THE Metropolitan Waterworks and Sewerage System - Regulatory Office said that they will investigate the water service being distributed by Maynilad, which cannot be used for drinking.

It will be recalled that Maynilad had advised their customers in Bacoor, Imus, Las Piñas, Muntinlupa, and Parañaque to not use the water being distributed to them for water or for cooking.

"Maynilad is supposed to provide potable water 24/7 to its customers. This is not potable water. We want to understand the situation and investigate why they are not able to provide this potable water," according to Atty. Patrick Ty, chief of the MWSS-RO.

"We all know this is seasonal, this happens every year, so they should have been ready for this," he added.

Earlier, Maynilad Corporate Communications Head Jen Rufo, said as to why this happened.

"Mula sa matagal na mainit na panahon na tagtuyo, nag-shift na siya towards the rainy season. And with that change in the season, may certain variations doon sa mga water quality sa Laguna Lake. Iyong pagbabago niya ay medyo significant so lumagpas iyong parameters doon sa treatment capability ng treatment plant sa South…nabawasan iyong produksyon para mapanatili iyong drinking water qualities ng water. But if we keep doing that, strict compliance, sobrang kaunti iyong nailalabas ng planta na supply, kaya humahaba iyong service interruptions…nagpaalam tayo sa ating regulators na kung papayag sila na ilalabas namin ng slight, i-relax namin ng kaunti iyong parameters doon sa water quality na ilalabas sa ating treatment plants. Kasi by doing that, ma-i-increase natin iyong water production at mas kaunti iyong makakaranas ng service interruptions," she said.
