Proven units and systems for Rainwater use The use of rainwater has become an established element in building services for houses, especially since the publication of the DIN 1989 series of standards, Part 1 to 4. The fact that groundwater reserves are permanently under threat and that sewage treatment plants and sewage systems can’t keep up with precipitation levels has lead to increased recognition of the importance of rainwater management. Experience and expertise you can depend on As early as 1979, we began carrying out pioneering environmental and commercial work with the monolithic...

Rainwater use for engineering, commercial and industrial premises Commercial and industrial companies generally have large water needs and large roof surfaces too. If this is the case, the prerequisites are in place to use rainwater in the company. Wide range of applications for rainwater Alongside use in production, rainwater can also be used as service water in other areas. This leads to significant savings on drinking water and wastewater rates, which are rising all the time. This is particularly true where additional precipitation charges are applied based on the amount of paved or...

Use, percolation and retention of rainwater Rainwater storage tank Reto (Utility model granted) Rainwater tanks not only store water for use, they also retain rainwater which would otherwise burden the sewage system with undesirable peak volumes. Not enough attention is generally paid to this retention effect in private use. This behaviour is altered with Reto rainwater tank, an ingenious system which combines usage with retention. In the same manner as public rainwater retention basins, this tank repeatedly provides free retention capacity for the next precipitation. Its function in...

Sedimentation systems The incoming water is directed by the guide baffle to form a circular stream which flows tangentially to the container; a rotating body of water forms in the an- nular gap between the container's outer wall and the central pipe. Dirt particles settle at the bottom Light substances are retained in the upper area. An additional containment area is provided for light liquids if accidents occur. Technical data ■ Classification as per information sheet ■ Connectable reduced area of 260 to 8,200 nr ■ Permitted through flow volume 3.9 - 620 l/s ■ Optional: bypass with...

Systems for precipitation water treatment Legislation on the management of water resources prohibits mixing precipitation and wastewater as per § 55 paragraph 2. At the same time, it is demanded that rainwater, depending on where it is produced, is discharged into a body of water or the groundwater without any further negative effects. Mall rainwater treatment systems prevent any negative effects to traffic, industrial, commercial and roof areas with metal surfaces. Need for treatment (annual average efficiency of the plants) is determined using the DWA leaflet DWA M 153. The result of the...
