Let’s talk STORMWATER!

When rainwater hits impervious surfaces like roads, rooftops, and driveways it becomes stormwater runoff. Stormwater runoff picks up potentially detrimental and hazardous material like trash & debris, nutrients, sediment, metals, oxygen demanding substances, oils & grease, and bacteria/pathogens. These pollutants have many sources and varying negative effects on the environment.

The City and County of Honolulu is leading the way in developing, designing, and implementing reliable and sustainable treatment systems to fight stormwater pollutant discharges by using various devices. 

Just recently, the City and County of Honolulu’s Department of Facility Maintenance Storm Water Quality Division installed a Debris Separating Baffle Box Separator (DSBB) in Niu Valley to help mitigate stormwater runoff in the Maunalua region. Baffle boxes are proven to be effective in removing sediment, suspended particles, and associated pollutants from stormwater, along with trash and debris.

With sediment loads being a primary source of concern for Maunalua Bay, we hope this makes a difference!
