In some instances, homeowners must install septic tank systems where there is minimal soil. In this case, a sand mound system may be installed. The mound for the system represents a drain field, which is elevated above the normal soil surface. This is done by using sand fill material.
How a Mound System Works
A septic tank repair contractor in Milton, DE often recommends this type of system when a system is old and can no longer be repaired. The sand fill that is used displays a series of pressurized pipes within a bed of gravel. The effluent from the septic tank is directed through the pipes with a pump.
A More Natural Process
According to septic tank repair contractor professionals, pumping the effluent in measured doses ensures that the effluent will be distributed uniformly within the gravel bed. The treatment of the effluent takes place as it travels through the gravel or sand and into the soil.
Therefore, this type of treatment-based septic system is made up of pressurized lines that lie in a mound of gravel and sand, all of which is above the surface of the ground. To construct the system, a septic tank repair contractor must place at least one and a half feet of permeable soil over a restrictive tier for new construction.
Periodic Servicing
As a result, the system can now be installed on construction sites that were once thought to be unsuitable due to poor soil depths. Because the system is complex, it regularly needs periodic servicing. Doing so will ensure that the system’s performance standards are continually met.
