Resilient Infrastructure and Operations

Operational efficiency is the driving force that animates MPIC’s sustainability vision into action. As regulated companies in their respective concession areas, our companies enjoy a captive market of millions who rely on us for vital services. Because they serve as lifelines to a mass customer base, our companies’ ability to maintain high operational efficiency levels while respecting societal and planetary boundaries is paramount to MPIC’s sustained growth and longevity. Our interests in power, water, and transport infrastructure development are primarily geared toward national economic progress, but they also come with an equally compelling interest in creating environmental and social values.

Key Initiatives

Power Restoration Project and Relief Operations

Meralco serves as a core member of the Department of Energy’s (DOE) Task Force on Energy Resiliency. Through Task Force Kapatid, a group organized by electric cooperatives, Meralco assists other electric companies in restoration and rehabilitation efforts in cases of disasters and calamities.

Maynilad’s Emergency and Preparedness Plan

Maynilad created an Emergency and Preparedness Plan, which aims to establish adequate emergency response per organizationand per appropriate level for different facilities. The plan also seeks to build up capabilities, identify and maintain requirements for emergency response, and ensure that all employees are prepared for any emergency situation.

Technical Upgrade of the La Mesa Treatment Plant

Maynilad pushed through with the rehabilitation of the La Mesa Treatment Plant 1 and 2 with the main goal of improving the treatment efficiency of these plants by increasing the capacity of these plants to treat high turbidity water without affecting the output-treated water production. This P7.9 billion project includes the construction of additional facilities and installation of additional equipment inside these treatment plants. This project also includes rehabilitation of the existing sedimentation and filtration basins, and installation of other features such as a system to handle high turbidity raw water and structures intended to withstand a 7.2-magnitude earthquake.

Upgraded Facilities in La Mesa Treatment Plant (LMTP)

Maynilad recently finished the rehabilitation of eight sedimentation basins, 16 filters, and a new sludge treatment facility at LMTP 1. The new upgrade will see a reduction in the use of chemicals in the treatment process through improved filtration and sludge treatment, the replacement of motorized mixing with hydraulic mixing, installation of solar power, and improvements in automated processes.

Establishment of Water Quality Forecasting Tool

Maynilad established 10 monitoring points within a 5-km radius of the Laguna Lake as part of efforts to monitor and forecast raw water quality. y. The early detection of raw water impurities allows enough time to prepare adjustments within the treatment plant to minimize reduction in plant output.

Establishment of Habagat Protocol

The Habagat Protocol outlines the coordinated preparation and response of operations before and during the onset of the typhoon (habagat) season, which causes severe water quality issues in our raw water sources. It includes a communication matrix involving all critical sections of Maynilad’s organization and their direct responsibilities in the implementation of the prescribed supply rotation schemes along with the timely release of water service advisories of affected areas.

Structural integrity audits: Toll Roads and Light Rail

MPTC fortifies all of its infrastructure based on recommendations of their Project Management, Asset Management, and Compliance & Business Excellence Division. This environmental group monitors Identified Environmental Impacts for every project and implements necessary mitigation measures.

No incidents of defect or safety-related rework costs were incurred in 2020. MPTC also incorporates operational-phase energy and water efficiency considerations in its project planning and design. The company also has zero backlog for hydro-carbonated, renewable energy and non-energy projects associated with climate change mitigation. They have invested in green buildings and garnered LEED Certifications for its MPT South Hub.

The 36-year-old LRT-1, previously a state-owned infrastructure, has been upgraded with the installation of stronger parapets, concrete repairs, sandblasting to remove corrosion, repainting, installation of new collision dampers to protect bridges from ship collision, and installation of noise dampening barriers to address the persistent complaints from nearby neighborhoods and establishments.

Effluents Management

In 2020, total water discharged by the MPIC group is 1,306,538 ML, of which 94% is discharged by GBP to seawater bodies while the other 6% is discharged by Maynilad back to sea and surface waters. LRMC completely zeroed out its water discharge through the treatment and recycling of 459 cubic meters of wastewater.

Maynilad maintains and operates its septage to prevent the pollution of waterways and bodies of water. Maynilad has 612 interceptor box systems (formerly called combined sewer overflows) which collect and transport all of the sewage that flows into them to a wastewater treatment facility. The average volume of wastewater treated by Maynilad in cubic meters per day (CMD) are as follows: Sanitary Sewer – 633 CMD (Sanitary sewer average volume does not include March to June 2020 due to ECQ), Storm water – 78,172 CMD, Combined Sewer – 119,469 CMD.

Their wastewater treatment capacity located in 100-year-old flood zones is 664 MLD. The majority of the wastewater treatment facilities operated by Maynilad are unmanned and remotely operated by teams of roving engineers via a Central Control Room. Using 24/7 real-time monitoring, the teams make sure that all facilities are operating at optimum condition and are ready to convey and treat wastewater generated by customers whether there is a storm or flood in the area.

Wastes Reused, Recycled, and Repurposed

In 2020, total waste generated by MPIC was 103,073 metric tons (MT), whereby varying trends of waste generation were observed across operating companies. GBP, NLEX, and LRMC have an overall decrease in the waste generation of combined hazardous and non-hazardous waste. For CAVITEX, though its waste increased to 69%, it diverted from disposal 86% of its nonhazardous waste through its recycling program. The head office of MPIC incurred increased waste generation but has diverted 100% of its total waste from disposal also through reuse and recycling.

This year, a total of 2,022 MT of wastes was diverted from disposal and was reused, recycled, and repurposed either by our operating companies or by our thirdparty waste treaters. Total non-hazardous waste diverted is 1,604 MT and total hazardous waste diverted is 419 MT.

Total Ban on Single-use Plastics

All single-use plastics are banned from all Meralco offices, premises, and facilities since 2019. Aside from reducing the amount of plastic going to water bodies and landfills, Meralco aims to educate its business partners and teams on how to use and dispose plastic responsibly. Through this company-wide ban, Meralco employees and suppliers have collectively avoided over 150,000 kg of single-use plastics equivalent to more than 15 million plastic bottles.

GBP ConVan

Built by upcycling six units of 20-foot cargo containers, leftover scraps, and other construction waste from PEDC’s 150-MW expansion project, the ConVan is a 12-room facility which now serves as an extension of the power plant’s guesthouse.

Sewer Rehabilitation Project in Central Manila

Maynilad announced in October 2020 that it is rehabilitating the Central Manila Sewerage System (CMSS) at a cost of P969.14 million as part of its long-term wastewater management initiative. The project will upgrade approximately 9,600 linear meters of sewer lines within 30 barangays in Sta. Cruz and Malate, boosting the sewerage system’s reliability and capacity to accommodate a larger volume of wastewater. Targeted for completion in June 2021, the project will help to sustain sewerage coverage expansion in its concession area, which ultimately will lead to less pollution of the Manila Bay.

Building Information Modeling and Distributed Control System

Maynilad’s Putatan Water Treatment Plant 2, which sources raw water from Laguna Lake to provide potable water for Maynilad customers in the south, has been featured as a model facility for the effective adoption of a Distributed Control System (DCS), a computerized realtime control system that combines multiple complex processes through a single automated platform. Maynilad has also been using Building Information Modeling (BIM), an integrated 3D-model-based system that yields a digital representation of the complete physical and functional characteristics of a building or facility.

For its adoption of these two technologies, Maynilad received the 2020 Philippine Enterprise Innovation Award from the Asia IoT Business Platform (AIBP).

Advanced Distribution Management System

Meralco has upgraded its outage and distribution management systems to help decrease the duration and frequency of power interruptions. First adopted in 2016, the Advanced Distribution Management System (ADMS) is an intelligent software that supports the full suite of outage management, distribution management, and optimization functions.

Fault Location, Isolation and Service Restoration (FLISR) is a component of ADMS that isolates the location of outages and reroutes power to as many customers as quickly as possible. With real-time network information, Meralco is better able to detect and respond to outages.

Automated Train Operations Management System

Developed internally by LRMC employees and adopted since 2018, the Automated Train Operations Management System (ATOMS) enables LRMC to efficiently optimize resources to meet LRT-1 customer needs for more trains, more trips, shorter queuing time, and more comfortable and faster rides. In addition, management is able to surpass 20 key performance indicators monitored by the government.

Automated Train Operations Management System Transition to RFID

MPTC has been pushing the use of radio frequency identification (RFID) stickers as part of a long-term strategy to go contactless and do away with cash transactions in all of its expressways. By eliminating cash transactions, all barriers at toll plazas will be eliminated as well, making passage at toll roads three times faster.
