Eudunda Stormwater Capture and CWMS Upgrade

Project background and challenges

• Small farming community in the midNorth of South Australia.
• Existing Community Wastewater Management System (CWMS) installed in the 1970’s – ageing infrastructure.
• Inadequate stormwater detention leading to frequent flash flooding of large township areas.
• Basic wastewater treatment capability – facultative lagoon • Underutilisation of stormwater and wastewater resource.
• Excessive consumption of potable water for irrigation and limited volumes available – reduced amenity value.
• Complicating factors such as works scheduling, existing infrastructure, road design and budget.

Scope, solutions and results

• New stormwater detention dam by Council. HDS proposed interception of this for diversion to winter storage.
• New pump station, wastewater treatment plant, 20 ML winter storage facility and replacement/upgrade of rising main.
• Project planning, options proposal and scheduling of works allowed for overall implementation cost reduction.
• Increased water resource and new irrigation opportunities.
• Telemetry link allows for reliable measurement and pond level management.
• Multi-discipline approach by HDS allowed for re-design of road intersection and optimisation of intercept sump location.
