Las Palmas de Gran Canaria Launches Project for Renewal of Wastewater Collector
Project Overview
The Las Palmas de Gran Canaria City Council has opened a tender for the renewal of the wastewater collector located on Camino a Casa Ayala, in the Tenoya neighbourhood. The aim is to address discharge problems that arise during heavy rain episodes.
The tender has a budget of €238,715.03, with an execution timeline of eight weeks for the removal of the existing collector, which consists of a DN300 asbestos cement pipe. This will be replaced with a DN400 SN8 PVC-U pipe, offering greater capacity and improved discharge conditions, as the City Council detailed this Wednesday.
Service Continuity Measures
To ensure service continuity during the execution of the works, the council explains that temporary pumping systems will be installed and alternative conduits will be established.
Inmaculada Medina, the councillor for Water, has stated that the current conduit has limitations in hydraulic capacity and lacks proper gradient, leading to sediment accumulation and sewage discharges. Upgrading the sanitation infrastructure will ensure more efficient service and reduce the risk of incidents during heavy rainfall.
Project Execution Details
The operations will take place in two distinct sections: an interior section running through the affected estate and an exterior section outside of it. In the initial section, which is not accessible by vehicle, work will be conducted via pedestrian access.
The intervention includes the replacement of inspection chambers, the adaptation of supports and pillars that uphold the installation in the aerial sections, and the construction of a new 14-metre perimeter wall within the estate.
The new conduit will be anchored to the supports using clamps, ensuring a uniform gradient of the layout and increasing the evacuation capacity of the system.
Health and Safety Considerations
The project also incorporates a specific asbestos removal plan for the disposal of the asbestos cement conduit and includes all necessary health and safety measures for the execution of the works.
This intervention, for which interested companies may submit their bids until 9 September via the Public Sector Procurement Platform, is part of the initiatives outlined in the Strategic Plan for the Comprehensive Water Cycle 2024-2033, which is allocated €857 million to modernise the hydraulic infrastructures of the Gran Canarian capital.
