Building the Capacity of Drinking Water Systems

Interactive Tools for Owners and Operators

Asset management is the practice of managing infrastructure capital assets to minimize the total cost of owning and operating them, while delivering the service level customers desire. This management framework has been widely adopted by the water sector as a means to pursue and achieve sustainable infrastructure.

The following tools explain the benefits of asset management and ways to implement specific asset management practices for small systems.

Interactive Tools for Owners and Operators

Asset Management: A Handbook

Asset Management: A Handbook for Small Public Water Systems – STEP Guide Series (PDF) (EPA 816-R-03-016) This guide is designed for owners and operators of small community water systems (CWSs). CWSs include all systems (both publicly and privately owned) with at least 25 year-round residential customers or 15 year-round service connections.


The Check Up Program for Small Systems (CUPSS)
CUPSS is a legacy software application that was developed more than 10 years ago to assist drinking water and wastewater utilities in implementing an asset management plan. CUPSS was developed to run on Windows XP. Some users have reported challenges and compatible issues while trying to work with CUPSS in Windows 7, 8, and 10 operating systems. While still available for use, the tool is no longer being updated and may not compatible with the latest computer operating systems.
