Network Assessment

Dataloggers are used to monitor and store parameters in the water supply and distribution network. They have the facility to communicate these parameters to a central or remote data collection unit so that trends can be observed.

These include flow, water pressure, level, and water quality (e.g. chlorine, PH, & turbidity).

Pressure can be used to ensure that statuary pressure is being met and also for hydraulic modeling and calibration.

Flow is used to determine consumption, either from consumers or supply to a particular part of the network. Knowing network supply and consumer consumption, water loss in the distribution network can be calculated. Flow changes over time can also indicate water loss. Flow is also used to size meters.

The Total Integrated Flow (or Water Balance) Method is a useful means of assessing the overall leakage performance for a system on an annual basis. It will take into account all leakage from the system, including that from reservoirs and trunk mains, and can be carried out based on data which all Water Suppliers require, not just for leakage control, but for forward planning and financial management. However, the errors inherent in the data used make the absolute accuracy of the calculation questionable. Also, it can take some time (e.g. a month or two) to assemble and compute.
