Rainwater management and surface water treatment Rainwater management

Usage Percolation Evaporation Retention Treatment Throttled discharge For this reason, decentralised systems for retaining and treating precipitation water are increasingly being installed as part of the construction of industrial parks, traffic areas and residential buildings. This water is treated before being discharged in a controlled manner into a body of water or allowed to percolate into the ground – an economical and also environmentallyfriendly alternative to treating the water in municipal sewage treatment systems together with other waste. Rainwater use is a special form of...

4 Rainwater management Day in and day out, enormous quantities of drinking water are wasted – precious water, which has to be painstakingly treated and must be transported to households at great expense. A 5-person household can save as much as 100.000 litres of drinking water each year. Rainwater storage tanks with integrated filters Dirt particles such as leaves, petals and sand can have a negative effect on rainwater. Rainwater should thus be thoroughly filtered as a matter of course before it reaches the storage tank. A distinction is made between the integrated filters in the rainwater...

Mall filter shaft Mall Monsun XL rainwater centre Rainwater management 5 Large-scale rainwater use – Mall environmental systems has extended the range of its large-scale installations to include the Monsun L duo and XL rainwater centres. Our rainwater storage tanks made of pre-cast concrete parts come complete with control systems and pump equipment. These new largescale Mall systems are characterised by reliability and operational safety. Building services and rainwater The demand from commercial and industrial operations for service water circuits to use in cooling, fire protection,...

OPTIONAL: Backflow monitoring including empty DN 100 conduit for supply lines DN 100 inlet 2. Filter basket Type MVS 450 - 650 Regardless of how they are designed, roofs and roof drainage will always feed back into the natural water cycle. According to the DWA-M 153 information sheet, run-off water from uncoated roof coverings made of copper, zinc or lead is categorised as heavily contaminated and thus requires special treatment. Overground percolation of this water is tolerated, but often cannot be implemented because of the large amount of surface area required. Mall metal-roof rainwater...

Mall water containers for fire fighting as per DIN 14230 Water containers for fire fighting are covered underground storage tanks with one or more supply points to supply water independent of the drinking water network. On-site supply of water for fire fighting The provision of sufficient extinguishing agents is one of the most important preventative fire protection measures. In new development projects, a decentralised water containers for fire fighting allow for smaller crosssections in the drinking water supply. Each container, complete with all accessories (e.g. suction pipes with fire...

Rainwater management 9 Mall Sico rainwater storage tank, combined percolation and use patented The ideal combination The Mall Sico rainwater storage tank system enables the disposal of excess rainwater in the soil and groundwater. Run-off rainwater is filtered and collected in an underground concrete cistern. The stored water is used as service water in the house or for watering the garden. Excess water is routed to the surrounding gravel areas and percolates from there into the ground or into the groundwater (it may be necessary to inquire about permission requirements). Advantages n...

10 Rainwater management Protection against backwater with Monsun L plus in conjunction with the Mall Monsun rainwater centre Utility model granted With the Monsun L plus, we have transformed a simple rainwater use system into a multifaceted, state-of-the-art rainwater man - agement system. According to DIN 1989-1 “Rainwater harvesting systems – Part 1: Planning, installation, operation and maintenance”, all systems must be equipped with a frostproof riser loop if the overflow is not connected to a combined sewage system in a backwater-proof manner. Wherever fees are levied according to the...

Rainwater management 11 n Combined sewage system: Reduced load on the sewage treatment system and extension of the upstream rainwater retention installations through additional buffer volume n Separate sewage system: Reduction of peak run-offs from torrential rainfall to reduce the load on receiving waters n Percolation: Pollutants entering the system are retained through fine filtration and sedimentation in the storage tank – for soil and groundwater protection – no accumulation of sludge in the percolation areas – for uniform percolation water inflow – smaller dimensions for the...
