The Discharge Permit Unit, DPU, is an entity within the Water Services Corporation that enforces the national Sewer Discharge Control Regulations, S.L. 545.08
This is a joint effort between WSC and commercial entities to control the levels of industrial contaminants entering the sewer system through permitting, inspections, monitoring, and enforcement.
Households are expected to observe the local legislation pertaining to discharges into sewer, S.L. 545.08 as stipulated in the WSC Customer Contract. This is of vital importance to make sure that the public sewer network managed by the Water Services Corporation is kept in good working condition to keep serving the Maltese public.
Did you know that WSC spends about € 3 Million per annum on clearing of blockages and cleaning of waste water pumping stations?
