    Pemba Island, part of the Zanzibar Islands, is a remarkable place. The traditional economy of rich fishing grounds and growing cloves has recently been boosted through the rapid rise of tourism. All these activities depend on the island’s value as an environment of exceptional beauty and purity – but more visitors mean more sewage and a corresponding growth in environmental risk.

    Until recently, raw sewage was being discharged straight into the sea. This was in part due to lack of environmental awareness and in part due to the lack of money needed to remedy the situation.  

    Not only was this disastrous for the sensitive marine environment. It was also a serious risk to public health, particularly during the regular rainy season, when flooding is the norm in low-lying island areas.

    ECVM (the European Council for Vinyl Manufacturers), in partnership with Dutch NGO Agua4All, donated both the PVC pipes and the necessary technical expertise required to build a new waste water system on Pemba.
    Wavin products have been an enormous advance on traditional civil engineering materials. Since the programme went live in 2009, we have not experienced a single problem in the operation of the sewerage system.

    The project uses international aid and enables local communities to help themselves - improving quality-of-life for local residents; minimizing environmental impact; and boosting the local economy.

    Wavin provided over 590 Tegra inspection chambers and all the plastic pipe and fitting needed to complete this extensive 12.1 kilometre infrastructure project.

    Our solutions

    Wavin Drinking Water Solutions

    Drinking water

    Delivering clean water efficiently and safely has become a world-wide problem. Water is lost due to leakages and ageing networks. We need to improve the distribution of clean drinking water from source to tap. We will work towards these goals by raising the quality and performance of high-pressure water distribution networks, improving safety levels of indoor drinking water supply, and building towards a new (smarter) ways of managing drinking water.
    Wavin solutions for heating and cooling

    Heating & Cooling

    People require increased comfort and well-being in the places they live and work. We need to design, build and use comfortable living environments in the most efficient and sustainable way. With the Wavin Indoor Climate solutions we aim to make a positive contribution in many different ways. We contribute to lowering energy usage when heating or cooling our homes, offices, hospitals, and more. Clean and fresh air has so many health and wellbeing benefits.
    Wavin Solutions for Rainwater

    Rainwater

    Climate change with massive rainfall, extreme heats and droughts put pressure on cities. Growing populations increasingly ask for greener living space. We need to (re)act to climate change and build livable and loveable cities. We will work towards these goals by creating integrated rainwater management solutions, countering the risk of flooded streets, avoid urban heat stress, and support greenification of cities. Our Wavin solutions already contribute.
    Wavin Sewer Solutions

    Sewer

    Millions of people have no or limited access to sanitation facilities. Simultaneously, ageing and poorly designed sewer systems contaminate groundwater resources. We need to future-proof wastewater transport and make sanitation accessible for everyone. We will work towards these goals by building sewer systems with modern technology, preventing leakages, corrosion and clogging of sewer systems, and boosting renewal of sewer infrastructure.

    Wavin Waste Water Solutions

    Waste Water

    We need to future-proof wastewater transport and make sanitation accessible for everyone. Although drainage pipes may sound like a simple form of construction, there are many considerations behind a good and solid drainage system in buildings. We offer a range of market-leading and BIM-supported waste-water solutions incl. low-noise. With our wealth of knowledge and expertise, we can help you to create the optimal solution for your next project.
