0

ILOILO CITY: The Department of Environment and Natural Resources has created a comprehensive work plan for the rehabilitation of the Iloilo River system and its creek tributaries like Dungon and Calajunan creeks.

The work plan will become the basis for the improvement of the river’s water quality and its tributaries in terms of dissolved oxygen, biochemical oxygen demand and coliform concentrations.

In his report to the Iloilo-Batiano River Development Council (IBRDC) last March 31, Raul Lorilla of the provincial environment and natural resources office said the department is implementing Oplan SWIM or the Sustainable Work plan for Iloilo River Management.

The Iloilo River is approximately 12 kilometers from the Parola area to its upper reach in Barangay Sooc, Arevalo in Iloilo City. Its pollution problem comes from domestic wastes, oil slicks from ocean-going vessels, public markets and commercial establishments along the river.


The three-year average water quality showed that the river contains 4.008 of dissolved oxygen, biochemical oxygen demand of 4.47, total coliform of 48,849.43 MPN/100 ml and fecal coliform rate of 27,32.77. Calajunan Creek has total coliform level of 767,881.43 and fecal coliform rate of 393,461.48 while Dungon Creek has a total coliform level of 2,877,617.46 and a fecal coliform rate of 1,363,293.68.

Lorilla reported that short-term plans that will be implemented in one to six months include the installation of garbage booms, and the acquisition of trash collection boats and vacuum trucks.
