Construction of a non-drinking water network in viladecans

From EPSA - European Public Sector Award

[edit]

Viladecans is a city located on the Mediterranean coastline, some 12 km. south of Barcelona. It covers an extension of approximately 21 km2 and has a population of 64,681 inhabitants (2010). Since 2001 the green areas have increased by 40% now covering 84.72 ha.

Viladecans Council has embedded itself in sustainable development, by preserving natural resources and contributing to the eradication of overexploitation of natural resources. This means the necessity of optimising water management and improving efficiency in the use of water. In 1996, the City Council prioritised water saving and water reusing in Agenda 21. The Reused Water Net Project was presented to the Cohesion Fund in May 2003, and was approved by the European Commission in October 2003. The project aims to use 500m³/day of the effluent coming from the waste water plant Gavà-Viladecans, and complement that with non-drinking water from aquifers. This part of the effluent will be treated for non-drinking purposes and will be connected to the reused water net. At the moment, this net is connected to the aquifer at the end of the waste water plant enlargement building.

This project, proposing the use of new local water resources in Viladecans, implies using regenerated water and well water for irrigating the Viladecans green areas and cleaning its street, is an innovative project as it proposes the use of such resources to irrigate all the green areas covering a surface of 31.2 ha. It is, in fact, a proposal to implement different water resource supply networks in order to meet the different purposes the water is currently used for in Viladecans.

This project to reuse part of the waste water treated at the Gavà – Viladecans purification plant, implies a decrease of the water the plant currently sends to the sea. The project allows to reuse 180,000 m3 per year, meaning that 4.8% of the total flow treated by the plant would not be dumped into the environment. On the other hand, the use of this treated water and the water extracted from the wells to irrigate the green areas and clean the streets of Viladecans, also involves a saving of drinking-water resources quantified at 268,000 m3 per year; 7% of the current consumption (180,000 m3 of regenerated water and 88,000 m3 of phreactic water).
