Remediation Works and River Water Quality

Message from Sanctus Ltd

In order to make excavations safe for the remediation, we are permitted to abstract groundwater for discharge to the River Lea. These operations are permitted by the Environment Agency.

Prior to discharge, the groundwater goes through our bespoke onsite water treatment system which ensures the water quality meets the criteria set by the Environment Agency. This system comprises a Siltbuster, oil/water separator and granular activated carbon pods.
