Philippines : Angat Water Transmission Improvement Project
The Project will secure raw water supply to the 13 million inhabitants of Metropolitan Waterworks and Sewerage System (MWSS) service area, through the rehabilitation of the Angat transmission line. It is estimated that currently each day about 800,000 cubic meter (m3) or 20% of the total potential capacity of raw water is lost due to leakage of the aqueducts. The main components of the Angat transmission line are as old as 50 years, in poor condition, and not in compliance with structural and seismic requirements, risking the partial interruption of Metro Manila's water supply. The proposed financing modality is a Project loan.

| Project Rationale and Linkage to Country/Regional Strategy | Provision of water supply and sanitation in Metro Manila (Manila) is the responsibility of MWSS, a government-owned corporation. In 1997, it awarded two concession contracts to private firms for water distribution. MWSS retained responsibility for bulk water supply. The privatization of the distribution services brought about significant improvements in the delivery of water supply services. The serviced population has doubled since 1997, of which more than 90% have 24 hours access. The nonrevenue water level (NRW) of over 60% in 2002 currently ranges from 10 to 40%. MWSS's capacity to fulfill its responsibility of ensuring and securing the availability of raw water to the concessionaries needs to be strengthened by: (i) rehabilitation of the raw water transmission system; and (ii) adopting a comprehensive water safety, risk- and asset management system. Rehabilitation works. Manila's main water supply source is the Angat reservoir, which provides about 97% of Manila's water supply. Water from the reservoir is conveyed through a system of tunnels and aqueducts to water treatment plants in Manila. The treated water is then distributed to households, businesses, and industries in Manila, and parts of Cavite and Rizal. The demand on the Angat water source is about 4.48 million cubic meter per day (m3/day), and is slightly decreasing from 2010 to 2015, as a result from the very successful NRW reduction programs of the concessionaires. However, following 2015, the demand will increase rapidly due to expected water supply area expansion and population growth. The demand is expected to increase by 38% in 2025 to 6.16 million m3/day. |

| Summary of Environmental and Social Aspects | |
|---|---|
| Environmental Aspects | The project is categorized as 'Category B', given that it is not expected to cause irreversible adverse environment impacts. An environmental impact screening was carried out and an initial environmental examination (IEE) report was prepared. The bid document includes an environmental management plan (EMP) that ensures mitigation of identified environment impacts during construction. The IEE follows a process that complied with ADB's Safeguard Policy Statement (SPS 2009) with supporting justification for Appendix 1, Section 8 regarding protected areas, Philippine laws and regulations, and compliance with the same. The additional financing is categorized as 'Category B' for environmental safeguards. The initial draft of the DED-based IEE/EMP for AQ7 was submitted to ADB and is ongoing review. IEE/EMP will be disclosed following ADB clearance. |
| Involuntary Resettlement | The original project is categorized as 'Category C', given that there is no expected physical and/or economic displacement and/or land acquisition. The construction and use of the tunnel, which is situated 50 to 200 meters (m) below the ground surface, do not impose any safety risks to the existing assets, establishments, surface structures, and land use. The legal rights of the land above the tunnel belong to the MWSS. The additional financing is categorized as 'Category B' for involuntary resettlement. Even though no land acquisition is needed, 20 structures inside the designated 25 m wide construction area and MWSSs existing right of way will be permanently affected (demolished prior to construction). Losses of residential and commercial structures and crops will be compensated at replacement costs. The updated Resettlement Plan has been submitted, cleared, and disclosed in the ADB website in April 2023. |
| Indigenous Peoples | The original project is categorized as 'Category B' because the planned contractors work area of 1 hectare is part of the protected Ipo watershed area, which overlaps with an area claimed as ancestral domain by the indigenous Dumagat people. The land is free from any structures, establishments, and vegetation. The projects impact is limited to disturbances during construction. Consultations were held with the indigenous peoples communities living along the tunnel and an indigenous peoples plan (IPP) was prepared, outlining measures to mitigate these disturbances. The IPP was updated following the completion of the DED and impacts and updated socio-economic profile of the Dumagat IPs living in the communities near the project area. Consultation meetings with the National Commission for Indigenous Peoples (NCIP) were held to share the plan proposals and implementation strategy with the Tribal Councils. In line with the Free, Prior and Informed Consent process, a Resolution of Consent was issued by the Dumagat Indigenous Cultural Community (ICC) on 13 December 2019 and the Memorandum of Agreement (MOA) between and among the MWSS, the Dumagat ICC of the Kabayunan Ancestral Domain Norzagaray, Remedios Trinidad and the NCIP was signed on 17 December 2019. Meaningful consultations were implemented with the indigenous peoples in accordance with the SPS. The MOA is an important requirement in securing the Certificate Precondition through the NCIP En Banc Resolution. The following are provided for in the MOA as negotiated: livelihood support, scholarship grants, sanitation facilities improvement, tribal centers construction, ambulance, solar panels, fingerlings, and motorized boats, among others. The PhP20 million to fund the implementation of this community development support program for five (5) years have been transferred to the IP account. The additional financing is categorized as Category C for Indigenous Peoples. No indigenous peoples and ancestral domain areas will be affected by the additional financing. As the implementation of the MOA will be beyond the period of the original financing, it was agreed that the additional financing will cover the monitoring of the MOA implementation. |
