Waterworks Gardens is a public park next to King County's South Treatment Plant in Renton, Washington.

This is a place where art, technology and nature join in a unique way. Along with trails, public art, native plants and wildlife, the ponds and marshes of Waterworks Gardens filter and clean stormwater from the treatment plant's 50 acres of roads, parking lots and hard surfaces.

After passing through Waterworks Gardens, the treated stormwater flows into Springbrook Creek.

Waterworks Gardens is designed as a series of garden "rooms." The Knoll is the entry to Waterworks. The path then passes through a series of leaf-shaped ponds, an inlaid mosaic Grotto and wetlands. Waterworks Gardens opened in 1996.

The gardens are open between dawn and dusk year-round.

Parks and trails

The City of Renton's Springbrook Nature Trail and the Black River Riparian Forest provide opportunities to explore nature in an urban environment.
