Introduction

Àngel Simon Chairman of the Board of Directors of Aigües de Barcelona

Three out of every ten people do not have access to drinking wa- ter, while six out of every ten people do not have access to safe sani- tation. In other words, two-thirds of the global population do not have access to a system that can provide safe water. In light of the fact that we are managing a vital resource, and that access to water is a ba- sic right, we have decided to tackle the key challenges facing society by incorporating the United Nations’ Sustainable Development Goals (SDG) into our everyday working practices, in order to work towards a fairer, more equitable and more sustainable society. In this respect, since 2012 we have promoted the Solidarity Fund to help struggling families, and we have signed agreements with 22 municipalities in the metropolitan area in order to ensure a supply of water for those who cannot afford it. Moreover, in 2018 we cancelled the debts accumulated by families in vulnerable situations. The Social Tariff for pensioners and the unemployed, billing in installments and flexible payments are just some of the other mechanisms that help us ensure universal access to water. To date, 39,000 families have bene- fitted from these initiatives. In the fight against climate change, and in accordance with the SDG, we have worked hard to transform our plants into “eco-factories”, or generators of resources, in order to reduce the generation of waste and shrink our carbon footprint. We have also updated our facilities to enable the use of reclaimed water and have launched a number of awareness-raising campaigns. These measures have enabled us to advance our sustainable development strategy and our commitment to the circular economy, in line with the goals set by the United Nations.

Ignacio Escudero Director of Aigües de Barcelona

Aigües de Barcelona’s 150-plus years of history are testament to our work as managers of the complete water cycle within the metropolitan area. It is complex work, carried out by a talented team of professionals who strive tomaintain our excellent levels of service, 24 hours per day, 365 days per year. Our push for continuous improvement hasmade us an inter- national benchmark, as demonstrated by the record number of technical visits to our facilities this year (7,830 people from 25 different countries). We are aware of the need to share our expertise and build new re- lationships, which is why we promote projects to raise awareness, en- courage innovation and collaborate with public administrations to pro- mote sustainable development and the circular economy. For young people, we also promote technology-oriented careers and encourage an interest in science by offering internships and taking part in exhibi- tions and other activities. We continue to adopt the latest technologies and control systems with the help of our technology centre (Cetaqua) and our laboratory, both of which have become international benchmarks and centres of excellence. We work alongside universities and R&D centres, and this year we celebrated the 30th anniversary of our agreement with the University of Barcelona. One of our most ambitious projects for 2018 was the 60k Plan to improve hydraulic efficiency by an amount equiva- lent to the consumption of a city with 60,000 inhabitants. With regard to management, we are committed to providing ob- jective and responsible information on our daily activities via the Open Portal: a platform for transparency that facilitates communication be- tween Aigües de Barcelona and citizens. We also guarantee real and effective equality of opportunity for men and women via our Corporate Plan and Equality Plan, and work with organizations to promote the in- tegration of vulnerable social groups. These measures drive us forward and enable us to achieve excellence as a sustainable company. As service providers, our primary aim is to guarantee the quality and continuity of the supply of drinking water to citizens, without de- stroying our resources (and, even more importantly, those of others). We are also responsible for the treatment of waste-water. This has en- abled us to make progress in completing the water cycle, following the example set spontaneously by nature. Likewise, we are keen to make progress in completing the cycle of resources that are found in waste-water. For this reason, we are working towards transforming our waste-water treatment plants, which currently house sludge and pu- rified water, into “eco-factories” that produce reclaimed water, recover valuable elements (such as phosphorus) and generate biogas. In turn, this will enable us to make progress with regard to the circular econo- my, without which sustainability is impossible. Citizens, along with all of the economic and social actors, both public and private, must join forces in order to build a sustainable sys- tem. Aigües de Barcelona has been working towards this goal for a while now. We are committed to it, and we invite everyone to share in this commitment. Sustainability is at the heart of the corporate culture of Aigües de Barcelona, as demonstrated by the results detailed in this report. It is for this reason that we have collated and shared these results, in the interests of collective responsibility.

COMMITTED TO SUSTAINABLE DEVELOPMENT We are committed to making progress towards sustainable development through our activities and by acting in accordance with the United Nations Sustainable Development Goals. We strive to maximize our positive impacts and reduce our footprint.

Our society, and the world as a whole, is experiencing a historic period of uncertainty, characterized by major environmental challenges that are putting the sustainability of the anthroposphere at risk and a global economic panorama that is marked by the recent financial cri- sis. Such circumstances demand an enormous commitment from Aigües de Barcelona as an organi- zation. It is a commitment that we must learn to bear and to internalize. The concentration of the popu- lation in large urban areas, the im-

pact of tourism and the needs of the agricultural industry in a region with scarce water resources are factors that oblige us to optimize the use of our water. In the future we will face more and longer periods of drought, which will present not only difficul- ties, but also a challenge for the supply of water to Barcelona and the metropolitan area. We need to ensure that water resources are col- lected and used properly. Consequently, Aigües de Bar- celona is committed to reclamation and recycling (i.e. full completion of

the water cycle) as the best way of guaranteeing the supply of drink- ing water. We have the necessary technology. However, the effort and commitment required to ensure sound water management can only be achieved with the help of an informed and aware citizenry. Achieving sustainable develop- ment is a challenge we must all face together.

The actions of today’s society have an enormous impact on sustainability. Aigües de Barcelona is facing the challenges of the future by committing to reclamation and recycling as a means of guaranteeing the supply of drinking water.

WATER Aigües de Barcelona is committed to seeking out new sources for water collection and raising awareness among consumers of the need for responsible consumption. We know that water is a scarce resource, which is why we strive to create an efficient network and reduce the volume of leaks. We both champion and guarantee the high quality of our water, while remaining committed to protecting water reserves and making progress in the comprehensive management of water resources. We are wholeheartedly committed to excellence in management: because access to clean, safe water is a right, resources must be consumed responsibly, and ensuring that the natural environment remains unpolluted is a top priority.

Controlling the quantity and quality of water is a key part of re- source management. Aigües de Barcelona supplies nearly 3 million

people with water that originates from several different sources: surface water, groundwater, and desalinated water. The scarcity of

water resources presents a chal- lenge that requires the adoption of new methods of treating and recy- cling water.

We ensure sustainable water management

Aigües de Barcelona is com- mitted to recycling water as a key strategy for guaranteeing the fu- ture supply of water for the Barce- lona metropolitan area. We invest in projects that make it possible to re- spond to periods of irregular rainfall and find solutions for limited water resources in internal reserves. 2018 saw the supply of 2.8 hm 3 of reclaimed water for agricultur- al irrigation, cleaning of parks and gardens, and environmental uses. We intend to increase this amount year-on-year.

Reclaimed water to return to the River Llobregat

Our water recycling project at the Baix Llo- bregat treatment plant is designed to return wa- ter to the river. Usually, the water from the plant is discharged safely and responsibly into the sea, after it has undergone the necessary treatment. The project incorporates a waste-water reclama- tion facility and 15 km of pipes, and after under- going special filtration and disinfection processes the water is suitable for discharging into the River Llobregat, as it is of excellent quality and can be integrated back into the water cycle. The cost of recycling this water is 14 euro cents per 1,000 litres: three times lower than the cost of desalination.

They also provide assistance in operations or situations that may affect water quality (e.g. disinfection after a pipe has been put into operation, dealing with pos- sible intrusions, etc.). As such, they are essential to safeguarding the system and guaranteeing the complete safety of the water supplied by Aigües de Barcelona.

We make the network more efficient

The improvements to the net- work’s hydraulic efficiency are the result of a specific annual pro- gramme comprising several dif- ferent areas of focus, such as the preventive diagnosis of leaks via information provided by the com- partmentalization process, and the use of models in prioritizing net- work upgrade activities and mea- suring consumption. The network’s hydraulic ef- ficiency rating for 2018 was 85%, which translates to a “highly satis- factory” rating for the water supply operation, especially if we take into account the network’s pressure levels, which enable us to guar- antee a direct supply of water to buildings up to eight storeys tall.

If the network’s efficiency level is 85.04%, where does the rest of the water go?

5.93% Actual losses caused by break- downs and small imperfections that can only be detected by inspecting the network.

Precisely monitoring the flow rate, supervising the network and inspecting meters can all help to reduce losses.

0.09% Consumption derived from net- work operations, such as cleaning and disinfecting pipes and tanks.

8.84% Apparent losses through meter in- accuracies and fraudulent or illegal consumption.

We have reached our goal of achieving a network efficiency rating of 85.04%, which is 10 points higher than the average for water companies in Spain (according to the Spanish National Statistics Institute).

60k: a new project is born

The culmination of the 85 Plan came in 2017, when our perfor- mance exceeded the target of 85%. This also signified the com- mencement of a new challenge: the 60k Plan. Under this new plan, for which the target year is 2020, Aigües de Barcelona is commit- ted to reducing unregistered consumption by an amount equiva- lent to the annual consumption of a town of 60,000 inhabitants.

With preventive maintenance and periodic checks, our efficiency levels can approach 100%.» Àngel Cuenca, operations

Remote meter reading: a useful and flexible service for customers

Technological innovation en- ables us to manage water re- sources more efficiently and offer a more reliable and comprehensive service. In this regard, the remote reading system gives meters the capacity to emit a signal, so that consumption can be checked per day and per hour, at any time and from any location. Alerts for excess consumption and leaks provide customers with useful and important information, allowing them to find timely solutions to problems that might otherwise result in unexpectedly high water bills.

CITY Aigües de Barcelona is committed to taking action aimed at improving the biodiversity of our surroundings and increasing the use of green energy. We are working hard to reduce CO 2 emissions and mitigate the effects of climate change. We are also committed to the principles of the circular economy and have integrated them into our management activities (e.g. with the introduction of eco-factories). Additionally, we promote a network-based approach to our activities and play an active role in the development of the local community. We believe that halting the loss of biodiversity is an obligation, and using clean, sustainable energy is vital in order to make cities more resilient. There is a pressing need to fight against climate change and its impacts and to help reduce waste. And if we are to make sustainable development a reality, we need to forge alliances at the local and international level.

One of the challenges of the 21st century is the fight against climate change, which requires a reduction in the emission of green- house gases, the promotion of re- newable energies and an increase in energy efficiency. Natural disasters and chang- ing weather patterns, resulting in

more severe periods of drought, make water management even more precarious. In turn, this ne- cessitates measures designed to improve and adapt. At the same time, the quality of the river water is falling due to human activity, while the amount available is also shrinking (by

around 60% over the last 50 years). For these reasons, we are striving to protect biodiversity, become energy efficient and self-sustain- able, generate less waste, and promote recycling and reintroduc- tion into the water cycle through projects that help develop the cir- cular economy.

We help fight climate change

Since 2015 we have reduced our carbon footprint by 34.83%, significantly exceeding the target reduction of 10% set in the Aigües 2020 strategic plan.

Climate change is one of the great challenges facing today’s society. It is a global challenge that af- fects both quality of life and availability of resources. The fight against climate change must allow for the supply of high-quality water, while ensuring that cit- ies are healthy and sustainable places to live. By calculating our carbon footprint, we can im- prove our processes and reduce the emission of greenhouse gases.

Aigües de Barcelona’s carbon footprint

What is a carbon footprint? It is a measurement of the amount of greenhouse gases (GHG) emitted in relation to a product or activity. GHG emissions are divided into three categories:

Category 1 · 30% Direct emissions from our own sources or sources we control

Category 2 · 0% Indirect emissions produced during the generation of the elec- tricity we purchase

Category 3 · 70% Other indirect emissions: activ- ities related to the company’s objectives and for which we have reliable data

Corporate travel

Emissions produced through the operation of WWTPs

Transportation of materials, reagents and waste

Fluorinated gases

Electricity consumed by the network

Consumption of reagents

Burning of fuel

Company vehicles

Final disposal of waste

Emissions from plant effluent

48

Our own tool

We have been calculating our carbon footprint since 2011. Our cal- culations are made in accordance with the guide produced by the Climate Change Office for Catalo- nia (CCOC) and using our own tool, Carboweb, which incorporates a specific methodology for the com- plete water cycle developed by the Cetaqua water technology centre. Minimizing our environmental impact, embracing clean energy and promoting the circular economy are at the heart of Aigües de Barce- lona’s strategy. Consequently, we have implemented a range of mea- sures to reduce the carbon footprint generated by our daily activities.

“Carbon footprint” is a term we hear frequently, but we know little about what it means and how to reduce it. More needs to be done to reduce emissions and publicize the achievement of targets. » Maria Josep Batalla

Initiatives to reduce GHG emissions

›› Sustainable mobility: • Fleet of 120 fully electric vehicles .

• Road Mobility Plan and Corporate Travel Plan for the headquarters of Aigües de Barcelona (Collblanc centre). • Working from home, which helps reduce emissions and improves work-life balance. ›› Buying emissions-free energy: Almost 100% of the ener- gy purchased as part of the water cycle is from guaranteed renewable sources. ›› Installation of solar panels and pergolas to generate solar energy.

The circular economy: our strategy

Consumption of energy from renewable sources

By generating our own energy from sources other than fossil fuels, we are able to reduce our carbon foot- print and give a new lease of life to the large volume of waste we generate.

We generate biogas from treatment sludge and are committed to using alternative sources that reduce methane emissions.

174,144 kWh of electrical energy from the solar park 18,667,976 kWh of electrical energy produced through cogeneration using biogas

Zero waste objective

We prioritize the optimization of the resourc- es that are necessary for our activities and reuse waste materials that can be converted into a re- source. In turn, this reinforces our circular econo- my-based strategy. In 2018 we reused 89% of the waste generated by our WWTPs and 71% of the waste generated by our DWTPs.

Almost 10% of the energy we consume is renewable energy generated at our own facilities.
