Pump Chamber and Pump: A Pump Chamber and Pump may be used to send the sewage to a higher, more suitable disposal area on the property. (Pump systems include extensive electrical controls, alarms, and excess storage capacity to ensure proper timing of pumping and safeguards in the event of power failures, pump breakdowns, or system overloading.)
Effluent Filter: An Effluent Filter may be set in the tank to help ensure that solids don't escape from the tank to clog the leaching device.
Inspection Risers: Inspection Risers are vertical pipes which extend from the bottom of the leaching device to above the ground surface, which can be opened and inspected to determine the level of the effluent in the trench.
Distribution Box or Flow Divider: A Distribution Box or Flow Divider ensures that the sewage is evenly distributed to all parts of the leaching system. If this is not installed properly, one part of the system can be overloaded and fail, while other parts remain dry.
Diversion Valve: A Diversion Valve is used in older systems to cut off the flow of sewage to part of a leachfield, potentially allowing it to rest or recover while the other part of the leachfield is being used.
Pressure Distribution Systems: Pressure Distribution Systems may be used in conjunction with pumps to deliver sewageunder pressure evenly to all parts of the leaching device.
Chamber Leaching Devices: Chamber Leaching Devices may be placed in trenches instead of gravel and perforated pipes. An example of this is the Infiltrator Device.
Enhanced Treatment Units: Enhanced Treatment Units may be used in place of, or in addition to, the septic tank to provide a much highler level of effluent treatment before the sewage is discharged into the soil. Examples of these are sand filters, or proprietary devices such as Multiflo units, Microsfast Systems, and Clearwater Systems.
Mounded Bed Systems or At-Grade Systems: Mounded Bed Systems or At-Grade Systems are engineered leaching devices which provide for sewage disposal right at, or above the natural ground surface for use in areas where there are high groundwater levels
Seepage Pits: Seepage Pits are leaching devices that consist of a circular pit 3-4 feet in diameter drilled 20-40 feet into the ground.
Greywater Sumps: Greywater Sumps are normally small, rock-filled leaching devices designed to dispose of sewage from clothes washers, sinks, showers, or other sources that do not contain toilet waste (blackwater).
Haulaway System: A Haulaway System is used where standards for in ground sewage disposal cannot be met. Sewage is contained in a holding tank for regular removal by a septic tank pumper.
