Its not a glamour’s job, but a necessary one. With septic tanks / WwTP’s being inspected since 2014 by local authorities, there are more reason why you should desludge ( empty & clean) your on site septic tank or waste water treatment plant. As the waste enters the unit, it is broken down by various means. As the waste is broken down, the sludge settles out on the bottom of the tank, with a liquid layers in the middle of the tank with a scum layer on top. Over time, the level of sludge will rise, reducing the important liquid layers and therefore reducing the ability of the tank to work properly. If the level of sludge levels rises significantly, then the sludge will enter the percolation area, causing the percolation area to break down. Sludge will block the network of pipes that enable the distribution of the water to achieve the standards of discharge required under the EPA regulation. All septic tanks / WwTP’s have a percolation area or soak away to assist with the discharge of the water back into the existing ground. To ensure the septic tank / WwTP and percolation areas work efficiently to produce clean water prior to discharge to the ground, it is important they are serviced. The water that is discharge back into the ground from the percolation area will finally migrate back into the water table. This water table is the only mean of a clean water supply to our homes.
As per the condition of the grant of planning permission, you are required to maintain and services your on site septic tank /WwTP. If a septic tank / WwTP is de sludged every 2 years, then you are maintaining your system and reducing your overall cost.
Under section 70 of the water services act, the responsibility falls to the house owner.
