Signs to Watch Out For

The implications of a poorly performing or damaged system are significant:

Pollution to the environment, particularly water
Impacts to health of people and animals
Costs of repairs, and in some cases fines•

Signs of Problems

Water draining away slowly from sinks, bathtubs and showers
Gurgling pipes when water is draining.
Foul odours coming from the area of the system
Water pooling or discolouration to grass around the disposal area
Grass is unusually green above the septic system outlet

Common Causes

Too much sludge or foreign objects blocking the disposal line
More wastewater coming in than the septic tank is designed for, washing solids into the disposal line
Low numbers of the bacteria required to treat the wastewater
Toxic chemicals (like bleach or commercial cleaners) entering the system, killing the bacteria
The mechanical parts (pumps and sensors) of secondary treatment systems breaking down
Roots invading the septic systems, causing leaks or blockages

How to respond

Contact a licensed plumber to have the cause of any problems identified. It is not recommended to get a pump out immediately as this may not be necessary and only mask the problem temporarily.
