Wastewater Discharge Permits Remain a Key Requirement for Philippine Facilities

DENR-EMB • COMPLIANCE UPDATE

The Wastewater Discharge Permit (WWDP) remains an important regulatory requirement for facilities discharging treated wastewater. In 2026, EMB-NCR continued bringing WWDP and other environmental permitting services directly to businesses through its EMPOWER permitting activities in locations including Las Piñas, Parañaque and Pasig.

For STP owners, compliance should therefore be treated as part of normal plant operation—not something addressed only when a permit is due for renewal.

Routine sampling, laboratory results, operator records, equipment maintenance and proper documentation all support a facility’s compliance program.
