About this file
These engineering design drawings detail the GAOA Flaming Gorge National Recreation Area (NRA) Water and Wastewater System Repair project for the Ashley National Forest in Utah. The project involves reconstructing approximately 1.5 miles of the Greendale public water system serving the Cedar Springs Campground and Marina area, with work including removal and replacement of existing water system infrastructure, pipeline, valves, pressure reducing valves, air-vacuum relief valves, and hydrants.
The base bid work scope includes removing existing structures and water system equipment, replacing water system pipelines and associated components, installing four pressure reducing valves with manholes, installing three air-vacuum relief valves, installing two water service hydrants, repairing existing roads, and constructing service roadway realignment. An optional work package provides for additional infrastructure removal, pipeline extension, and installing an additional pressure reducing valve. The project drawings provide detailed technical specifications for waterline routing, utility box configurations, valve and hydrant installations, trench details, and other critical infrastructure components across multiple station locations.

NOTES:
1. THE EXISTING WATER SYSTEM IS TO REMAIN IN SERVICE TO THE EXTENT POSSIBLE THROUGHOUT
CONSTRUCTION. INDIVIDUAL SERVICE CONNECTIONS ARE TO TRANSFERRED OVER TO THE NEW MAINLINE ONLY
AFTER THAT LINE HAS BEEN TESTED (PRESSURE AND BACTERIA) AND APPROVED FOR USE AS A PART OF THE
PUBLIC WATER SYSTEM. PLANNED OUTAGES FOR TRANSFER OF INDIVIDUAL SERVICES ARE TO BE COORDINATED
IN ADVANCE AS INDICATED IN THE SPECIFICATIONS REGARDING UTILITY INTERRUPTIONS..
2. UNPLANNED OR ACCIDENTAL UTILITY INTERRUPTIONS MUST BE RESTORED WITHIN 36 HOURS.
3. STAKING OF WATER SYSTEM LINES AND FEATURES SHALL BE COMPLETED BY THE CONTRACTOR AND APPROVED
BY THE CONTRACTING OFFICER PRIOR TO CONSTRUCTION.
4. NO SURVEY WAS PERFORMED FOR THIS PROJECT DESIGN. TOPOGRAPHY IS TAKEN FROM AERIAL
PHOTOGRAMMETRY AND IS INTENDED FOR SHOWING LARGE-SCALE ELEVATION DIFFERENCES AND TRENDS. IT IS
NOT SUITABLE FOR DETERMINING CONSTRUCTION ELEVATIONS. THE CONTRACTOR IS RESPONSIBLE FOR
ESTABLISHING BENCHMARKS AS NEEDED AND OBTAINING ACCURATE ELEVATIONS NECESSARY FOR INSTALLING
PRESSURE REDUCING VALVES AND OTHER EQUIPMENT WITH CRITICAL ELEVATIONS.
5. SUFFICIENTLY ACCURATE PROJECT ELEVATION BENCHMARKS WILL BE ESTABLISHED BASED ON RESERVOIR
WATER LEVEL ON THE DAY OF SURVEY. DAILY WATER ELEVATION CAN BE OBTAINED FROM THE BUREAU OF
RECLAMATION WEBSITE AT https://www.usbr.gov/uc/water/crsp/cs/fgd.html, OR AT THE NEARBY DAM VISITOR CENTER.
6. AN EXTENSIVE EFFORT HAS BEEN MADE TO LOCATE ALL POSSIBLE EXISTING UTILITY LINES FROM RECORDS AND
EVIDENCE IN THE FIELD. HOWEVER, MANY LOCATIONS ARE UNKNOWN AND THE COMPLETENESS OR ACCURACY
OF THOSE SHOWN CANNOT BE GUARANTEED. THE CONTRACTOR IS RESPONSIBLE FOR VERIFYING THE LOCATION
AND DEPTH OF ALL EXISTING UTILITIES.
7. PLANS SHOW EXISTING WATER SYSTEM EQUIPMENT TO BE REMOVED. EQUIPMENT DESIGNATED FOR REMOVAL;
INCLUDING VALVE BOXES, AND DRAIN LINES; ARE TO BE REMOVED TO AT LEAST 1 FOOT BELOW GRADE. METAL
MANHOLES ARE TO BE REMOVED ENTIRELY.
8. CAP OR PLUG ABANDONED WATER LINES TO REMAIN IN PLACE TO PREVENT PIPING OF GROUND OR SURFACE
WATER.
9. ALL WATERLINE SHALL BE SLOPED A MINIMUM 1% TO DRAIN EXCEPT WHERE SPECIFICALLY NOTED.
10. LOCATION AND ORIENTATION OF ALL STRUCTURES SHALL BE APPROVED BY THE CONTRACTING OFFICER
REPRESENTATIVE PRIOR TO INSTALLATION.
11. EXCEPT AS NOTED, BURY WATERLINE A MINIMUM OF 48 INCHES IN UNPAVED AREAS, AND 60 INCHES IN PAVED
AREAS. ADDITIONAL DEPTH MAY BE REQUIRED TO MAINTAIN REQUIRED SLOPES OR TO PROVIDE CLEARANCE
UNDER OTHER PIPELINES.
12. THE MINIMUM ALLOWABLE BENDING RADIUS FOR HDPE PIPE IS 30 TIMES THE NOMINAL PIPE DIAMETER, NOM. PIPE DIA. MIN. BEND RADIUS
1" 2'-6"
1.5" 3'-9"
2" 5'-0"
3" 7'-6"
4" 10'-0"
13. SLOPE SERVICE LATERALS TO DRAIN TOWARD THE MAINLINE.
14. INSTALL THE WATER SYSTEM IN ACCORDANCE WITH APPLICABLE FEDERAL AND STATE REGULATIONS FOR PUBLIC
DRINKING WATER SYSTEMS INCLUDING UTAH DIVISION OF DRINKING WATER R309-550.
15. CLEARING LIMITS SHALL BE A MAXIMUM OF 10 FEET ON BOTH SIDES OF THE WATERLINE TRENCH. THE
CONTRACTOR SHALL USE CAUTION TO AVOID DAMAGE TO TREES AND VEGETATION. THE CONTRACTOR SHALL
CONFINE ALL OPERATIONS TO WITHIN THE CLEARING LIMITS.
16. TRACER WIRE ACCESS POINTS SHOWN ON THE PLANS ARE FOR REFERENCE AS TO WHEN THEY ARE TO BE
INCLUDED WITH NEARBY VALVES OR OTHER UTILITY FEATURES. ACTUAL LOCATION SHOULD BE IMMEDIATELY
ADJACENT TO THE VALVES OR FEATURES SO THEY CAN BE READILY FOUND. SEE SPECIFICATION SECTION 330530
FOR MORE DETAILED INFORMATION ON ACCESS POINT AND WIRE LOCATION.

2. LID INTENTIONALLY HAS NO OUTSIDE DIAMETER SHOWN DUE
TO VARIATIONS IN CMP CORRUGATION DIMENSIONS AND
UNPREDICTABLE OUTSIDE DIAMETERS. THE FINAL PRODUICT
SHALL HAVE A LID WITH APPROXIMATELY 1/4" CLEARANCE
ALL AROUND TOP OF PROVIDED CMP. LID SHOULD FREELY
ROTATE AROUND TOP FOR POSITIONING WITHOUT BINDING.
3. WELD LOCKING ROD STRAPS ONTO CMP SUCH THAT THE
LOCKING ROD WILL FREELY ENGAGE BOTH STRAP HOLES
WITHOUT BINDING OR APPLYING PRESSURE TO LID.
4. HEIGHT OF UTILITY BOX AT STATION 79+92 MAY BE ADJUSTED
TO FIT FIELD CONDITIONS. SET BOTTOM OF BOX 1'-6" BELOW
