LOCATION OF SANITARY SEWERS IN RELATION TO
WATER AND STORM SEWERS:
A. SEWERS SHALL BE LAID AT LEAST 10 FEET HORIZONTALLY FROM ANY EXISTING OR
PROPOSED WATER MAIN. THE DISTANCE SHALL BE MEASURED EDGE TO EDGE. IN CASES
WHERE IT IS NOT PRACTICAL TO MAINTAIN A 10 FOOT SEPARATION, THE APPROPRIATE
REVIEWING AGENCY (DEH OR DENR) MAY ALLOW DEVIATION ON A CASE BY CASE BASIS, IF
SUPPORTED BY DATA FROM THE DESIGN ENGINEER. SUCH DEVIATION MAY ALLOW
INSTALLATION OF THE SEWER CLOSER TO A WATER MAIN, PROVIDED THAT THE WATER
MAIN IS IN A SEPERATE TRENCH OR ON AN UNDISTURBED EARTH SHELF LOCATED ON ONE
SIDE OF THE SEWER AND AT AN ELEVATION SO THAT THE BOTTOM OF THE WATER MAIN IS
AT LEAST 18 INCHES ABOVE THE TOP OF THE SEWER.
B. IF IT IS IMPOSSIBLE TO OBTAIN PROPER HORIZONTAL AND VERTICAL SEPARATION AS
DESCRIBED ABOVE OR ANYTIME THE SEWER IS OVER THE WATER MAIN, BOTH WATER
MAIN AND SEWER MUST BE CONSTRUCTED OF FERROUS PIPE COMPLYING WITH PUBLIC
WATER SUPPLY DESIGN STANDARDS AND BE PRESSURE TESTED TO 150 PSI TO ASSURE
WATERTIGHTNESS BEFORE BACKFILLING.
C. A 24 INCH VERTICAL SEPARATION SHALL BE PROVIDED BETWEEN STORM SEWER AND
SANITARY SEWER LINES OR FERROUS PIPE SPECIFIED.
CROSSINGS:
A. SEWERS CROSSING WATER MAINS SHALL BE LAID TO PROVIDE A MINIMUM
VERTICAL DISTANCE OF 18 INCHES BETWEEN THE OUTSIDE OF THE WATER MAIN AND THE
OUTSIDE OF THE SEWER. THE CROSSING SHALL BE ARRANGED SO THAT THE SEWER
JOINTS WILL BE EQUIDISTANT AND AS FAR AS POSSIBLE FROM THE WATER MAIN JOINTS.
B. WHEN IT IS IMPOSSIBLE TO OBTAIN PROPER HORIZONTAL AND VERTICAL
SEPARATION AS STIPULATED ABOVE, ONE OF THE FOLLOWING METHODS MUST BE
SPECIFIED
I. THE SEWER SHALL BE DESIGNED AND CONSTRUCTED OF FERROUS PIPE
AND SHALL BE PRESSURE TESTED AT 150 PSI TO ASSURE WATERTIGHTNESS PRIOR TO
BACKFILLING, OR
II. EITHER THE WATER MAIN OR THE SEWER LINE MAY BE ENCASED IN A
WATERTIGHT CARRIER PIPE WHICH EXTENDS 10 FEET ON BOTH SIDES OF THE CROSSING,
MEASURED PERPENDICULAR TO THE WATER MAIN. THE CARRIER PIPE SHALL BE OF
MATERIALS APPROVED BY THE REEGULATORY AGENCY OF USE IN WATER MAIN
CONSTRUCTION.

ALL CONSTRUCTION SHALL BE IN ACCORDANCE WITH TOWN
OF BENSON STANDARDS AND SPECIFICATIONS.
A. SEWERS SHALL BE LAID AT LEAST 10 FEET HORIZONTALLY FROM ANY EXISTING OR PROPOSED WATER MAIN. THE
DISTANCE SHALL BE MEASURED EDGE TO EDGE. IN CASES WHERE IT IS NOT PRACTICAL TO MAINTAIN A 10 FOOT
SEPARATION, THE APPROPRIATE REVIEWING AGENCY (DEH OR DENR) MAY ALLOW DEVIATION ON A CASE BY CASE BASIS, IF
SUPPORTED BY DATA FROM THE DESIGN ENGINEER. SUCH DEVIATION MAY ALLOW INSTALLATION OF THE SEWER CLOSER
TO A WATER MAIN, PROVIDED THAT THE WATER MAIN IS IN A SEPERATE TRENCH OR ON AN UNDISTURBED EARTH SHELF
LOCATED ON ONE SIDE OF THE SEWER AND AT AN ELEVATION SO THAT THE BOTTOM OF THE WATER MAIN IS AT LEAST 18
INCHES ABOVE THE TOP OF THE SEWER.
B. IF IT IS IMPOSSIBLE TO OBTAIN PROPER HORIZONTAL AND VERTICAL SEPARATION AS DESCRIBED ABOVE OR ANYTIME
THE SEWER IS OVER THE WATER MAIN, BOTH WATER MAIN AND SEWER MUST BE CONSTRUCTED OF FERROUS PIPE
COMPLYING WITH PUBLIC WATER SUPPLY DESIGN STANDARDS AND BE PRESSURE TESTED TO 150 PSI TO ASSURE
WATERTIGHTNESS BEFORE BACKFILLING.
C. A 24 INCH VERTICAL SEPARATION SHALL BE PROVIDED BETWEEN STORM SEWER AND SANITARY SEWER LINES OR
FERROUS PIPE SPECIFIED.
CROSSINGS:
A. SEWERS CROSSING WATER MAINS SHALL BE LAID TO PROVIDE A MINIMUM VERTICAL DISTANCE OF 18 INCHES
BETWEEN THE OUTSIDE OF THE WATER MAIN AND THE OUTSIDE OF THE SEWER. THE CROSSING SHALL BE ARRANGED SO
THAT THE SEWER JOINTS WILL BE EQUIDISTANT AND AS FAR AS POSSIBLE FROM THE WATER MAIN JOINTS.
B. WHEN IT IS IMPOSSIBLE TO OBTAIN PROPER HORIZONTAL AND VERTICAL SEPARATION AS STIPULATED ABOVE, ONE
OF THE FOLLOWING METHODS MUST BE SPECIFIED
I. THE SEWER SHALL BE DESIGNED AND CONSTRUCTED OF FERROUS PIPE AND SHALL BE PRESSURE TESTED AT
150 PSI TO ASSURE WATERTIGHTNESS PRIOR TO BACKFILLING, OR
II. EITHER THE WATER MAIN OR THE SEWER LINE MAYBE ENCASED IN A WATERTIGHT CARRIER PIPE WHICH
EXTENDS 10 FEET ON BOTH SIDES OF THE CROSSING, MEASURED PERPENDICULAR TO THE WATER MAIN. THE CARRIER
PIPE SHALL BE OF MATERIALS APPROVED BY THE REEGULATORY AGENCY OF USE IN WATER MAIN CONSTRUCTION.

PHASE 2 EROSION AND SEDIMENT CONTROL CONSTRUCTION SEQUENCE:
1. CONTINUE ROUGH GRADING SITE TO BRING PROJECT AREA TO FINAL GRADE. ADJUST EROSION CONTROL MEASURES DAILY TO FIT NEW SITE
GRADES AS LAND AREA IS BROUGHT TO FINAL ELEVATION.
2. CONTINUE WORK ON THE NEW FIELD HOUSE, BASEBALL FIELDS, AND MULTIPURPOSE FIELDS.
3. BEGIN INSTALLATION OF ANY STORM DRAINAGE PIPING, WATER, AND SANITARY SEWER IN THE PROJECT SITE. INSTALL HARDWARE CLOTH INLET
PROTECTION TO PREVENT SEDIMENT FROM ENTERING THE STORM DRAIN NETWORK AS SOON AS NEW STORM INLETS ARE INSTALLED.
4. DIRECT ALL STORMWATER RUNOFF TO THE SEDIMENT BASIN AS NECESSARY FROM ALL DISTURBED SOILS. DO NOT PERMIT SEDIMENT LADEN
WATER TO ESCAPE OFFSITE WITHOUT FLOWING THROUGH THE SEDIMENT BASIN.
6. FINE GRADE ALL PAVED AREAS AND INSTALL ROADWAY SUBGRADE, CURB AND GUTTER, AND OTHER SITE FEATURES.
6. COMPLETE PAVING AND CONCRETE FLATWORK AREAS. INSTALL LANDSCAPING AS SHOWN ON THE LANDSCAPING PLAN.
7. ONCE SITE IS FINE GRADED, DISTURBED SOILS ARE STABILIZED, SEEDED, AND SODDED, AND BUILDING CONSTRUCTION IS SUBSTANTIALLY
COMPLETE, THE CONTRACTOR MAY REMOVE THE SKIMMER SEDIMENT BASINS. REMOVE COIR MESH SEDIMENT BAFFLES, TRASH, AND OTHER
ACCUMULATED DEBRIS. REMOVE THE SKIMMER DEVICE AND SEAL THE EXISTING DRAINAGE STRUCTURES WITH WATERTIGHT SEAL.
8. FINE GRADE, SEED, AND STABILIZE THE AREAS PREVIOUSLY OCCUPIED BY THE SKIMMER BASIN AS SHOWN ON THE PLANS.
9. IF CONSTRUCTION IS COMPLETE, SCHEDULE A FINAL INSPECTION WITH NCDEQ INSPECTIONS STAFF. IF THE SITE IS APPROVED, REMOVE
TEMPORARY DIVERSIONS, SILT FENCE, BASINS, ETC. AND SEED OR STABILIZE ANY REMAINING BARE AREAS. ALL REMAINING PERMANENT EROSION
CONTROL DEVICES, SUCH AS VELOCITY DISSIPATORS, SHOULD NOW BE INSTALLED.

APPROVED BY ENVIRONMENTAL ENGINEER.
TOP OF BERM MAINTENANCE
EMERGENCY INSPECT TEMPORARY SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1/2 INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE
SPILLWAY SEDIMENT AND RESTORE BASIN TO ITS ORIGINAL DIMENSIONS WHEN IT ACCUMULATES TO ONE-HALF THE DESIGN DEPTH. PULL THE SKIMMER TO ONE SIDE SO THAT THE
ELEVATION SEDIMENT UNDERNEATH IT CAN BE EXCAVATED. PLACE REMOVED SEDIMENT IN AN AREA WITH SEDIMENT CONTROLS.
MAKE SURE VEGETATION GROWING IN THE BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE SKIMMER.
IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASING, USUALLY JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE
THE DEBRIS AND RESTORE FLOW. IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE SIDE OF THE BASIN AND REMOVE THE DEBRIS. ALSO CHECK THE ORIFICE
DISSIPATER INSIDE THE SKIMMER TO SEE IF IT IS CLOGGED; IF SO REMOVE THE DEBRIS.
PAD IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH
RIP RAP WATER. BE SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.
FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS SHOULD BE TAKEN IN THE WINTER TO PREVENT THE SKIMMER FROM
PLUGGING WITH ICE.
CHECK THE EMBANKMENT, SPILLWAYS, AND OUTLET FOR EROSION DAMAGE AND INSPECT THE EMBANKMENT FOR PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIRS
IMMEDIATELY. REMOVE ALL TRASH AND OTHER DEBRIS FROM THE RISER AND POOL AREA.
