To put things in perspective, posted below is an excerpt from the company’s announcement. Some parts in boldface…

West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) has inaugurated the new Tunasan Water Reclamation Facility (WRF) in Muntinlupa City—its 25th wastewater treatment facility—expanding sewerage coverage in the south and supporting long-term efforts to protect Laguna de Bay.

Located along Buendia Street in Barangay Tunasan, the new WRF can treat up to 20 million liters of used water per day (MLD). Wastewater from Magdaong, Bubogan, and Tunasan Creeks is conveyed through 1.4 kilometers of sewer pipes into the facility, serving around 83,000 customers within the Tunasan catchment area.

The Tunasan WRF uses the Modified Ludzack–Ettinger (MLE) process—a modern biological treatment technology—to reduce pollutants before discharge. The facility complies with stricter effluent quality requirements under Department of Environment and Natural Resources (DENR) DAO 2016-08, as amended by DAO 2021-19, helping protect Laguna de Bay and the surrounding environment.

“Every wastewater facility we build is more than infrastructure—it is a commitment to public health, a step toward cleaner waterways, and an investment in a future where communities can thrive alongside a healthy environment,” said Maynilad President and CEO Ramoncito S. Fernandez. “By expanding sewerage coverage here in Muntinlupa and investing in modern treatment technologies, we help safeguard Laguna de Bay and strengthen responsible wastewater management in the West Zone.”

The project was implemented in coordination with the Metropolitan Waterworks and Sewerage System (MWSS), the DENR, the Laguna Lake Development Authority (LLDA), and the Muntinlupa City Government. Treated wastewater from the Tunasan WRF is discharged into Bubogan Creek.

With the addition of Tunasan WRF, Maynilad now has a total wastewater treatment capacity of 790 MLD, supporting the company’s broader program to accelerate sewerage and sanitation services in Metro Manila and contribute to the rehabilitation of Laguna de Bay.

Maynilad’s New Ceramic UF Modular Treatment Plant in Muntinlupa City Inaugurated

April 4, 2024March 25, 2024carlocarrasco

Recently in the City of Muntinlupa, water concessionaire Maynilad inaugurated their modular treatment plant which was designed to treat raw water using state-of-the-art ceramic ultrafiltration (UF) technology, according to the official announcement.

To put things in perspective, posted below is an excerpt from the company’s announcement online. Some parts in boldface…

Operated under a “build-operate-transfer” contract by Rendco-FFJJ Consortium, the Laguna Lake Modular Treatment Plant (ModTP) can produce 20 million liters per day (MLD) of potable water supply, augmenting the production of Maynilad’s three existing treatment facilities in Muntinlupa that also use Laguna Lake as a source.

The 20-MLD water supply from this additional facility will help to improve service reliability for Maynilad customers in the south, as its technologically advanced treatment processes ensure sustained production despite abrupt fluctuations in the lake’s raw water quality, which have been occurring with more frequency owing to climate change effects.

Besides the state-of-the-art Ceramic UF membranes, the facility also uses other key global treatment technologies, such as Ceramic Flatsheet Membranes, Nanobubble Technology, and Sludge Dewatering Press, all incorporated into a localized design that produces zero liquid discharge. This means that every drop of water is used and conserved.

The facility’s various treatment processes also require less maintenance and lower energy and chemical consumption, thus resulting in cost efficiencies and reduced environmental impact.

“Maynilad continues to adopt innovative solutions to meet the evolving water supply and treatment challenges, ensuring long-term resilience and sustainability. With this new facility, we are setting a milestone in municipal water treatment here in the Philippines, as we explore the potential of scaling similar technologies across other facilities,” said Maynilad President and CEO Ramoncito S. Fernandez.

The use of ModTPs that tap alternative sources to Angat Dam form part of Maynilad’s service enhancement program, which aims to address water security challenges.

Maynilad to increase water-storage capacity by constructing new reservoirs

January 9, 2024January 4, 2024carlocarrasco

For those who are relying on Maynilad for water, be aware that the water concessionaire will increase its water-storage capacity by a few hundred million liters (ML) by constructing new reservoirs but it will take a few years to be completed, according to the official announcement.

To put things in perspective, posted below is an excerpt from the company’s announcement online. Some parts in boldface…

West Zone concessionaire Maynilad Water Services, Inc. will add 211 million liters (ML) to its water-storage capacity by 2026 with its construction of four new reservoirs in different locations to improve supply availability and pressure for customers in elevated areas.

With this increased storage capacity, Maynilad will essentially have an additional 211 ML of potable water supply that is accessible at the distribution system level, ready for release during hours of peak demand.

“Households in elevated areas are typically affected by low water pressure whenever the demand goes up. Having more reservoirs will help to maintain supply availability despite strong water withdrawals from households in low-lying areas, so we’re building more of these storage facilities in strategic locations,” said Maynilad Chief Operating Officer Randolph T. Estrellado.

The four new reservoirs—to rise in Quezon City, Valenzuela and Muntinlupa—will entail an estimated investment cost of Php2.8 billion, which forms part of Maynilad’s Php220-billion service enhancement program for the period 2023 to 2027.

Maynilad currently has 37 operational reservoirs that can store 751 ML of treated water supply—up from only 10 reservoirs with 400 ML storage capacity after it rehabilitated 13 old reservoirs and constructed 14 new ones since 2007. With the construction of four new reservoirs until 2026, the company’s total combined water-storage capacity will reach 962 ML.

Let me end this piece by asking you readers: What is your reaction to this recent development? If you are a Maynilad customer, were you able to get a consistent supply of water over the past three months?

To put things in perspective, posted below is an excerpt from the news report of the Manila Bulletin. Some parts in boldface…

Muntinlupa Mayor Ruffy Biazon is hoping that Maynilad’s new water treatment plant in the city will solve water service interruptions that are being experienced by residents.

President Ferdinand “Bongbong” Marcos Jr. led the inauguration of Maynilad’s Poblacion Water Treatment Plant (WTP) in Muntinlupa on Dec. 15.

According to Maynilad, the Poblacion WTP has a capacity to produce 150 million liters of water per day.

Biazon said this December, the plant is expected to produce 50 million liters per day, and by the first half of 2024, it will go on full operations.

President Ferdinand “Bongbong” Marcos Jr. (PBBM) led today, December 15, 2023, the formal inauguration of Maynilad’s Poblacion Water Treatment Plant (WTP) in Muntinlupa City.

Maynilad said the new WTP cost P11 billion and it is the company’s third water treatment facility that gets raw water from the Laguna Lake.

It said the new plant will service about one million customers in Parañaque, Las Piñas, Muntinlupa, and Cavite.

“The additional water supply it produces will help to minimize service interruptions due to raw water quality shifts in Laguna Lake, which have been occurring with more frequency owing to the effects of climate change,” the company said in a press release.

It said the new treatment plant uses a multi-stage process of dissolved air flotation, cloth filter, biological aerated filter, ultrafiltration, reverse osmosis, and chlorination to ensure that the water from Laguna Lake passes the Philippine National Standards for Drinking Water (PNSDW) of the Department of Health.

Let me end this piece by asking you readers: What is your reaction to this recent development? If you are a resident of Muntinlupa City, are you optimistic that the new WTP of Maynilad will at least reduce the number of water service interruptions?

To put things in perspective, posted below is an excerpt from the Manila Bulletin report. Some parts in boldface…

The Muntinlupa City government will impose fines and penalties on Maynilad Water Services over a pipe repair project that damaged the National Road in Barangay Tunasan.

Muntinlupa Mayor Ruffy Biazon summoned representatives of Maynilad over their pipe repair project that has caused severe traffic.

Biazon said on Nov. 21, a pipe valve of Maynilad along the National Road in Barangay Tunasan got disconnected that led to water spilling out and causing cracks on the road. The crack got so big that one lane of the road had to be closed to traffic. This resulted in heavy traffic in the area. The City Engineering Office and Maynilad immediately responded to the incident.

Maynilad is repairing the pipe and road damage. The crack will be cemented to restore it that will allow the national road to be fully opened again to motorists.

According to Maynilad, Biazon said, the restoration will be finished by Nov. 25 and the national road will be fully opened again. But the City Engineering Office recommended additional days to totally cure the cement.

Let me end this piece by asking you readers: What do you think about this recent development? If you are a resident of Muntinlupa, were you stuck in heavy traffic along the National Road due to the reported damage? Do you think Maynilad has a lot to answer for in this case?

Over P1 billion allotted by Maynilad to upgrade water treatment plants in Muntinlupa City

October 25, 2023October 22, 2023carlocarrasco

Water concessionaire Maynilad announced recently that it has allotted over P1 billion for the upgrading of its Muntinlupa City water treatment plants, according to a news report by GMA Network.

To put things in perspective, posted below is an excerpt from the GMA Network news report. Some parts in boldface…

West Zone concessionaire Maynilad Water Services Inc. is spending a billion pesos to upgrade its water treatment plants in Muntinlupa City.

In a statement, Maynilad said it has earmarked P1.14 billion to further improve the treatment processes of its Putatan Water Treatment Plants (PWTP) 1 and 2 “in response to the worsening quality of the raw water from Laguna Lake.”

The company said the upgrades include the material and structural reinforcement of the facilities’ existing silt curtain, strengthening of the sludge management system, provision of activated carbon dosing at the intake, and replacement of all ultrafiltration membranes, among other enhancements.

The PWTP upgrades, which Maynilad said it has been implementing in phases, enabled the company to sustain normal water production since June 2023 despite sudden shifts in the water quality.

This led to improved service availability for Maynilad customers in the south versus the previous year, when the water production of PWTP 1 and 2 would immediately drop following spikes in total dissolved solids, algae proliferation, and the presence of organic and inorganic matter in the lake water, the company said.

“We have had to incorporate additional treatment processes at Putatan WTP to handle some quality parameters of Laguna Lake that now occur at levels not seen from recorded prior ten-year experience. This investment is essential so we can continue to maximize the lake’s strategic value as a water source for Metro Manila,” said Maynilad chief operating officer Randolph Estrellado.

Estrellado added that the PWTP improvements being done were aligned with the recommendations of the Public Utility Board (PUB), the national water agency of Singapore, which was invited to the country by MWSS Administrator Leonor Cleofas to assess the said facilities and share their expertise with Maynilad.

Maynilad said its PWTP 1 and 2—the largest membrane-based water treatment plants in the Philippines—are the first to utilize Laguna Lake as an alternate source to Angat Dam.

The company added that it is currently constructing another 150-million-liter per-day treatment plant in Poblacion, Muntinlupa City, which will be its third facility to tap Laguna Lake as a source.

Let me end this piece by asking you readers: What is your reaction to this recent development? If you are a resident of Muntinlupa City, how was the quality of service you have been getting from Maynilad over the past six months? Is the water supply from Maynilad constantly available for your needs?
