ELEMENTS OF THE SANITATION PROCESS
URBAN DRAINAGE NETWORK
We manage a unitary network of municipal and supramunicipal collectors and emissaries and pipelines that collect and transport wastewater from the municipalities to the WWTP. Other facilities that complete the system are WWPS, whose mission is to raise wastewater at points where its transport cannot be carried out by gravity. In addition, we have storm water tanks that are intended to retain the first rainwater, which are the most polluting, minimizing the discharge of contaminated water and flooding.
Storm water tanks
Storm water tanks are large underground reservoirs that store initial rainwater to prevent waste water treatment plants from exceeding their capacity and discharging untreated excess into waterways. Canal de Isabel II manages over 70 storm tanks with a total capacity of more than 1.40 hm³. The Arroyofresno waste tank, with a capacity of 400,000 m³, is one of the largest in the world.
