Maynilad upgrades La Mesa Treatment Plant sedimentation basins
July 08, 2018
West Zone concessionaire Maynilad Water Services, Inc. (Maynilad) recently completed the upgrade of a sedimentation basin at La Mesa Treatment Plant (LMTP) 1 in Quezon City. This is part of the company’s overall PhP7-billion rehabilitation project for LMTP 1 and 2, which produce about 2,400 million liters of water per day for some nine million customers.
The 12 sedimentation basins at LMTP 1 are being fitted with tube settlers and sludge scrapers, increasing the plant’s capacity to address high turbidity in the raw water during the rainy season. “While there are 11 more basins to go, this is a significant milestone in the rehab project of La Mesa and our ability to respond to the challenges of climate change,” said Maynilad Chief Operating Officer Randolph T. Estrellado.
The rehabilitation of the 12 basins is being done in phases so that plant operations will not be disturbed even as the upgrades are being done. “We are upgrading one basin at a time, because we cannot shut down the plant and interrupt water service to give way to the rehabilitation work,” Estrellado added.
Aside from rehabilitating the sedimentation basins to improve treatment capacity, other upgrades being done at LMTP 1 and 2 are the retrofitting of structures for enhanced earthquake resiliency, and the automation of processes for more reliable operations. The rehab project is targeted for completion in 2020.
