Groundwater level extremely high in Rainbow

RAINBOW — After the recent rains, the groundwater levels in the Rainbow Valley are extremely high. The groundwater depth (how far the water is from the ground’s surface) is less than one foot! This means that the septic systems on the valley floor are in danger of failing.

Usually, the drain field, the part of the septic system that allows the wastewater from the septic tank to percolate (or soak) into the soil, sits several feet above the groundwater. This allows the wastewater to soak through the soil and be cleaned as it makes its way down to the groundwater.

When the groundwater levels are high, the drain field is actually sitting in the groundwater. These means that as more wastewater is pushed into the system from the home, the sewage (wastewater) can actually flow to the ground’s surface.

Another problem of high ground water levels is that the septic system can backup into the house and prevent the proper treatment and disposal of wastewater.

There are several things that you can do to prevent septic system failure during times of extremely high groundwater levels.

The first and most effective solution is to severely limit the amount of water that enters the septic system. This will help reduce the strain on a flooded septic system drain field and might prevent the wastewater from backing up into the house.

Several ways of reducing the amount of water entering the field is to take short showers, turn off the water when you are brushing your teeth or washing the dishes, do fewer loads of laundry and install high-efficiency toilets, showerheads and water fixtures.

By frequently pumping your septic tank and avoiding putting in anything toxic or non-biodegradable, you can help prevent septic system failure.

There are several symptoms of septic system failure. There might be a foul odor, pooling of water or muddy soil around the septic tank or drain field or your toilet or sink might back up after you flush or do a load of laundry.

If you suspect that your septic system has failed or is failing, contact the San Diego County Department of Environmental Health or a septic system professional.
