Calculate your drainage contribution
Drainage contributions are the costs we recover from developers to fund drainage scheme infrastructure and stormwater quality treatment works. These costs are then reimbursed to the developers that construct the scheme works.
Contributions are based on the area developed and the development type. For example, industrial development pays a higher rate than low-density residential development.
- The table below shows the rates per hectare for each drainage scheme.
- Use the calculator below to calculate your contribution based on your development type and size.
- You can get a discount on the stormwater quality component of the contributions if you build your own stormwater quality works, in addition to any stormwater quality works proposed in the scheme. The calculator will show the discount based on the level of ‘best practice’ proposed.

The calculator stipulates the level of best practice expected within a development. The level of treatment achieved (% of best practice) can be increased beyond the expected amount or decreased where mitigating circumstances prevent local treatment.
This calculator is provided for illustrative purposes only as it is not possible to provide for all special conditions which may apply in particular circumstances. The results generated are based on the accuracy of information and on the assumptions shown or selected by you. The information which you calculate using this calculator is an approximate guide only and the existence of a printout does not constitute any agreement on the level of developer contributions which will apply. The terms and conditions for particular development schemes may be varied or introduced in the future. Fees and charges may by payable. For confirmation of contributions payable please submit a formal application for conditions to the Land Development Team at Melbourne Water by filling in the Application for Conditions Agreement
