DRAINS: Australia's leading Stormwater Drainage System design and analysis software.

Developed and supported locally, DRAINS is Australia’s most trusted and widely-accepted modelling and analysis software for stormwater and drainage systems.

Celebrating its 25th year, DRAINS allows users to design and analyse stormwater drainage systems, produce summary graphs and tables, and create pipe long-section drawings.

DRAINS also incorporates the latest Australian Rainfall and Runoff (AR&R) guidelines.

  • Draw drainage system components such as sub-catchments, pits, pipes, detention basins, channels and overflow routes.
  • Use several available hydrological models recommended by the AR&R guidelines.
  • Solve the full unsteady flow equations in pipes, channels and overflow routes.

First software to incorporate AR&R Design Procedures & BOM 2016 IFDs (January 2017)

Features

AR&R Compliant

First software to incorporate the new Australian Rainfall and Runoff (AR&R) design procedures.

Hydrology

Use IL-CL (the AR&R preferred model), Horton ILSAX, Rational & Extended Rational Method models, and a Storage Network Routing Module that includes RORB, RAFTS and WBNM.

Hydraulics

Solve the full unsteady flow equations, which is useful for analysing complex surface flooding situations where storage or backwater effects occur in overflow routes, or when splitting surface flows in multiple directions.

Licensing Options

DRAINS is available as a Subscription or USB Perpetual licence in multiple configurations.

All new DRAINS licences include the Australian Rainfall and Runoffs’ (AR&R) Initial Loss – Continuing Loss (IL-CL), Horton (ILSAX) and Rational & Extended Rational Method hydrological models, and are capable of analysing AR&R temporal patterns and design procedures.

All DRAINS licences also include the Full Unsteady Hydraulic Model, Storage Network Routing Models (RORB, RAFTS & WBNM hydrological models) and the GIS Module.

Note: When referred to below, a “link” is a pipe, channel, pump, orifice link or weir link.

Demo

The demo version of DRAINS (available to download here) is fully functional software, except that it is limited to a maximum of five pipes or channels, one irregular channel and limited to viewing existing detention basin data only. 

DRAINS

DRAINS solves the full unsteady flow equations in pipes, channels and overflow routes. DRAINS is available in Standalone Subscription 5, 20, 50 or unlimited link versions, Network Subscription Unlimited links, or USB Perpetual Standalone and Network Unlimited Links versions.

  • Solving the full unsteady flow equations is useful for analysing complex surface flooding situations where storage or backwater effects occur in overflow routes, or when splitting surface flows in multiple directions via multiple outgoing overflow routes.
  • Pumps, weirs and orifices can be modelled as separate objects allowing for complex arrangements (e.g. multi-level orifice outlets from detention basins or pit diversion chambers, or overland flow diversions across the crown of a road).
  • It also includes a flood mapping capability.
  • A USB Network version of DRAINS allows the licensed number of users access to DRAINS from anywhere on your network in a single region, while the Network Subscription provides unrestricted global access with minimal IT requirements.

DRAINS Viewer

The free DRAINS Viewer allows anyone to open DRAINS files and inspect the model structure, inputs and results. The Viewer operates in the same way as DRAINS, but does not allow models to be altered or run.

  • If a DRAINS .drn file contains stored results, these can also be viewed, and exported to spreadsheets.
  • The purpose of the Viewer is to make checking or reviewing of DRAINS models easier, either within an organisation, or between organisations such as a consultant preparing a model and a Council reviewing this.
  • The Viewer can be freely distributed by DRAINS users to other organisations.
  • The Viewer will need to be periodically updated when the DRAINS .drn format alters, otherwise it will not be able to view files created with the latest version of DRAINS.

Included Modules

Three additional modules are included with new DRAINS licences.

Storage Network Routing Module

The Storage Network Routing Module adds the RORB, RAFTS and WBNM storage routing hydrological models, useful when modelling large urban or rural sub-catchment areas where estimating the time of concentration with time area routing might be difficult.

DRAINS RAFTS does not rely on XP Rafts and is not affected by the discontinuation of XP Rafts by Innovyze.

GIS Module

The GIS Module is useful where you need to interface with GIS systems that support ESRI shapefiles or Mapinfo MID/MIF files. This module allows transfer of data and results between DRAINS and GIS.

Rational + Extended Rational Method Hydrological Module

The Rational + Extended Rational Method Hydrological Module adds the ability to model the rational method procedures with ARR87, ARR2019 and AS3500.3.

The Extended Rational Method allows users to produce hydrographs to improve detention basin analysis and utilise the full unsteady hydraulic model. This is achieved by including temporal patterns as part of the analysis and including the ability to model ensembles of storms from ARR2019.

Maintenance & Support

All DRAINS subscriptions include ongoing maintenance and support. For perpetual licences, maintenance is renewable every 12 months. If your maintenance has expired, please read this important policy update and request a quote for renewal.
