Welcome to InSite Water SA

What is InSite Water?

Rainwater Tank Sizing

Volume management and ‘source control’ reduces runoff volume, downstream flooding and helps restore stream flows. InSite water will help optimise the size of rainwater retention tanks and water infiltration pits.

Detention Tank Sizing

Stormwater flow reduction (detention / retention) protects existing Council stormwater assets that are nearing capacity or already overcapacity. InSite Water will help you size stormwater detention tanks to meet Council requirements.

Water Quality

Improving stormwater runoff quality improves the health of our rivers and coastal areas. We help you design Water Sensitive Urban Design (WSUD) treatments for smaller sites including: raingardens, infiltration, bioswales, swales and green roofs

Water Efficiency

InSite Water helps you specify water efficiency for your project to save money on bills and to increase your project’s drought resilience. This includes appropriate use of rainwater and water efficient appliances.

InSite Water is an integrated water management and stormwater assessment tool for use on small-scale development sites (less than 5,000 square metres) in South Australia that need quick and accurate design answers. This site will allow you to optimise design solutions to manage stormwater runoff, assessed against the SA Water sensitive urban design policy and agreed Council performance criteria.


This toolkit is under development and it has been created for testing and consultation purposes.  Please note that engineering calculations and features have not been finalised and we may evolve and change the way outcomes are measured and calculated.
