The supply phase begins with the Water Capture Process. The water that has fallen in the form of rain, snow or hail upon the surface area of the water catchment area is collected naturally. Thanks to the runoff and filtration processes, the water reaches the reservoirs where it is stored and regulated.
After it reaches the Drinking Water Treatment Plants, the naturally collected water is subjected to a number of processes to eliminate all of those elements that might prove harmful to consumers.
Regulating the flow of the untreated water and proportioning reactants
The purification process begins with the controlled entry of the untreated water into the plant. This phase is controlled using a level regulating valve. The rate at which the untreated water flows is controlled using a series of fixed section sluices that enable the flow to be regulated in accordance with plant requirements. Next, using a rapid action agitator, the corresponding reactants are added to the water, thereby preparing it for the following phases.
The water leaving the agitator is now subjected to a process of flocculation and coalescence, with flocs being created by the action of the reactants used.
Next, the floc-charged water is slowly sent around the settling tanks, thereby allowing the flocs to gradually sink to the bottom of the containers where they form a layer of sludge.
Later, and on a regular basis, this sludge is itself treated before being suitably disposed of.
The water is channelled to the filtration plant, passing through a sand-bed that retains any particles not eliminated during the settling process on the way.
the water is subjected to a final chlorination in order to ensure that it remains charged with residual chlorine throughout its journey around the supply line network.
During the water treatment process, a significant volume of sludge is generated, and this has to be conditioned and treated in a suitable manner. The final step will be to transport it for disposal in an authorised dry sludge disposal site.
Research is currently being carried out into how this sludge can be reused and/or recycled.

The drinking water is channelled to the points of consumption via an extensive network of tunnels and pipelines, either using the force of gravity or the intervention of pumping stations and/or other types of infrastructure.
The drinking water is delivered to the consumers via the Associated Municipal Councils. They are responsible for distributing it to the industrial clients and other end users.
All of the previously described processes are subjected to an exhaustive series of controls. Not only the information regarding the main quality parameters of the water (turbidity, residual chlorine, temperature and PH), but also that with respect to other variables affecting the operation of the network (flow, pressure, volume, etc.), is gathered by the peripheral stations and automatically transmitted (by radio and telephone) in real time to the Monitoring Centre.
From the Monitoring Centre it is possible to remotely control the opening and closing of the main valves that form part of the supply system network
