What is InSite Water

InSite Water is an integrated water managment and stormwater assessment tool for use on small-scale development sites (less than 10,000 square metres) in Australia that need quick and accurate design answers. This site will allow you to optimise design solutions to manage stormwater runoff, assessed against the Water Sensitive Urban Design WSUD policy and agreed Council performance criteria.

InSite Water is designed and maintained by the team at Organica Engineering, an independent engineering consultancy specialising in partnering with other organisations on Integrated Water Management and other sustainability opportunities. We are based in Melbourne, Australia.

The InSite tool has been developed with the support of Manningham CouncilKnox Council and Melbourne Water.

Rainwater Tanks

Volume management 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 Tanks

Stormwater flow reduction (detention) 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.

Stormwater 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.

meet our TRAINER

Ian Adams is an experienced public speaker, workshop facilitator and trainer, regularly providing training at the highest levels in government and the building industry.  As the CASBE / MaV’s endorsed BESS trainer, he trained hundreds of planners, engineers, and building professionals on sustainable design. He is a certified assessor and trainer for the Green Building Council of Australia, regularly lectures at RMIT and Melbourne Universities on sustainable design and city infrastructure. Ian has been instrumental in helping develop industry toolkits such as InSite Water, BESS, Green Star, STEPS, the SDS planning assessment tool, and he has an in-depth knowledge of how to implement WSUD and sustainable design in buildings. Formerly he worked as Sustainability Coordinator for Frasers (Australand) guiding their implementation of ESD and WSUD into over 1,000 housing, industrial, commercial and apartment buildings.

Why Choose InSite?

InSite is the result of 5 years and $300k investment, is a collaboration of Stormwater Australia members, and has over 500 building design professionals and Council officers using it, including 10 Victorian Councils.

The InSite methodology is based on Book 9 of the ARR 2019, which was relaunched in March 2019. This as it is considered the primary text of the stormwater industry.

InSite Water aims to provide a way of undertaking the engineering calculations required by book 9 (the Urban Chapter) of the 2019 ARR, including providing the calculations and targets for relatively new concepts such as source control and volume management, while still providing calculations for more established methodologies like sizing a detention tank and measuring stormwater quality improvements in a system’s design.

Professional Solutions

Solutions for Civil and Environmental Engineers, ESD Consultants and Building Design Professionals. We help you to quickly create lot scale stormwater designs that meet Council and Water Authority requirements.

Complete Council Solutions

We work with Councils to help simplify the stormwater approvals process for both applicants and for Council officers. Our software covers both engineering and environmental aspects of stormwater.

Water and Planning Authorities

We can customise the tool to meet your local conditions and policy objectives. Whether it's water saving for drought resilience, flood prevention, or environmental protection controls, we can provide a mechanism for the building industry to demonstrate compliance.

Academic and Home Users

InSite Water has inbuilt training on designing stormwater systems to meet flood prevention guidelines and environmental outcomes. We support a free report for students and home users to learn about Integrated Water Management.

Our Approach

Continued Improvement

We, with the help of InSites users, are able to constantly update and upgrade InSite to reflect changes to industry standards.

This means that you can always be sure that your calculation methodology is up to date and your projects for small scale development are meeting the criteria in multiple areas.

Asset Longevity

The team at InSite wants to make sure that we are extending the useful life of existing council stormwater infrastructure. 

We believe that working with what we have and not putting pressure on the systems in place is extremely important in creating effective Integrated Water Management Solutions.

Environmental Impacts

The environment impact that we can have through water management is not insignificant. Making sure that we are creating greener and cooler urban environments is extremely important in making sure that our environmental footprint is minimal.

We share the big missions of healthy streams and waterways, protecting aquatic life and keeping our beaches swimmable.

Helping the Client

InSite is able to help clarify how stormwater standards apply to your project, reducing the time it takes to receive approvals, and improving the design outcomes.
The building occupant also benefits by saving money and reducing portable water use, where rainwater is applied to fit-for-purpose practices, such as in toilets, hot water, laundry washing and garden irrigation.

InSite Water is designed and maintained by the team at Organica Engineering. We are an independent engineering consultancy specialising in partnering with other organisations on Integrated Water Management and other sustainability opportunities. We are based in Melbourne, Australia.
