More challenges are expected ahead of the ongoing pipe laying and excavation works of the Davao City Bulk Water Supply Project of Apo Agua Infrastructura, Inc. (Apo Agua) and Davao City Water District (DCWD). 

In a project update, Apo Agua said that from October 2019 to January 2021, excavation and foundation works for its Water Treatment Plant in Barangay Gumalang which started this month is expected to face the challenges of road right of way and traffic.

DESANDER. Excavations are now completed and concrete works have started.

“We will be working at multiple sites spanning 15 barangays which is estimated to begin this month, October 2019 up to January 2021,” Apo Agua general manager Ones Almario said. “This will be done in segments within the barangays so that work will be efficient and to effect as little inconvenience as possible on the part of pedestrians and motorists,” he added.

The 60-kilometer treated water pipeline will start from the water treatment facility in Barangay Gumalang and end in DCWD’s five existing water systems namely, Dumoy, Calinan, Tugbok, Panacan, and Cabantian, as well as three additional new water systems at Talandang, Mandug, and Indangan. 

WATER TREATMENT PLANT. Earthworks for laying and compaction are ongoing for Flocculation and Settling Tanks at the Water Treatment Plant site. 

A project site tour was conducted on October 7 which was attended by Councilor Danilo Dayanghirang, chair of the city council’s committee on finance, ways, means and appropriations.  
Given the scope of the works, Dayanghirang said the people should support Apo Agua and DCWD through their understanding of the consequences it would bring particularly on the road right of way and traffic. 
“The Apo Agua and Water District deserve to be assisted in terms of moral support, in terms of understanding especially on some challenges on the road right of way, and of course traffic, ” Dayanghirang said. 

To ensure an uninterrupted and smooth flow of construction works, the project proponents have coordinated with directly concerned government agencies. 

“We are coordinating with the 15 barangay councils, City Engineer’s Office, City Transport and Traffic Management Office, Department of Public Works and Highways Davao Region, and the Public Safety and Security Command Center, to ensure that traffic, security, and rescue protocols are in place,” Almario said. 
“We will also disseminate the pipe-laying schedule through our website and social media accounts so that the Davaoeños can plan their route ahead. We ask our fellow Davaoeños to bear with us through the inconveniences such as traffic, which may ensue as a result of these pipe-laying activities in the second and third districts of Davao City.”
He asked for people’s understanding and cooperation. ”All of these works are for the Davao City Bulk Water Supply Project of DCWD which will benefit more than a million Davaoeños by the first half of 2021,” he said.

Also, the Apo Agua’s pipe-laying schedule will be available on its website at www.apoagua.com and on its Facebook page, Twitter and Instagram accounts through @apoaguainfra.

Last September 25, J.V. Angeles Construction Corporation (JVACC), the project’s engineering, procurement, and construction contractor, clocked in 1,000,000 safe man-hours without any lost-time incident. The company finds this significant in the history of the project.  
The project  now employs close to 500 laborers and skilled workers who are mostly from its host barangays Gumalang, Wines, Tawantawan, Tambobong, and Tamugan.
As part of the construction works, the Tamugan River is being diverted. 

WEIR. The river flow is diverted to a temporary channel (in photo) to allow for the construction of the weir along the Tamugan River, the project’s water source.

DCWD, Apo Agua, and JVACC conducted a river diversion activity last October 5 at Barangay Tawantawan. 

Almario said the diversion of the river water to a  temporary channel is necessary to allow for the construction of the weir which is located along Tamugan River, the project’s water source. A weir he said, is different from the traditional dams as it allows the water to flow through without obstruction and only diverts a portion of the water towards the project’s pipeline. 
Apo Agua Infrastructura Inc. said the P12-billion water project is targeted to start operations by  first half of 2021.
Touted as the largest bulk water supply facility in the country, the water facility stands to provide more than 300 million liters of safe water per day to DCWD.
