As part of its flagship advocacy “Toka Toka”, East Zone concessionaire Manila Water encourages its customers to take advantage of the monthly desludging service offered by the Company.

Toka Toka is the first and only environmental movement in the Philippines that advocates proper management of wastewater in every household as an important share (or "toka") in reviving our rivers and waterways.

Before the scheduled desludging in the barangay, Manila Water, through its Advocacy Managers and Service Area representatives, leads an information, education and communication session to discuss the importance of regular desludging of household septic tanks to the health of the community and the environment, and how the collected wastewater is treated in Manila Water’s Septage Treatment plants (SpTps), ensuring it passes the stringent government standards set for effluent before being discharged back to various water bodies in its service area.

Toka Toka also calls for the practice of solid waste and segregation and connection of all households to a proper sewer line.

In October, Manila Water’s desludging caravan will go around sixty-seven (67) barangays in the East Zone to provide septic tank siphoning at no additional cost.
