Cost: $2.99

Designed for both water and wastewater system operators, this NRWA app includes a variety of calculators for common treatment plant activities.  The list includes, but is not limited to: pressure conversion, flow conversion, chlorine demand, feed pump sizing, filtration rate, and calculations related to chemical feed, dosing, and pipe/tank/well disinfections.


Pipe Diameter Calculator
Developer: pipeflowcalculations.com
Platforms: Android 1.5 and up
Cost: Free

Need to calculate a pipe diameter?  Many downloads and reviews suggest that this app is as guick and easy as it claims.  Enter the desired stream flow velocity and known volume or mass flow rate, and the app will calculate the proper internal diameter requirements for round pipe.  Conversely, run and check on stream velocity by entering the known internal pipe diameter and flow rate.


Process Water Products
Developer: Thermo Fisher Scientific
Platforms: iOS 4.3 or later
Cost: Free

Not sure what product will do the job?  This app makes it easy to find the product that matches each individual application need, including pure water analysis, power plant water analysis, drinking water analysis, wastewater analysis, pulp and paper manufacturing, and general processing.


ProTek Water Calc
Developer: ProTekMobile
Platforms: Android 2.2 and up
Cost: Free

ProTeck Water Pro is another calculation app, but it’s notable and included on the list for its everything-and-the-kitchen-sink scope.  Suitable for both water utility professionals and engineers, it can calculate pump power, flow rate, head and efficiency; flow rates for full-pipe open-discharge and open-channel rectangular weirs; water loss for three different types of water line breaks (holes, cracks, and circular breaks); and all the common formulas and unit conversions, in either US or SI units.  It also includes “disinfection estimators” for tanks and pipelines.


SAM-1 Smart Aqua Meter
Developer: Sensorex
Platforms: IOS, Android
Cost: FREE

This app turns smart devices into pH, oxidation-reduction potential (ORP), conductivity/total dissolved solids (TDS), and temperature measuring meters that not only measure, but also communicate collected data via instant and error-free email.  Users can simply plug the SAM-1 into the audio jack of their smartphone or tablet then plug in the smart sensor to take accurate readings.  Samples can be measured in the lab, field or plant and the readings can be shared via email.


Sewer Design Calculator
Developer: Transparent Blue
Platforms: Requires Android 1.6 and up
Cost: $1.89

This app is designed for those involved in building or maintaining sewer infrastructure.  The app uses “The Manning Equation” to calculate the necessary pipe diameter and slope for a given project.  The user inputs the desired flow, length, initial ground elevation, and final ground elevation, and the app uses this data to calculate the slope, diameter, depth and tractive force needed.  The user has the option of working in U.S. units or SI units.


Tank Level Monitor
Developer: G-Ware
Platforms: Android 1.5 and up
Cost: $ .99

Keep track of critical tank levels with this app.  Simply input starting levels and feed rate, and the app will calculate the current tank level every 60 seconds.  The app is designed to monitor a variety of chemicals including peroxide, caustic soda, fluoride, hypochlorite, sulfuric acid, and ethylene, and will display both starting level and current level for each substance.  A low level alert will appear when any thank is at or below low level setpoint and allow the user to update the levels when a tank is filled.  The app can be used to monitor multiple tanks.  Each tank’s level can be emailed to anyone directly from the app.  Designed for large and small water and wastewater treatment plants.


Trimble Connect
(https://itunes.apple.com/us/app/trimble-connect/id730406198) or
