As construction began and detailed transit elevations were taken, it became apparent that the two terraced beds originally designed could be combined into one large bed, double the area of each parallel bed. We approved this change, with the final overall bed being constructed to a dimension of 22 x 55 feet, or 1210 square feet, almost 200 square feet larger than the previously specified 1025 square feet. As you requested, the 4" bed supply line from the septic tank was sleeved continuously from the septic tank to the filter tank. The system is presently operational, and installed upright inspection pipes will permit monitoring of the wastewater fluid level.

During the construction of this system, Armstrong Engineering will conduct two supervisory inspections, and in addition will analyze a sample of the capillary sand to ensure proper capillary rise potential. Mr. Davis has informed me that he has paid the Garfield County Sanitation permit fee, and that the construction permit would be issued pending receipt of our engineering report.

Sincerely, Peter Armstrong Armstrong Engineering Colorado Registered Professional Engineer #17987 PRA /jc Engineered Wastewater System Davis Residence, Carbondale, Colo filed August 29,1983 Prepared By Armstrong Engineering 715 Peterson, Fort Collins, CO 80524 Contract Number WW- FCO2- 80CS30532 This report and accompanying blueprints detail the design of an evaporation- absorption wastewater treatment system for the Davis Residence, located at 0900 County Road 170, Carbondale, Colorado. A wastewater disposal bed is described which employs a combination of soil infiltration and evapotranspiration of wastewater. Special attention has been given to protection of the existing water well from contamination, and to preventing wastewater bed pores from clogging. Wastewater Flow and Pollution Load Household Characteristics: 2 Bedroom Household 1 Full Bath Dishwasher:None Water Softener: None Insulated Hot Water Pipes:Installed Low Volume Flush Toilet:Installed Water Saver Washing Machined:Planned Low Volume Shower Flow Control:Installed Lifestyle:Owner /Occupant appears committed to energy and water conservation Estimated Design Wastewater Load (design hydraulic loading ✓ rate): 100 U.S. gal per day Septic Tank Characteristics: 2 Compartment 1000 U.S. gal cast concrete Total Volume is for 4 days retention time plus 1 day equivalent for sludge and scum. Wastewater Depth: 41 inches Area Calculation for Evaporation- Seepage Bed Measured Percolation Rate in Proposed Bed Location: 125 -173 minutes per inch Carbondale Regional Evapotranspiration Rate: .24 gal /sq ft /day (Based on Pan Evaporation Rates of 33 inches per year. and average yearly rainfall of 16.5 in /yr. Referenced CLIMATOLOGICAL DATA, Colo Ann. Summaries Daily Soil Seepage Rate: .21 -.25 gal /sq ft. Active Interface Area of Seepage Bed equals Wastewater Load X Pollution Load (dimensionless)* Si Infiltration Rate + S Evapotranspiration Rate 100 x 2.3 = 511 sq ft. bed area .21 + .24 * Average Pollution Load Values Determined by Biological Ok vi'i Demand BOD and Suspended Solids SS: aeration tanks:.9 -1.2 avg. septic tanks: 1.8 -2.8 small septic tanks: 3.0- 3.8 Therefore a seepage bed area of 1022 sq feet is selected, thus providing a 100% safety factor. By soil infiltration alone this bed area will provide a wastewater absorption capacity of approximately 250 gals /day. Evaporation- Seepage Bed: Siting Existing land contours and allowable protective distances from existing water well restrict choice of seepage bed sites. A site has been selected wwhich offers minimum 100 feet well clearance, low traffic (surface compaction discouraged), and minimal slope. Existing slope in bed vicinity (11 %) will require some terracing and diversion of stormwater. Bed Construction -Two beds are to be constructed with outline dimensions of 10.25 feet x 50 feet. - Excavation of all bed area down to 14" below original ground on downslope side of bed. Part of constructed bed is above ground for good storm water diversion. -Soil Interface at bottom of bed to be Level (tolerance 1/2 ") for even distribution of wastewater. -Soil Interface to be scratched or roughed -up to open soil pores for best infiltration (no walking on it) prior to application of sand. -1" of sand to prevent inactive interface from stone shadow. -5" of gravel to act as biological filter. -4" perforated wastewater distribution pipes, sloped 1/8" per ft, interconnected at tail ends and equipped with air vents to distribute wastewater evenly and to supply air into the bed. - 3" perforated air supply pipes, connected to vents, below and above distribution pipes. -12" layer of sand in which pipes are embedded for capillary rising of wastewater and for air supply from the surface. - Crowning of the Bed and coverage with up to 2" sandy topsoil, preferably with rolled turf or sod for transpiration of wastewater and diversion of storm water. - Surface not usable for active sports, playground, patio, driveway, etc. in order not to inhibit evapotranspiration. Operation, Maintenance Very little maintenance of the bed is needed, only upkeep of planting and of storm drainage, as long as the septic tank performs as designed. In the event of bed pore clogging, the ability of the soil to infiltrate wastewater would be severly reduced. Therefore, a security filter has been added upstream from the bed supply in order to protect the bed pores. Periodic inspection (every 3 months) of the security filter and occasional replacement of the filter sand (once every two years) are recommended. In the event of septic tank failure, the filter sand would need to be replaced immediately. Periodic inspection of the septic tank (sludge depth) will help prevent septic tank failure and lessen security filter maintenance. Notification, Inspections by Engineering Firm Armstrong Engineering will perform supervisory inspections during the construction period of the evaporation- seepage bed. Inspections will be required at the date of bed excavation, and at the date all wastewater piping is in place prior to coverage. In addition, samples of the capillary sand (.5 -lmm grain) must be submitted to Armstrong Engineering and approved by same prior to coverage of wastewater distribution piping. Five working days prior notification must be given to Armstrong Engineering in advance of proposed date for inspection. Installation of the evaporation- seepage bed must conform to the blueprints and specifications supplied by Armstrong Engineering in this report.
