P 9 President PJV:fo Enclosures SOLAR PLAZA P.O. BOX 131 GRANBY, COLORADO 80446 (303) 887-2303 INTRODUCTION The purpose of this report is to determine the best practical method for the disposal of wastewater on the parcel of land owned by the Musket Corporation. This particular piece of ground under investigation is in a portion of the SEa of Section 3, T2N, R69W of the 6th P.M. , Weld County, Colorado and con- sists of approximately five acres. (See Vicinity Map) It is proposed that the wastewater facilities will serve a truck stop with a fast foods restaurant, which will be called Love' s Country Store. The truck stop will employ 20 people. Food service will consist basically of sandwiches , using disposable utensils. The estimated vehicular traffic, over a 24-hour period, is estimated to be 1500 cars and 300 trucks. (See Site Plan) FIELD INVESTIGATION Field investigation consisted of three percolation borings to a depth of approximately 36 inches; a percolation test; a soil boring to a depth of eight and one-half feet; a routine soils analysis; and a brief site survey to locate physical features. SITE INFORMATION The site slopes to the north and away from Highway 119 at an approximate grade of 2 to 3 percent. On the south end of the lot is located an old house and barn along with a few large trees. The remainder of the lot is covered with weeds, grass and debris. The north and west sides of the lot have a marshy appearance. On the east and west adjacent lots is a liquor store and a large motel , respectively. Both of these facilities have their own water supply and waste- water treatment facilities. While the liquor store has a simple septic tank and leach field, the motel (Best Western Centennial Inn) has a sizeab}e activated sludge process followed by two stabilization ponds. The motel has a man on duty to perform operations and maintenance of the facility. Across Highway 119, and approximately 400-feet to the south, are the wastewater treatment facilities for the Del Camino Village Park. These facilities consist of an activated sludge process. The Del Camino Village Park also has a man on duty to perform operations and maintenance of the facility. Also serving the Del Camino area with water service is the Lefthand Water District. Discussions have been held with all agencies (Best Western, Village Park, and Lefthand) about water and sewer service. PERCOLATION STUDY A total of three percolation tests were run on the site. It was extremely difficult to maintain a measurable water level in each test hole during the four hour test period because of the rapid percolation rate. The final 30 minute interval of the percolation tests indicate an average rate of approximately 4.5 minutes per inch. SUBSURFACE SOILS CONDITIONS The soil at the location where on-site wastewater disposal facilities may be installed is basically a clayey sand over a silty, gravelly sand. Ground water was encountered 2.3 feet below the surface. No bedrock was found. Soil samples were also collected at the proposed building site for the purpose of foundation design and these correlated closely with the collected samples for this study. (See Soil Boring) WATER USAGE AND WASTEWATER GENERATION RATES The guidelines published by the Colorado Department of Health concerning individual sewage disposal systems , and the "Manual of Septic Tank Practice" published by the U. S. Public Health Service were used in part, to estimate water usage and wastewater generation rates. These two publications provide water rates for average conditions for various types of business and recrea- tional establishments. However, some interpretation of these published rates is necessary as they generally do not exactly apply to the case at hand, and the subject situation is no exception. The subject situation is as follows: A truck stop or service station ---which employs 20 persons. ---where the daily vehicular loading is expected to be 1500 cars and 300 trucks. ---where restrooms will be available to its patrons. (3-toilets , 1-urinal , 2-sinks) ---which will also have a fast foods restaurant with disposable utensils. It is assumed that 25% of the patrons stopping will use the restaurant facilities. On this basis and using the previously mentioned guidelines , the possible range for water usage and wastewater generation was estimated. Colo. Dept. of Health U.S. Public Health Svc. 20 Employees Factories and Plants 20 x 35 gal/employee = 700 gpd Restaurant 1500 cars and 300 trucks = 3300 patrons. 3300 x .25 = 825 meals Food Service Establishments with paper service 825 x 1 .5 gal/meal = 1240 1240 gpd Service Stations 1800 vehicles x 10 gal/veh. = 18,000 gpd Restrooms (Oper. 24 hrs/day) Toilets 3 fixtures x 36. gal/hr x 24/hrs= 2592 Colo. Dept. c Health U.S. Health Service Urinal 1 fixture x 10 gal/hr x 24/hrs = 240 Sinks 2 fixtures x 15 gal/hr x 24/hrs = 720 5 ,492 gpd 19,240 gpd TOTAL The Musket Corporation operates a similiar truck stop in Texas, and water usage for the first month of its operation was 67,000 gallons , or 2,250 gallons per day. In consideration of this data and the estimated rates , the recommended average daily water usage and wastewater generation is 5,500 gallons. Maximum flow conditions is considered to be 150% of this average flow or 8,250 gallons per day. This maximum flow is to be used in the design of the facilities. POSSIBLE ALTERNATIVES Based on preliminary discussions with adjacent property and utility owners , and our knowledge of the area, three possible wastewater alternatives exist. These are: 1 . On-site treatment and disposal (septic tank with leach field) . 2. Connection to the Del Camino Village Wastewater Treatment Facilities. 3. Connection to the Best Western Centennial Inn Wastewater Treatment Faci- lities. The approximate cost of each of these alternatives is as follows : 1 . On-site ---Construction Cost $20,000 ---0 & M Cost $ 500/yr 2. Del Camino WWT ---Tap Fee $17,000 ---Construction Cost (sewer) $14,000 ---Service Charge $ 6,000/yr 3. Best Western WWT ---Tap Fee $12,000 ---Construction Cost (sewer) $ 8,000 ---Service Charge $ 1 ,200/yr The construction and 0 & M costs are estimated. The tap fee and monthly service charges are, of course , open to negotiation. However, these fees and charges were indicated in our preliminary discussions with these parties. CONCLUSIONS AND RECOMMENDATIONS The most economical solution to the treatment and disposal of wastewaters from Love' s Country Store is with on-site facilities. These facilities are to con- sist of a conventional septic tank(s) followed by a seepage bed, with some modifications. These modifications are necessary to compensate for the fast percolation rate and the high ground water table. Since the percolation rate was faster than the allowable minimum of 5-minutes per inch, it will be necessary to make the soil below the field less porous. Since it is required to maintain 4-feet of soil from the bottom of a seepage bed to the ground water table, it will also be necessary to elevate the seep- age bed at least 2-feet above the existing grade. Therefore, it is recommend- ed that the approximate area of the seepage bed, 90-feet square, be covered with 3-feet of the clayey sand removed from another part of the lot and light- ly compacted. For the proper design of the seepage bed, additional percola- tion tests in the compacted fill will have to be performed. The measured percolation rate at that time, will determine the required seepage bed size, using the formula: an A = Q 5 where A = area of field Q = maximum flow t = percolation rate Since the maximum flow was previously determined to be 8,250 gallons per day, the formula reduces to: A = 8250 5 or 1650411 A graph of this formula is attached for convenience in sizing the seepage bed. (It is shown as the solid line on the graph) . Because elevation of the seep- age bed above the existing grade is necessary, and because the flatness of the property, it will be required to pump the septic tank effluent to the seepage bed. To achieve proper distribution of the effluent on the bed, the pumping cycle should be sufficient to flood the entire area of the bed to a depth of one-half inch. To insure this , the volume of the pumping station, between high and low water levels, should be equivalent to this volume. In other words , with a seepage bed area of 5,218 square feet, the operating volume of the pump- ing station should be 1 ,561 gallons. This can be expressed by the following formula: V = A(7.48)(0.04) or 0.3A where V = operating volume A = area of seepage bed A graph of this formula is also attached and is indicated as a dashed line. In sizing of the septic tank(s) , a 30-hour retention period is considered mini- mum. Therefore, the septic tank capacity should be: 8,250 gallons/day x 30/hours = 10,313 gallons 24 hrs/day Septic tanks are generally manufactured in 500 and 1000 gallon increments , however, it is recommended for this installation , that either 2-6,000 gallon septic tanks be installed in series , or 4-3,000 gallon septic tanks be in- stalled in a parallel series as shown on the Proposed Site Plan. In conclusion, all exterior area drains are not to be connected to the treat- ment and disposal system. All sewers serving the kitchen facilities shall be equipped with a grease trap. All construction should be in strict conformance with applicable federal , state and local specifications. During construction and prior to backfilling of the facilities, the owner and/or contractor shall notify Western Technical Services , Inc. for an inspection of these facilities.

The distance from the outlet invert to the underside of the top of the tank shall be at least 10 inches. The first compartment of a two com- partment tank shall hold one-half to two-thirds of the effective capacity of the tank. All septic tank manholes and/or inspection ports shall extend to within eight inches below finished surface grade. At least one access, no less than 20 inches across, shall be provided for each compartment. Backfilling around the septic tank shall be accomplished in a manner to prevent tank settlement and to avoid undue strain on the tank and the pipes entering the tank. D. Pumping facilities - The pumping facilities shall be adequately and durably constructed and watertight. The facilities shall be -constructed so that access to the pumping unit is convenient and safe. The pumping unit shall consist of a duplex "sump-pump-type-unit" with a capacity of pumping 15 gallons per minute at a total dynamic head of 20 feet. The force main from the pumping unit to the seepage bed shall be 11/4 to 1' inches in diameter, plastic pipe, designed for pressure flows. This force main shall be in- stalled at a depth to protect it from freezing. The line shall also drain back toward the pumping facilities when the pumping unit is not in operation. It shall not be installed with any low points in the system which may trap water. The contractor shall concern himself particularly with protecting the pipe from freezing. The contractor is to refer to the drawing entitled "Miscellaneous Schematic Details" included with this report for the install- ation of the pump, septic tank and seepage bed. E. Seepage bed - The bottom of the bed and distribution pipe shall be level . A 15-inch thick layer of one-half to two and one-half inch washed gravel shall be spread over the entire bed, with the pipeline set at a depth to insure at least eight inches of gravel below and two inches of gravel above each line. A covering of untreated building paper, straw or similar materials shall be placed on top of the gravel and backfill shall be placed over the bed to a minimum depth of 12-inches. The ground surface around the bed and the finished surface over the bed shall be graded to deflect precipitation and other outside water from the disposal field. The field lateral lines for distribution of the wastewater throughout the seepage bed shall be either open joint sewer pipe or perforated pipe. If open joint sewer pipe is used, the upper half of the joint opening, which should be approximately 1/8 to 1/4 inch, should be covered. Field lateral lines shall be spaced not greater than six feet apart. Backfill covering the seepage bed shall be sloped at a grade not more than three to one (3 hori- zontal to 1 vertical ) to the existing grade. Four inch vent lines shall be installed at each corner of the seepage bed. The vent line shall ex- tend twelve inches above the ground. The existing ground surface over which the seepage bed is to be placed should be cleared of all organic matter and the exposed surface scarified before placing the fill material . (See Miscellaneous Schematic Details included in this report. ) The topsoil to be used in the construction of the bed shall be that material found in the area but shall not be excessively granular so to provide the proper filter- ing action of the wastewater. F. Inspection - After the wastewater disposal system has been installed and before it is used, the entire system is to be tested and inspected. The septic tank is to be filled with water and allowed to stand overnight to check for leaks. If leaks occur, they are to be repaired. The soil absorption system should be inspected before it is covered to be sure the disposal system is installed properly. All backfills are to be free of large stones and other deleterious material . **************************************************************************** PLEASE NOTE This system is designed only for usage as described in this report and based on conditions found at the time of the investigation. For proper and con- tinual successful operation of the system, the owner is encourged to follow the guidelines on the care and cleaning of the septic tank indicated on Pages 35 through 39 of the Manual of Septic Tank Practice, USPHS Publication 526. Briefly, these major guidelines point out the need to inspect the septic tank at least once a year and have it cleaned when necessary. In addition, the septic tank should not be washed or disinfected after pumping and a small residual amount of sludge should be left in the tank for seeding purposes.

O. Box 26210 Oklahoma City, Oklahoma 73126 (405) 751-9000 DATE : JULY 30, 1982 PROJECT NO: 82-428-01 PREPARED BY: Western Technical Services, Inc . 1024 8th Street Greeley, Colorado 80631 (303) 352-5780 NE(I COUNTY CNMSS{ IS d C I J AUG 4 1982 QRggzni cou% 1024 EIGHTH STREET GREELEY, COLORADO 80631 13031 352 -5780 OPERATION OF PROPOSED SYSTEMS The proposed treatment system will operate in the same efficient manner as any septic tank and percolation field system functions, which is properly designed and maintained. The system, as indicated in the submitted report , is located so that all minimum horizontal distances between the components of the wastewater disposal system and pertinent ground features , as specified by the Colorado Department of Health, are satis- fied. Actually the one horizontal distance of major importance is that distance to the Centennial Inn ' s well, (the property immediately to the west ) . This distance is far in excess of the 100 foot minimum and is approximately 200 feet . The only other distance of concern is that distance from the bottom of seepage bed to the ground water level in the area. Since this required distance is 4 feet , the seepage bed was raised above the existing ground level , due to the high ground water level , to achieve this distance . The fill material (the eventual soil which will filter and further treat the wastewater) will be selected and compacted to achieve the recommended range for percolation. This range according to State Health Department Standards is 5 to 60 minutes per inch. The measured percol- ation rate of the existing soil just boarders on this range at 4. 5 minutes per inch. The basis of these standards is to pro- tect the ground water from pollution and the development of any health hazards. The design, as submitted, will comply with these standards. Two known research publications which address this matter of the efficiency of a septic tank and percolation field system are : "Treatment Efficiency of a Septic Tile System" , T. Veraraghavan and R. G. Warnock, Proceedings of the National Home Sewage Disposal Symposium - 1974, American Society of Agricultural Engineers. "Treatment and Disposal of Wastewater from Homes by Soil Infiltration and Evapo-transpirations" , University of Toronto Press , 1973 , Second Edition. In the first publication (p. 56 ) , it is reported that 75 to 90% of the BOD present in a septic tank effluent is removed after passing through 4 feet of soil beneath a percolation field. Inthe second publication (p . 39 ) , it is reported that 45 to 62% of the BOD present in a septic tank effluent is removed after passing through 1 foot of soil beneath a percolation field . Considering that approximately 30% of the BOD is removed in the septic tank , the efficiency of a septic tank and percolation field system, 4 feet below the field, would be 83 to 93% in removal of BOD. This level of efficiency is equivalent to modern day treatment systems. When one considers the further treatment the process effluent receives as it travels through the ground, no pollution or health hazard should result from this operation. It should also be noted that even higher reductions were reported in suspended solids and ammonia. Because the seepage bed (percolation field) is elevated above the ground surface, it will be necessary to pump the septic tank effluent to the seepage bed. This pumping will assist in ensuring proper distribution of the setpic tank effluent over the entire seepage bed area. Duplicate pumps will be installed to furnish back-up facilities. The simplicity of the system requires little maintenance. Periodic inspection of the pumps to ensure their operation , and annual inspection of the septic tanks to determine the scheduling of a sanitary sludge hauler . AVAILABILITY OF EXISTING TREATMENT SYSTEMS As discussed in the submitted report , two sewage treatment plants exist in the immediate area. The first , which serves the Del Camino Village Trailer Park, is located south of the subject property and south of Highway 119 . From information obtained from the owner and operator, the plant has a capacity of 100, 000 gallons per day and is operating at 70% of this capacity. This treatment facility consists of an extended aeration process with its ultimate dischage to an irrigation ditch. No data was obtained on the age of the facil- ity, but from its appearance, it is estimated to be approximately 10 years old. An inspection of the facility indicated that it was reasonably maintained and operated. The second treatment plant in the area, which serves the Best Western Centennial Inn , is located to the west of the subject property. Since the Inn has changed ownership several times over the past years , the owner had no knowledge of the capa- city of the system. After some research it was found that this system was initially designed to treat 13 , 000 gallons per day. The maximum present loading on the facility is estimated to be 11 , 000 gallons per day . Since its design in 1972 , apparently , several modifications have been made and its pre- sent capacity is unknown . This facility also incorporates the extended aeration process , and is followed by one-aerated pond and one-evaporation percolation pond. An inspection of this facility indicated that it receives little maintenance but seemed to be operating satisfactorily . ECONOMIC CONSIDERATIONS The economic considerations were generally stated in the submitted report . To summerize them for your consideration , the following information is submitted : On Site Treatment (Septic Tank and Percolation Field) Estimated Construction Cost $20 , 000 Estimated Operations & Maintenance Cost $500/year Connection to Del Camino Village Facilities Estimated Construction Cost $14 , 000 Estimated Service Charge $6 , 000/year Estimated Tap Fee $17, 000 Connection to Centennial Inn Facilities Estimated Construction Cost $8, 000 Estimated Service Charge $1 , 200/year Estimated Tap Fee $12 , 000 If one considers the initial cost to be the construction cost plus any tap fee, then connection to the Del Camino Facilities is the most expensive at $31 , 000. The On Site Treatment and connection to Centennial are of equal initial cost ($20, 000) . On the basis of on-going costs , again, connection to the Del Camino facilities is the most expensive. Over a 10 year period, this cost would be $60 , 000. Connection to the Centennail Inn faciliites is the next least expensive, at $12, 000 over a 10 year period. Finally, On Site Treatment being the least expensive at $5 , 000. 00. It is on this basis, that the On Site Treatment is recommended and for which your approval is requested. B.
