3.0 Identification of the Treatment Facility
The proposed River Bend Creek Lift Station will convey wastewater via a 4” force main to a manhole located approximately 1,300 ft east of the proposed lift station site. From this manhole wastewater will discharge by gravity to the existing Security Sanitation District Wastewater Treatment Facility (SSD WWTF) – refer to map in Appendix B. This Facility is owned and operated by SSD. The SSD WWTF has a permitted hydraulic capacity of 2.4 MGD and an organic capacity of 5,230 lb BOD5/day.
The following is an excerpt from The Pikes Peak Area Council of Governments (PPACG) Water Quality Management Plan (208 Plan) approved in 2011:
The Security Sanitation District (Figure 8-11) is in need of plant improvements for additional treatment of many parameters for the new NPDES permit. These are metals, ammonia, nitrate removal, and sludge handling. The design capacity of 2.4 mgd for the plant should be enough for build-out of the district. The current flow is about 1.27 mgd. Plans are being made for treatment system modifications to enhance treatment capability in the exiting site. Capital improvement costs are expected to be in the range of $5–7 million. Currently, Security is in the concept and design phase, and initial phased improvements commenced in 2009. Two lift stations – River Bend development and Waterview development – are expected in Phase 2. The Waterview development has installed a 12” outfall sewer across Grinnell Blvd. and down Bradley Rd. to the existing Windmill Gulch outfall. The facility discharges to the mainstem of Fountain Creek (Segment 2a) via a discharge location 3,000 feet upstream from the Carson Boulevard Bridge.
The proposed lift station service area is consistent with this plan in providing sewer service to the new ‘River Bend’ development within the established Security Sanitation District service boundary. The proposed lift station will not require an increase in the treatment capacity owned by SSD. Refer to Appendix D for the Inclusion Agreement from the SSD WWTF confirming that 100% of the wastewater from the River Bend Creek Lift Station will be accepted and treated by the SWSD WWTF. Refer to Appendix A for the Site Location Approval for the lift station by SSD.
