How Septic Tanks Work
Unlike cesspits, septic tanks are designed to allow liquors to flow through the tank and enter the surrounding land or water course via a soak-a-way
without causing damage to the environment. Waste waters enter the tank and the flow is reduced through a series of baffles allowing the solids to sink
to the bottom. Additionally, smaller particles float to the surface creating a scum. By holding the water in the system, suspended solids are removed
and much of the sludge decomposes through natural aerobic and anaerobic processes.
In turn the semi-treated liquor is allowed to exit the tank and leach to nearby land via a soak-a-way system.
Emptying Frequency
There is no hard and fast rule, but for a septic tank to work efficiently the sludge (solids) needs to be removed on a regular basis. The frequency of
“de-sludging” will depend on size of the property and the number of occupants. However, most will require emptying at least once a year to maximise the available void.
Do’s & Don’ts
• Don’t dispose of: commercial chemicals, medicines, disposable nappies, incontinence pads or feminine hygiene products down the wc.
• Don’t use large quantities of biological cleaning agents and bleach.
• Don’t hose down the baffles and media areas of the tank. It is important for the bacterial media to remain and restart the biological process.
• Do have the tank “de-sludged” regularly.
• Do use biologically friendly products.
• Do take advantage of our Regular Service Discount Scheme rates.
Problems and Remedies
Problem: Odour |
Cause: a) Sludge particles leaving the septic tank and entering the soak-a-way.
) Sludge has blocked the exit and the tank is overflowing.
Remedy: Have the tank “de-sludged” or emptied. Call 0500 053 429.
|
Problem: System backing-up |
Cause: Blockage in the in-let pipe, blockage in the out-let pipe. Soak-a-way blocked.
Remedy: Clear in-let and/or out-let pipe. Remove and replace soak-a-way media. Call 0500 053 429. |
Problem: Tank refilling immediately after emptying |
Cause: High water table. Ground water enters the tank via the soak-a-way.
Remedy: None.
|
Problem: Tank refilling immediately after emptying |
Cause: High water table : Tank ruptured allowing ground water to enter the tank.
Remedy: Clear and clean tank, inspect, repair or replace. Call 0500 053 429.
