HISTORIC EVOLUTION2

VINARÒS

The Valencian Community carries out duties with regard to water sanitation and treatment since the year 1986. RD 1871/85.

In 1986 only 31% of the population had waste-water treatment.

70% of the installations did not properly work.

Between the years 1986-1991, the percentage of population served reached 66%.

Despite the efforts, there was a great structural deficit.

The Valencian Community carries out duties with regard to water sanition and treatment since the year 1986.

RD 1871/85.

The infrastructures executed did not offer any security regarding their suitable maintenance.

To solve this needs the Cortes Valencianas approved the Law 2/1992.

Established by the Law 2/1992. It works as a tax.

It guarantees the economical resources to finance the maintenance and operational costs of the EDAR (Sewage Treatment Plants).

It charges the production of sewage, by means of the consumption.

5 CONSTRUCTION OF THE INSTALLATIONS

I MASTER SANITATION PLAN

- It was executed during the years 1993-2000.

- It represented the construction or redesigning of the 300 WWTP in towns with more than 500 inhab.

- The investment was 533 M€, (338 M€ by the Generalitat).

II MASTER SANITATION PLAN (D197/2003)

Mainly justified by two needs :- To adjust the water treatment to the

new legal regulations.- To adapt the capacity of treatment to

the current and future demands.

The time horizon is 2001-2008.

Expected investment of 1.054 M€. Covered population 99,98%.

7 REUSE OF TREATED WATER

- In the II Master Sanitation Plan, the reuse of water represents 18,2% of the investment.

- Aspects having an influence on the reuse of treated water:

1. Availability of resources.2. Degree of quality.3. Distance to the point of exploitation.

7 REUSE OF TREATED WATER

184 hm³/a directly reused (36%).

The reuse of treated water in the Valencian Community is one of the most important in Spain.

225 hm³/a reused altogether (44%).

At the end of 2010, we would be able to reuse 350 hm³/a (68%).
