Water Pollution Prevention at `Aikahi Elementary School

‘Aikahi Elementary School is located on Ilihau Street near Kaneohe Bay Drive in Kailua. Storm water discharges from the campus flow via the small Municipal Separate Storm Sewer System (MS4) directly to an unnamed drainage channel, and to the City MS4, which also discharges to the unnamed drainage channel, a Class 2 inland water. The unnamed drainage channel empties in Nu’upia Pond. The average annual rainfall at the school is approximately 31 inches. The school site is fairly flat and surrounded by Ilihau Street, residential lots, and ‘Aikahi Park subdivision, with the unnamed drainage channel running along its northeast boundary. The issues of importance for storm water quality on our campus include potential storm water pollution from erosion, dumpster overflow, and illegal dumping.

What our STAFF & PARENTS Can Do To Help Protect Water

Use water wisely. By conserving water, the amount of wastewater needing treatment and disposal will be reduced. Over-watering and runoff can carry pollutants into the storm drain system.

Use and dispose hazardous substances properly. Always read the product label and choose the least toxic alternative. Motor oil, paints, solvents and other chemicals should not be poured on the ground or down the storm drains, because they can pollute our streams and ocean. Motor oil is recycled at oil change locations; other chemical products should be first used up by buying only the amount needed; typically unused excess could be evaporated or soaked into clay litter, wrapped in plastic and disposed with trash. Excess pesticides require special handling and must be disposed as hazardous waste.

Use fertilizer and pesticides sparingly. Choose the least toxic alternative such as compost for fertilizer, repellant/resistant plants and instead of bug sprays, use baited traps. Follow label instructions and use only the amount needed. Apply outdoors only during dry weather, rain water can easily carry substances to nearby storm drains and stream.

Landscape the land to prevent erosion. Cover bare ground with grass, shrubs or trees to hold soil in place. Establish native plantings and provide vegetation buffer zones along storm drains and stream.

Improve housekeeping. Fix water leaks throughout campus by replacing faucet washers and toilet flappers as needed. A slow drip or leak can easily waste more than 100 gallons of water a week. Put all litter into trash cans so it does not get washed into the storm drains or streams.

Implement annual campus cleanup event. Coordinate cleanup event for the whole campus to collect litter and address any other issues that would impact storm water quality, such as storage of materials and soil erosion areas. Maintain record of litter collected and other changes that impact storm water quality and take before and after photos of campus.

What STUDENTS Can Do To Help Protect Water

Study storm water management. Teachers can address hazards associated with illicit discharges to our storm drains and streams. Develop steps that can be taken to reduce storm water pollution.

Learn about good housekeeping. Good housekeeping practices are simply maintaining a safe, orderly and clean learning environment. Conduct an individual or class project to reinforce pollution prevention activities consistent with protecting storm water.

Learn where your wastewater goes. Investigate the wastewater drainage process from campus to the ocean via streams, storm and sewer drains.

Educate others. Conduct an individual or class project to inform others about protecting
our ocean from pollution.

Participate in annual campus cleanup event. Participate in a campus cleanup day to collect litter and address any other issues that would impact storm water quality, such as storage of materials and soil erosion areas.

Report illegal discharge. You can make a difference in our school and community.
