Project co-financed by the European Union.

Projects being carried out by the Works Department of the Planning, Infrastructures and Mobility Council.

1.1. Work on the San Isidro water treatment plant (ETAP)

Cartel ETAPThe cost of the project is 11,221,320.01 €, of which the European Union, through the Cohesion Fund, is subsidising 7,785,607 €.

This plant produces approximately 30% of the city’s drinking water and the oldest part dates from 1886, although there have been many extensions.

The project aims to solve the main problems of the San Isidro plant:

  • General obsolescence of most of the electrical and mechanical equipment, which was not efficient and frequently broke down.
  • Shortage of storage for the quantity of water treated.

ETAP 1This project is quite complex, the existing facilities are being repaired or renewed so that current and future demand can be met.

In order to deal with the problem of storage space a deposit of 50.00 m³ is being built, alongside the two existing ones.

ETAPActive carbon filters will also be installed and this will considerably improve the organoleptic properties of the water supply.

When the work is finished the plant will be completely automatic and will have a capacity for treating 155,520 m³/day in warm weather.

1.2. Extension of the Pisuerga outlet (left side).

Cartel Prolongación PisuergaThe cost of the project is 7,221,463.26 €, of which the European Union, through the Cohesion Fund, is subsidising 5,419,670 €

This project aims to solve the problem of overflowing drains in the Plaza de Poniente area, with the unusually frequent use of the existing overflow channel in the Francisco Sabadell rose garden.

VistaAnother problem is the malfunction of the main conduit of the north or Mirabel sewer, as it was observed that there are frequent overflows as soon as it rains with certain intensity in Paseo del Renacimiento and C/ Mirabel, as well as in Cardenal Torquemada and el Valle de Arán.

TuberíasThe solution to these problems is to prolong the sewer on the left side further up river, so that it intercepts with sufficient transport capacity all the main basins of the left side of the Pisuerga and empties into the Esgueva river. The lower part of the north sewer, which has insufficient capacity, will be renewed.

Extending this outlet will achieve the following:

  • Reduce the frequency and seriousness of overflow in the Poniente area, not allowing waste to flow directly into the river
  • Avoid flooding in the lower Rondilla area and in the Barrio España, by increasing the size of the sewer.
  • Make sure that the new section is leak-proof so as to avoid subsoil water infiltration and having to filter it, thus reducing costs as the section of drain to be replaced is now obsolete.
