COM Analysis of Existing Onsite Wastewater Treatment System Design 6 -bedroom residence 6191 CR 233 Garfield County, Colorado Pam, Project No. C1518 CBO Inc. performed an analysis of the existing onsite wastewater treatment system (OWTS) serving the subject residence. The 10 -acre property is located outside of Silt, in an area where OWTSs and wells are necessary. Legal Description: Section: 35 Township: 5 Range: 92 SESWSE, ANTLERS ORCHARD TR 62 Parcel ID: 2127-354-00-053 SITE CONDITIONS A 6 -bedroom, single-family residence presently exists. The original system was documented under Garfield County Individual Sewage Disposal System (ISDS) Permit 2414. The application indicated the system was to serve a 3 -bedroom residence. The installation included a 1500 -gallon septic tank and 38 `Standard' Infiltrator® chambers. The permit received final approval on April 13, 1995. An additional permit was obtained from Garfield County in 2014. There were issues with the existing soil treatment area and a new OWTS was designed by Colorado River Engineers. Garfield County ISDS Permit SETP-7-14-3299 documents this system. The permit was issued on July 9, 2014. The application and as -built are enclosed. The application indicated the house had 6 -bedrooms. The design (documented by the as -built drawing) indicates the system consists of the existing 1500 -gallon septic tank, a new AK Industries pump vault with a Goulds PE51 P1 Pump, approximately 400 -feet of 1 — 1 1/2" HDPE pipe to a distribution box and a new soil treatment area (STA) consisting of 84 `Quick 4' chambers (4 rows of 21 chambers). SITE VISIT We visited the property on April 10, 2020 with Altitude Septic. Altitude Septic had already located and gained access to the distribution box. The 1500 -gallon septic tank appeared over -full; however, the outlet pipe is cocked downward indicating settling of the pipe outside of the septic tank causing the tank to slightly over -fill in order for effluent to exit the septic tank. An effluent filter was present but was very small and prone to clogging. The pump chamber has a badly deteriorated lid. The pump sits on a block and the float tree was not connected to anything, with the off float sitting on the block. With no ability for this float to go down, the pump stayed on. The owner has reported replacing the pump several times in recent years. Page 2 The pump chamber is not adequate size for the dose needed to travel over 400 -feet to the STA. Additionally, there is no control panel for the pumping system. There is an audible and visible alarm, but no panel for manual operation of the pump or separate circuits for the pump and alarm. We walked the approximate pump line and found the topography to change (rising, dipping, and rising again) before the distribution box. The pump line must maintain a constant upward slope (min. 1%) in order to not hold water in the pump line. The distribution box was badly deteriorated and oddly configured with SDR -35 pipe functioning as baffles of sorts. The distribution box was at least 3 -feet below grade, which means the trenches are at least that deep, with the grade rising to the south toward Silt Mesa Road. We believe these trenches are likely in excess of 4 -feet deep. We ran water into the pump chamber with the pump ON and a garden hose filled the chamber in less than 10-mintues with the pump running. This is an indication that the pump cannot keep up with flow into the chamber. We turned the pump OFF. After resting, we turned the pump back ON and tracked the time it took for effluent to reach the distribution box. Time between turning the pump ON and reaching the distribution box was 5 seconds. This indicates there is standing water in the pump line that never drains back. Garfield County adopted OWTS Regulations in May of 2014 (enclosed). This design was submitted to Garfield County in July of 2014 and should have complied with minimum standards of the OWTS Regulation. Design deficiencies noted at the time of our site visit included the following: • The septic tank capacity was inadequate to serve the 6 -bedroom residence. • The pump chamber was inadequate size for the dose necessary to reach the STA. • There was no control panel with manual operation and separate circuits for pump and alarm. • The float tree was not properly affixed for proper operation of floats. • A low -head pump was installed. This design would more appropriately be served by a high -head pump. • Electrical installed in riser, not in external splice box, as required. • No access to distribution box from grade. • Depth of trenches exceeded the maximum allowed 4 -feet (likely, not confirmed). Understanding the regulatory and functional deficiencies of the system, there are options for resolving the issues: OPTION 1: Repair the existing OWTS The existing septic tank may remain. • Add risers to bring access to grade. • Replace existing filter with full size Orenco® Effluent filter and realign pipe existing the septic tank. • Remove existing pump chamber and replace with 500 -gallon, single -compartment pump vault. • Install Orenco® ProPak Pumping system and PF3005 pump (based on 400 feet of pump line, 1.25" diameter, and 15 feet of elevation gain). • We recommend pump line is explored to assure proper slope. We believe this line may change elevations causing effluent to stay in pipe, which causes the potential for freezing. This line may need to be re -installed with property min. 1% drain back. • Replace distribution box with a larger, poly distribution box with flow equalizers. (These recommendations are a summary of repairs and do not constitute a design). Page 3 OPTION 2: Replace the existing OWTS • Abandon existing septic tanks and STA. • Install new, 2000 -gallon concrete septic tank with an Orenco® ProPak Pumping system and PF3005 pump. • Install new pump line to automatic distributing valve, located in the northeast corner of the property. • Install a new STA. Design choice would be determined by soil evaluation. Assuming Soil Type 3 and no groundwater, 90 `Quick 4' infiltrator® or 6 rows of 15 (number and configuration may vary). (This is a summary of components and does not constitute a design). Please call with questions.
