InSite Testimonials

"InSite makes my work easier"

"InSite is a complete and comprehensive modelling package providing sustainable options for meeting Local Authorities detention and Storm Score requirements for development sites.

InSite makes my work easier because it is a simple to follow modelling package with two main steps involved (site details and modelling inputs) and the outputs summary makes checking of consultants' drainage inputs fairly easy.

I have constantly promoted InSite Water as it is a comprehensive modelling package that provides options for providing detention. It’s a complete package for Sustainable Water tank Detention, addresses OSD4 requirements for storage and flow rate and provides a STORM quality score which means it’s an all in one package. There is no need to have separate packages for OSD4, Melbourne Water STORM score and a water tanks solution package."

Joe Cusmano

Sustainable Development Engineer - Knox City Council


"The best thing about InSite is the level of detail that can be modelled."

"The 4 key Integrated Water Management (IWM) areas are broken down into their own sections, and the ability to make informed decisions and design choices from this information is invaluable.

InSite’s wide range of scale and building functions has helped alleviate a lot of the guessing, without needing to be on site, or waiting for building managers to come back with plans or setups. Another equally important feature, is InSite’s function of predicting rainfall yield within a location. This saves a lot of manual calculations and time.

InSite is a fantastic tool for engineers and consultants that design small scale systems for rainwater harvesting, that covers the 4 main IWM areas requested by councils. The level of detail and information provided is very valuable compared to the small fee charged for a professional license. Further, for the subscribing councils, it is a huge advantage for applicant engineers to make as many reports as required, without paying anything themselves."

"This kind of approach is the way forward for stormwater management"

"This is a common sense approach to site stormwater management. It is the way forward for consistent and positive outcomes for all parties.

Insite combines stormwater quantity and quality into the one package making the interplay between the 2 outcomes easy to manipulate.

I would recommend Insite to all Councils as the first step in overcoming the confusing and often contradictory approaches Council's have to site stormwater management.

"I wish you could persuade more Councils to get on board with InSite"

"InSite is an easy program to use for residential developments.

Obtaining an equivalent Storm score for multi unit developments using InSite is usually simpler and also cheaper for construction costs.

I would recommend every council get on board and make InSite a standard option alongside STORM and MUSIC. Having more tools to achieve the same goal would be great."

Does InSite use the Swinburne Method for OSD tank sizing?

InSite provides an option of Swinburne Method or the rational method (Boyd's triangular hydrograph equation) for sizing On Site Detention (OSD) tanks.

What council areas does the software cover?

The software has built in data for most of Australia's urban Councils.  If your Council is not included or you would like us to set up for and international area please contact us.

Please note that South Australia has developed their own localised version of InSite available here.

What are the limits of the software?

Does the software incorporate AR&R 2019?

The software is based on the Source Control and volume management recommendations of the Australian Rainfall and Runoff Guide 2019 book 9 - the Urban Chapter.

Can I save my work?

Yes, you can save your projects online in the website and come back to edit them later
