WATER & WASTE MANAGEMENT, part of MultiEducator's "Formulator" line, is the essential tool for any Water & Waste Management engineer or engineering student. This comprehensive application contains over 245 specialized engineering formulas covering all major areas of water and wastewater engineering, plus nearly 900 conversion formulas — over 1,100 formulas in total. Engineering categories include: Water Flow, Groundwater, Sewage Treatment, Pollution, Activated Sludge & Sludge Digestion, Water Supply, Facilities (Chemical Dosing, Distribution, Disinfection & Laboratory), Storm Runoff, Sewer Pipe, Waste (Gases, Liquid & Solid), River Pollution, Hydraulics (Hazen-Williams, Darcy-Weisbach, Bernoulli), Pumping (Horsepower, NPSH, Affinity Laws), Water Treatment (Chlorine Dosage, CT Values, Chemical Feed Rates, Filtration), and Wastewater Operations (BOD Loading, SVI, F/M Ratio, MCRT, Detention Time, Removal Efficiency). The app also includes conversion calculators for Area & Volume, Pressures, Linear Measure, Weights, Liquid Measures, Cubic Measures, BTU, Horsepower, Watts, Power, Hydraulic, HVAC, Flows, and over 460 Metric conversions — plus eight temperature scale converters. All formulas display results in both US and Metric units with a single toggle. Calculations can be saved, exported, and shared. Toggle between US and Metric units instantly. If you need a formula we haven't included, just email us and we'll add it in the next update.

I work in this area so I thought why not.... I bought your $10 arch app to help with water treatment day to day stuff and I find it just as usefull as this app. I can think of at least 15 more formulas that we deal with on a daily basis. I would gladly email you those formulas but it would take me all day. Its not a bad idea but if you are gonna charge us $5 then you need to put some effort into your apps. A simple google search located me 7 formulas that are not in this app. I have spent alot if money on this devolopers apps and they all are made with great potential but all fail. Put some more love and care into your apps and we will gladly pay a little more as well.

Terrible app.

I must agree with the previous poster. This app is worthless. I, too work in this area and find that the formulas are not only worthless, but also cumbersome to operate. I can't believe I paid $5 for it and was excited to pay it. Huge disappointment!!!
