Arkansas Onsite Wastewater Rules And Regulations Quiz

The statement suggests that it is mandatory for all new pump systems to have a high water alarm installed. This implies that the installation of a high water alarm is a requirement for new pump systems. Therefore, the correct answer is True, indicating that it is indeed necessary for all new pump systems to have a high water alarm installed.

Advanced systems will require a maintenance contract, but ultimately the septic system is considered part of the structure and therefore the owner's responsibility.

LPD stands for Low Pressure Distribution. This term refers to a method of distributing liquid or wastewater in a system using low pressure. In this system, the liquid is evenly distributed through a network of pipes or channels at a lower pressure than traditional distribution methods. This allows for more efficient and controlled distribution, reducing the risk of damage or overloading. LPD is commonly used in wastewater treatment systems and can help to improve the overall performance and longevity of the system.

A Designated Representative can design a septic system. This individual is specifically designated and authorized by the relevant authorities to create plans and designs for septic systems. They have the necessary knowledge and expertise in the field to ensure that the system is properly designed and meets all regulatory requirements. This role is important in ensuring that septic systems are designed in a safe and efficient manner.

The 100ft setback is between the high-water mark (not the current level) and all parts of the septic system including the tank.

These are the Brief, Moderate and Long SWT that you identify in a soil test pit.

A resort with 25 full time employees and 200 maximum occupancy would require a Class V Injection Well permit from ADEQ. This is because the resort has a larger capacity and higher occupancy, which means there would be a higher volume of wastewater generated. A Class V Injection Well permit is required for systems that dispose of wastewater through underground injection wells, which is likely necessary for a resort of this size to properly manage and treat its wastewater.

Soil mottling refers to the presence of contrasting colors or spots in the soil, which can indicate poor aeration and drainage. When soil is poorly aerated, it means that there is not enough oxygen available for the roots of plants to thrive. Additionally, if drainage is impeded, excess water can accumulate in the soil, leading to waterlogged conditions that are not conducive to healthy plant growth. Therefore, the statement that soil mottling generally indicates poor aeration and impeded drainage is true.

The setback to a pond on a neighboring property is 100 ft. This means that there must be a distance of 100 ft between the pond and any structures or boundaries on the neighboring property. This setback is likely in place to ensure that there is enough space for the pond to function properly and to prevent any potential issues such as flooding or contamination from nearby structures.

The statement is true because when sizing a septic system using soil morphology, three primary considerations are bedrock, hydraulic conductivity, and seasonal water tables. These factors are important in determining the suitability of the soil for wastewater treatment and absorption. Bedrock can affect the depth and placement of the system, while hydraulic conductivity determines how quickly water can move through the soil. Seasonal water tables indicate the level of groundwater and can impact the system's performance. Therefore, considering these factors is crucial in designing an effective and efficient septic system.

An installer can use either waterproof wire nuts or heat-shrink butt connectors when wiring a junction box. This means that both options are acceptable and can be used interchangeably. Waterproof wire nuts provide a secure and watertight connection, while heat-shrink butt connectors offer a more durable and long-lasting connection. The choice between the two depends on the specific requirements of the installation and the preferences of the installer.

The correct answer is 6" gravel on bottom, 4in perforated pipe, 2 more inches of gravel on top of pipe, and 6 inches of natural soil cover. This is the correct configuration for a standard pipe and gravel absorption trench. The gravel on the bottom provides a stable base for the trench, while the perforated pipe allows for the drainage of water. The additional layer of gravel on top of the pipe helps to distribute the water evenly, and the 6 inches of natural soil cover provides further filtration and protection for the system.

A setback to a structure refers to the minimum distance that must be maintained between the structure and the property line or neighboring buildings. In this case, the correct answer is 10 ft, which means that the structure must be at least 10 ft away from the property line or neighboring buildings. This setback requirement ensures safety, privacy, and proper use of space between different structures.

To have an OMP contract, all three options mentioned (Home with Drip Dispersal System, Office with a holding tank, and Restaurant with an ABG) are required. This means that all types of properties, including residential (home), commercial (office), and hospitality (restaurant), must meet the specified criteria in order to be eligible for an OMP contract.

Different trench products will have different width requirements. A standard pipe and gravel trench is 18"D x 24"W. 6 in gravel on bottom + 4 in gravel around pipe + 2 in gravel on top of pipe = 12 inches total. 6 inches of natural soil/backfill on top. 2 inches of maximum allowable "fall" from the beginning to end of the trench.

The DR can inspect the installation of a system, but cannot issue the Permit for Operation. They would still collect shots, sign the "Inspected By" on the EHP-19 and turn into the LHU. Only then will we sign a Permit for Operation.
The Homeowner has the right to install their own septic, but not to design it (exception is the 10 acre exemption)

After the septic system is installed as designed and inspected, the EHS will issue a Permit for Operation. This permit allows the owner or operator to legally operate the septic system and ensures that it meets all necessary health and safety requirements. It signifies that the system is in compliance with regulations and can be used for its intended purpose.

An acre is a unit of area commonly used in the United States and other countries for measuring land. It is equal to 43,560 square feet. Therefore, the correct answer is 43,560.

Just an FYI: always a minimum of 2 absorption lines. 100 ft maximum.

The secondary areas weren't required until July 1, 1977. See Memo EHGS 0015.

A freshly applied soil cap is expected to settle over time by approximately 25%. Settlement occurs as the soil particles compact and rearrange themselves under the weight and pressure of the overlying materials. This settling process can continue for a certain period until the soil reaches a state of equilibrium. The given answer suggests that a 25% settlement is expected, indicating that the soil cap will compact and decrease in height by a quarter of its original thickness over time.

aka Hydrosplitter and Spider Valves.  This is to prevent the small orifice holes from clogging. 

After a site evaluation is complete and the design is approved, the EHS will issue a Permit for Construction to the applicant. This permit allows the applicant to proceed with the construction activities on the site. It indicates that all necessary environmental, health, and safety requirements have been met and that the construction can be carried out in compliance with regulations. The Permit for Construction is typically required before any construction work can begin on a site.

A Septic System Installers license expires on December 31 each year. This is the last day of the year, and it is the standard expiration date for many licenses and permits. It allows for a clear and consistent renewal process, ensuring that license holders are up to date and meet the necessary requirements for the following year.

Depletion=removal
Concentrations=accumulations

"Land divided or proposed to be divided for predominantly residential
purposes into such parcels as required by local ordinances, or, in the absence of local
ordinances, subdivision means any land which is divided or proposed to be divided by a
common owner or owners for predominantly residential purposes into 3 or more lots or
parcels, platted or unplatted units any of which contains less than three acres, as a part of
a uniform plan of development."
However, if the city or county considers them a formal subdivision, then we will also require subdivision review. Follow whatever regulation has the most restrictive definition of a subdivision.

Dose Volume divided by GPM = minutes.

The minimum setback to a private drinking water well is 100 ft. This means that any potential sources of contamination, such as septic systems or chemical storage tanks, must be located at least 100 ft away from the well. This distance helps to protect the quality and safety of the drinking water by reducing the risk of contamination from nearby activities or substances.

This may not be the best version of the definition. The point is that the OWS cleans up the wastewater and hopefully prevents any pollution of groundwater.

The effluent must have contact with chlorine for at least 30 minutes to inactivate most pathogens.

Sludge is what sinks. Scum is what floats. The Clarified Effluent is the layer in the middle that has less solids and is discharged to the absorption field.

Holding tanks can't be used for either food service establishments or residences. Usually only used in light-use commercial settings because pumping gets expensive. Can only be used when a standard septic system can't be installed.

Composting toilets are designed to handle solid waste and decompose it into compost. However, they are not designed to handle gray water, which is wastewater from sinks, showers, and washing machines. Gray water contains soap, grease, and other chemicals that can interfere with the composting process and potentially harm the environment. Therefore, it is true that gray water cannot be discharged into a composting toilet.

The minimum setback to a property line for a standard system is 10 ft. This means that when installing a standard system, there must be a minimum distance of 10 ft between the system and the property line. This setback requirement is in place to ensure that there is enough space for maintenance and repairs, as well as to prevent any potential issues or conflicts with neighboring properties.

less than 6 inches of fall across the absorption field (first line to last line) is a Flat Ground System. More than 6 inches is a sloping ground system. This all relates back to how you achieve Maximum Storage.

See Memo EHGS-0010 2-3-2009 issued by Terry Paul.

An interceptor drain serves two purposes. Firstly, it helps to lower a high water table to a depth of 18 inches for sizing purposes in soils with less than 30% clay and more than 3% slope. This is important for ensuring the proper functioning of the septic system. Secondly, it prevents excess ground or surface water from influencing the septic system. This is crucial as excessive water can overwhelm the system and lead to malfunction or failure. Therefore, the correct answer is both.

The setback to a pond that is on your property is 50 ft. This means that there must be a distance of 50 ft between the pond and any structures or property boundaries. This setback is likely in place to ensure that there is enough space for the pond to function properly and to prevent any potential issues such as flooding or contamination.

Act 402 of 1977 is the actual law that gives ADH power to address onsite wastewater systems. This law specifically grants the Arkansas Department of Health (ADH) the authority to regulate and manage onsite wastewater systems. It outlines the responsibilities, requirements, and procedures to be followed for the proper management and operation of these systems. The other options listed, such as the Clean Water Act, General Sanitation Act of 1977, and Rules and Regulations Pertaining to Onsite Wastewater Systems, are not the specific laws that grant ADH this power.

A cleanout is required every 100 ft between the stubout and the septic tank.

The purpose of the minimum 5 ft of squirt height in LPD systems is to keep the orifice holes scoured out. This means that the force of the squirting wastewater helps to prevent any blockages or build-up in the orifice holes, ensuring that the system continues to function properly. This requirement helps to maintain the efficiency and effectiveness of the LPD system by preventing any potential clogging issues.

The purpose is to be sure that there is plenty of room for a home, pools, etc AND for primary/secondary absorption lines to be laid out on contour.

12 inches total: 6 inches on bottom + 4 inches around pipe + 2 inches on top of pipe

Literally just splitting the flow into 7. You will rarely need to know this, but is test required.

The 5 ft of solid pipe at the beginning of an absorption trench prevents any water from back flowing out of the trench, traveling down the tight line trench and collecting at the bottom of the system.

The proposed septic system is 158 ft from the high water mark of the lake, which is greater than 100 ft. Additionally, it is stated that the land is 3 miles from a public water intake, which is greater than 1/4 mile. Therefore, based on these conditions, pre-treatment will not be required as part of the design.

Research has shown that after 6 lines, equal distribution isn't effectively achieved with a gravity DBox system. Mechanical dosing helps with this by delivering a set amount of water all at once instead of a steady trickle. Mechanical dosing means a pump, siphoning tank, dipper d-box or other method.
