The 75-foot setback from property lines is measured from the lagoon's nearest shoreline. Often, however, certain trenches or low points in the distribution system receive more effluent than others. (636) 583-6384. For each question, indicate your risk level in the right-hand column. If you assume that every person in the house uses 25 to 75 gallons of water a day, four people can fill a 1,500-gallon tank in five to fifteen days. Figure 7a and Figure 7b shows the proper placement of the curtain drain to protect the sewage lagoon. Related Information: Lawrence . The amount of wastewater flowing out of a house may average 100 to 200 gallons or more per bedroom per day multiplied by the number of bedrooms in the home. Have your drinking water tested annually for coliform bacteria and nitrates. Leveling devices on the distribution box help ensure an even flow of wastewater to every trench. Aerobic treatment units operate much like a municipal sewage treatment plant, where wastewater is mixed with air, promoting bacterial digestion of organic wastes and pathogens. Soil microbes need oxygen to digest wastes quickly. <>>> When submitting an application, additional details and requirements are identified inside the application. Wet, spongy ground or lush plant growth may appear near a leaky septic tank or failing drainfield. The top-seal tank is formed into a one-piece tank portion with a concrete lid secured to the open top with mastic sealant. If the 12 inches of water completely drains away in less than 10 minutes you can begin the percolation testing immediately. To protect the drainfield: Foul odors in your home or yard tell you that your system is not working well. The liner should be at least 30-mil (0.03-inch) thick and is typically made of laminated rubber compounds.

Prospective home buyers can also request their home builder obtain a permit and have inspections conducted through our Fire District. When a properly sized septic tank precedes the lagoon, the lagoon water surface area may be reduced by up to 20 percent if approved by the regulatory agency. Missouri Department of Natural Resources Water Protection Program P.O. Soil morphology evaluations are preferred in the Missouri Ozarks because they are more reliable, more informative and generally less expensive than percolation tests. Many were forced to find other construction jobs to keep them afloat and many entered other industries entirely. For more information on our Septic Program please call (417) 466-2201. In 2010, Lincoln County Fire Protection District ended the requirement for mandatory permits and inspections of newly constructed residential homes, however the Residential Code remains in full effect. In order to obtain a building permit for construction of any building . In the basement, look for the sewer pipe leaving the house and note the direction in which it goes through the wall. From there to the lagoon, pipe with SDR 35 thickness or greater is adequate. Here are a few: Use Assessment 3 in the work sheet to begin rating your risks relating to system inputs. The sum of the solid layers (sludge plus scum) takes up more than half of the tank capacity, The top of the sludge layer is less than 12 inches below the outlet baffle or tee, or. Along with pumping, cleaning, and repairing septic tanks, these Lincoln County locations may also service sewers, portable toilets, cesspools, and grease traps. Departments. 4 0 obj (Low-flow fixtures are required in some localities.). If the location of your system is not in your home records, then a previous homeowner, county health department, or pumper's records may hold the answer. Tab will move on to the next part of the site rather than go through menu items. The Health Department regulates and reviews storm-water drainage, wastewater treatment and solid waste treatment. Soil morphology evaluations are preferred for sites where soil conditions suggest a potential pollution risk to groundwater. Percolation, or "perc," tests are best suited for sites that do not have significant groundwater pollution potential. The site navigation utilizes arrow, enter, escape, and space bar key commands. Contrary to popular belief, robust residential building codes do exist in large portions of unincorporated Lincoln County. At 30-minute intervals, read the drop in water level to the nearest 1/8-inch increment (1/16-inch increments are recommended). In areas with severe geologic limitations, restrictive layers such as fragipans must be a minimum of 12 inches thick and must not be breached by excavation equipment during construction. 0000000669 00000 n local Missouri authority for more information on how to get The soil filters out larger particles and pathogens, which eventually die off in the inhospitable soil environment. Septic System Construction. The biological breakdown of wastes in a septic tank's anaerobic (oxygen-deprived) conditions is relatively slow. % . Slope the pipe 1/4 inch per foot (1/8 inch per foot minimum) toward the tank. The effluent moves slowly out of the trench and is absorbed into the soil. The National Onsite Wastewater Recycling Association developed this folder to provide septic system owners with simple operation and maintenance guidelines to ensure their system will work properly. Missouri regulations do not permit surface discharge of wastewater effluent. The department achieves this through education, individual registration, inspections, and a system for reporting and resolving problems. Therefore, before beginning a septic system project, contact the relevant During drier weather, you may need to prefill by pumping water from the house water well or nearby pond. Keep in mind, the friend of the family or the cheapest bid may not always be the best choice. (These types of systems are discussed further below.). The greater the distance, the lower the chance of contaminating the water supply.

After Hours Essential Service Phone Numbers. Don't make or allow repairs to your lagoon system without obtaining the necessary permits. contact| Installation may require the services of a professional liner contractor, although homeowner-installable liners are available. If surface runoff is a concern, completely fill the trench with gravel to the ground surface. The process that takes place in a lagoon is a natural one, with microscopic plants and animals coexisting and dependent on each other. When wastes are broken down, some of the material is given off as gases in the air and small amounts of solids settle to the bottom of the lagoon. Do keep your septic tank and distribution box accessible for pumping and adjustment. Anaerobic conditions occur when soils are poorly drained, groundwater levels are high, surface runoff saturates the drainfield, or excessive amounts of water are used in your household. Under suitable conditions, beneficial soil microbes and natural chemical processes break down or remove most of the contaminants in the effluent. Do you have a septic system or other on-site system to treat wastewater? approved, the Department of Health and Senior Services is responsible for 113 Lincoln County - - 115 Linn County - - 117 Livingston County - - 121 Macon County - - 123 Madison County - - 125 Maries County - - Effluent can be fed into the pipes by gravity or by a pump.

Freeboard, or the distance from the three-foot operating level to the top of the berms, should be 24 inches (18 inches minimum) to keep surface runoff from entering the lagoon. We are sorry but the community room is no longer open for public events. With suitable climate and soil conditions, other alternative systems such as evapotranspiration systems, constructed wetlands, spray irrigation, lagoons or mechanically aerated systems for household wastewater treatment are approved in some localities. Enter and space open menus and escape closes them as well. However, as in any other industry, there are also less than reputablecontractors who do not care or dont know the standards. Use water-saving features in faucets, shower heads and toilets. Do take leftover hazardous chemicals to an approved hazardous waste collection center for disposal. You can find the application and information under "Permits and Forms" below. The majority of these codes and requirements pertain to fire and life safety and well as the protection of property and the investment of the homeowner. Any outlet filters should be rinsed off. There are subtle differences in the requirements and rules depending on the county in which you are based. In addition, an alarm should be installed on holding tanks or pumping chambers to warn you if the tank is nearly full. A 12-inch total thickness of compacted clayey soil on the bottom and up the inside slopes of the lagoon will generally provide an adequate seal. Inspection pipes at the top of the tank are for inspecting the inlet and outlet pipes, baffles and tee pipes. Additives containing solvents to unclog your system can kill the microbes needed to digest wastes in your septic tank and drainfield. In all septic tanks, the inlet and outlet pipes should be at least 4-inch diameter Schedule 40 PVC, cast-iron or other approved pipe and be protected by baffles or sanitary tees made of acid-resistant concrete, acid-resistant fiberglass or plastic. Sites with more than 5 to 7 percent slope (5 to 7 feet of elevation drop per 100 feet of horizontal distance) should generally be avoided for lagoon construction. Publications are also available from the American Water Works Association; call 303-794-7711 for more information. The appropriate regulatory agency shall approve the method of effluent disposal. If you live in one of these areas, or if you are not sure of the pollution potential from your proposed system, seek professional help with your site selection. An estimated 30 percent of all housing units in Missouri use onsite wastewater treatment systems. Typically, a new three-bedroom home is equipped with a 1,000-gallon tank. Your county health department may have resources to test your water, or to provide sample bottles for sending samples to the Missouri Department of Health. Such nutrients promote weed growth and lower oxygen levels in surface water and thus affect fishing and recreational use of rivers and lakes. Q {SEvR0!9>*wRafg~qmy$~V,Sv6&.c. If you are having accessibility or usability issues with our website, please fill out an Accessibility Issue form. A septic system depends on good soil conditions for treatment and disposal of effluent. The distribution system consists of a series of perforated plastic distribution pipes laid in the ground, usually in gravel-filled trenches. Solids accumulating in the distribution box indicate damaged baffles, inadequate septic tank pumping, or that the tank is too small to handle the wastewater load. Some of the publications available from NSFC are: Contact your county health department, MU Extension staff, or private testing laboratories. Because many of these soils are unsuitable in their natural state for lagoon construction, two methods soil morphology evaluations and percolation tests are commonly used for identifying appropriate soil modifications. 0000004260 00000 n Since soils can be quite variable even 50 to 100 feet apart, it is wise to dig several pits for evaluation of the best site. Depending on the manufacturer, seams in the liner may be hot-fused or overlapped, and the ends of the liner material may be anchored in a trench dug in the top of the berms around the perimeter of the lagoon. Bacteria in the tank begin to break down some of the sludge into simple nutrients, gas and water. The berms should be built in four- to six-inch lifts of moist soil, taking time to compact each layer of soil before adding the next. 2 22. Then the lagoon should be resealed and refilled with fresh water. On level sites, pumps must be used to remove the collected water. The older your system, the more likely that it does not meet the latest standards. Lincoln County has many reputable home builders who choose to construct a new home at or above the minimum standards established by the Residential Code. Figure 4.3Cross section of a septic system showing the septic tank and distribution system. State of Missouri Department of Natural Resources. These activities compact the soil, and soil microbes need oxygen to digest wastes. Although some choices may not correspond exactly to your situation, choose the response that best fits. 0000002208 00000 n 1989) as enacted by Senate Bill 68 . Help is available through your local Department of Health office, MU Extension center, Natural Resources Conservation Service office, or the Missouri Division of Geology and Land Survey in Rolla, Mo. THE SEPTIC TANK Provide a cleanout or manhole (Figure 4) near the lagoon berm to allow access for unclogging blockages. Another oxygen source is breezes blowing across the lagoon surface. Residential waste stabilization lagoons are commonly used for onsite sewage treatment in Missouri in low-population areas where soils are not suited for conventional absorption field systems. After this initial prefill, the lagoon will gradually be filled by the incoming effluent from the home. Homeowner's Septic Tank System Guide and Record Keeping Folder, WWBLPE30. Soil morphology evaluations are done by digging one or more 4- to 6-foot deep soil pits using a backhoe. Otherwise, raw sewage may flow directly through the tank and into the lagoon, possibly creating odors or causing solids to float on the water surface. Vertical separation from the lagoon bottom to creviced bedrock must be at least 3 feet, or a compacted clay liner or synthetic liner must be used. Construction in the red and yellow clays of the Missouri Ozarks must be done during moist soil conditions or excessive lagoon leakage is likely. Septic Systems and Wells New Permit Application Forms - . Install cleanouts (Figure 4) every 50 feet (100 feet minimum) along the pipe or wherever the pipe turns corners sharper than 45 degrees. If a garbage disposal is used in the home, a septic tank is necessary to reduce the amount of fats and solids going to the lagoon. The septic tank should be large enough to allow retention of the raw sewage for at least 48 hours.

Do divert other sources of water, such as roof drains, house footing drains, sump pump outlets, and driveway and hillside runoff away from the lagoon system. Lagoons may be used where there are no significant limitations related to groundwater and the soils are known to be impermeable. Don't run water longer than necessary; for example, turn the water off while brushing your teeth or shaving. County or city laws, however, may impose more stringent or additional requirements. A grassed area surrounding the lagoon takes up these liquids, minimizing the potential for ground or surface water pollution. In this stabilization process, bacteria release carbon dioxide that is used by the algae in their growth process. Roughen or scratch any smeared areas of the hole sides and bottoms to provide a natural soil surface for water to penetrate. Good wastewater treatment depends on good dispersal of wastewater over the drainfield. A serial distribution system is designed so that the trenches are used in sequence; when the first trench is overloaded, the wastewater overflows into the next trench down. An estimated 30 percent of all housing units in Missouri use onsite wastewater treatment systems. You can also talk to your neighbors because if they have septic systems, you likely do too. When completing the application form, you'll be required to detail the land that will In severe cases, the contents of the lagoon may need to be pumped or dredged out. Trees and high weeds should be located at least 50 feet from the water's edge. The exact locations of system components are not obvious, because they are below ground. The better the soil type or greater the amount of absorptive trenches, the higher the system's capacity for wastewater treatment. Do not allow the lagoon's compacted earthen liner to dry out. As soon as possible after construction, seed the berms with a locally hardy grass from the outside toe to 1 foot above the water line on the inside slope to minimize soil erosion and simplify weed control. Install a gate large enough (36 to 48 inches wide) to allow access for maintenance and mowing equipment. Required length of drainfield trenches is based on the amount of wastewater produced by the system and how much water a unit area of soil can treat. It also carries nutrients like nitrogen, phosphorus and organic wastes.
