Pumping and water treatment
Pumping is the operation used to extract water from rivers, water tables and reservoirs to route it to the treatment plants.
Treatment is carried out in 5 stages: pre-treatment (sifting), clarification (aggregation of the decantation of particles), filtration (elimination of the finer particles), refining (micro-elimination of pollutants), disinfection (elimination of viruses and bacteria.)
Storage and distribution
Reservoirs constitute a safety device in the event of problems in production, peaks in demand, or pollution of the resources.
The underground distribution network is checked to guarantee the stability of the quality of water and to control leaks.
Customer service
Specialised structures are in charge of ensuring contacts with consumers, taking into account the local situation: signing contracts, meter reading, billing, payments or accounts.
Collection of wastewater and purification
Sanitation networks play an essential role in controlling domestic pollution because they transfer all the wastewater to the sewage plant.
Wastewater treatment involves a series of complex biological processes.
Sludge
The treatment of one cubic metre of wastewater produces 350 to 450 grams of sludge. Sludge dehydration and treatment processes are used to reduce their volume. Most of the sludge is recycled for agricultural purposes as manure transformed into compost or recovered as energy.
