Imma Mayol Beltran In 2010 we assisted with the commissioning of a new rainwater Chair of the Board of Directors retention tank. Following 22 months of particularly complex work on the central part of Carrer Comte d’Urgell, the retention capacity of the city’s rainwater collection tanks has been increased by 15,000 m3. This new facility, which CLABSA, which has already been brought on line, will improve drainage on the left-hand side of the city’s Eixample district and will significantly reduce the risk of flooding in the neighbourhoods of Sant Antoni and El Raval.

Through the creation of CLABSA, Clavegueram de Barcelona City Council broke away Barcelona, S.A. from the classical concept of passive management of the city’s sewer (CLABSA) is a mixed- system. This resulted in a rapid, yet economy company far reaching, transformation of the infrastructure based on accurate that was incorporated planning and efficient real-time in 1992, on the basis of management of the elements that make it up. What CLABSA has an initiative launched termed “Advanced Urban Drainage by Barcelona Management” (GADU) became a benchmark that is today recognised as City Council. The a model to be imitated, and continues Company’s main to evolve towards a more generalised business activity takes vision of sustainability. The challenge of sustainable place within the city management requires a holistic and the metropolitan approach, with a balanced blend of infrastructure and management, area of Barcelona supported by the best available and is focused on the technology in order to deal with the environmental role of urban drainage, management, design which has now become a fully and control of urban recognized reality.

drainage systems. Holistic Approach The city’s drainage network must never be considered as an isolated system, insofar as its design and subsequent performance are conditioned by both the physical environment that it has to protect and by the constantly varying patterns of precipitation, with special emphasis on those that are due to climate change. The impact on both the city and the receiving environment, along with its ecosystems, is direct and measurable. Furthermore, sanitary CLABSA 11

1.2 Development of the Barcelona sewer system

Barcelona City Council obtained Barcelona disposes of important resources for the financing detailed planning of of a number of priority actions included in this Plan from the ERDF its sewer system, forms (European Regional Development part of the Overall Sewer Fund) 2007-2013 Cohesion Funds, as well as from the Spanish State’s 2009 System Rehabilitation and 2010 Local Investment Funds. Plan, which was drawn In particular, the total for the site work up by CLABSA in 2006. projects drawn up in 2010 amounted to 18.7 million Euros, among which This Plan, which became special mention must be made of the known as PICBA’06, is Carmel-Clot Tank and the Cleaning Yard that is located above the tank in a permanent process itself. Apart from this, for reasons of of updating, in order to budgetary availability, the Rambla del Carmel Drain Project was broken down adapt it to the changing into two sections: Phase A (Avinguda dynamic of the city. de l’Estatut), which has already been laid, and Phase B (the tunnel passing beneath Rambla del Carmel) work on which will take place at a later date. This year, with co-financing provided by the Cohesion Funds, CLABSA supervised 30 different work sites at a cost of 37.1 million Euros. From among these, special mention must be made of the Urgell Tank, with a retention capacity of 15,000 m3, and the continuation of the civil engineering work on the Carmel-Clot Flood- Protection Tank, as well as the start of work on the Avinguda de l’Estatut drains, which will provide these tanks with input and outlet pipes With regard to more local, or secondary, drainage networks, in 2010 a number of studies were carried out of the Ciutat Meridiana area, complemented by the project for CLABSA 13

The City Council is fully aware of Since 2006 the the growing need to reduce the Barcelona City Council consumption of potable water and is firmly committed to reliance on km has entrusted CLABSA alternative water sources for uses of 67distribution pipelines with the maintenance other than human consumption. and operation of the In recent years, a number of systems have been created to take advantage city’s groundwater of groundwater for use in the city’s distribution network. parks and gardens, for ornamental fountains and lakes, and also to supply the hydrants for hosing down the streets. Now that the existing storage tanks systems have been extended and interconnected and new ones opened 22 with a total capacity 3 up, Barcelona can claim to have of 9.630 m access to an expanding groundwater distribution network that can be harvested for a variety of uses that are not dependent on the high quality standards required for potable water. This source currently supplies 16.6% of the total water used by the Barcelona City Council. springs This groundwater network currently 24with flow rates of 2 to 20 l/s consists of 67 kilometres of distribution pipelines and 22 storage tanks, with a total capacity of 9,630 m3. The water is supplied by 24 springs with flow rates of 2 to 10 litres per second, and in some cases is also collected from water wells, roof run-off and tunnel drainage. All such facilities are managed by CLABSA and operated via the CLABSA Control Centre. 20 Report on activities 2010

In of ducts in the sewers to line with previous years this work also carry Fibre-Optics cables, included an emergency discharge service (24 hours a day, 365 days a the management of year) and the publishing of an annual hydrological warning edition of an atlas of potentially contaminating establishments in the systems and the planning Barcelona area. As an outstanding and development of innovation in 2010, we must stress the finalisation of the work on installations for the implementing the Environmental Pneumatic Collection of Agency’s remote control drainage network water quality system, which Solid Urban Waste (RPRSU). has been operational since the end of 2010 and which is scheduled to be extended during 2011. On the other hand, 12 environmental incidents of varying kinds had to be attended to, as a result of bothersome smells, unregulated industrial dumping, either of unknown origin or as a result of accidents at industrial facilities, etc., both within the municipality of Barcelona and its Port Area, as well as in adjacent metropolitan municipalities.

R&D&I activity by SOSTAQUA Project: CLABSA, which has “Towards a Self-Sustaining Water always played a Cycle” (www.sostaqua.com). This macro-project, financed with CENIT significant role in the (Ministry of Industry, Tourism and technological progress Trade) Funds and led by the AGBAR Group, was finalised in 2010. In of the company, has it CLABSA developed a line of undergone a notable investigation for the evaluation of rainwater, in collaboration with, among increase. A number others, the University of A Coruña. of ambitious projects Work has now been completed on the campaigns for the characterisation that work began on of rainwater throughout the full five years ago were urban water cycle, along with the analysis of the possible technologies brought to completion, for the treatment required to make while a number of new this water suitable for required uses. In the end a final study of rainwater projects were also set in treatment techniques was drafted, motion that are going which included key aspects, such as the most appropriate uses for the to represent important rainwater, how a characterisation advances in terms of campaign should be focussed, how to design system for rainwater collection urban drainage in the and storage, as well as a proposal for near future. the best available technologies for the recovery of rainwater.

Rainwater Harvesting Proposal for Better DSU Medium and Long Term in Urban Environments: (Unitary Discharge System) Strategies for Flood With regard to this question, an R&I and DSS (Separating Discharge Management in Urban Alliance financing project (under the System) Technologies in and Peri-Urban Areas: title “Rainwater Harvesting”) also Rainfall Episodes: Phase 2 of this project, based on the came to an end. This project was In 2010 work went ahead on the implementation of methodologies complementary to the SOSTAQUA development of this project, with for the evaluation of risks associated project and centred on the the finalisation of phase 1, which with the flooding of urban and development of an excellent tool to analysed the available technological peri-urban areas, as well as on an assist with decision making in the improvements for the treatment of estimation of overall changes in the formulation and design of systems for the discharges of the sewer systems short, medium and long term in 3 the harvesting of rainwater in urban (DSU’s), according to legal, technical actual cases, one of which is in the environments, including aspects such as and economic criteria. This in turn Raval District of Barcelona. quality requirements, the dimensioning resulted in the development of a Finally, within the sphere of flooding of rainwater storage tanks and the tool to support the decision for the management and climate change, selection of the best treatment selection of technologies. Work also work started on two European technologies, in order to adapt this began on phase 2, complementing projects, CORFU and PREPARED, with water to the desired urban uses. the analysis of technologies on the financing from the 7th Framework basis of technical visits to actual DSU Program.

2.3 2.4 Commitment to Environmental the community action

Year after year CLABSA has given its technicians and scientists, university The dissemination support to activities programs such as representatives, public authorities and of information to the “How Barcelona Works”, an initiative public/private services companies. Of run by the City Council, and “When the 1,311 visitors, 15% were from abroad. public at large, and to it Rains in the City”, managed by the On 9th October the Urgell Retention Barcelona Contemporary Culture experts throughout Tank, with a capacity of 16,000m3, Centre (CCCB). These are educational was inaugurated, with the aim the world, with programs, designed for schoolchildren of improving the city’s drainage who want to learn about the constant regard to Barcelona’s problems. The new tank was transformation of our city, and specifically installed to avoid periodic experiences of organized at the rainwater-retention flooding in Carrer Comte d‘Urgell, tank, beneath the Joan Miró Park, managing urban Avinguda Roma, Avinguda Paral•lel during academic year 2009-2010, and the Raval, and also to minimise drainage is an area with 780 visitors. the discharge of contaminating that deserves our In 2010, CLABSA also received visits substances onto the city’s beaches constant attention. from groups of people interested during heavy rainfall. The new tank is in learning about the Barcelona located in the middle of Carrer Comte experience. These visitors came from d’Urgell, between Carrer Mallorca and a range of different backgrounds: Carrer València, in a densely populated part of the city. As a result special care had to be taken with environmental aspects to avoid, as far as possible, inconveniencing residents. Many citizens, some 450, attended the opening ceremony, expressing their interest in the operational system for this infrastructure. In 2010 one of the CLABSA projects also received the recognition of the IWA (the International Water Association) and was awarded two Project Innovation Awards, one at European level, the 2010 PIA Europe Regional Award; and the other at worldwide level, the 2010 PIA Global Award. Both of these prizes were awarded for the COWAMA Project, as the best management project, for the control and monitoring of the discharge episodes of the drainage system. CLABSA 33

In this way, at all times, Barcelona on the city and the effectiveness of City Council has access to rigorous and the corrective measures that have objective information regarding the been applied to it, both during the monitoring of environmental aspects project design phase and when it is of all of the work done in the city, in the being implemented. In this way, the widest sense. impact of the work, on the population, with regard to waste and landscaping, among other aspects, is appraised on Water Quality the basis of objective criteria and an In recent years, CLABSA’s environmental analysis is then undertaken to discover actions have been aimed at reducing to what extent the palliative measures the impact of the direct discharge proposed at the project level will of wastewater or rainwater into the minimise these aspects. receiving environment. Significant According to the policy marked advances have been made in innovative out by the Barcelona City Council, projects, as described above, and also in all of the projects drawn up by the installation of more reliable sensors CLABSA have to be accompanied by at the points of direct discharge into an environmental report. This is a the sea, with a view to obtaining better document that serves as a basis for information that has made it possible to the presentation and evaluation of the ensure that these are properly managed. 34 Report on activities 2010
