ERS machine eyed to reinforce old sewer treatment plant

BAGUIO CITY – Banking on the headway gained in its solid waste management program, the city government shifts its focus on the city’s liquid wastes by reinforcing the operation of the moribund sewer treatment plant (STP) with another Environmental Recycling System (ERS) unit.

Mayor Mauricio Domogan Wednesday told his media briefing that an allocation for the purchase of a smaller ERS machine to be stationed at the STP at Sanitary Camp barangay has been included in the 2011 city budget which was approved by the city council last Monday.

The city recently purchased two units of P24-tonner ERS machines worth P64 million each to tackle its biodegradable wastes.  The machines began full operations last Monday.

The mayor said smaller ERS machine will boost the operation of the 25-year old STP to enable the city to treat its liquid wastes more effectively and more rapidly.

He said the ERS machine could purify sewage water that flows down to the Balili River and thus would help minimize pollution of the river.

City environment and parks management office head Cordelia Lacsamana said the STP which was built in 1986 has now been “operating 40 percent beyond its rated capacity.”

She said the plant was designed with an 8,600-cubic meter capacity but the city’s liquid waste output has since risen by 40 percent.

She said the ERS machine would facilitate the processing of sludge called “de-sludging” in less time than the present set-up which takes time due to the natural drying process required.

“With the ERS machine, there would be no need for the drying process and the city can conduct the de-sludging process anytime,” Lacsamana said.
Lacsamana said they intend to facilitate procurement of the two-tonner machine which would cost P24 million immediately to boost the operation of the STP.
