Storm Drainage Improvement - Fir Street

The City is will be conducting Storm Drainage improvements on the drain along Fir Street; we will be converting the current open drain to a hard-piped drain system. The project will include surveying, staking, pipe placement, and the tear-down and rebuild of any existing fencing along the City easement within resident’s property line.

The surveying will be completed by Harmsen and Associates, construction will be completed by Sultan City staff. The project will include the installation of two catch basins and approximately 300 feet of pipe within the City’s easement. Project completion is slated for September 2019.

Decant Facility

A decant facility is a large concrete pad where stormwater waste (retrieved from catch basins and dry wells) can be properly disposed.

The construction of a new stormwater decant facility is in the planning stages. Stormwater drainage systems can contain above normal concentrations of contaminates such as dissolved heavy metals, heavy oil and gasoline. If left untreated, this sediment could result in contamination to the environment. The decant facility is in place to receive, process and dispose of those contaminates.
