Xavier conserves water

picture-037.jpg
Last year, Xavier School installed a wastewater recycling plant that is expected to provide at least 60% of its current raw water consumption. The system collects water from drainages, drainpipes, and toilets, and through a membrane-based process, treats the water for reuse for irrigation of the football fields, general cleaning, and toilet flushing.
While the recycled water is certified for standards based on the US Environmental Protection Agency 2004 policy, this would only be recycled back for use on non-human contact purposes. All the water used for these functions comprise around 60% of Xavier’s total water bill.
This investment in water recycling is part of the school’s ongoing program to become more responsible in the use of resources, as well as a continuing effort to reduce costs without sacrificing the welfare and best interests of the community. The school partnered with Technotest Inc. (www.technotestinc.com) to commission this process and system which involves the use of both chemical and membrane-technology that is similar to what Singapore uses to treat their wastewater for reuse and recycling.
11052009001.jpgCompleted and running since November 2009, the system required extensive replacement of pipes and the construction of the treatment system. The capital investment, based on the projected savings in the monthly water bill, should be recovered in 3.5 years. More than the cost benefits, the system serves to underscore the school’s commitment to conservation as a sound environmental philosophy. With this move, Xavier School becomes the first academic institution in the Philippines to have its own waste-water recycling system.
Consider these facts:
A DENR study released in 2007 indicated that the Philippines would likely face a severe crisis in fresh water supply by the year 2010.
The study further showed that the Philippines ranked second to the lowest among Southeast Asian countries in fresh water availability.
The supply problem would be particularly critical in Metro Manila, where the rampant extraction of ground water has resulted in the lowering of the water table and a consequent increase in water salinity. (Xavier School has shut down its deep well since 2002 precisely due to this problem.)
In light of increasingly severe climate changes such as the El Nino phenomenon, and the deepening water crisis that future generations of Filipinos are likely to face, Xavier School hopes the entire Xavier community will join in and embrace conservation to preserve the rapidly dwindling lifegiving resource of clean fresh water.
