The Project
CAISA was contracted by Rubatec and ATLL to carry out the installation of a new flow meter in the Arteria del Vallès, a DN1200 main drinking water supply pipeline, at 9 metres depth next to the Riera de Caldes.
The intervention required the removal of a 12-metre section of existing DN1200 concrete pipe and its replacement with a new steel section incorporating the DN1000 flow meter, with the necessary reducers at both ends to adapt the diameters. The complexity of the work lay in the need to execute it continuously over 24 hours, without interrupting the water supply to network subscribers at any point, which demanded extraordinary logistical planning and team coordination.
The work was carried out in a confined space under working pressure, with all the safety protocols required for an intervention of this scale on critical supply infrastructure.
Specifications
| Parameter | Value |
|---|---|
| Pipeline | Arteria del Vallès |
| Original diameter | DN1200 (concrete) |
| Section removed | 12 metres |
| Flow meter installed | DN1000 |
| Depth | 9 metres |
| Duration | 24 continuous hours |

Results
The intervention was completed within the planned 24 hours with no interruption to the supply service. The new flow meter was operational and validated upon completion of the works, enabling ATLL to have accurate flow data at this strategic point in the network.
This project exemplifies CAISA’s capability to execute technically and logistically complex works on critical infrastructure, to the most stringent safety and scheduling standards.
