DRAINS, PIPES & PIPES++
We design, develop and support Australia's leading modelling and analysis software for stormwater and drainage systems.
Australian-owned and operated since 1998.
Developed and supported locally in Australia, DRAINS allows users to design and analyse stormwater drainage systems, produce summary graphs and tables, and create pipe long-section drawings.
DRAINS incorporates the latest Australian Rainfall and Runoff (AR&R) guidelines.
First software to incorporate AR&R Design Procedures & BOM 2016 IFDs (January 2017)
First software to incorporate the new Australian Rainfall and Runoff (AR&R) design procedures.
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.
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.
All DRAINS licences include the Australian Rainfall and Runoffs’ (AR&R) Initial Loss – Continuing Loss (IL-CL) and Horton (ILSAX) hydrological models, and are capable of analysing AR&R temporal patterns and design procedures.
Note: When referred to below, a “link” is a pipe, channel, pump, orifice link or weir link.
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.
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.
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.
DRAINS comes with 12 months of updates and support. Ongoing updates and support are available if required after that time. If your updates and support have expired, you can request a quote here.
Workshops on DRAINS are presented by Kustom Engineering. Public workshops are currently on hold due to COVID-19. As an alternative, live webinars have been presented since March 2020 and online E-Learning since August 2020. Please see Kustom Engineering for more details.
