Definitions
Centralized Sewer Collection
A system of lateral, main and truck sewers, connected together to convey sewage from individual properties to a central location for treatment and disposal.
Effluent Reuse
The water that is collected from the sanitary sewer service and treated to a quality level referred to as Class A+. The reclaimed water can be used for certain beneficial purposes such as irrigation of agricultural crops and landscaped areas such as parks or golf courses, drinking water for livestock, dust control, and street cleaning.
Equivalent Residential Units
Is defined based on water meter/service line size, (i.e. all 3/4 inch services are considered to be a single ERU).
Interceptor
A device designed and installed so as to separate and retain deleterious, hazardous or undesirable matter from normal wastes and permit normal sewage or liquid wastes to discharge into the lateral sewer by gravity.
Lateral Sewer
The part of the horizontal piping within a public street or sewer right-of-way, connecting a building sewer to a main sewer. This portion of the line is the responsibility of the property owner.
Manhole
A hole, usually with a cover, through which a person may enter a sewer system to perform maintenance. An access point for the collections system.
Ruck System
A Denitrification system that separates the blackwater (toilet and kitchen sink) and graywater (all other household water) into two separate septic tanks. The blackwater septic tank effluent has a substantial reduction in biological oxygen demand (BOD), and suspended solids. Additionally, the treated effluent is well nitrified containing dissolved oxygen. The sand filter effluent is directed to the gray water septic tank mixing with the remaining wastewater where the denitrification process begins. The denitrified effluent is then discharged to a conventional leaching field.
Septic Tank
This allows for the settling of solids. This is accomplished by providing inlet and outlet baffles to reduce the velocity of liquid moving through the tank and to prevent solids from leaving the tank. A septic tank does not provide denitrification.
Sewage Pumping Station
Any works or devices used to raise sewage from a lower to a higher elevation, or to overcome friction in a pipe line.
Treatment Capacity Fee (TCF)
The fee is $2,000 per equivalent residential unit.
User Charge
Charges assigned to each user which defray a proportionate share of the cost of operation, maintenance, and capital costs of the sewerage system, often referred to as sewage disposal service charge.
