Septic Tank 1. The septic tank shall be State approved (Section .1953 of 15A NCAC 18A), watertight, structurally sound, and 1,000 gallons in capacity. 2. The septic tank will be fitted with an approved effluent filter and riser for easy access and periodic maintenance. 3. It is the responsibility of the septic contractor to thoroughly inspect the septic tank prior to accepting delivery to assure that the tank has had time to properly cure and is free of cracks or other structural deficiencies. B. Pump Tank 1. The pump tank shall be State approved, of one-piece construction, watertight, structurally sound and 1,000 gallons in capacity. Again, it is the responsibility of the septic tank contractor to thoroughly inspect each pump tank prior to accepting delivery. 2. All pipe penetrations into the tank shall be booted(i.e., C-293 boot with a stainless steel strap). 3. The pump tank shall have access risers that extend, at a minimum, 6 inches above finished grade and must have less than 36 inches of fill over its top once finished grade has been established (a reinforced concrete tank will be required if finished soil cover is 36 inches or greater in depth). 4. Floats,pump and control circuits,and the control panel shall meet the requirements of Rule .1952(c). Panel and control equipment shall include lightning protection, be protected from unauthorized access, and remain accessible at all times to the system operator. 5. The pump and alarm controls shall be provided with manual circuit disconnects within a watertight, corrosion resistant, Nema 4x rated control panel. The control panel must be securely mounted outside, adjacent to the pump tank riser and at a minimum of 12 inches above finished grade. Pump and float control wiring should be long enough to reach from the tank to the control panel without splicing, routed through wire conduit, and sealed at the openings within the pump tank as well as the control panel enclosure. It is paramount that the conduit is properly sealed to prevent the escape of flammable gases from the pump tank. Furthermore, there must be two electrical circuits for the pump tank controls: one for the pump and one for the alarm controls. 6. Float switch tie downs must be made of a corrosion resistant material (per OWPS, all metal in the tanks shall be stainless steel). Floats should be mounted on a separate"float tree"rather than the pump supply line (see pump tank detail). 7. The pump removal system will be via a pump tether made of nylon rope or its equivalent. The tether material should be resistant to mildew and rot. C. Pipes and Fittings 1. All discharge piping,connectors and supply lines should be made of SCH 40 PVC. 3 Lot 131-Millstone 2. All joints must be properly"welded"utilizing the appropriate PVC cement for each application. 3. The supply line will be approximately 103 feet long. D. Distribution Method—Pressure Manifold 1. A pressure manifold shall be used to distribute wastewater to five drainlines. 2. The pressure manifold shall be contained within an adequately sized box/vault that will allow future repair lines to be installed and is designed to allow for drainage of effluent that may accumulate in it during flushing and head pressure adjustments. The box should be placed upon a gravel base. 3. A gate valve shall be provided at the pressure manifold box to allow for final pressure adjustment(2 foot of head pressure as per design). 4. The pressure manifold shall be constructed of SCH 80 PVC. 5. There shall be 5 taps (1/2-inch SCH. 40 PVC -direct thread or saddle). 6. Each tap to have a true union ball valve that will allow for future removal/replacement. 7. The connecting pipe between the pressure manifold taps and the drainfield shall be constructed of PVC. E. Drainfield Installation 1. The proposed drainfield location has been marked on-site utilizing metal stemmed flags. Once this area has been approved by the county, the property owner/builder should mark this area and isolate it from construction traffic. Prior to the system installation, the septic contractor shall contact the county for a preconstruction conference at which time the drainfield area will be re-verified. 2. Under no circumstances shall any construction take place within the drainfield area while the soil is in a wet condition. If the installer has doubts as to whether the drainfield area is dry enough to begin construction, the environmental health specialist for this area should be contacted for permission to proceed with the installation. 3. The specified system is a pump-to horizontally installed pre-fabricated permeable block panel system — specifically the panel system manufactured by T&J Panel Wastewater Treatment System, Patent No. 4013559; telephone: 1-800-222-2577. The installer must follow the manufacturer's guidelines for installing the T&J Panel System and should request an installation manual from the manufacturer prior to beginning construction. 4. The initial drain field consists of five(5)lateral trenches,each being 3-feet wide by 40-feet long. 5. It is essential that the lateral trenches be constructed on contour with the land,with each trench being excavated level from beginning to end. The use of a tripod mounted engineer's level is essential to assure that each trench is constructed as level as possible. 6. The trench depth for this system shall be 19 inches. Each trench shall be placed on a minimum of 8-foot on centers. 4 Lot 131-Millstone 7. Once trenches are dug, the side walls shall be raked, and a light dusting of lime applied. 8. Backfill the trench with 7 inches of sand and level to grade. Once leveled, place 1 x 4 or 6-inch boards on top of the sand the entire length of each trench. Once the grade boards have been set,the panels may be set into the trench. The panels should be placed 6 inches apart. 9. Once the panels have been set, line the top portion of each chamber with the T&J supplied sand alternative product (SAP —geotextile fabric). GE Foam Scaler or tar seal rope should be placed in the bottom of the U outs to form seals around the pipe as shown in earlier drawings. 10. Once the GE Foam Sealer or tar seal rope is in place,a section of 2 inch PR160 pipe is cut to span from inside of the two chambers to the next two chambers of the following panel.If tar seal rope is used,it should be of tar or butyl that is soft and pliable to obtain a watertight seal. 11. Once the connection and sealing are complete,a block cap is placed on each end of the panel covering all openings. (These will be delivered with the panels.) The cap block may well serve as an inspection port at some future date.The trench is then ready to be backfilled to the top of the panel with the same backfill sand used in the trench bottom. With the sand to the top of the panel,trenches should be left for the sanitarian to inspect. Soil cover should be added after the final inspection. (At grade installation systems are required to bring in 6 inches of topsoil; suited for vegetative growth). F. Proper Operation Check 1. After all components of the wastewater disposal system have been installed and connected, the system shall be checked for proper operation. 2. With the electrical power turned off, fill the pump tank with water until the liquid rises to a level high enough to activate the high-water alarm float. Turn on the electrical power. The alarm, alarm light and pump should activate at this time. Turn off the electrical power once these checks have been performed and prepare to set the head pressure at the valve box. G. Pressure Head Adjustment 1. The pressure head must be adjusted to match the design specifications (2-Feet). The pressure head is measured by the height of the liquid coming from the pressure manifold. 2. Prepare a length of pipe (standpipe), cut to the desired head pressure height and fitted with a threaded adapter that will screw into the pressure manifold. Turn on pump and adjust the manifold gate valve within the supply manifold box to achieve the specified head pressure (liquid height in the standpipe should equal the design head pressure). 3. Once the pressure head has been adjusted, allow the pump to run through the remainder of the cycle. The pump float switch will automatically turn the pump off if it is operating properly. Make sure that the effluent pump is completely submerged in the remaining water, adjusting the float switch(es) as needed. This completes the checks for proper operation of the pump, alarm, and float switches. 5 • Lot 131-Millstone 4. At this point,the manifold standpipe may be removed and replaced with a threaded plug. H. Final Landscaping 1. Final cover over the drain field shall be at least 6 inches deep (additional soil cover may be required to achieve the 6-inch requirement). 2. The drainfield shall be shaped to shed rainwater and be free from low spots. 3. The drainfield area should be planted with grass as soon as possible to prevent erosion. The soil should be properly tilled, limed (if necessary)and fertilized prior to planting. After applying grass seed, the area should be heavily mulched with straw or other suitable material. I. Utility Conflicts 1. The builder and property owner must take special care in planning for water,power, gas, telephone, and cable lines. These utilities shall be kept clear of all parts of the septic system and its proposed repair area. Improper planning for underground utilities can negatively impact the installation and, in some cases, cause irreparable damage and permit revocation. If there are any questions regarding preferred routes, contact the LSS as soon as possible. 2. Lawn irrigation should not be placed over the drainfield area. Maintenance J. In General 1. The homeowner must maintain the drainfield area through periodic mowing. The drainfield must not be allowed to become overgrown. 2. The septic tank should be pumped every 4 years or when the solids within the septic tank reach an elevation that is equivalent to 25 percent of the volume of the tank. In some situations, the tanks may need to be pumped more frequently. If using a garbage disposal, it is recommended that the homeowner has the septic and pump tanks cleaned out annually. 3. When it becomes necessary to clean the effluent filter, the filter should be removed, and the accumulated debris washed back into the septic tank—not onto the lawn. 4. Any damp areas, leakages or malfunctions in the drainfield area should be addressed immediately. 5. Divert gutter downspouts and surface water runoff away from the septic and pump tanks. 6 Lot 131 -Millstone Design Specifics Daily Design Flow: 360 GPD—3 bedroom house Septic Tank Size: 1,000 Gallons(minimum) Pump Tank Size: 1,000 Gallons(minimum) Pump Requirements: 35.55 GPM at 21.5 Feet TDH Recommended Pump: Liberty FL50 or equiv.
