Maintenance
The Modular Wetland System - Linear was designed with the input of various city maintenance crews. We have designed a system that is simple and fast to clean and maintain. The system contains four treatment stages, each with its own maintenance procedure. This 'treatment train" concept minimizes maintenance costs because each treatment stage protects the next stage from clogging. We designed the system to either be cleaned by hand or with the use of a vac truck. Below is an overview of each stage. To download the maintenance guide please click on the following link.
Stage 1 - Screening
Trash & debris are captured in a screening filter just below the grate or curb opening. To service this, simply remove the grate or manhole and vacuum out the debris. To service the next stage simply remove the screen filter.
Stage 2 - Hydrodynamic Separation
Sediments and TSS are captured in a separation chamber in the bottom of the catch basin. To service, simply use a vacuum truck to remove captured sediment.
Stage 3 - Primary Media Filtration
Fine TSS, associated pollutants, hydrocarbons, dissolved metals, and a portion of the nutrients and bacteria are captured by a perimeter filter containing BioMediaGREEN. To service, simply remove media shields, remove spent media blocks and replace with new media. To order media call or send us an email.

Stage 4 - Wetland/Bioretention Filter
Nutrients, metals, and bacteria are captured in the wetland/bioretention filter. This is the portion of the media that is vegetated. While the above stages should be serviced on a annual basis, the wetland/bioretention filter can go 5 to 20 years before requiring media replacement. The plants should be trimmed annually.
