100% RETENTION
Retain rainwater and evacuate to the network at a rate regulated by a flow limiter.
The retention capacity (from 1'500 litres to 16'000 litres) and the regulated discharge rate are defined according to the place of construction and the type of housing that needs to be equipped.
For retentions above 10'000 litres, it is preferable to install Rigofill® modules (retention / infiltration modules). Indeed, from 10 m3, it is financially profitable to install these elements.
More and more, the municipalities impose those tanks in order to reduce the discharge of rainwater into the natural environment. The retention capacity and the regulated discharge rate (which depends on the municipal General Water Evacuation Plan) are mentioned in the specifications.
These tanks are especially recommended when:
- the storm basins are saturated
- the networks are overloaded
- infiltration into the soil is too slow
- the water table is shallow

Retain rainwater in its retention compartment and evacuate to the network at a rate regulated by a flow limiter.
Keep a volume of rainwater for personal use for the garden.
1. Normal flow to the network without retention
2. Flow with regulator without float
