THE WATER CYCLE SANITATION Sanitation | Reclaiming | Co-generation THE WATER CYCLE SANITATION SANITATION Sanitation management comprises the transport of wastewater through the urban sewage network to the wastewater treatment stations (EDAR), its purification and its subsequent return to the rivers in optimum condition. For these purposes, Canal de Isabel II Gestión manages a complex system comprising: municipal sanitation and sewage networks (collectors and emissaries), wastewater pumping stations, storm tanks and wastewater treatment stations. URBAN SEWAGE NETWORKS The purpose of the urban sewage networks is to collect domestic and industrial wastewater and rainwater runoff for its subsequent transport to treatment stations. The company is in charge of the maintenance of such municipal networks, comprising 11,148 km, in all municipalities with which Canal de Isabel II Gestión has executed an agreement. It also manages 751 km of collectors and emissaries, involving a grand total of 11,899 km of major conducts distributed throughout the Madrid Region. WASTEWATER PUMPING STATIONS These facilities are necessary to elevate the waters where it is impossible to transpor them by the force of gravity. Pumping stations No. Municipal stations 77 No. Non-Municipal stations 48 Total no. 125 Installed capacity (kW/h) Maximum elevation capacity (m3/h) 7320 30,000 STORM TANKS The company currently manages 64 storm tanks and laminators, whose purpose is to prevent flooding and spillage to the rivers. These facilities allow to retain up to 1.46 million cubic metres of the first rainwater, the most polluting. Storms tanks and laminators 2 Total no. Volume (m3) 63 1.462.000 www.canalgestion.es THE WATER CYCLE SANITATION PURIFICATION Canal de Isabel II Gestión is in charge of wastewater purification for the whole of the Madrid Region. For this purpose, it has 154 wastewater treatment stations, with a nominal treatment capacity exceeding the equivalent of 17 million persons. The construction, exploitation and maintenance of wastewater treatment stations require plentiful technical, human and economic resources. The Madrid Region is currently one of the few regions able to assert that it purifies 100% of its wastewater.

company has a purified water laboratory, which places us in the vanguard of analysis techniques used to monitor the water sanitation process. The commissioning of the new laboratory has doubled our ability to control the quality of water purified in the Madrid Region, with an average of seven analyses per hour. The new laboratory allows an extension of this practice to control the quality of effluents purified in wastewater treatment stations (EDAR) and to monitor the quality of reclaimed water destined to the watering of green spaces. This laboratory is certified by ENAC to determine pH, conductivity, turbidity, free and total chlorine and suspended solids in reclaimed waters and also pH, conductivity, turbidity, suspended solids, DQO and DBO5 in wastewater. 10 www.canalgestion.es THE WATER CYCLE SANITATION RECLAIMED WATER In order to achieve the objective to reuse purified water set by Madrid’s Dpura scheme, 29 reclaimed water production facilities have been built, together with the city countil of Madrid, and Canal Gestion manages now more than 347 km of specific networks to facilitate its distribution to water public green spaces, hosing down of streets and industrial uses. Further, the company is currently responsible for the water reuse system of the city of Madrid, where it counts with specific areas and distribution infrastructure for the refill of cleaning and watering vehicles with reclaimed water. CO-GENERATION The company owns certain facilities which, synergistically with the sanitation processes, allow generating renewable energy, using the sub products of the different processes for energy and the co-generation of electricity. For these purposes, it owns 11 electricity generation plants fuelled by biogas produced in the wastewater treatment facilities’ processes, a cogeneration plant associated with the thermal drying process applied to mud and with small changes of height in wastewater. As a result, Canal de Isabel II Gestión has the greatest stored capacity for the production of electrical energy of any company within the Madrid Region (a total of 82.05 megawatts). 11 www.canalgestion.es Santa Engracia, 125 28003 Madrid 900 365 365 www.canalgestion.es
