Our Waterways and Drainage Investment Plan (WDIP) details our responsibilities, goals and service levels for our waterway management and drainage services. Download the latest plan or view progress on our commitments.
The five-year Waterways and Drainage Investment Plan outlines our program of works to:
- maintain and improve the rivers, creeks and estuaries in our region
- protect and prepare the community when it floods
- manage stormwater.
These works are funded by property owners across the Port Phillip and Westernport region through our Waterways and Drainage Charge.

Our 2021-26 Waterways and Drainage Investment Plan was developed to support our 2021 Price Submission. This proposes prices and standards for our services – including waterway management and drainage – and is subject to approval by the Essential Services Commission. The Commission released their final decision on our prices on 22 June 2021, which can be viewed on the Essential Services Commission’s website.

Assessing our progress
Our current investment plan for 2021-2026 includes 19 targets and associated performance measures, against which our annual progress is independently assessed. The results are published on this page and in our annual report.
The following criteria are used to measure what we’ve achieved:
- Met – 100% of measures are achieved and or the target value is achieved
- Substantially met – 80% of measures are achieved, target value is met on measures achieved and target value is likely to be achieved over the five year period
- Not met – the specification for this target has not been satisfied for the period assessed. That may be due to internal or external factors; all factors are recorded in the assessment. Target value may or may not be achieved over the five year period.
- Not scored – target is not applicable to the yearly reporting period as these targets are measured over longer timeframes.
