For combined rainwater detention and rainwater harvesting

To guarantee retention of rainwater, a delayed drain is fitted in the channel with 0.05 to 2.0 l/sec. depending on the customer’s specifications and the retention or harvest volumes. In the event of heavy rainfall, the water level in the cistern rises above the max. water level (short term) and is drained into the channel at delayed speed using a floating drain choke.
This relieves the channel and the treatment works.
The water level can rise to the emergency overflow and sinks slowly back down again after the rain to the long-term max. water level. This rainwater can then be harvested.
We also construct and supply individual, special solutions.
This special type of rainwater harvesting is prescribed or subsidised in many communities.

Advantages

Thought-out in every detail

Low installation depth

The minimal installation depth saves you time and money during installation.

Low weight

Tank installation made easy! The significantly lower weight of GRAF products compared to steel or concrete cisterns makes transport and installation easier.

Optionally with second tank dome

The GRAF XXL tank can optionally be equipped with a second tank dome.

Retention Plus

A combined retention/rainwater utilisation saves up to 50 % drinking water. The water can be used for garden irrigation, cleaning work and in the house also for flushing toilets and washing machines.

Dome opening with stainless steel profile

Dome opening with stainless steel profile for high fitting accuracy and mounting safety.

Individual connections possible

Flexible connections possible according to customer requirements on the tank dome up to DN 300 or on the end face up to DN 200.

Ready for connection

With GARANTIA tank systems, the connection seals are already pre-drilled and lip seals are pre-assembled. This saves time and therefore costs during installation.
