The City and County of Honolulu’s Department of Environmental Services (ENV) is dedicated to keeping O‘ahu clean, healthy, and sustainable—today and for future generations. From the moment you turn on a faucet or set out your refuse cart, ENV is hard at work behind the scenes, safely managing what our community no longer needs.
Every day, ENV collects and treats approximately 96 million gallons of wastewater, ensuring it’s handled responsibly before returning clean water to the environment. Our crews also collect household trash and green waste from neighborhoods island-wide, operating six days a week to help keep our communities beautiful and sanitary.
But ENV’s mission goes beyond just providing essential services. We believe protecting O‘ahu’s environment is a shared responsibility. By partnering with residents, local businesses, and government agencies, we foster a sense of stewardship and joint action to care for our island home—so our keiki can enjoy a vibrant and thriving environment for years to come.
If you have questions or need assistance navigating our website, please reach out to the ENV Public Information Officer at env@honolulu.gov. Together, we’re working for a cleaner, safer O‘ahu.
