Until recently, the OMNI RSF system required the area over the Filter Modules to be covered with a mulch type material only. The new OMNI RSF design is completely below grade and OMNI now has made this desing improvement available to existing system owners.
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.
OMNI is not responsible for the removal or disposal of any inappropriate materials located over the Filter Modules or system covers. All costs associated with the removal and disposal of such material is the sole responsibility of the system owner or other responsible party.
Sprinkler systems should not be installed in or within 10 feet of the RSF for three reasons:
- Damage to the Filter Modules by digging into it to install the sprinkler;
- The additional water load to the Filter Module; and
- The crossing of sewer and water lines is generally not permitted due to the potential for direct contamination of drinking water with sewage.
With lawn care equipment, such as riding lawn mowers or tractors, be careful not to travel on the Filter Module, and drainfield, or the downslope area when the soil is saturated, as during wet wintertime. Winter landscape work on the filter module and drainfield should be avoided to minimize frost penetration or compaction.
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 or asphalt sections or plastic sheets over the filter module also reduces the supply of oxygen necessary for the sewage treatment process.
Placing a vegetable garden over the drainfield is not recommended.
IMPORTANT:
Do not allow any surface runoff to be directed onto or around the sand filter, drainfield or the reserve area. Equally important, do not allow any construction or ground compaction in the reserve area or within 30 feet down slope from the drainfield.
