WATER LOSS REDUCTION THROUGH ON-LINE MONITORING OF PHYSICAL AND CHEMICAL PARAMETERS

Abstract

The water distribution network is the most expensive water supply system of populated centers (50-70% of the total cost of installation), due both to its large length (1-2 m / inhabitant) and the fact that currently, the networks have been made largely of steel tubes and azbo-cement. Intermittent operation is not recommended in drinking water system due to the danger of water contamination, due to lower atmospheric pressure in the pipes under pressure during their discharge with the entrance of the dirt from outside the pipe. The cabinets are installed in distribution network nodes. The devices supervise continuously and transmit to the central dispatch, on-line the following parameters: pressure, pH, conductivity, temperature, turbidity, water flow. All information is stored and generates reports and charts with the evolution of the parameters registered.
