mains water with alternative water supplies. Alternative water supplies include: 1. rainwater tanks; 2. aquifer storage and recovery; 3. greywater and blackwater; 4. reclaimed effluent; and 5. groundwater. 1. Rainwater tanks The capture, storage and use of rainwater can significantly reduce stormwater flows to the street and augment supply to Council owned and occupied buildings. Specific considerations for Local Government include: • although treatment of rainwater for residential purposes is uncommon you will need to consider treatment if installing a commercial system that provides drinking water (Contact the Department for Human Services for requirements on commercial systems). As Ultra-violet (UV) sterilisation is a proven technology ideal for rainwater treatment (owing to the low turbidity of rainwater); CASE STUDY: • rainwater tank systems are most effective at City of Prospect saving mains water and reducing stormwater A 91 000 litre underground rainwater tank is flows where they are fully utilised; and being installed as part of the City of Prospect’s • the cost-effectiveness of rainwater tank systems Civic Centre upgrade.
