We incorporate tree pits into the overall rainwater management plan. It is important to make good use of rainwater – to ensure healthy urban greenery all year round.
The impacts of climate change must be taken into account in construction. Construction is an investment spanning decades, and so the local effects of these changes – such as heavy rainfall events – must also be considered.
Flood protection is the top priority. At the same time, the question arises as to what solutions exist for distributing water resources during periods of drought. In the debate surrounding this growing challenge, the principle of the sponge city is frequently mentioned.
Urban trees help to mitigate the effects of climate change. This will significantly increase their importance in the coming years. It is therefore important to integrate tree pits as plantable retention spaces into the rainwater management concept right from the planning stage of new urban developments or urban regeneration projects.
This system ensures a modern irrigation of tree pits. It consists of the DRAINFIX CLEAN filter substrate channel, which collects and filters rainwater and directs part of the purified water to the plantable retention area. The remaining water is channelled into the DRAINFIX BLOC infiltration unit, where it can seep away. This saves precious drinking water. The concept is ideal for tree-lined avenues and confined spaces.
This option allows for the direct watering of several green spaces using treated rainwater from the filter substrate channel via a single system. The tree pit can be built over and used as a car park or footpath. The concept is suitable for green spaces with several trees.
Rainwater from traffic areas is collected and purified in DRAINFIX CLEAN filter substrate channels. The clean water flows directly into the tree pit or is diverted to a rainwater tank for temporary storage. Excess water seeps into DRAINFIX BLOC infiltration units and can seep away there. In this way, rainwater can be retained and used for irrigation during dry periods – ensuring healthy urban greenery.
To assist with the irrigation of tree planting sites, HAURATON provides the digital tool TREEPILOT.

Temporary watering carried out by council staff incurs high costs (lorries, fuel, maintenance, staff wages). This raises the question of how much of the water actually reaches the roots through the dry soil. Furthermore, this method of watering generates unnecessary CO₂ emissions, noise and traffic disruption.
Why should rainwater be drained away, whilst drinking water is laboriously transported to the site and used for watering?
Tree watering bags can detract from the urban landscape. They are only suitable for small trees. Here, too, the question arises as to how much water actually reaches the roots efficiently. Furthermore: How is operational safety ensured? Who is responsible for ensuring that the bags contain neither too little nor too much water?
The Soil Guard continuously monitors soil moisture and shows how much water is available to the plants. This enables early detection of drought stress or waterlogging and allows for the targeted planning of irrigation measures. This supports water use tailored to actual needs and promotes the vitality of trees and plants.
