Sigma is a benchmarking and performance indicators software for drinking water and wastewater utilities. The software is based on the IWA system of performance indicators and its Lite version is the official software for such system. Sigma makes the definition of a performance indicators system and the management of results an easy task.

Performance indicators are a powerful tool to manage water utilities. Sigma Lite is a freeware package based on a proposed set of performance indicators by the International Water Association. Sigma guides the user through the process of selecting and implementing a system of indicators for the utility. Sigma Lite was officially released in July 2000, as part IWAP Manual of Best Practice and “Performance Indicators for Water Suppy Services”.

Although Sigma is the official software for IWA indicators, this will not limit your possibilities of selecting the best ratios for your project. The software offers you additional predefined sets to select from and allows creating new indicators from scratch. And all this within the IWA framework, guaranteeing the scalability of your system and preserving the chance of comparison with international references.

Working with indicators does not necessarily mean to have a colored spreadsheet. Sigma’s user interface has been completely redesigned to create an intuitive experience. Our integrated help system will assist you directly in each screen so you do not need to constantly look at the manual.

Sigma has been designed to enhance your productivity. Whether you are managing a benchmarking project with dozens of participants, or you are in charge of collecting indicator data for your company, Sigma will make things easy for you. Our years of experience will make each one of the steps in the way, from data collection to results publication a simple and quick task.

Sigma is a performance indicators software that can be used in any field. However, if you are in the water or wastewater business you will find many additional reasons to use it. Sigma helps you to create your PI system with the indicators defined by the International Water Association. A great starting point to help you succeed with your indicators project.
