Effective Waste Water Management

Cesspools pose a huge threat to human and environmental health when the waste flows into our waters and are damaging to our coastal ecosystem. Due to recent legislation (Act 125) all of Hawai'i's 80,000 cesspools are required to be converted to an efficient waste water management system by the year of 2050. All of the cesspools are assigned a "priority" based on how big of a risk they pose to water sources and about half of Hawai'is cesspools pose a threat to our water, A few quick facts about the importance of making cesspools a thing of the past here in Hawai'i:

- everyday, 53 million gallons of raw sewage is discharged into Hawai'i's waters from the state's cesspools. 

- 43,000 of the state's cesspools pose a threat to Hawaii's water. 

- Cesspools can contaminate ground water, drinking water, streams, and oceans with disease-causing pathogens.
