MANILA, Philippines — Plano ng West Zone concessionaire Maynilad Water Services Inc. (Maynilad) na gamitin ang ‘treated used water’ para gawing malinis na inuming tubig gaya ng ginagawa sa Singapore, South Africa, Namibia, at Estados Unidos.
“Water is a scarce resource. Given the growing population’s increasing demand for water plus the strain on existing sources due to climate change, we should consider using previously untapped sources—including used water—to augment supply. There are now reliable and effective treatment technologies that make it a viable option,” pahayag ni Maynilad President and CEO Ramoncito S. Fernandez.
Gagamitin dito ng Maynilad ang bagong Modular Treatment Plants (ModTP) para makakuha ng malinis na inuming tubig sa halip na pagkunan ng tubig ang mga ilog .
“The treated used water discharged by STPs is actually a more reliable water source than raw river water because it is climate independent; the quality is controlled and less variable,” pahayag naman ni Maynilad Quality, Sustainability and Resiliency head Roel S. Espiritu.
“If we use the river directly as source, trash and other pollutants thrown into it by surrounding communities could drastically change the river water’s quality. This could affect the volume output of a ModTP, which has to adjust its treatment parameters with sudden shifts in the raw water quality.” dagdag pa ni Espiritu.
Mula 2010 hanggang ngayon ang Maynilad ay naglilinis ng raw water mula sa Laguna Lake gamit ang sewage treatment method para sa initial purification ng tubig ng lawa bago ito idaan sa ibat ibang treatment processes para maging malinis na inuming tubig. Dahil sa paggamit ng Laguna Lake nababawasan ang pagkuha ng tubig sa Angat dam bilang pang suplay ng tubig sa Metro Manila.
