About this file
This file comprises detailed civil and electrical construction plans for the Yellowstone Modular Housing project (YELL 326141), prepared by Stantec for the National Park Service. The plans cover utility infrastructure, electrical distribution, and site restoration specifications across three primary locations: Mammoth, Northeast Entrance, and Canyon Village.
The civil details specify utility trench construction, water and sewer line installation and separation requirements, fire hydrant installation (Mueller Super Centurion 250 model), sanitary sewer service lines with grinder pump systems (Zoeller Simplex 48" x 120" specification), water meter installation compatible with Flexnet Radio Read systems, and thrust blocking for water line fittings. Critical specifications include water service line separation standards (minimum 10-foot horizontal separation from sewer lines, with 18-inch vertical clearance minimum), pipe bedding and backfill compaction requirements (95% relative compaction per FP-24 specifications), and cement-treated backfill (flowable fill) composition for areas where standard separation cannot be maintained. Water pressure reducing valves (PRVs) are required for services exceeding 80 PSI. The electrical plans detail underground conduit routing, communications vaults, pad-mounted transformer installations coordinated with Northwestern Energy and Flathead Electric, combination 200-ampere meter sockets with disconnects at each modular unit, and compliance with NEC 2026 standards. Electrical loads per unit total 35 kilowatts with conduit sizes ranging from 1.5 inches to 3 inches. The plans also include specifications for restoration of disturbed areas, culvert installation with riprap end treatment, modular block retaining walls (Recon Wall Systems), and utility marking tape and tracer wire requirements. All work requires coordination with the Contracting Officer and existing utility providers, with junction boxes and conduit routing to be verified and submitted prior to installation.

NOTES
1. NO EXCEPTION TO THE MINIMUM HORIZONTAL OR VERTICAL SEPARATION REQUIREMENTS ARE PERMITTED WHEN THE SEWAGE-CARRYING PIPE IS A FORCE MAIN. SERVICE LINES MAY DEVIATE FROM THE 10' REQUIREMENT IF
APPROVED BY CONTRACTING OFFICER.
2. AT CROSSINGS, ONE FULL LENGTH OF WATER LINE PIPE SHALL BE LOCATED SO THAT BOTH JOINTS WILL BE AS FAR
FROM THE SEWER LINE AS POSSIBLE.
3. "L" IS A STANDARD LENGTH OF PIPE AS SUPPLIED BY A PIPE MANUFACTURER.
4. WHERE THE 10-FOOT HORIZONTAL SEPARATION CANNOT BE MAINTAINED, THIS SEPARATION MAY BE REDUCED, PROVIDED THE BOTTOM OF THE WATER LINE IS AT LEAST 18 INCHES HIGHER THAN THE TOP OF THE SEWER LINE
AND THE FOLLOWING ADDITIONAL REQUIREMENTS ARE MET IN ACCORDANCE WITH WPWSS;
A. THE SANITARY SEWER OR STORM DRAIN SHALL BE CONSTRUCTED OF MATERIALS AND WITH JOINTS THAT ARE
EQUIVALENT TO WATER MAIN STANDARDS OF CONSTRUCTION AND SHALL BE TESTED FOR WATER TIGHTNESS BY SEWER LINE METHODS PER SPECIFICATION 33 00 00, OR THE SANITARY SEWER, STORM SEWER, OR WATER MAIN SHALL BE PLACED IN A SEPARATE CASING PIPE. IN EITHER METHOD, THE LENGTH OF SEWER LINE OR
CASING PIPE SHALL EXTEND A MINIMUM OF 9-FEET ON EACH SIDE OF THE CROSSING, AND;
B. WATER MAINS PASSING UNDER SEWER LINES SHALL, IN ADDITION TO THE ABOVE REQUIREMENTS, BE PROTECTED BY PROVIDING ADEQUATE STRUCTURAL SUPPORT FOR THE SEWER LINE. SOIL STRUCTURAL SUPPORT SHALL CONSIST OF CEMENT TREATED BACKFILL (FLOWABLE FILL) BEARING ON UNDISTURBED SOIL.
5. WHEN THE REQUIRED HORIZONTAL AND/OR VERTICAL SEPARATIONS BETWEEN WATER LINES AND SEWER LINES CANNOT BE MET, THE SEWER MAY BE ENCASED IN ONE FOOT OF CEMENT TREATED BACKFILL (FLOWABLE FILL).
6. CEMENT TREATED BACKFILL (FLOWABLE FILL) SHALL MEET THE FOLLOWING CRITERIA:
INGREDIENTS LBS/CY
CEMENT (0.45 SACK) 42
WATER (39 GALLONS) 325
COARSE AGGREGATE (SIZE NO. 57) 1,700
SAND (ASTM C-33) 1,845
THE MAXIMUM DESIRED 28-DAY STRENGTH SHALL BE 30-60 PSI. THERE IS NO COMPACTION REQUIREMENT FOR
CEMENT TREATED BACKFILL.
7. CEMENT-TREATED FILL MATERIALS & INSTALLATION SHALL COMPLY WITH WYOMING DEQ CHAPTER 12 REGULATIONS.
