2016 Guided tours of water infrastructures

During the three days of Iwater, all registered delegates at the show will be entitled to join tours of some of the key water management facilities in the city ofBarcelona and its metropolitan area, some of which are also international benchmarks.

Places are limited and Two groups (in Spanish and English) will be organised for each tour and the meeting and pick-up point will be the Gran Vía venue.

EDAR and ERA in El Prat de Llobregat + recharging water tables by injecting recycled water

visits Edar

A visit to the wastewater treatment plant (EDAR) in Prat de Llobregat which includes a water regeneration station (ERA) with a tertiary treatment facility and ultrafiltration and osmosis systems which allow the water table to be recharged by injecting regenerated water.

This visit makes a tour of the water treatment plant in Prat de Llobregat, which is one of the biggest and most modern wastewater treatment plants in Europe. It can handle 420 million litres per day, which equates to the water used by two million inhabitants and their associated economic activities (equivalent habitats). The plant also has one of the world's largest water regeneration stations: the regenerated water from this plant increases the hydric resources of the region by 40 million litres of water per year.

Among the various uses to which this regenerated water is put is recharging aquifers by injecting the water into a series of wells running parallel to the coast, very close to this area. The objective is to create a hydraulic barrier to prevent the intrusion of seawater.

Duration: 1 hour of total travel + 2 hours visiting the facilities.

Water Cycle Control Centre + control systems of the AntiDSU sewage system (rainwater retention tank in the Joan Miró Park)

Water Cycle Control Centre

This visit takes in two locations; firstly the Control Centre of the municipal company Barcelona Cicle del Agua, SA (BCASA), and secondly the rainwater retention tank in the Joan Miró park in Barcelona.

The guided tour starts at the Water Cycle Control Centre in the BCASA building, the municipal company in charge of the integral water cycle in the city of Barcelona, whose goals are to promote policies to improve urban drainage, the management of water sources and the integrated management of the coastal zone; promote the use of alternative hydric resources, and oversee the rational consumption of water. The visit will focus on the management of alternative hydric resource, geographical information systems, the integrated management of the coastal zone and the real-time management of Barcelona's sewage system.

This overview of the sewage system's management will be rounded off by the second part of the tour, which moves to the Rainwater Retention Tank in the Joan Miró Park. We will be able to enter the tank to get a first-hand insight into these installations, which were created to minimise flooding at key points in the city and protect the receptor medium, facilitating the treatment and purification of rainwater and thus benefiting the beaches through the optimum management of the network as a whole.

Duration: 1 hour of total travel + 2 hours in total touring the two facilities.

The Desalination Plant (ITAM) in the Llobregat Basin

ITAM

A visit to the desalination plant for the Llobregat Basin (Prat de Llobregat) to learn about the seawater processing system in this facility, which provides 60 Hm3 per year for the water network in the metropolitan area of Barcelona and its outskirts.

This visit will take a tour of the desalination plant for the Llobregat Basin, which was opened in 2009, and its process of desalination by reverse osmosis. As the source of its supply is the sea – an inexhaustible resource which is unaffected by periods of drought or a decline in water quality – this facility increases the reliability of the water supply and stabilises the quality and quantity of the water supplied. The water produced by the desalination plant is pumped to the Fontsanta tank in Sant Joan Despí by means of a 1.4 metre diameter, 12 kilometre pipeline which runs parallel to the River Llobregat for a large proportion of its route. The water is then distributed from this tank to the general mains supply.

Duration: 40 minutes total travel + 1.5 hours touring the facility.

Potable Water Treatment Plant and EDR of the River Llobregat

ETAP

A visit to the Potable Water Treatment Plant (ETAP) in the municipality of Abrera, which takes water directly from the River Llobregat. This facility also has one of the world's biggest electrodialysis reversal plants (EDR) for water treatment. The EDR eliminates a high percentage of mineral salts from the water, which is taken from the intermediate section of the River Llobregat where there is a natural potassium basin and where mining has taken place for decades (Carona, Súria, Balsareny and Sallent).

The tour aims to give an insight into the treatment process of the water taken from the River Llobregat which continues in this ETAP in Abrera, with a treatment capacity of 4 m3 per second. We will also visit the plant's EDR which uses this membrane technology to remove salts and other contaminants from the water, improving its organoleptic perception while at the same time preventing the formation of trihalomethanes in the chlorination process.

Duration: 1.5 hours of total travel + 1.5 hours touring the facility.

Visit to the Aquifer recharge Ponds at Sant Vicenç dels Horts

Visit to the Aquifer

This visit makes a tour of the aquifer recharge ponds at Sant Vicenç dels Horts to see how they work. Artificial aquifer recharging is a very widely used technique worldwide. One of the most common systems in artificial recharging is the use of infiltration ponds or basins on the surface. These are excavations made in permeable land close to the nearest source of water.

At present, the ACA has some small recharging ponds operating in Sant Vicenç dels Horts: the decanting pond has an area of 4,000 square metres and the infiltration basin is 5,600 square metres, with a recharging capacity of approximately 1.5 hm3 per year.

Aquifer recharge is a corrective measure to improve the qualitative and quantitative status of bodies of water and allows a progressive increase to the established thresholds. The recharging ponds at Sant Vicenç dels Horts are one of the measures to help improve the environment in the Vall Baixa and Baix Llobregat regions.

Duration: 1 hour of total travel + 1 hour visiting the facility.

*The visit has been cancelled due to causes beyond the organizers.
