The company will award two contracts associated with wastewater treatment in the Autonomous Community of Madrid. Engines and electrical installations will be automated at eight WWTPs to reduce energy consumption and 43 million euro will be allocated to the operation of the Butarque and Valdebebas Wastewater Treatment Plants (WWTP), with a view to reducing annual CO2 emissions by 4,000 tonnes.
The Governing Board of the Autonomous Community of Madrid was today informed of Canal de Isabel II’s proposals to award the two contracts. The first is for the operation and maintenance of the Butarque and Valdebebas WWTPs, while the second is for the supply of enhancements to energy efficiency at a further eight wastewater treatment plants. Both proposals are subject to approval by the executive board of the publicly-owned company.
The first contract relates to operation and maintenance services at the Butarque and Valdebebas WWTPs. The contract, divided into two independent lots corresponding to each of the infrastructures, is worth a total of 42,887,208 euro, excluding VAT, and has a duration of five years. Both the Butarque WWTP and the Valdebebas WWTP are located within the municipal district of Madrid and are owned by Madrid City Council. Since 2006, the management of these infrastructures and other WWTPs belonging to the Council has been the responsibility of Canal de Isabel II. The Butarque WWTP, which belongs to the Manzanares river basin district, was built in 1982 and has the capacity to remove the pollutant load of a population equivalent of over 1,600,000. The Valdebebas facility belongs to the Jarama river basin district. Also built in 1982, and extended in 2000, it can treat the pollutant load of a population equivalent of over 250,000.
This new contract consolidates the company’s renewed commitment to the circular economy and seeks to transform the largest possible proportion of the waste contained in wastewater into resources of value. Both plants are capable of producing up to 18 million KWh per annum of power from the pollution they receive, sufficient electricity to supply a population of over 14,000 (San Agustín or Meco), whilst also preventing annual CO2 emissions of almost 4 million kg.
The second contract relates to the supply of energy-efficiency enhancements at Canal de Isabel II wastewater treatment plants. The contract has a budget of 2,960,286 euro and a duration of two years.
The enhancement projects will mainly be carried out at eight WWTPs: La Gavia; Sur Oriental; Arroyo Culebro Cuenca Alta; Arroyo Culebro Cuenca Baja; Arroyo de la Vega, Galapagar – Torrelodones, El Endrinal and Tres Cantos. The initiative envisages the automation of engines and electrical installations to enable a 10 % reduction in power consumption.
STRATEGIC PLAN: COMMITMENT TO CUSTOMERS AND USERS
This initiative forms part of Line 4 of the Canal de Isabel II Strategic Plan 2018-2030 to promote environmental quality. It includes the plan for excellence in wastewater treatment, which seeks to improve the quality of discharges from WWTPs and contribute to the good status of rivers in the region, and it also encompasses reducing the energy consumption and carbon footprint associated with the activity of the organisation.
