Waste Water Cert Flashcards
ACCESSIBILITY
S.C. Code Sections 44-55-1410 and 5-31-2010 authorizes county and municipal governments to determine if a wastewater treatment facility is accessible to properties. Where annexation or easements to cross adjacent property are required to connect to a wastewater treatment facility, the wastewater treatment facility shall not be considered accessible.
ALTERNATIVE SYSTEM
A system incorporating design modifications of the proposed subsurface wastewater infiltration trench area or geometry for the purpose of achieving compliance with required setbacks and offset to the zone of saturation and/or restrictive horizons. No such system shall be utilized unless the Department has established a specific standard.
ALTERNATIVE INFILTRATION TRENCH PRODUCTS
Products specifically designed to replace or eliminate the aggregate typically utilized in subsurface infiltration trenches. Such products must be approved for use by the Department and must adhere to required equivalency values established herein.
APPLICANT
A property owner, general contractor or agent representing the property owner, or developer who seeks a permit to construct and operate an onsite wastewater system.
CAMPGROUND
An organized camp in which campsites are provided for use by the general public or certain groups.
CANAL
An artificial waterway used for navigation, drainage, or irrigation.
COLOR CHARTS (Munsell System or equivalent)
Charts bearing various color chips established by a recognized color system which use three elements—hue, value, and chroma—to make up a specific color notation. The notation is recorded if the form of hue, value, and chroma (e.g. 10YR 5/6). The three attributes of color are arranged in the system in orderly scales of equal visual steps, which are used to measure and describe color accurately under standard conditions of illumination by comparing soil samples to color chips on various charts.
CONVENTIONAL SYSTEM
An onsite wastewater system that utilizes a network of conventional wastewater infiltration trenches installed in the naturally occurring soil for the treatment and disposal of domestic wastewater.
CRITICAL AREA
S. C. Code Section 48-39-10(J) defines critical area as the following: 1) coastal waters; 2) tidelands; 3) beaches; 4) beach/dune systems which are the areas from the mean high-water mark to the setback line as determined in S. C. Code Section 48-39-280.
CURTAIN DRAIN
A subsurface interceptor drain that is installed to collect and redirect seasonal groundwater as it flows through the soil profile to an appropriate discharge point.
DEPARTMENT
The South Carolina Department of Health and Environmental Control.
DITCH
A long narrow excavation, intended for the purposes of drainage and/or irrigation.
DOMESTIC WASTEWATER OR SEWAGE
The untreated liquid and solid human body waste and the liquids generated by water-using fixtures and appliances, including those associated with food service operations. For the purposes of this regulation, domestic wastewater shall not include industrial process wastewater.
EFFLUENT
The liquid discharged from a septic tank, effluent pump station, or other sewage treatment device.
EMBANKMENT
A bank of soil with at least two (2) feet of vertical height from top to bottom.
ENVIRONMENTALLY SENSITIVE WATERS
Outstanding resource waters (ORW), Shellfish Harvesting Waters (SFH), and Trout-Natural Waters (TN) as defined in R.61-68 and classified in R.61-69, and including lakes greater than forty (40) acres in size and the Atlantic Ocean, regardless of their classifications in R.61-69.
EXISTING SYSTEM
An onsite wastewater system, which has received final construction approval or has been serving a legally occupied residence or structure.
EXPANSIVE SOILS
Soils containing significant amounts of expansible-layer clay minerals (smectites) as evidenced in the field by classifications of “Very Sticky,” “Very Plastic” and where “Slickensides” are present when evaluated in accordance with the Field Book. Such soil horizons are considered to be restrictive for onsite wastewater systems.
FAILING ONSITE WASTEWATER SYSTEM
An onsite wastewater system that is discharging effluent in an improper manner or has ceased to function properly.
FIBERGLASS REINFORCED PLASTIC
A fibrous glass and plastic mixture that exhibits a high strength to weight ratio and is highly resistant to corrosion.
FIELD BOOK FOR DESCRIBING AND SAMPLING SOILS (Field Book)
A field guide published by the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) for making or reading soil descriptions and for sampling soils, as presently practiced in the USA.
FINAL TREATMENT AND DISPOSAL
Ultimate disposition of the effluent from a septic tank or other treatment device into the soil.
FLEXURAL MODULUS OF ELASTICITY
A measure of stiffness of a material.
FLEXURAL STRENGTH
A measure of the ability of a material to withstand rupture when subjected to bend loading.
GEL COATING
A specially formulated polyester resin, which is pigmented and contains filler materials, the purpose of which is to provide a smooth, pore-free, watertight surface for fiberglass reinforced plastic parts.
GREASE TRAP
A device designed to separate and store the oil and grease component of wastewater discharged from facilities that prepare food.
GLEYING
Bluish, greenish, or grayish colors in the soil profile that are indicative of markedly reduced conditions due to prolonged saturation. This condition can occur in both mottled and unmottled soils, and can be determined by using the Gley page of the soil color charts.
INDUSTRIAL PROCESS WASTEWATER
Non-domestic wastewater generated in a commercial or industrial operation that may or may not be combined with domestic wastewater.
LONG-TERM ACCEPTANCE RATE (LTAR)
The long-term rate, typically expressed in gallons per day per square foot of trench bottom area, at which a mature onsite wastewater system can continue to accept effluent without hydraulic failure occurring. This flow rate is a result of the interaction between unsaturated soil hydraulic conductivity and biomat resistance.
MOTTLING
Morphological features of the soil revealed as spots or blotches of different color or shades of color interspersed with the dominant matrix color.
NSF STANDARD #14
A National Sanitation Foundation Standard relating to thermoplastics, which have been tested and found satisfactory for potable water supply uses, and for drains, waste and vent applications.
ONSITE WASTEWATER SYSTEM
A system, generally consisting of a collection sewer, septic tank(s), and subsurface wastewater infiltration area, designed to treat and dispose of domestic wastewater through a combination of natural processes that ultimately result in effluent being transmitted through the soil, renovated, and ultimately discharged to groundwater.
Small Onsite Wastewater System
An individual system serving an individually deeded residence or business that generates less than fifteen hundred (1500) gallons per day of domestic wastewater. Management and maintenance of each system is the responsibility of the individual property owner.
Large Onsite Wastewater System (General)
An individual system that treats and disposes of domestic wastewater discharges in excess of fifteen hundred (1500) gallons per day.
Privately Owned Large System
A large onsite wastewater collection and treatment system that serves one piece of deeded property such as a school, adult residential care facility, rental apartment complex, shopping center, campground, mobile home park, office complex, etc. Management and maintenance of the system is the responsibility of the individual property owner.
Community (Cluster) System
A wastewater collection and treatment system that provides shared collection, treatment, and disposal of domestic wastewater from multiple parcels or multiple units of individually deeded property. Such a system might serve a small subdivision or a condominium complex. It is imperative with such systems that some form of common ownership and management be established and approved by the Department.
