The Davao City Water District (DCWD) has called on residents to observe proper septage management, stressing its vital role in protecting public health and preserving the city’s water resources.
According to DCWD, improper handling and disposal of septic waste can result in groundwater contamination and pollution of rivers and coastal waters, posing serious risks to communities.
The water utility company cited a 2023 report by the Department of Environment and Natural Resources (DENR) linked pollution along major waterways to “wastes from commercial and agricultural areas, and sewage waste from heavily built-up areas,” particularly in downstream portions of the river system.
In a recent advisory, DCWD warned that exposure to contaminated water — whether through swimming, bathing, or drinking — can lead to serious waterborne diseases such as gastroenteritis, cholera, diarrhea, hepatitis A, typhoid, dysentery, and polio.
“One of the major pollutants identified is fecal coliform, a type of bacteria found in the digestive tracts of warm-blooded animals. Its presence in water indicates fecal contamination and the potential spread of harmful pathogens. Leaking or overflowing septic tanks are among the primary sources of this pollution,” DCWD stated.
Meanwhile, the city government of Davao has partnered with DCWD to implement a comprehensive Septage Management Program (SMP).
The initiative establishes a systematic process for the safe desludging, transport, and treatment of septic waste, ensuring it does not contaminate the environment.
The SMP aims to improve water quality, sanitation, and overall public health, while preventing the spread of waterborne illnesses and fostering cleaner, healthier communities.
DCWD also reminded residents to comply with local ordinances requiring the professional desludging of septic tanks at least once every five years.
“This simple but crucial step helps prevent contamination, protect families from diseases, and restore the vitality of our local waterways,” the agency said.
