Identifying Common Septic Tank Problems

The main things to look out for when inspecting your septic tank

1How do I know if i have a septic tank problem?
There are some sewage systems that are easy to diagnose as “not working” and there are also some systems that may need a trained eye to make the call. Below are some signs of sewage systems that may not be working:
- Blockages in manholes or slowly draining toilets.
- Wet patches in the garden - even in dry weather
- The septic tank requires frequent emptying / desluding.
- Storm or Roof water entering the septic system or leaking manholes.
- Wet areas in the garden around the septic tank / percolation area.
- Lush green grass around the septic tank/soakaway, even during dry weather.
- The presence of nitrates and bacteria in your drinking water test results.
- The septic tank is connected to a ditch, stream or river. Odours from the septic tank or around the house
If your still not sure you can have your sewage system visually assessed by Sepcon

If I have a septic tank problem - what do I do next?

1I know my Septic Tank is not working, what is the first step?
The first step is to give us a call on 01 6287300 to arrange a site visit with our highly experienced Project Manager to view the extent of the issue.
There is not charge or obligation associated with the initial site visit.
We will arrange to meet you at a time that suits you and the Project Manager will be your direct Point of Contact throughout the entire upgrade process.
2What is a Percolation Test?
A percolation test is carried out to determine what type of sewage treatment system will be suitable for your property. The percolation test provides us with the soakage value of the soil, what depth the water table or bed is present at and a number of other factors. With these results and the assistance of Geological mapping we can provide you with the most suitable sewage system for your site.
3Why do I need to carry out a Percolation Test?
Percolation tests are carried to determine the size required for the percolation area. The soakage of the soil in every site varies. Some sites have good soakage and some are very poor.
Therefore a single solution can't be offered to everyone. It is crucial to carry out a percolation test in order to know how good your soil soaks and to determine the maximum height of the water table (in order to maintain relevant separations as per the EPA Code of Practice 2009).
A percolation test is also required by law in order to apply for planning permission for a new build. Sepcon have a dedicated team that will assist in providing the relevant site assessment information and documents in order to lodge your planning application.

4What is the difference between a Septic Tank and a Sewage Treatment Unit?
A septic tank normally consists of two chambers. The first chamber holds the solid waste and the second chamber holds the partially treated effluent. The effluent then enters the percolation area where further treatment takes place. Septic tanks are suitable for sites with a good soil soakage rate.
A sewage treatment unit normally consists of 3 or more chambers. The first chamber holds the solid waste, the second is where the effluent treatment takes place and the the third is the final settlement chamber. Treatment units are ideals for sites with poor soakage as the effluent quality is better upon discharge to the percolation area.

Upgrading & Septic Tank Replacement

1How long does it take to install a new sewage system?
It normally it takes us no more than 3 days to install a new domestic sewage treatment unit and a percolation area. Sites with restricted access or more challenging projects may be 1 or 2 longer.
2Do I need to move out of my house when you are installing a new system?
No. Definitely not. The installation of your new sewage system is a painless process with Sepcon.
When we are making the connection from the sewage pipes to the new tank we ask that you refrain from using the toilets or sinks for about 2 hours.
3What happens to my old septic tank?
When we install your new system we empty and decommission the old septic tank.
The effluent and sludge contents are disposed of in a licensed facility and evidence of the same is also provided.
Any internal mechanical parts are removed and disposed of; and the old tank then broken in upon itself and filled with clay or suitable material.
