Cloud based

The software means increased efficiency providing design resources you need when you need it, allowing you to deploy the same design capability consistently, with the same consistency in results every time.


Application selection ensure designers are able to get quick and accurate guidance in selection of the most suitable products based on the type of application the catchment is to cater for.

Flexible catchment design

QuAD is design to support designers in the creation of catchment areas. Supplementary catchment areas can easily be added upstream and downstream of any previously designed channel run.

Rainfall assist

Rainfall intensity by location matters in design. QuAD provides a site locator map enabling the most accurate intensity to be input.

Product optimiser

Optimising the specific channel runs can be done with the optimiser feature selecting the smallest product suitable. Excavation and concrete requirements are also provided.

Resilience assessment

By inputting anticipated sedimentation rates and sedimentation density the QuAD software enables the designer to test their suggested maintenance schedules.

Attenuation assessments

Calculate the attenuation required for the project and compare it with the storage available in the channel design. Attenuation volume is presented along with suitable options for storage.

Secure scheme filing

All designs created by registered users are stored on a secure server and are password protected. Past projects are easily retrieved from the personalised menu.

Flexible download format

Output can be generated for all or parts of the project and can be generated in pdf or CSV formats.

Knowledge database

There is support available either through a query submission or through self-help made possible by the comprehensive Knowledge database.

User Confidentiality

Maintaining confidentiality is crucial for our QuAD users and their projects. This is made possible by password protection. All users that included an optional password when they first registered on the ACO website will be able to access the software using the same details. For those that did not enter the optional password it is necessary to create one in order to be able to use the software; this is simply in order to ensure your saved designs are protected. The software does enable you to share designs for consultation either through email or through the creation of summary documentation.
