About this file
This set of engineering design drawings is for the PR-WWTP Clarifier Upgrades project for Newport Utilities, located in Newport, Tennessee, prepared by W.K. Dickson & Co., Inc. in February 2025. The project involves rehabilitating two existing clarifiers at the Newport Wastewater Treatment Plant, with specific upgrades including replacing below-waterline components such as the clarifier center well, rake, drive shaft, and lower bearing. The design documents provide detailed technical specifications, site plans, and installation instructions for the clarifier rehabilitation, with comprehensive drawings (G-00 through C-3) detailing existing conditions, project location, clarifier details, and section views.
The project will take place at 465 Lisega Blvd in Newport, Tennessee, with a designated contractor staging area adjacent to the wastewater treatment plant. The technical specifications emphasize strict adherence to Newport Utilities' ordinances, policies, and standard specifications, as well as Tennessee Department of Environment and Conservation (TDEC) administrative codes. All materials, equipment, labor, and workmanship must comply with these regulations, with the more restrictive requirements taking precedence. The contractor will be responsible for utility location, damage prevention, and precise installation techniques, including specific leveling and alignment procedures for the clarifier mechanism.

NOTES:
1. MAKE SURE THERE ARE (4) BENCH MARKS ON THE TANK WALL LABEL EACH MARK AS SHOWN (A, B, C & D) AND LOCATE THEM INLINE WITH THE
LEVELING BOLTS ON THE DRIVE UNIT (W, X, Y & Z)
2. CLAMP A 4' LEVEL ON THE TOP SIDE OF THE SCRAPER ARM SO IT EXTENDS TO THE TANK WALL.
3. NOTE: IT IS IMPORTANT THAT BOTH ARMS ARE AT THE SAME BEVEL OR ANGLE.
4. MARK ONE ARM "#1" AND THE OTHER "#2"
5. ROTATE ARM "#1" TO LOCATION "A"
6. FROM THE LEVEL MEASURE TO THE BENCH MARK ON THE TANK WALL DIM "X"
7. CONTINUE AROUND THE TANK AND NOTE THE MEASUREMENT AT EACH LOCATION (A, B, C & D)
8. COMPARE THE MEASUREMENTS BETWEEN POINTS (A & C) AND (B & D)
FOR EXAMPLE:
** AT POINTS (A & C) THE MEASUREMENTS FOR ARM #1 ONLY WERE ----- A= 5 1
2 AND C= 6 12
THE " DEAL" MEASUREMENT WE ARE LOOKING FOR IS (6'')
SO, ARM "#1" NEEDS TO BE RAISED AT POINT "C" OR LOWERED AT POINT "B"
IT IS ALWAYS EASIEST TO SHIM THE UNIT "UP" AT THE LOW POINT, LOCATION "C"
9. LOOSEN THE BOLTS ON THE DRIVE UNIT AND ADJUST THE LEVELING BOLT AT LOCATION "Y"
NOTE: SHIMMING THE DRIVE 1
32 OF AN INCH COULD MOVE THE ARM ENOUGH SO IT IS LEVEL
IT IS ALWAYS BEST TO DO SMALL INCREMENTS.
10. REPEAT AT POINTS (B & D)
11. RECHECK ALL POINTS WHEN COMPLETED.
12. SHOP APPLIED PRIMERS ARE INTENDED TO BE A TEMPORARY COATING, APPLIED FOR PROTECTION DURING TRANSIT, STORAGE AND ERECTION.
13. ALL STEEL ITEMS TO BE 304L SSTL MATERIAL U.N., WELDED USING ER308 ELECTRODES WITH WELDING PERFORMED BY CERTIFIED WELDERS
PER AWS D16.
14. CONTRACTOR TO VERIFY AND IDENTIFY ANY BASIN WALL, PENETRATIONS, PROTRUDING EQUIPMENT, OR PIPING THAT MAY INTERFERE WITH
THE ROTATING MECHANISM.
