Sectorization

Sectorization of the Hydraulic Networks allow us to reduce the amount of unregistered water, improving hydraulic output and control of criteria which affects water quality.

Sectorizing a network consists in dividing it into isolated sectors to analyze them separately, and in this way facilitate the identification of problems, improving the speed at which we can apply correct repair methods. All sectors must be conveniently equipped with meters, pressure transductors, chemical indication measuring devices, regulating valves, registers etc.

Sectorization and design of the sectors in each area requires the use of the Geographic Information System (GIS), Mathematical models of the network as well as the details of the Client Management System, because it must never affect the quality of the service.

In each sector necessary hydraulic works are carried out to isolate it from the rest of the network, and necessary control elements are installed to monitor its behaviour: measuring devices and flow/pressure registers, regulatory pressure valves, residual chlorine measurers etc.

Of all registered information we dispose of an immediate way of analyzing it, this allowing for fast decision making and action. For this necessary communication is installed to send data to the Control Centres.

The fundamental objective of sectorization is to dispose of enough distributed information on a manageable scale to:

• Carry out audits to know the hydraulic efficiency or non registered water.
• Characterize the demand curve, especially for nocturnal flow.
• Quickly detect possible leaks analyzing the evolution of nocturnal flow.
• Quickly checking the results of search campaigns and leak repair.
• Detect fraud, undercounting or other measuring errors.
• Lower maintenance costs.
• Plan inversions to orientate action to sectors with the most non registered water.

All registered information is immediately available for analysis, which is the reason why we install necessary communications for sending data to the Control Centre, where all information from the instrumentation of each sector is received and processed. From the Control Centre priorities are established for the maintenance teams, thus allowing us to significantly reduce the amount of water lost via a reduction of time that it is leaking, and ensuring that the water remains of drinking quality.

This management model, based on the sectorization of the networks, allows us in medium term to significantly reduce costs and above all save a great amount of a resource which is scarce and necessary, such as water.
