Summary

Come celebrate with students, parents and staff in partnership with the RainWise program the new rain garden and cisterns installation at Highland Park Elementary School on Saturday, Oct. 5, from 11 a.m. to 1 p.m. The new installation will collect nearly 50,000 gallons of rain from the school’s roof, helping to maintain capacity in the combined sewer-stormwater system and providing a summertime irrigation source.

Story

See the latest piece of green stormwater infrastructure in King County on Saturday, Oct. 5, when students, parents and staff of Highland Park Elementary School in Seattle gather to celebrate the installation of new cisterns and a rain garden, in partnership with the RainWise environmental program.

The Oct. 5 celebration is scheduled from 11 a.m. to 1 p.m. at the school, 1012 SW Trenton St., Seattle. Participants can learn how rain gardens and cisterns help protection water quality, and homeowners can get information about their eligibility to apply for rebates for installing install cisterns or rain gardens at home.

Highland Park’s new cisterns and rain garden will capture 47,400 gallons of stormwater a year from the school’s roof – the equivalent of nearly 600 bathtubs worth of water.

Rather than flowing into the combined sewer-stormwater system where it decreases the overall system’s capacity during wet weather, stormwater collected by this green infrastructure can be used for irrigation and help recharge groundwater.

The RainWise program installed this green infrastructure installation to promote equity and inclusiveness. Highland Park Elementary serves a diverse population of underserved children, with nearly 80 percent of students qualifying for the free and reduced-price lunch program.

RainWise is a rebate program that helps eligible property owners manage stormwater by installing rain gardens and/or cisterns on private property. This prevents flooding, adds attractive landscaping, and can provide water for summer irrigation. The rebates can cover most or all of the cost of installing cisterns and rain gardens on your property. To receive a rebate, you must live in an eligible CSO basin.

RainWise is a joint program of King County’s Wastewater Treatment Division and Seattle Public Utilities. To receive a rebate, you must live in an eligible combined sewer overflow basin. The average rebate has been around $4,400. See if your property is eligible, find a contractor, and apply at RainWise Rebates.

The RainWise program has helped with installations on over 54 acres of rooftops that channel rainfall to rain gardens and cisterns. These properties are keeping almost 30 million gallons of runoff annually out of the combined stormwater-sewer system and controlling overflows in local water bodies during heavy rains.
