Frequently Asked Questions

Stormwater runoff is water from rain or melting snow that "runs off" across the land instead of seeping into the ground. This runoff usually flows into the nearest stream, creek, river, lake or ocean. The runoff is not treated in any way.

Local laws prohibit anything other than uncontaminated rain water from entering the storm drain system. Never pour anything into a gutter, street or storm drain.

A catch basin is a curbside receptacle whose function is to convey water from streets and other urban surfaces into the storm drain system. The design of this drainage structure includes a sump that captures and temporarily stores some pollutants such as oils and sediment. Regular maintenance to clean out the sump removes the stored pollutants and prevents them from washing further into the storm drain system and into receiving waters such as the Chehalis River.

Stormwater regulations define an "illicit discharge" as "any discharge to a municipal separate storm sewer that is not composed entirely of stormwater" (except discharges resulting from fire fighting activities and a few other categories). 

Common sources of non-stormwater dry weather discharges in urban areas include:

• Airports
• Apartments and homes
• Car washes
• Gas stations
• Landfills
• Restaurants

These so called "generating sites" and include, among other substances:

• Antifreeze
• Discharge sanitary wastewater
• Gasoline and fuel spills
• Motor oil
• Septic system effluent
• Vehicle wash water
• Washdown from grease traps

Although these illicit discharges can enter the storm drain system in various ways, they generally result from either direct connections (e.g, wastewater piping either mistakenly or deliberately connected to the storm drains) or indirect connections (e.g, infiltration into the storm drain system, spills, or "midnight dumping"). Illicit discharges can be further divided into those discharging continuously and those discharging intermittently.

By practicing healthy household habits, homeowners can keep common pollutants like pesticides, pet waste, grass clippings, and automotive fluids off the ground and out of stormwater. Adopt these healthy household habits and help protect our lakes, streams, rivers and wetlands.

You can help reduce pollution in our stormwater by avoiding the release of chemicals or pollutants into the waterways. You can also help by participating with the Grays Harbor Stream Team in cleaning up local waterways.

The ultimate goal of stormwater management is to maintain the health of streams, lakes and aquatic life as well as provide opportunities for human uses of water by mitigating the effects of urban development. To achieve this goal stormwater management strives to maintain the natural hydrologic cycle, prevent an increased risk of flooding, prevent undesirable stream erosion, and protect water quality.

Yes. The City regularly performs maintenance activities; including cleaning, of the storm drain system. In addition, the City crews are always available to respond to emergency situations where clogged storm drains result in flooding.

City crews clean out clogged catch basins throughout the year as part of on to going maintenance. Unfortunately, there are just too many catch basins and not enough time. Residents can reduce flooding in their neighborhoods by keeping material out of the storm drain system or clean debris around the catch basin when performing landscape maintenance.

Those buttons were placed above catch basins as a reminder to citizens that the catch basins drain to the streams, and should not have any discharge into the catch basin that is not rainfall.

The only discharge that is allowed in catch basins is rainfall.

The Stormwater Rate is $8.69 per month.
