Smoky Hill Range Sewer Line Design

Salina, KS

The Smoky Hill Range Sewer Line Design project was driven by intermittent usage of the Crisis City training center, which was causing the existing lagoon to run dry. Through coordination with KDHE, it was decided to increase the sanitary sewer flow to the lagoon by connecting the Billeting area. The Billeting area has five existing septic systems and includes 10 dorms, two latrines, and two administration buildings. A third latrine for the Billeting area is currently under design by another firm. BG was responsible for converting a septic system into a collection system.

The new collection system included approximately 3,000 feet of force main and 3,000 feet of gravity sewer. Alignment for the new force main had to carefully weave through the firing range area. BG specified extra signage to increase awareness of the force main and air release valve location. As the project continues, the existing septic system will be completely removed, while the septic tanks will be cleaned, inspected, and possibly salvaged. Also included in this project was an above-ground 7.5 HP wet well mounted duplex lift station, which was chosen for its user-friendly design.

MEP services for this project were completed in-house and included provisions for a new electrical service to the site. Because the existing primary overhead power distribution is privately owned, BG had to design of a new primary power connection, utility transformer, and primary conduits to the site. New electrical distribution equipment included a manual transfer switch with connection capability from a temporary generator should the need arise. A remote cellular dialer was installed in the pump station equipment to allow remote alarm generation.
