The contract is mixed, with services as the main component and accessory construction works for punctual maintenance, conservation or improvement of the network. The scope covers preventive, corrective, extraordinary and emergency maintenance of the municipal sewer network; inspection and diagnosis of asset condition; advanced and selective cleaning of collectors, branches and capture elements; maintenance of critical and singular points; actions on pumping stations, overflow structures and DSS (in the municipal low-voltage network, where applicable); updating of the inventory and mapping (GIS); technical support to municipal management; punctual conservation works; and municipal connections or related works required by the Council.

The initial term is 2 years, with expected start on 1 March 2027, and there are two optional one-year extensions. Special environmental conditions apply (documented and traceable waste management through authorised managers, and environmental badges for vehicles where technically compatible, including Low Emission Zone restrictions). Special social conditions apply (reinforced health and safety measures for confined spaces, public roads, biological risk and emergencies, and compliance with the sector collective agreement). The estimated contract value is EUR 1,274,568.40 excluding VAT (the tender base budget is EUR 637,284.20 excluding VAT, or EUR 741,432.24 including VAT).
