The town of Sant Jaume d'Enveja, in the province of Tarragona, does not currently have a system of for waste water treatment, carrying out the discharge of waste water directly to the River Ebro. Waste water discharges are characterised by being greatly diluted in the summer months by mixing the sewage with the surplus irrigation from rice fields, while in the winter months such dilution does not occur. The action involves the construction of a new waste water treatment plant which can handle an average flow of 2,426 m3/day and construction of auxiliary pipelines.

The town Ulldemolins, in the province of Tarragona, does not have any waste water treatment system, currently discharging them through two points to the river Montsant and a third point in the Olla canyon. The action involves the construction of a waste water treatment plant capable of treating current discharges current and those planned in the future.

STATE OF THE ACTION:
Works completed.

The town of Horta de Sant Joan, in the province of Tarragona, does not have waste water treatment system, since the waste water treatment plant is out of service, causing dumping of untreated discharges into ravines of Vilans and Les Vinyasses, tributaries of the river Algars. The action involves the construction of a new waste water treatment plant capable of treating an average flow of 756 m3/day of waste water and construction of collectors required to address dumping in the ravines indicated above.

STATE OF THE ACTION:
Works completed.

In some sections of the lower area of the Ebro, lack of investment and facilities have made the river more of a problem than an asset for the conservation of a heritage that generates wealth and identity. The purpose of this action is the construction and equipping of four visitor centres in the towns of Xerta, Aldover, Mora d'Ebre and Tivenys. The new interpretation centres will disseminate to the public information related to fluvial dynamics, galachos, islands, meanders and river beaches that exist in the lower Ebro

In the lower section of the river Ebro, from Flix to the mouth, there is only one obstacle that causes a breakage of river continuity: the Xerta weir. Currently there is a fish ladder in the weir, that is of a successive pond typology, located about 80 m from the right bank, which is not considered suitable for the passage of river wildlife due to its geometric characteristics and typology. This project involves the construction of a new fish ladder that allows the presence, in the delta area, of ​​wildlife species that currently have a minority representation.

Formerly, in the final section of the floodplain of the river Ebro, there were many points for the discharge of karstic aquifers from the surrounding mountains. Today most have disappeared. The only two remnants of this ecosystem that pose a unique haven of biodiversity are the Marjal of Campredó on the left bank of the Ebro and the Carrova ullals on the right bank, which have a notable state of degradation.

Human activity has modified part of the river Ebro by invading it with crops that have reduced the native vegetation of the area. Moreover, all kinds of rubbish and debris have been tipped onto the riverbanks, which contributed to finding vertical banks caused by erosion processes, which generate various areas with a mismatch of trees, and areas where the cane falls towards the river .

At present the banks of the Ebro are heavily modified by human activity, as they have been invaded by crops whose implementation has changed the topography of the banks and floodplain. Furthermore, dumping of all kinds of rubbish and debris on the banks of river, contribute to generate vertical banks cause by erosion processes. The action is to develop and restore a riverside ecosystem, which has a certain degree of naturalness and where ecological processes of this environment can be restarted, in a strip of sufficient length.
