The OMNI RSF system requires the area over the Filter Modules to be covered with a mulch type material ONLY.
The system owner is responsible for maintaining any landscaping features, including any mulch located over the OMNI Filter Modules and keeping required covers accessible and/or to grade.
Sprinkler systems should not be installed in or within 10 feet from the RSF for the following reasons:
Take care not to ride over the Filter Modules and tank covers with lawn care equipment, such as riding lawn mowers or tractors.
Any landscaping you choose to do must not adversely alter or disturb the Filter Module, drainfield or the soils around them. You should not place fill soils over the Filter Module. This will block airflow into the Filter Module and greatly reduce the effectiveness and shorten the operating life. Placing concrete, asphalt sections or plastic sheets over the Filter Modules also reduces the supply of oxygen necessary for the sewage treatment process.
Do not allow any surface runoff to be directed onto or around the Filter Modules or drainfield.
