Hedcor, the largest developer of run-of-river hydropower plants, prevented 412 tons (373, 332 kilograms) of trash flowing into Talomo River in the whole year of 2011 to first quarter of 2012 through a trash rack (composed of a steel grate with narrow gaps) installed as one of the components of a hydropower plant.
Eight trash racks are installed within the facilities of the five run-of-river Talomo Hydropower Plants to prevent trash and debris entering the hydropower system. The turbines are designed solely for water to run. Any trash that enters to the machine can hamper it and might cause the power generation to stop.
“Preventing garbage to get into our run-of-river hydropower facilities will secure the whole process of operations”, Hedcor Vice President for Mindanao Operations Engr. Rolando Pacquiao said. “Aside from securing our facilities, abiding strictly to RA 9275 and DAO 2005-10 or Clean Water Act is also our top concern”, Pacquiao added.
The RA 9275 or the Philippine Clean Water Act of 2004 provides a clear policy on water pollution control. Hedcor contracted garbage hauler to regularly ensure the proper segregation or disposal of the hauled trash to the sanitary landfill and even recycled some, as one way of administering quality water management.
“After we use the diverted water to run our turbines in Talomo plants, the water will then be returned to river in a cleaner state, zero waste,” Pacquaio said.
The Talomo River runs the 5 mini-hydropower plants of Hedcor with a total capacity of 4.47 megawatts. These are the first and oldest plants operated and managed by Hedcor since 1978.
Apart from the operations’ effort in preventing trash going into the river, Hedcor conducts a regular Eco-market day in its host communities. The Eco-market day serves as a venue for the residents to properly segregate waste and sell it to Hedcor. Hedcor then delivers it to the contracted buy back centers in the city.
Hedcor is a wholly-owned subsidiary of AboitizPower – the holding company for the Aboitiz Group’s investments in power generation, distribution, retail and power services. It is a major producer of Cleanergy, its brand for clean and renewable energy in the Philippines with several hydroelectric and geothermal assets in its generation portfolio and also has non-renewable power plants located across the country. The company owns distribution utilities that operate in high-growth areas in Luzon, Visayas and Mindanao.
