What is a drainage field?
A drainage field is a waste water treatment process that removes impurities and contaminants from the effluent released by a septic tank.
Septic tanks aren’t something that work on their own. They require drainage fields to treat the effluent within the tank. In fact, since January 2020 all septic tanks were prohibited from discharging directly into a watercourse.
Conclusion: A drainage field must be installed alongside a septic tank.
How long do drainage fields last?
This depends upon how well drainage fields are maintained. One that is regularly serviced by a reliable expert company can have a life expectancy of up to 50 years.
How to tell when your drainage field needs replacing
Water backs up
When water backs up in your drains then you can consider the possibility that your drainage field needs replacing. In this case the WC will not be working properly, requiring several flushes to clear.
Bad smells
If you have a nasty odour hanging around your drains or property then your drainage field has probably failed. The smell is the result of the drain field’s liquid waste collecting in the soil.
Noises
Gurgling and other noises are often a sign that there is a blockage in your drainage system. These may come from the WC, or other plumbing fixtures.
Puddles
Another way to tell that your drainage system has failed is if puddles of water are appearing in your garden.
Sludge or slime
If you see a black slimy substance on the ground above your septic tank or a significant about of scum or sludge within the tank itself, this is a serious indication that your drainage field needs replacing.
Why is it important to replace your drainage field?
Because drainage fields are there to process contaminants from your septic tank it is vitally important that they work efficiently. If they are not in good order they won’t process water any more and that means that pollutants can make their way into the groundwater. Aside from nasty smells and black sludge, you will be seriously putting the health of those who live with you in jeopardy, especially if you have a private well that uses the groundwater as your drinking water.
