Mayor Rodrigo Duterte went into discussion on watershed protection in his television program on Sunday particularly on protecting the city’s watershed areas.
But there was no feeling of deep concern over the issue even as it is reported that there is agri-business aggression into the watershed areas.
Of course Duterte is confident about preserving, conserving and protecting the watershed areas such having been ensured by the Watershed Conservation, Protection and Management Ordinance. The landmark measure was authored by then City Councilor Arnolfo Cabling and approved by the Davao City Council in 2007.
The Dabawenyos’ greatest gift from God is their water resources in the underground reservoir of Dumoy, which is replenished by recharge points in the watershed areas in upland areas of the Third District.
Protecting, conserving and managing the Dumoy water resources practically require the same routine in treating the watershed areas to keep them safe and healthy and reliable as water sources. You do good to the watershed areas and you do good to the water resources. Unhealthy watershed areas eventually convert to a dried up Dumoy underground reservoir and rivers and into thirsty Dabawenyos if there is no alternative water sources.
Davao City may be blessed with its water sources, but there is no guarantee this God-given gift could last forever.
Studies show that the city’s underground reservoir located mostly in the Dumoy area may be depleted in 50 years if no alternative source is identified to ease pressure on this source where the Davao City Water District pumps out water for domestic use of the Dabawenyos.
With the city’s population growing at a fast pace, demands could double in 50 years—a scenario that should make imperative identification of alternative sources.
The first is a long term route that may not be as reliable given the volume of the demand of the city’s fast rising population growth. Water tapped from underground water reserves (as in DCWD pumping out water from the Dumoy underground reservoir — need hundreds of years to be replenished by recharge points in the watershed areas. The surface water project is the short-term immediate cure with water simply diverted to DCWD pipelines to be delivered by gravity from upland Marilog to the downtown lowland consumers.
This is a fact facing DCWD which should not be taken lightly.
Several studies conducted on the city aquifer’s longevity makes urgent DCWD’s Tamugan River surface water development project.
A study by the National Water Resources Board (NWRB) indicated that with the daily rate of extraction from the underground reservoir, there would later be severe depletion of the underground water reservoir.
DCWD is hell-bent about building the Tamugan River Surface Water Project at the soonest, because the project is the only hope for DCWD to meet its commitments to the Dabawenyos.
The Tamugan project when in full operation could provide the same volume of water that it presently draws out of Dumoy.
This would mean that the Dumoy aquifer would be saved from depletion and allowed to replenish its stock while Tamugan comes in as an alternative source.
But conserving the city’s water sources should not be the be-all if we want to ensure supply of water for the future generation.
Managing, preserving and conserving our forests and the watershed areas is the first step to ensure the supply. After all, the life of Tamugan River like the Dumoy aquifer depends on how healthy are our watershed areas.
Davao City should be thankful for the Watershed Protection, Conservation and Management Ordinance which has set into place the mechanics for the protection of our watershed areas.
As Duterte said in his television program, we have the tool in the watershed ordinance to protect, manage and conserve our watershed areas.
This ordinance should be implemented to the fullest now if we don’t want to see thirsty Dabawenyos in future unable to find water due to our wanton disregard for the environment and our forest and our watershed areas, and our our water resources.
