Why should you work with us?
Water has become critically important not only for future generations but also for ourselves. With regulations implemented by the Ministry of Environment, Urbanization and Climate Change, rainwater harvesting and greywater systems will be mandatory in large-scale private and public buildings starting January 1, 2026.
All products we distribute are food-safe, quick to install, require minimal maintenance, are easy to transport, have high load-bearing capacity, do not cause land loss, and fall under the category of green technologies recommended by the EBRD for their environmentally friendly nature. They are also suitable for green certification and funding applications for buildings.

Frequently Asked Questions
What is rainwater harvesting?
Rainwater harvesting is the process of collecting rainwater from roofs or open areas, filtering it, storing it, and reusing it as needed. This method saves water and is an important step towards sustainable living.
What is the purpose of rainwater harvesting systems?
- To control the risk of floods.
- To support groundwater resources.
- To alleviate the burden on city infrastructure.
- To create a water reserve that can be used during drought periods.
Therefore, rainwater harvesting is a sustainable water management solution that should be implemented not only in new residential areas but also in existing urban fabrics using a "sponge city" approach.
How can rainwater harvesting be done?
The problem isn't the decrease in rainfall, but
Where can collected rainwater be used?
Toplanan yağmur suyu, basit bir ön filtrasyon sonrası bahçe ve peyzaj sulama, rezervuar besleme, temizlik ve endüstriyel kullanım gibi birçok alanda değerlendirilebilir. Sadece rezervuarlarda kullanılması bile bina ölçeğinde yaklaşık %35 su tasarrufu sağlayabilir. Ancak içme suyu olarak kullanımı için ek arıtma sistemleri gereklidir.
What are the key differences between traditional and modern transactions?
Traditional methods (open channels, ponds, concrete or plastic tanks) expose the water to pollutants and sunlight, leading to bacterial and algae growth and evaporation losses of up to 40%. Additionally, concrete and plastic tanks have disadvantages such as high installation costs, cracking, maintenance needs, and a limited lifespan.
Modern rainwater harvesting systems protect water quality by storing water underground in a closed and protected manner, allow for the use of the above-ground area thanks to their modular structures with high carrying capacity, and offer a more economical and sustainable infrastructure solution with their quick installation.
Rainwater harvesting or seawater desalination?
Water scarcity is seen as one of the biggest problems of the future. These two methods are not actually competing solutions, but rather complementary ones. Rainwater harvesting creates a low-cost and sustainable local resource, while seawater desalination is a method with ecological impacts due to high energy consumption and the resulting saline wastewater. Therefore, the most appropriate approach is to first capture and utilize rainwater in cities, and then use desalination technologies for the remaining needs.
What makes Hydrain different?
At Hydrain, our goal is to ensure users have a seamless experience in the long term and that water is used in the most efficient way. With our team of architects and engineers, we develop scalable and holistic water management solutions for every project, from individual users to large corporations.
We are also the Turkish distributor for globally renowned brands in water management, such as Atlantis Corp. (Australia), Wisy AG (Germany), and Farmland Rainwater Harvesting Systems (India). We choose these brands because they offer reliable, long-lasting, and sustainable solutions.
How do filtration systems work, and what should be considered?
Filters separate pollutants such as leaves, dust, and sand from rainwater, transferring clean water to the reservoir and maintaining water quality. Wisy filters are self-cleaning systems that operate with 95% efficiency. Filter selection should be based on the roof's rainwater collection area, not the pipe diameter.
What should a rainwater storage tank be like?
Rainwater storage tanks should ensure that water is stored underground in a closed system after pre-filtration. The tank materials must be food-grade certified, protect the water from sunlight, contamination, and evaporation, and be seismically safe. Furthermore, they should have a load-bearing capacity of 40–150 tons per m², allow for the use of the upper area without causing land loss, and have a flexible design that can adapt to different project geometries.
How does the installation process proceed?
For residential projects, it might take a few days, but for larger projects, it could take longer. Our difference is that our team of architects and engineers follows the project from start to finish and offers the most suitable solution.
Do your systems require maintenance?
Yes, but to a minimum extent. Aside from cleaning the filters and checking the tanks, there isn't a major burden. What's important for us is that users can easily operate a sustainable system.
How do these systems contribute to the environment?
- It reduces tap water consumption.
- It helps to conserve water resources.
- It saves energy.
- It contributes to sustainable urbanization.
Do you have customized solutions for individuals and organizations?
Yes, we do. Our approach is to treat every project as unique. Whether it's an individual user or a large corporation, our team of architects and engineers develops scalable solutions tailored to their needs.
How is pricing determined?
For us, pricing is not just about cost; it also encompasses long-term benefits. After initial research and needs analysis, we present the most suitable solution and offer. Our goal is to make sustainability accessible to everyone.
