Concrete Septic Tanks
Shay Murtagh also manufacture supply and install concrete septic tanks. These vary in sizes and are manufactured to SR6 1991 specifications. Although treatment systems are supplied there are still sites which are capable of using septic tanks. All septic tanks come complete with baffle wall, inlet and outlet collars and tees.
How do septic tanks work?
The septic tank serves as a settling basin where solids accumulate and gradually get broken down by bacterial action. Some of the solid waste is actually liquefied by natural bacterial decomposition, however the rest of the waste accumulates in the bottom as a sludge layer. Fats and oils float to the top and form a layer of semi-solid scum.
Usually a septic tank is connected to a percolation area of some kind. If properly maintained, a well designed system will last almost indefinitely. However, if it is neglected, it can back up and clog percolation areas.
