Plain Policy No: 2001-02 Revision No: 1 Goal No: Date: January 3, 2001 Effective Date: January 3, 2001 Program: Septic Purpose: Describe the requirements to install a septic system within a flood plain, Responsibility: Office Technicians, Environmental Specialists, Supervisors, Director Definitions: Floodplain: an area adjacent to a stream which is subject to flooding as the result of the occurrence of a one hundred (100) year flood, and is so adverse to past, current or foreseeable construction or land use as to constitute a significant hazard to public or environmental health and safety or to property or Is designated by the Federal Emergency Management Agency (FEMA) or National Flood Insurance Program (NFIP). In the absence of FEMAJNFIP maps, a Colorado Registered Professional Engineer shall certify the flood plain elevations. (Source: Colorado Department of Public Health and Environment I.S.D.S. Guidelines, Revised 1994) Floodway: that area of the floodplain in which the channel of the watercourse and those portions of the adjoining floodplain which must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one (1) foot at any point or as designated by.the Federal Emergency Management Agency or National Flood Insurance Program. In the absence of FEMAINFIP maps, a Colorado Registered Professional Engineer shall certify the flood way elevation and location. (Source: Colorado Department of Public Health and Environment I.S.D.S. Guidelines, Revised 1994) . Policy: Septic systems will not be allowed to be located in the floodway per Colorado Department of Public Health and Environment I.S.D.S. Guidelines, Revised 1994. Septic systems will be allowed in the flood plain, but the system must be installed in a manner as to prevent the infiltration of groundwater into the septic tank and to prevent the release of sewage from the tank during a flood event If the tank IId is above the flood plain elevation; no special installation requirements would be necessary. If the tank lid is not above the flood plain elevation then the access to the tank manhole lids must be covered with 20 mil PVC and sealed with plumbers cement When the seal is broken, i.e. the tank is opened for pumping, etc., the tank must be re -sealed prior to backfilling again. A backflow preventer or one-way valve, must also be installed in the effluent line between the tank and the absorption field. All other percolation and suitable soil criteria must be met for a conventional septic system to be installed. For inspection purposes, the materials to seat the manhole lids must be on site. The manholes are not required to be sealed at the time of inspection in order to allow for the inspection of tee's in the tank.

EXISTING CONDITIONS/PROPOSED CONSTRUCTION The site for the proposed septic, field is located north of the area proposed for the new residence. The ground surface is relatively flat with an overall slope of less than 2%. The plan is to construct a new septic. field that will accommodate the proposed new 3 -bedroom residence._ If the plans are different, we should be notified so that our recommendations can be reviewed and revised if necessary. SOILS CONDITIONS The test pit revealed approximately 1 foot of topsoil (dark brawn, silty and sandy clay to clay silt' and sand) underlain moist, relatively soft, light brown to tan, slightly clayey silt and sand. These materials continued to depths of 6 feet, where sand and gravel was encountered. This continued to the full depth of the test pit of approximately 8 feet. GROUNDWATER Groundwater was noted during the investigation, at a depth of approxim feet, with signs of a seasonal groundwater table at approximatel Therefore; groundwater will be a design consideration. PERCOLATION TESTS Six percolation tests were prepared in conjunction with this design. These tests were intended to ascertain the percolation rate . ` - . atural soils. The, testing showed the perc rate to average approximatel 2 m /inch. The tests were performed in the area delineated on our design • - wings as the, suggested location for the absorption field. The locations of the percolation tests are shown on the site plan, included with this report: 1 1 1 i 1 1 1 1 1 1 1 WATER SUPPLY The water for the residence -will be supplied b sited or drilled. However, it will be located at a dista from the area of the new septic field. DESIGN OF THE PROPOSED SYSTEM ich has not yet been greater than 100 feet Details of the proposed system, including a site plan and a typical section of the proposed sewage disposal facility, are shown elsewhere in this report. The design of the sewage disposal system is based on criteria established by the Weld County Health Department Individual Sewage Disposal Regulations. The proposed design provides for absorption beds utilizing the onsite soils. The system design is based on the. following assumptions: • 1. Three bedrooms 2 persons per bedroom 2. Average daily flow 3. Maximum daily flow (includes grinder/washer) 4. Design perc rate The required surface area of the absorption bed 6 persons 75 gal/person/day 1.5 x average daily flow 1.5x75x6 lions/day 22 minutes/inch 1r_*,675 * SQRT(23) /3.5 1203 square feet For this system, we suggest the use of a single -field system. A bed dimension of 24 feet by 51 feet is recommended (for a total area of 1224 square feet). Design drawings of the septic system are included later in the report. OTHER DESIGN CONSIDERATIONS A two -compartment septic tank with a total volume of 1000 gallons is required for a -bedroom residence. A larger tank may be installed if desired. 3 The Weld County Health Department regulations require a minimum offset of 4 feet between the distribution layer (the bottom of the gravel layer) and the seasonal high groundwater table. Therefore, with the subjective seasonal high Page 2 groundwater table at a depth of 4 feet, the base of the gravel distribution layer will be at the existing ground surface. The residence is to be elevated significantly above the existing ground surface and, although the septic field is to be raised slightly, it appears that the residence may be served by gravity. If this is not possible then a 300 -gallon tank, in serial after the main septic tank, could serve as a lift station. Attached to this report is a drawing that illustrates our recommendations for the lift station construction, if necessary. The topsoil and any clayey soils are not considered to be appropriate materi on which to found the septic field. We recommend that the excavation for the field penetrate the topsoil and any clayey soils to the very slightly clayey silt and sand. The field excavation can. then be backfilled back to the required elevation with silty sand fill. The gravel distribution layer should theri-be constructed atop this silty sand fill. Please note that a berm will be required. Prior to placement of the fill for the berms, all organic topsoil should be removed from this area. All' fill placed for construction of the berms should be placed in loose lifts not to exceed 9 inches and should be compacted to 95 percent of maximum dry density. A 3 -foot minimum horizontal berm must be maintained along all portions of the gravel layer, which are above the original ground surface. A .10 -mil, PVC liner should also be installed along the sides of the gravel layer which are above the original ground surface. The liner should extend from 6 inches above the top of the gravel layer to at least 12 inches below the original ground surface. We understand that the area proposed for the new septic field is within the 100 year flood plain. Weld County Health Department regulations allow for a field to be constructed in the flood plain. All pertinent regulations with regard to such construction shall be -adhered to. We recommend that the field area be covered with a minimum of 4 inches of silty topsoil and seeded with a native pasture seed mix. Special attention is required to assure that the proper backfill and site grading is completed. These items are extremely important to assure satisfactory long-term performance of the field. ctfrox Page 3 SPECIFICATIONS FOR INDIVIDUAL SEWAGE DISPOSAL SYSTEM - ABSORPTION TYPE CODES AND REGULATIONS The minimum standards required herein shall not be construed as removing the necessity for compliance with any regulations established by the building and health authority having jurisdiction when such regulations provide for higher standards than contained herein. Where these Drawings and Specifications are more restrictive than local- codes and regulations, the Drawings and Specifications shall be followed. Notes on the drawings and/or requirements of the design section of the report shall take precedence over the standard Drawings and Specifications. CHANGES IN OR DEVIATIONS FROM DRAWINGS AND . SPECIFICATIONS Changes in the Drawings and specifications may be permitted according to the following provisions: 1. The change does not violate any code or regulations. 2. The request for a change is submitted to the Owner or authorized representative of the Owner prior to construction. -3. The change is approved by the Owner or his authorized representative. 4. The change is approved in writing by the .Engineer and an authorized representative of the Health Department. MATERIALS Materials used in the construction of the septic tank and absorption fields shall be durable, new, sound, and not subject to corrosion. Gravity pipe and septic field pipe shall be 4 -inch, minimum, unless otherwise indicated. PIPING The building sewer leading to the septic tank shall be laid with a minimum fall of 1/8 -inch per foot and preferably 1 /4 -inch per foot. Bends should be limited to 45 -degree "L's" or long sweep quarter bends. Sewer pipe shall be gasketed PVC gravity sewer pipe ASTM D3034 (SDR-35) or solvent weld PVC ASTM 2724 (SDR-35). Page 4 The septic field piping shall be perforated PVC ASTM 2927, or white rubber sewer and drain pipe, Spec. CS -228-61 or Fed. Spec: WWP 00380 having 1000 pound crushing strength. Between each trench or bed in the case of a serial -type system, or at distribution pipe bends, standard pipe fittings which will form rigid watertight joints shall be used. Pipe in beds and trenches shall be installed level. The terminal ends of all lines shall be capped unless looped or air vented. At least one capped inspection pipe shall be provided in each trench or section of the bed. If small diameter pump line plastic pipe is required, it shall be polyethylene plastic pipe (Commercial Standard CS 255-63). When plastic pump lines are used, no splices or fittings should be installed in the line except at its connection to the pump. All pipe, pipe fittings, and pipe joints shall be in accordance with the Uniform Plumbing code, and the manufacturer's recommendations. ABSORPTION FIELD The absorption field shall be constructed in accordance with the' lines, grades, and details given on the drawings. There shall be undisturbed earth or compacted fills retaining all septic tank effluent. All fills or dikes are subject to inspection'and approval by.the design engineer. Open trenches shall be protected from surface runoff to prevent the entrance of silt and debris. All smeared or compacted surfaces of the trench or bed shall be raked to expose the natural texture of the soil. All loose material shall be removed from the trench before the gravel is placed. Over -compaction of the field by vehicular traffic or other means shall be prevented. Gravel for the septic fields shall be washed gravel; minimum size shall be 1/2 - inch and maximum size shall be 2-1/2 inches. _ BACKFILLING AND SITE GRADING All major grading shall be accomplished before construction of the sewage disposal system is begun. Backfill around the septic tank shall be with moist soil hand tamped sufficiently to prevent future settlement. Positive drainage from and around the bed must be provided, by sloping, mounding, ditching and berming as shown on the drawings. Page 5 MAINTENANCE AND OPERATION CLEANING Septic tanks should be cleaned before too much sludge or scum is allowed to accumulate. If either the sludge or scum approaches too closely to the bottom of the outlet baffle, or other device, particles will be scoured into the disposal field and will clog the system. Eventually, when this happens, liquid may break through to the ground surface and/or the sewage may back up in the plumbing fixtures. When a disposal field is clogged.in this manner it is not only necessary to clean the tank but it also may be necessary to construct a new disposal field. Tanks should be inspected at least once a year and cleaned when necessary. Cleaning may be necessary every two to five years. Although it is difficult for most persons, -actual inspection of sludge and scum accumulations is the only way to 'determine definitely when a• given tank needs to be pumped. When a tank is inspected, the depth of sludge and scum should be measured in both compartments. The_tank should be cleaned if either (a) the bottom of the scum mat is within approximately 4 inches of the bottom of the outlet baffle, or (b) sludge comes within 8 inches of the bottom of the outlet baffle. Scum may be measured with a pole to which a flat board has been attached, or with any device that can be used to feel out the bottom of the scum mat. The pole is forced through the mat; then turned and raised until resistance from the bottom of the scum is felt. With the same tool, the distance to the bottom of the outlet baffle can be found. There are firms which conduct a business of cleaning septic tanks. The yellow pages may be consulted to obtain this service. Cleaning is accomplished by pumping the contents of the tank into a tank truck. Tanks should not be washed or disinfected after pumping. A small residual of sludge should be left in the tank for seeding purposes. When a large septic tank is being cleaned, care should be taken not to enter the tank until it has been thoroughly ventilated and gases have _been removed to prevent explosion hazards or asphyxiation of the workers. CHEMICALS In general, the addition of chemicals to a septic tank is not recommended. The functional operation of septic tanks is not improved by the addition of - disinfectants or other chemicals. Some -1,200 products, many containing enzymes, have been placed on the market' for use in septic tanks, and extravagant claims have been made for some of them. As far as is known, however; few have proved of advantage In properly controlled tests. Frequently, however, the harmful effects of ordinary household chemicals are over -emphasized.' Soaps, detergents, bleaches, drain cleaners or other material, Page 6 as normally used, will not have appreciably adverse effects on the system. However, as both the soil and essential organisms might be susceptible to large doses of chemicals and disinfectants, moderation should be the rule. Waste brines from household water -softener units have no adverse effect on the action of the septic tank, but may cause a slight shortening of the life of a disposal field installed in a structured clay -type soil. MISCELLANEOUS Roof drains, foundation drains, and drainage form other sources producing large intermittent or constant volumes of dear water should not be piped into the septic tank or disposal field. Such large volumes of water will stir up the contents of the tank and carry some of the solids into the outlet line; the disposal system following the tank will likewise become flooded or clogged and may fail. Drainage from garage floors or other sources of oily waste should also be excluded from the tank. Disposal fields of either the absorption or evapotranspiration type must not be used for driveways or parking, or any use which might overcompact the area. Drawings and designs showing the location and other information regarding the septic tank and disposal system should be retained by the property owner.
