Septic tanks provide the most common form of sanitation throughout Metro Manila. Around 85% of the
households in the metropolis were reported to have septic tanks in the year 2000 Census. The objective of this
component is to collect and treat septage in the more westerly parts of the East Concession Zone, specifically
those areas within the National Capital Region (NCR). It is currently estimated that there are 544,000
household users of individual septic tanks (ISPs), which is equivalent to 2.3 million residents.
To treat septage collected from ISPs, two (2) Septage Treatment Plants (SpTP) are proposed for construction.
The North SpTP was initially planned to be located in the vicinity of the Payatas Solid Waste Dump Site in
Quezon City, however, due to difficulties in acquiring land in the area, an alternative site was identified in
Barangay Gitnang Bayan II in San Mateo, Rizal. The new site will still primarily serve Quezon City,
Marikina and San Juan and will have a capacity of 586 m3
/day. The South SpTP will have a capacity of 814
m3
/day and is proposed to be located within the FTI mixed-use industrial complex in Taguig. The South SpTP
will primarily serve the cities of Mandaluyong, Pasig and Makati.
This component will also include the procurement of equipment for septic tank desludging, and septage
transport, treatment, and safe disposal.
