Stormwater infiltration and attenuation
Efficient - safe - digital, with us your project will be a success.
The direct effects of increasing land sealing are noticeable everywhere. Most noticeable are rising costs for stormwater drainage as well as flood damage. Over the last few years, a process of rethinking has taken place. The old goals of drainage and centralized treatment of stormwater are being revised. The idea of decentralized infiltration, i.e. the infiltration of excess rainwater as far as possible where it occurs, is becoming more and more prevalent and is becoming an essential component of sustainable stormwater management - for the benefit of citizens and the environment.
Increasingly, decentralized infiltration and attenuation on site is also being demanded by the authorities. More and more cities and municipalities are promoting these measures, in part through more favorable wastewater charges, exemption from the levy for rainwater or a subsidy for unsealing and infiltration measures. With our complete range of products, we provide you with a unique all-round service for the success of your project.
Store heavy rain and simply feed it to the groundwater where it occurs. There are various options for the infiltration of stormwater from sealed surfaces. INTEWA offers you complete solutions for infiltration by infiltration trenches and trough infiltration trenches.
Store heavy rainfall and discharge it into the drainage system in a throttled manner. Stormwater attenuation is required when a discharge restriction into the public drainage system is specified. The discharge restriction results in a necessary retention volume to temporarily store heavy rain events on the property. The necessary buffer volume can be represented above ground - usually as a basin - or below ground.
Infiltration trenches become digital
With the innovative INTEWA CONNECT technology, these systems can now be monitored remotely for the first time worldwide. Plant operators are informed about sludge level, filter flow and discharge capacity at any time via the INTEWA cloud server. This new remote monitoring guarantees the flawless operation of the system and pays for itself in just a few years.
DRAINMAX tunnel trench
Our core stormwater management product consists of 1.6 m³ capacity, plastic trays that create a hollow volume of any size in the soil. It can be used for infiltration, attenuation or storage of water.
- Truck loading capacity and DIBt® approval
- Best price per m³
- Easy installation
- Only system with flushable bottom
Maintenance at any time
The entire system around our DRAINMAX tunnel drain offers a reliable and easy-to-use maintenance concept. Starting with the easily flushable tunnel elements, up to the digital monitoring, which can be realised with only a few sensors.
Prefiltration according to DWA and DIBt
Depending on the dirt input of the connected areas, different cleaning measures are required before infiltration or discharge into the sewer or receiving water. In addition to cost-effective sedimentation and filtration chambers, we also offer systems for the treatment of heavily polluted road runoff.
