Ecoyards offers complete outdoor drainage solutions to help you deal with these problems. We can help you find the right drainage tool to divert excess water away from your home, including catch basins, trench drains, French drains, cisterns, rain gardens, and proper downspout drainpipe connections.

Company owner Andy Nicholls holds a bachelor’s of science degree in hydrogeology, or the study of groundwater, and is a licensed geologist in Washington (License #2559). Andy has expertise in groundwater flow patterns and the drainage characteristics of soil types found in the Seattle area. Drawing on his knowledge of the area, he can determine the most cost-effective and permanent solution for each drainage problem. Ecoyards also is a licensed landscape contractor with the city of Seattle’s Rainwise Program, a program to encourage homeowners to improve natural drainage. The company has experience in building and maintaining rain gardens, which allow you to redirect rain from your roof into a shallow depression that filters, holds and absorbs water.

Our outdoor drainage systems typically include the following components:

Catch basins and trench drains

When designing a proper drainage system, it is helpful to consider the topography of the area, drainage characteristics of the underlying soils, and potential issues from poor surface water drainage. Low-lying and poor-draining spots can benefit from the installation of catch basins and/or trench drains. A catch basin is installed underground and helps take out debris like leaves, garbage, and mud from a drainage system. A trench drain, sometimes called a channel drain, is typically a long, narrow floor-type drain. Both catch basins and trench drains are available with surface grates that can easily handle heavy foot traffic. Decorative grates can be used to enhance the beauty of their surroundings in driveways, courtyards, patios, and other professionally landscaped areas.

French Drains

French drains are typically used to draw excess groundwater and surface water away from an area of concern. French drains consist of a perforated drainpipe covered with clean drain rock. These drains are installed below ground, and the drain rock is covered with filter fabric to prevent the back-filled soil from clogging the drain rock and drainpipe.

Downspout connections and rain gardens

Proper management of stormwater runoff from rooftops is an essential part of an effective drainage system. On flatter, well-draining properties, downspouts can sometimes be connected to rain gardens. By holding and infiltrating rainwater, rain gardens help protect our waterways and reduce flooding. These gardens can be shaped and sized to fit your yard. They also can be attractive landscape features, filled with native plants or other shrubs, trees and plantings that fit your soil, sun conditions and surroundings.  To learn more about rain gardens and the city of Seattle’s Rainwise Rebate program, please visit our service page on rain gardens.

In some cases, stormwater runoff from rooftops must be diverted into existing sewer lines. These closed systems are a dependable way of diverting excess stormwater away from the area of concern.
