“In 2021, JICA submitted to the city the results of the data collection survey on current systems—or the lack of it—to get a scope of the extent of what needs to be done,” he said.
Cortez said that the local government’s Infrastructure Modernization for Davao City (IM4 Davao) study in June 2018 was “just an initial investigation of what is not present, what is lacking in wastewater management systems and a general identification of systems that must be pursued within the timeframe of the plan” between 2018 and 2045.
Mayor Sebastian Duterte signed the agreement with JICA Chief Representative Sakamoto Takema at the Arcadia Activity Center in Davao, attended by Japanese Consul General Ishikawa Yoshihisa, delegates from JICA, executives from the Davao City Water District, and other city officials.
In a press release issued by the City Information Office, the master plan study, set to commence within this year, will be conducted by a third-party firm chosen by JICA, and will have a three-year timeline consisting of “wastewater management planning, feasibility study for priority projects, and capacity development, among others.”
Duterte acknowledged the need for a “sustainable wastewater management system in the city” as he vowed to support the conduct of the study to ensure “adequate water supply to the city’s growing population while mitigating pollution in the surrounding waters.”
He said that a comprehensive wastewater management has a beneficial impact to the local community, and that efforts must be taken to establish “an effective network to execute the vital steps of data collection, evaluation, and analysis of the current situation.”

Takema said that clean water is “very crucial to economy” because it supports sustainable food production, exports, and tourism.
He assured that JICA would assist in the crafting of the best approach to wastewater management.
