Eco.SWM is a tool to calculate the so-called "Net present value" (Life Cycle Costs) for different scenarios in water management. This version is a standalone version and includes a sample file. In the database unit prices, operational cost per unit and lifetime expectations for many different measures can be stored.

We announce the release of an improved version of Eco.SWM for March 3, 2008. From this time on, the old version 2.1 will not work with the web-database any more.

The new version offers the following:
- support for negative costs (i.e. for subsidies),
- improved user-interface
- improved web-access.
