Experts in Septic & Drainage Repairs and Maintenance
Most old septic systems rely on a trickle discharge, essentially what goes in comes out. Since the soakage is only receiving a small amount of water at a time, it tends to soak away at the beginning of the soakage area; until the constant flow causes a build up of slime and sludge and blocks the ground, then it progresses along a bit further; this is called ‘creeping failure’. Over a number of years the entire area will block up.
We can reinstate your soakage area to it’s original state, as long as we know where it is and how big. It is important that we don’t change it significantly, as this will require a building consent. We will dig it up and use new materials to reinstate it.
In many cases, the most future proof option is to bring the soakage up to standard and getting it approved by council, as this will improve the current operation and future sale value of your property. By doing this we can also add a dosing module to the septic system, improving the loading of the soakage and increasing it’s life span.
No Septic Access Hatch
To meet current regulations, every septic should have a access manhole. Many old septic’s had a concrete hatch buried under the ground; the suck out person would have to dig this up to fully suck out the tank.
We can add a riser and lid to an existing septic, improving the tank access.
Ground Water Backflow
As I mentioned already, most old septic’s rely on a trickle discharge. This can have another complication; if there is high ground water, it can flow back through from the soakage into the septic. This typically occurs on flat sites where the water can’t get away easily. In this situation, large rain events can prevent the septic discharging correctly, in the worst case resulting in sewage overflowing out of the tank onto your section.
This can be remedied by adding a dose tank to the end of the septic and pumping it into the soakage area. The pump forces the water into the soakage area, where it is unable to return to the tank.
We also have smaller gravity dosing modules to improve the dosing of soakage areas.
