FlowCalc for iOSWhile on the go, the FlowCalc offers you all the functionality you need to quickly calculate flow rates, pipe diameter and velocity on your mobile device.

GeoPro – Work Alone Safety System – GeoPro is an employee check-in and safety alert monitoring solution that makes it easy to protect employees working alone.

Pipe Diameter Calculator – Android – This calculator is designed for simple and quick calculation of round pipe internal diameter based on known volume or mass flow rate and desired stream velocity through pipe.

McWane Pocket Engineer™ – This application allows users to retrieve pertinent technical information on products through its automatic calculators. Users can have access to calculations that are essential in the field, and would otherwise take valuable time to compute.

PlutoCalc App for iOS and AndroidA free problem solver suite for water treatment, wastewater, hydraulics, environmental chemistry and unit conversions.


CUPSS – The Check Up Program for Small SystemsCUPSS 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.
