Favourites - This allows you to create a quick link to any calc or tool you use often.
Water -
CL2 Gas feed - Calculate feed rate (g/hr) from plant flow (L/s) and mg/L dose, calculate dose rate (mg/L) from feed rate (kg/Day) and plant flow (L/s).
Solution Chem Feed - Calculate feed rate (ml/min & L/hr) from dose rate (mg/L) and plant flow (L/s), calculate dose rate (mg/L) from feed rate (ml/min) and plant flow (L/s).
Chloramination - Calculate Chloramination Ratio with any combination of the above calc's, ie gas-gas or gas-liquid or liquid-liquid.
Dry Chem Feed - Calculate amount of dry chemical (KG/Day & kg/hr) required for a certain dose rate (mg/L) and a certain plant flow (L/s)
Dosing Solutions - Preparation of dosing solutions, made from dry chems or liquid.
Jar Test Solutions - Calculate amount of chemical required for each jar during a jar test.
Detention/CT Times - Calculate detention times and CT times
Drop Test Timer - Timer for drop testing dosing pumps, with a data logger for recording test results for records. User is able to create a customized logger specific to their plant and email results for ease of data entry.
Meter Logger - User is able to create a log file to record specific meter and then email this information for ease of data entry.

Waste Water-
Total Suspended Solids - As the title says, total suspended solids calculator.
Total Dissolved Solids - As the title says, total dissolved solids calculator.

Maintenance -
Vol of Water in pipe - Calculate the volume of water in a length of pipe.
Water travel time in pipe - Calculate the time water takes to travel in a length of pipe.
Lost Water Calc - Calculate amount of lost water through a burst or other (approx flow and time required).
Flushing timer - A timer to calculate amount of water used during flushing, also allows user to create a data logger and record the approx amount of water through a hydrant. User can then email this data for ease of data input.

Dam Surveilance - Mainly used for timing and recording seepages for dam surveilance, allows user to create a data logger for piezo and seepage recording. This can be emailed for ease of data entry.
