Helping TasWater to develop a strategy for key asset groups

Development of a Water Main Condition Assessment Strategy

When Tasmanians turn the faucet, they expect safe, reliable water. Keeping the water flowing is the responsibility of TasWater, which provides water and sewerage services across Tasmania through assets including 70 drinking water supply systems, 6,600 kilometres (4,101 miles) of water mains, and 202,000 connections.

Effective management of these assets is key to maintaining the reliability customers expect and the efficiency stakeholders demand. We worked with TasWater to develop a water main condition assessment strategy as part of its overall development of asset management class plans. We developed the strategy through a comprehensive process including a literature review, stakeholder engagement, and collaboration with subject matter experts.

The strategy developed included a performance review of TasWater water mains within the scope of the strategy, detailed descriptions of available water main condition assessment techniques, and assessment of their capabilities against a number of criteria. We also developed an overall implementation plan for a water main condition assessment program including identification of prioritized improvement activities.
