The Paiporta City Council has presented the Municipal Hydraulic Infrastructure Reconstruction Plan, an unprecedented intervention that will comprehensively renovate the municipal sewer system damaged by DANA, with an investment of over 90 million euros.

The Paiporta City Council held an open informational session for citizens to explain the details of the Municipal Hydraulic Infrastructure Reconstruction Plan affected by DANA. The session, led by the technical team from the DANA Special Projects Unit (UNPE DANA) of Global Omnium, the company managing Paiporta's integral water cycle, served to resolve doubts and introduce an action that will involve the comprehensive renovation of the municipality's sewer network.
Technicians from UNPE DANA emphasized that this is an unprecedented intervention in Spain, as it will simultaneously reconstruct an urban network that was 100% affected during the October 2024 DANA. They highlighted that having a prior master plan for the sanitation network allowed for a quick and precise diagnosis, and that the project will equip Paiporta with a modern sanitation system.
The mayor of Paiporta, Vicent Ciscar, explained the significance of a project representing one of the most important investments in the municipality's recent history. He valued the coordination between administrations and the technical effort to adapt projects to real needs. For her part, the deputy mayor and councilor for Reconstruction, Marian Val, highlighted the complexity of the planning and stressed that the works will be designed to minimize inconvenience to citizens.
If the planned deadlines are met, works could begin in October. They will be carried out simultaneously on three fronts, with constant coordination between the contracting companies, the City Council, and the Local Police. No water supply cuts are expected, except for occasional interventions.
Paiporta's sewer network, spanning 78.33 kilometers, was affected in its entirety. 22.46 kilometers (28.67%) will be reconstructed over an estimated period of 48 months. The total investment amounts to 90,670,270 euros, with subsidies from the Ministry for Ecological Transition and the Ministry of Territorial Policy. The goal is to transform the damaged infrastructure into a modern, resilient network adapted to sustainability and climate change.
The works have been divided into three parallel lots to accelerate progress in urban, industrial, and residential areas. They will include the replacement of manholes, renovation of domestic connections, improvement of drains, and reconstruction of the network. Additionally, structural improvements will be incorporated, such as the drainage system, adaptation to overflow regulations, new pollutant control elements, five anti-pollution tanks, an inflatable park, and a green drainage channel.
The tender for the works was published on April 25, 2026, in the BOE and the DOUE, with a deadline for offers on May 25. More than 25 companies have shown interest, and bids are currently under evaluation, with adjudication expected around June 20. The City Council and Global Omnium have previously worked on planning and coordination.
This strategic sewer reconstruction project will not only repair flood damage but also equip Paiporta with a more efficient, secure sanitation network prepared for the challenges of climate change, becoming a benchmark for future hydraulic reconstruction interventions in Spain.
