RainCycle Rainwater Harvesting Software Now Available for FREE Download
In March 2009 we took the decision to allow FREE distribution of RainCycle, our flagship software application. RainCycle is a state-of-the-art computer simulation of rainwater harvesting systems and can be used to assess the water and cost saving potential of these devices. It is applicable to most types of modern systems such as those typically installed in residential, commercial and institutional buildings. RainCycle has been used in several academic research projects and has been the subject of a peer-reviewed paper. Visit the Freeware Section in order to download the software.


July 2008

Rainwater Harvesting PhD Thesis
Our managing director has recently completed a PhD entitled "A Whole Life Costing Approach for Rainwater Harvesting Systems". Not only is this an important contribution to the field, it will also be of use to anyone interested in or researching the topic. The thesis presents a thorough overview of contemporary rainwater harvesting as well as detailed chapters on modelling approaches, optimising storage tank size, assessment of system performance, operation/maintenance issues and financial analysis. Hundreds of references and extensive data sets make the thesis an invaluable source of information.

June 2006

Freeware Section Unveiled
As part of our continuing commitment to promoting the use of sustainable drainage techniques, we have chosen to make some of our own in-house applications available for download free of charge. See the new Freeware Section for further details.


November 2005

RainCycle v2.0 Launched
RainCycle is a state-of-the-art rainwater harvesting hydraulic and whole life costing assessment tool. It is the product of several years of active research in the fields of sustainable water management / sustainable drainage systems. In response to feedback provided by industry and clients RainCycle has undergone a major upgrade. RainCycle v2.0 retains all the functionality of previous versions and now also includes the following features:

  • User-definable analysis period of between 2-100 years
  • Monte Carlo simulation for comprehensive risk and uncertainty analysis
  • Greater flexibility in the types of systems that can be modelled
  • Two types of automatically generated reports available: basic and full
  • Ability to change currency type: $, £, € or “user-defined”
  • Improved interface: easier to use and enhanced support
  • Complies with current UK best practice guidance

Click here for a full list of features.

Further, each RainCycle license now comes with two copies of the application: RainCycle Advanced© and RainCycle Standard©. The Advanced edition is the full version of the application whilst the Standard edition is a simplified version more suited to performing quick assessments e.g. for feasibility purposes or if a client does not require a detailed study. RainCycle represents the most comprehensive hydraulic and financial assessment commercially available for rainwater harvesting systems. The table below shows a comparison between the widely used “rule-of-thumb” approaches and RainCycle.

RainCycle is also the subject of a recent conference paper. Click here for further details.


April 2005

RainCycle v1.0 Launched
RainCycle is a powerful spreadsheet-based rainwater harvesting simulation program. Its key features include:

  • Hydraulic simulation of rainwater harvesting systems and associated water fluxes
  • Whole-life costing analysis (capital, maintenance/operation and decommissioning costs)
  • Scenario modelling - capable of modelling thousands of system variations for any given design
  • Built-in tank size optimisation and sensitivity analysis routines
  • Easy to use and attractive user-interface
  • Automatically generates reports for modelled systems
