VELIKI POTOK FLOODWATER RETENTION BASIN
The retention basin with a volume of 549,143 m3 protects the people living in the Municipality of Grosuplje from being reached by 100-year floods.
Veliki Potok retention basin is a dry floodwater retention basin, which means that the water level behind the barrier only increases during floods. The floor drain is regulated using a sluice gate, and nature conservation measures require that a minimum water flow must always be ensured in the watercourse under the barrier. The ground barrier of the retention basin is 220 m long, with a maximum height of 16.65 m.
THE RETENTION BASIN REDUCES THE FLOOD RISK FOR THE MUNICIPALITY OF GROSUPLJE.
