New water basin plan okay-A A +A
Wednesday, July 16, 2014
RAINWATER accumulated from a harvesting facility has to be treated before it can used for human consumption, an official of the Baguio Water District (BWD) said.
Although it is possible to have a residential rainwater harvesting facility, BWD OIC division manager Fernando Peria said the public has to be cautious.
Peria added just because it is rainwater, it does not mean it is safe.
"Ang tubig ulan ay pwede ring contaminated sa taas palang depende sa extent ng air pollution sa taas (atmosphere)," he stressed.
He recommended rainwater must be used only for domestic purposes such as cleaning, laundry, bathing and watering of plants among others.
However, for potable use or for drinking, he said, "In my opinion it is not really advisable unless it will undergo a sophisticated treatment process.”
A treatment process such as "reverse osmosis" will require application of chemicals to help treat residue in the surface water.
Peria is looking forward to a possible construction of another rainwater harvesting facility in Baguio City.
Mayor Mauricio Domogan earlier said a rainwater harvesting facility was included in the list of priority projects for 2014, which he submitted to the Department of Budget and Management.
The city mayor hopes a rainwater harvesting facility will help address water shortage as it will provide concessionaires an alternative.
Peria said that a rainwater harvesting facility will require a spacious land so the City Government must carefully locate an ideal area.
Currently, the rain basin in Mount Sto. Tomas is the only rain harvesting facility being utilized by the city.
Peria said the rain basin is now accumulating water since the onset of rainy season. He said the accumulated water will only be distributed after a long process of treatment.
