Box 219 Glenwood, Springs, Colorado 81602 (303) 945-7755 Denver Direct Line: 893-1608 Attached herewith is the design criteria for a wastewater treatment system for your proposed residence in Brush Creek Village. The design concept utilizes a septic tank and drainfield. The drainfield is a mound type soil absorption system that is elevated above the natural ground in a suitable fill material. This system is used because of the shallow permiable soil zone above creviced or porous bedrock. The following ar the design parameters t2� 'OF& Single famihy €mT- bedroom home Infiltration rate of natural soils 0.5 Porous or creviced bedrock less than 4 Water table greater than 4 ft. deep Design flow rate = 150 gpd per bedroom Ground slope less than 12% Septic Tank used in the system design: apd/ft2 ft, deep The septic tank shall be a concrete tank with a 1,000 gallon liquid capacity to provide a minimum of 30 hours of detention. Pre -cast tanks such as those manufactured by Copeland Concrete, Inc. in Rifle, Colorado, are acceptable. 0 Dave Elston 10/11/85 Page 2 Soil Absorption Mound NoI The soil absorption system shall be a mound type as shown on the attached Figure 7-10 and figure 7-11. The mound shall be located on natural ground, approximately parallel to the contour of the land on a slope no greater than 12%, as shown on figure 7.12. Topsoil shall be plowed or raked with backhoe teeth prior to placing the mound fill. Fill material shall be a medium textured sand, with characteristics as given in table 7-8, a copy of which is attached. Absorption bed material shall be porous media consisting of rock fill sized between 3/4"-2-1/2". Fill material and absorption bed material are available from local sand and gravel suppliers. All materials and installation practices shall comply with applicable Pitkin County standards. Mound dimensions for your system are as shown below. Refer to figure 7-13, (A) cross section and (B) plan view for location of dimensions listed: A = 10 ft. d = 50 ft . D= 1ft. E = 2 ft.(') F = 9 in. u= 1ft. H = 1-1/2 I=16ft.M* J = 7 ft.0 ) K = 12 ft. L = 74 ft. W = 33 ft.(1 NOTE: (1) Based on 10% slope will vary depending on actual slope in field. Dave Elston 10/11/85 Page 3 We suggest that the septic tank and soil absorption mound be installed by a contractor experienced in the practice of installing these systems.

The septic tank shall be equipped with a siphon dosing capability as recommended by Mr. Nelson. Pre -fabricated tanks with built-in siphons are available in 1,000 gallon capacity to meet this requirement. The absorption mound shall have four distribution laterals, 1-1/2" diameter, 28" O.C. served by a 2" diameter manifold. The manifold shall enter the absorption bed at or near the centerline of the long axis. (dimension B) The septic tank shall be within 50 feet of the absorption mound, and the outlet shall be four feet higher in elevation to provide a minimum head at the end of the distribution pipes of 2 ft. A sieve analysis shall be run on the fill material to assure that it meets the standards specified in table 7-8. We recommend that you have all phases of the tank and mound installation checked and approved by the Pitkin County Sanitarian during construction. Very truly yours, WRIGHT WATER ENGINEERS E y maul S.

Box 219 Glenwood, Springs, Colorado 81602 (303)945-7755 Deriver Direct Line: 893-1608 ursuant to Pitkin County Building Code requirements we are submitting this letter to verify the installation of the septic tank, dosing chamber and absorption mound on the Dave Elston property in Brush Creek Village. The absorption mound system was designed by Wright Water Engineers and installed by a private contractor under the supervision of Mr. Elston. Wright Water Engineers aid not observe the installation but did make a field inspection of the site on November 22, 1985 after completion of the installation. The size and location of the absorption field is as specified and the mound was covered with straw. At the time of inspection the mound was not covered with topsoil. The location of the field with respect to the septic tank and dosing chamber is in accordance with the recommendations in our letter Bated October 28, 1985. The septic tank and dosing chamber are separate precast fiberglass tanks. The 4" diameter pipe from the dosing chamber to the absorption mound is as specified. �•lound construction, bedding material and distribution laterals were covered and therefore could not be inspected.
