    PART 37: PUTTING SUSTAINABILITY FRONT AND CENTRE IN THE BATHROOM

    Recommended Supplier Roca discusses sustainability in order to highlight how the international hotel design industry can save water and reduce wastage… 

    Water consumption varies in hotels depending on the presence of swimming pools, saunas, laundry and catering facilities. However, water accounts for 10 per cent of utility bills in many hotels, with taps, toilets and showers comprising around 40 per cent of this total.

    Any way we can reduce water consumption is going to be good for the hotel and good for the environment.

    Bathroom manufacturing has become more sustainable in recent years and Roca has remained at the forefront of sustainable design by creating products that conserve water and protect the environment. For example, the bathroom manufacturer has reduced the capacity of its WC cisterns to optimise water consumption and developed plumbing products that shrink energy usage.

    Guests are also being far more aware of the need to reduce water and energy consumption. In-roads have already been made in this regard, with a growing number of bathrooms now having a dual-flush cistern.

    The objective is to stop unnecessary waste of water, without negatively impacting the perception of the user.

    The right choice of products plays an important part in the management of water usage. And we deliberately say ‘management’ of water usage, because, although the overall aim is to reduce water usage, each of the products still has to work effectively. The objective is to stop unnecessary waste of water, without negatively impacting the perception of the user.

    Water saving developments

    Firstly, let’s look at some products that have been designed to reduce water-usage.

    One of the latest innovations to hit the market are rimless toilets. The box rim has been eliminated, making the pan much easier to clean and eliminating areas in which bacteria can accumulate. The shape of the pan has also been redesigned, allowing us to flush very efficiently with as little as a 4/2L dual flush cistern. Considering that the average flush for new WCs is between 4L and 6L, a product like this can help to save considerable amounts of water.

    Water saving technology can also be found in many brassware solutions. For example, Cold Start technology ensures water is only heated when it is required. Traditionally, when you turn on a tap, the water will be warm. This will automatically trigger the boiler, which can be expensive and wasteful, especially in a home where multigenerational families use water at different times.

    Roca also has an exclusive piece of technology in its ECO disc cartridge, which helps to save water and energy. As the tap handle is raised, a slight resistance is reached at 50 per cent of the water flow and lifting beyond this bite point produces a full flow. The cartridge includes a temperature limiter which can be set at installation to eliminate the risk of scalding.

    Innovation and product development are making significant headway in delivering greater water savings. For instance, the ground-breaking W+W from Roca uses waste water from the basin to fill the WC cistern, thereby reducing water usage by up to 25 per cent compared to a standard 6/3 litre dual-flush WC. The W+W basin has two wastes – the basin waste and one further down the waste pipe. The user has the option of either diverting it to the mains or recycling it by storing it in the cistern ready for the next flush.

    Our Responsibility

    As well as delivering bathroom solutions that save water and reduce wastage, Roca actively works to improve sanitation and increase access to water across the world. 

    Created in 2010, the We Are Water Foundation is a Roca initiative which reinforces the brand’s historic engagement with society. On a planet with about 768 million people without access to drinking water and 2.7 billion without basic sanitation infrastructure, the Foundation aims to achieve two main objectives. First, to contribute to the spread of a new culture of water which is more caring, just and sustainable, and second, to help the world’s poorest and those with major water and sanitation problems.

    The vision of the We Are Water Foundation is to continue growing worldwide, especially in countries where the Roca Group can, through its activities, participate more intensively to identify collaboration projects and contribute to the solution for water and sanitation problems.

    Sustainable manufacturing

    Roca also knows that how its products are produced is important so has created the Eco-Roca project, which looks at the production processes at its factory, as well as the development of its products and the social activities of the company. The project has two core goals, to cut CO2 emissions and to manage waste-free industrial processes via its Zero Waste Programme.

    We have a greater understanding of the value of water and its wastage than ever before. Hoteliers and guests are mindful about the amount of water they are using and want ways to reduce it. It’s time to think seriously about water conservation.
