Ayala-led utility firm Manila Water Corp. is spending P115 billion until 2037 to boost its sewerage coverage within its concession area.
To complete its sewerage program until 2037, Manila Water needs to lay around 500 kilometers more of pipes in public and private roads to capture wastewater from households and establishments in the east zone to convey to sewage treatment plants (STPs).
“Since 1997 when we took over the East Zone, we have spent P38.5 billion on our wastewater programs from collections of only P36.9 billion. So, we have excess investments of P1.6 billion and we expect this trend to continue,” said Manila Water COO Abelardo P. Basilio.
Part of the capital budget will fund the construction of system projects covering 11 sub-catchment areas. Seven projects are set to commence until 2022 translating to an investment of P 38.4 billion while the rest will begin construction from 2023 onwards.
The sewage treatment plants to be built for these system projects are designed to cumulatively collect and treat up to almost 950 million liters per day of wastewater from 7.5 million population in the East Zone by 2037.
The investment also covers the rehabilitation of existing sewer lines and the upgrade of currently operating STPs to comply with the new standards by the DENR for biological nutrient removal in the wastewater treatment process.
For ongoing wastewater infrastructure projects, nearing its completion is the Ilugin sewage treatment plant to serve the sub-catchment area of North and South Pasig. Targeted to be operational by 2020, the facility is seen to serve 700,000 in terms of population once completed.
Other projects that are expected to commence soon are the Mandaluyong West and San Mateo-Rodrigue sewerage system projects, which will eventually serve more than 1.3 million population by 2037.
Manila Water currenty operates 38 STPs and 2 septage treatment plants with a total capacity of 310 MLD.
