When it comes to septic systems, there are probably more options for your Marlowe home than you realize. To a certain extent, the type of septic system you choose is determined by the particular conditions around your home. But it is worth learning about the various options so that you can make an informed decision about the kind of system you would like to have.
The more conventional types of septic systems fall into two categories – gravity and pressure distribution. A gravity system, as its name implies, makes use of the force of gravity to drain away waste from your home and into a drainfield.
Gravity systems use gravity to help treat the waste as well, so this type of system requires that you have a particular type of soil and enough space below the ground to allow for proper filtering. If the water table or a layer of hardpan is too close to the ground’s surface around your home, a gravity system may not be an option for you.
Another conventional option is a pressure distribution system. In this setup, a pump regulates the flow of waste from a storage tank to the drainfield. This is the optimal setup if you do not have enough below ground space for a gravity system as the pump makes sure that only the proper amount of waste can enter the drainfield at once and that the waste is distributed evenly when it is pumped in.
There are also several alternative types of septic systems. For instance, mound septic systems are another option to consider when you do not have enough space below ground for a gravity system. In a mound system, the drainfield is actually placed above the surface of the ground and a pump regulates the flow of waste to the field. This allows for adequate treatment before the waste reaches the water table.
Also an option in this type of situation is a sand filter system. This type of septic system incorporates a sand filter holding tank to treat waste before it is allowed out into the drain field. It is another way to make up for the fact that there may not be enough soil to provide adequate filtration but does not require that you build up a mound of earth on your property.
