Requirements for rainwater management in residential and commercial buildings
Several factors come into play when choosing a suitable drainage system for residential and commercial buildings. The interaction of precipitation, water runoff, flooding and building development must be taken into account. In addition, various standards and guidelines for dealing with rainwater must be observed (DWA M-153, DWA A-102, DWA A-138, EN 752 and others). In addition, the regular modernisation and renovation work requires a technically feasible, and at the same time, cost-efficient solution.
Requirements for new residential buildings and areas
Residential buildings are not only a place of retreat and the centre of life for many people, they also shape the cityscape. Therefore, the following requirements must be taken into account when planning the rainwater management of existing residential buildings or new construction areas:
Further requirements:
Protection of the building:
The building must be continually protected from precipitation, standing water or pressurised water. Accumulating precipitation must be safely and reliably drained away.
Aesthetic integration with the building concept:
Every building is individual and has its own character, which must be emphasised. The drainage solution must therefore be functionally and aesthetically integrated as part of the building’s architecture and urban environment.
Barrier-free entrances and exits:
To ensure that all living areas are accessible without restriction, passageways and thresholds are increasingly being planned and implemented barrier-free. Of course, the building structure must also be protected from precipitation.
“When planning and implementing drainage solutions for residential & commercial buildings, many requirements must be taken into account. I am happy to support you in all project phases – from the drainage application to the hydraulic calculation and installation.”
Requirements for commercial buildings
Commercial buildings also place high demands on drainage. In addition to safe solutions for heavily trafficked commercial areas, watercourse and groundwater protection also play an important role.
Solutions for comprehensive rainwater management for residential and commercial buildings
There are two different solutions with various possible combinations for planning a comprehensive rainwater management concept for residential and commercial buildings.
Solution 1: Drainage channel without filter substrate
-
A revitalised soil zone allows large amounts of water to be collected, temporarily stored and infiltrated. Pollutants are bound in the soil. Disadvantage: Large space requirement, high maintenance effort, little control over the cleaning performance and heavily polluted soil.
-
By inserting a technical filter into the green swale, the water can be efficiently pre-cleansed. The maximum 30 cm high filter layer in the swale retains the pollutants on the surface and the swale can be made significantly smaller. In addition, it requires less maintenance.
Solution 2: Drainage channel with filter substrate
Heavy-duty drainage channel with filter substrate integrated into the traffic surface is installed at the end of the parking row or between two parking spaces. This creates a visual separation and can still be driven over and walked on.
-
Rainwater from traffic areas can be used, among other things, to irrigate tree pits. Due to the pre-cleansing in the filter substrate channel, the rainwater can be fed directly to the plants.
-
In combination with the DRAINFIX BLOC 300, the pre-cleansed water can seep into the ground. Due to the possible retention volume in the channel, the volume of the infiltration element can be smaller than that of other systems.
-
Pre-treatment of rainwater ensures that it can be easily stored and reused.
