English summary

Machine translated from Spanish by FreeTender. The original notice below is the binding text.

The object of the contract is the provision of the services of exploitation, conservation, maintenance and repairs of the wastewater treatment station of Villalonquejar, the withdrawal and management of the mud produced in the installation. The Adjudicator will therefore be solely responsible for the processes of depuration of the EDAR in its charge and the compliance with the conditions required in the authorization of dumping, as well as compliance with the implementing legislation in the application of sludge from urban wastewater purification in agriculture.

Details

El objeto del contrato, es la prestación de los servicios de explotación, conservación, mantenimiento y reparaciones de la estación depuradora de aguas residuales de Villalonquejar, la retirada y gestión de los lodos producidos en la instalación. El Adjudicatario será, por tanto, el único responsable de los procesos de depuración de la EDAR a su cargo y del cumplimiento de las condiciones exigidas en la autorización de vertido, así como del cumplimiento de la legislación de aplicación en cuanto a aplicación de lodos procedentes de depuración de aguas residuales urbanas en agricultura. Se incluyen en el contrato, como prestación diferenciada, los conceptos de "Grandes Reparaciones" e Inversión de adecuación inicial, debido a que, aun siendo servicios de mantenimiento, se pueden considerar inversión, y, por tanto, requieren una contabilidad independiente y un porcentaje de IVA, a aplicar diferenciado al resto del contrato de prestación de servicios.

  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
