Pump the septic tank. This and any other measures that will reduce the volume of flow to the leaching bed will allow faster system recovery.
Lower the volume of water used. Limit the number of laundry and dish loads performed as well as the number and duration of showers. Repair any running toilets or leaking faucets.
Avoid using any harsh chemicals. Switch to cleaners that will not interfere with the bacteria that are breaking down clogs.
Stop using the garbage disposal.
Trim grass shorter or remove snow from on top of the leaching bed. This will increase the amount of sun that reaches the bed and decrease the amount of snow melt that will saturate the soil.
Improve drainage in the landscape. Ensure that no runoff from elsewhere in the landscape is directed onto the leaching bed.
Remove any tree roots that could be interfering with the pipes.
Use the septic tank as a holding tank if the clog is stemming from a frozen ground that does not permit drainage. Once the ground thaws, restore the flow to the leaching bed.
