Water Knowledge

Group of happy members


To effectively operate in the water industry, and to make sustained positive contributions, we have to continuously educate ourselves on the various aspects of the water cycle right from the sources of water, to its extraction, purification, distribution, effluent treatment and disposal. Intermingled between these processes are other factors such as infrastructure management, emergency preparedness, and protection and conservation of water.

AWWA has compiled informative literature on some of the above-mentioned aspects which help us to know more about our water systems and ways to improve its quality and delivery parameters.

Water Loss Control

Corrosivity Calculations

Estimate the corrosivity of a water sample using the Langelier Saturation Index (LSI) and the Ryznar Stability Index (RSI); the following spreadsheet comes from AWWA WaterMATH version 2.0 (currently unpublished):
