Portugal is currently navigating a critical transition in its water management strategy. As climate change intensifies, the contrast between the rainy northern regions like Porto and the arid southern plains of the Alentejo has forced the nation to prioritize advanced Water Storage and Drainage Systems. The Portuguese industrial sector is increasingly adopting "Sponge City" concepts to mitigate urban flooding, particularly in historic districts where traditional sewage systems are being upgraded with modern geosynthetic materials.
As a leading partner for Portuguese engineering firms, we provide the technical backbone for large-scale infrastructure. Whether it is supporting the expansion of the Alqueva Dam irrigation network or securing the structural integrity of new logistics hubs in Setúbal, our geomembranes and drainage solutions are designed to withstand the unique Mediterranean-Atlantic climatic stressors.
Our products meet stringent EU standards and Portuguese APA (Agência Portuguesa do Ambiente) environmental guidelines.
Specialized water accumulation plates designed for the vineyard regions of the Douro Valley to optimize water retention.
Precision manufacturing using AI monitoring to ensure zero-defect geomembrane production for hazardous waste containment.
Lisbon and Cascais are pioneering siphonic drainage systems to manage flash floods, reducing the burden on municipal pipes by up to 40%.
Alentejo's intensive olive and almond groves are utilizing flexible permeable pipes to recycle sub-surface water, promoting sustainable irrigation.
Modernization of Portuguese "Aterros Sanitários" requires high-density HDPE liners to prevent leachate from contaminating groundwater.
From the rugged coastlines of the Azores to the industrial zones of Aveiro, our water management solutions are everywhere. In coastal civil engineering, the high salt-mist environment requires corrosion-resistant geosynthetics. Our LDPE/EVA Geomembranes provide the necessary flexibility for terrain that suffers from seismic activity, a known factor in the Lisbon metropolitan area.
Furthermore, the Portuguese government’s commitment to the PENSAARP 2030 (Strategic Plan for Water Supply and Wastewater Management) has accelerated the demand for high-performance drainage nets and geogrids in road construction, ensuring that the A1 and A2 motorways remain safe and dry during the Atlantic storm seasons.
The company specializes in the production of smooth geomembrane, rough geomembrane, double color geomembrane, geotextiles (polyester short fiber non-woven fabric, polyester long fiber non-woven fabric, polypropylene short fiber non-woven fabric, hot-rolled non-woven fabric), drainage board, drainage net, geogrid, geocell, flexible permeable pipe, plastic blind drain and other environmentally friendly geosynthetic materials. Relying on a long-term and stable raw material supply system and strict product formulas, we can customize various material products such as HDPE, LDPE, EVA, and ECB according to customer needs.
Our company's products have a wide range of applications, featuring anti-aging, long service life, environmental friendliness and non-toxicity. It is mainly applied to environmental protection landfill sites, artificial lakes, chemical plant slag yards, tailings DAMS, highways, railways, water conservancy, power, soil and water conservation, environmental greening, various breeding farms, canals and reservoirs and other infrastructure facilities in the Portuguese market.
Certifications & Excellence: The company has passed the ISO9001, ISO14001 and OHSAS18001 certifications, and has professional technical personnel and advanced equipment and instruments. There are currently over 60 employees, including 3 chief chemical process engineers, 5 mechanical engineers and 9 professional equipment operation engineers.
Technical Strength: The above-mentioned professionals have many years of practical working experience. The strong technical strength ensures the stability and forward-looking nature of the products. The company has always kept an eye on the world's advanced level, maintaining leading geosynthetic material production lines and testing equipment.

Send Inquiry NowThe Water Storage and Drainage System market in Portugal is undergoing a paradigm shift. Historically, water management focused on centralized reservoirs. However, modern engineering in cities like Lisbon, Porto, and Braga is now focusing on Distributed Infrastructure. This shift is driven by the European Green Deal and the Portuguese government's "National Roadmap for Adaptation 2021-2050".
In regions like Sines and Palmela, new industrial parks are being built with "Zero Discharge" goals. This requires advanced HDPE Geomembranes for industrial wastewater containment and Siphonic Drainage Systems to manage the vast roof areas of logistics centers. Our geomembranes act as an impermeable barrier, protecting the soil from chemical seepage—a critical requirement for the automotive and pharmaceutical industries prevalent in Portugal.
Agriculture accounts for approximately 75% of water consumption in Portugal. The Alqueva Irrigation Project, one of the largest in Europe, utilizes thousands of kilometers of canals. To prevent water loss through evaporation and seepage, our LLDPE earthwork films and flexible permeable pipes are essential. By implementing sub-surface drainage, Portuguese farmers can reduce water wastage by 30%, a vital saving in a region prone to severe droughts.
Portugal’s 1,793 km coastline is vulnerable to rising sea levels. Hydraulic engineering projects in Aveiro and the Algarve utilize Needled Filament Geotextiles for soil stabilization and filtration. These materials prevent the fine sand from washing away while allowing water to pass through, maintaining the structural integrity of sea walls and coastal promenades.
Old cities like Évora and Coimbra face challenges with heritage preservation and modern drainage. Our Water Accumulation and Drainage Plates (Concave/Convex cells) allow for the creation of "Green Roofs" and "Permeable Pavements" that respect the aesthetic of the city while providing 21st-century flood protection. These systems store excess rainwater and release it slowly into the municipal system, preventing the catastrophic "flash floods" that have historically affected Lisbon's Baixa district.
As a forward-thinking manufacturer, we integrate AI-based quality control in our production lines. Every square meter of geomembrane is scanned for thickness consistency and micro-perfections. For our Portuguese clients, this means a product that doesn't just meet the ISO standards but exceeds them, providing a service life that often spans decades, even in the harsh UV environment of Southern Europe.
The Water Storage and Drainage System industry in Portugal is no longer just about pipes and pits. It is about Environmental Resilience. By choosing Taian Changhong Engineering Materials Co., Ltd., Portuguese companies are choosing a partner dedicated to the future of the nation’s infrastructure. From the Douro to the Guadiana, our materials are the silent guardians of Portugal's water future.
