Modern systems for water supply and drainage are complex systems that should ensure the safe management of overall water resources as the most vital component resource for life and survival of humanity, while ensuring quality and safe environment for life and daily activities. The whole sector is divided into several parts, which are due to their importance are regulated by European norms, or which are applied, or will be obligatory in most countries. Thus, the product groups and covers various aspects of the grid which are installed in public area of the traffic light to 1000mm opening, except for surface boxis, which are also located in our production program is worth the norm EN 124, while the drainage program in objects norm EN 1253. These standards prescribe in detail the concepts and terms related to this area of application, materials, conditions of production and quality assurance of these products, constructive basis, recommendations for installation, testing and monitoring.
It is important to note that the modern system of drainage requirements to efficiently and quickly collect the special overall precipitation and other surface water. Since the water has collected so often the proportion of contaminated certain harmful content, it is important that the whole system is hermetic and waterproof, than gathered water easily and without loss brought to a place where all the pollution and also completely eliminated, so that the system was returned only pure water. Because of the tightness is very important, and the entire design and construction of all elements of the whole system should be implemented in accordance with applicable regulations and standards listed in this description.
