We strive to ensure that 30% of the drains in the municipalities of the Metropolitan City of Milan are cleaned every year, in order to complete the programme every three years.
We agree on each intervention with the municipal administrations on the basis of the critical issues and the priorities identified.
Our work doesn’t stop there: we also see to carrying out the extraordinary cleaning operations necessary for any critical situations reported by the municipalities.
Drains are the essential grid manholes to ensure urban drainage: they intercept rainwater and street washing water and convey them into the sewer network, prevent flooding and avoid stagnation along the roads.
The drains are cleaned every year, completing the cycle every three years.
