Rainwater Infiltration in Limburg

Installation and maintenance of infiltration trenches

Abfluss-AS offers rainwater management Services in Limburg: Innovative Infiltration Solutions. In the wake of escalating land sealing consequences throughout Germany, which manifest in rising drinking water and wastewater expenses, as well as heightened flood risks, effective rainwater management has become crucial. This is especially relevant for new construction projects, as well as for renovation and remodeling endeavors.

Embracing the latest advancements in eco-friendly technologies, we specialize in the near-natural handling of rainwater. Local regulatory agencies are increasingly mandating decentralized onsite infiltration methods. Our services include the expert installation and maintenance of infiltration trenches, aligning with these environmental and regulatory standards.

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)
