Only Rain in the Drains

This initiative helps protect the island's delicate ecosystems by raising awareness about the impact of pollutants carried by storm water. By educating the community, we can help ensure cleaner streams, rivers, and oceans for future generations.

Secondly, storm water drain outreach plays a vital role in preserving water quality, which is crucial for Oahu's drinking water, marine life, and coral reefs. By preventing contamination, we can help safeguard the health and sustainability of our valuable water resources.

The Navy has long been dedicated to protecting the environment, and by promoting storm water drain outreach, NAVFAC Hawaii continues to improve and demonstrate their commitment to responsible practices and sustainability.


Program Overview

Under the Clean Water Act (CWA), the United States Environmental Protection Agency (EPA) and the State of Hawaii Department of Health (HDOH) establish environmental programs to protect the Nation’s waters. The National Pollutant Discharge Elimination System (NPDES) program was created through the CWA and is implemented through each State. The NPDES program requires all discharges into the waters of the United States to be permitted and comply with receiving water quality standards to protect, maintain, and improve the water quality of our oceans. To capture all discharges from the Navy (except from Shipyard areas which are under a separate NPDES permit), Navy Region Hawaii operates under a comprehensive NPDES Permit for Joint Base Pearl Harbor-Hickam (JBPHH). This Storm Water permit was issued to the Navy Region Hawaii by the HDOH.

The permit applies to Navy Region Hawaii properties including, but not limited to: Pearl Harbor-Hickam main base, Lualualei Annex, Fleet Logistics Center – Pearl Harbor, Naval Facilities Engineering Command Hawaii NAVFAC Hawaii, Naval Inactive Ships Maintenance Facility, and Naval Computer and Telecommunications Area Master Station Pacific at the Wahiawa Annex. Although the permit doesn’t include all Navy areas, such as the Pacific Missile Range Facility at Barking Sands, Kauai, procedures are followed to prevent water pollution.

The Storm Water Management Program consists of the following programs:

  • Public Education and Outreach
  • Public Involvement and Participation
  • Illicit Discharge Detection and Elimination Program
  • Construction Site Management Program
  • Post-Construction Storm Water Management Program
  • System Maintenance and Pollution Prevention


Why are we concerned about storm water?

Storm water runoff occurs when water from rainfall flows over the ground, through the storm drain system, and into a water body such as a stream, river, wetland or ocean. Storm water can accumulate debris, chemicals, dirt, and other pollutants and transport them into a storm drain system or directly to a water body. Anything that enters a storm drain system can be discharged untreated into the water bodies we use for recreational activities including swimming, surfing, and fishing.

How do we minimize storm water pollution?

The key to storm water pollution prevention is to prevent pollutants from coming into contact with storm water and remove pollutants from storm water when full prevention is not possible using Best Management Practices (BMPs). BMPs can be structural and procedural systems.
