Rainwater Infiltration in Bad Nauheim

Installation and maintenance of infiltration trenches

Abfluss-AS is your reliable partner in Bad Nauheim for all services related to rainwater infiltration. The problem of land sealing has become increasingly visible across the country, with rising costs for drinking water and wastewater treatment and a higher risk of flooding. Particularly for new buildings, but also for conversions and renovations, the issue of rainwater infiltration has become critical.

We offer localised, decentralised infiltration methods, such as infiltration troughs, which provide a near-natural way of dealing with collected rainwater. Such new technology is increasingly being promoted by regulators as a way of protecting the environment and cutting costs.

What is decentralised rainwater infiltration?

When rainwater that has not been polluted with harmful substances infiltrates directly onto the property, this is referred to as “decentralised rainwater infiltration”. The technical issues in this context are regulated by the DWA-A 138 worksheet.

What is a storm drain?

An infiltration trench is an underground trench in which rainwater can infiltrate. Infiltration trenches are mainly planned because of limited space and the relatively simple realisation.

Infiltration trenches can be installed under paved paths and areas accessible by lorries. They can be combined with other techniques, e.g. above-ground depressions (swales).

Amendment of the Water Resources Act

According to the amended German Water Resources Act (WHG), more rainwater is to be infiltrated instead of being drained into the sewage system as was previously the case. According to § 55 para. 2 WHG, the mixing of rainwater and wastewater is to be avoided. In fact, this regulation means the end of the principle of mixed sewerage.

Furthermore, rainwater infiltration systems are increasingly prescribed in development plans. Modern infiltration trenches offer various advantages over classic rainwater infiltration (troughs, gravel):

  • High storage and infiltration capacity (only 30% of the gravel volume is required for the same capacity).
  • Less land required (less excavation)
  • Hardly any restriction on surface usability (in contrast to swale infiltration)
