Written by GovTribe AI · Aug 7, 2026

This is a set of construction design drawings for the Town of Clayton Depauville Wastewater Treatment Plant (WWTP) Disinfection System Improvements project located in Jefferson County, New York. The project, designed by St. Lawrence Engineering DPC and Fourth Coast Inc., includes the installation of a new UV disinfection building with associated process improvements to the existing wastewater treatment facility. The scope of work encompasses construction of a new UV disinfection system with three UV reactors (2 duty, 1 redundant) configured in series, a new effluent pump station with variable speed pumps rated at 3 HP with a design flow of 100 gallons per minute (GPM), a post-aeration manhole with diffuser assembly and blower system, new piping installations including 3-inch DR11 HDPE and 8-inch SDR 35 PVC lines, a new 200-amp electrical service with emergency generator, a propane tank, and a new concrete sidewalk. The design accommodates average daily flow of 0.034 million gallons per day (MGD) based on historical maximum month average daily flow of 0.038 MGD, with peak instantaneous flow capacity of 0.310 MGD (215 GPM). The project drawings include comprehensive site plans, process flow diagrams, detailed electrical and mechanical specifications, manhole restoration details, erosion control measures including silt fence installation, and pipe bedding specifications. The SPDES permit number is NY 0215791, and the drawings were revised as of January 16, 2026, with the review set dated October 1, 2025.

The project involves coordination with multiple existing structures including four existing 5,000-gallon septic tanks, sand filters, distribution boxes, and dosing chambers. Construction activities require contractor responsibilities for site restoration, lawn establishment with specified seed mixtures, erosion and sediment control implementation, utility coordination, dewatering, and material backfill. The design specifies UV transmittance requirements of 35-80% UVT with maximum water hardness of 855 mg/L, and includes detailed specifications for equipment such as submersible effluent pumps, cooling system assemblies with 1/2 HP jet pumps, and aeration systems with 20 standard cubic feet per minute (SCFM) capacity across two redundant blowers. The project includes provisions for Build America, Buy America (BABA) and American Iron & Steel (AIS) compliance, with the related sealed bid for REBID Contract No. 2 (Collection System Rehabilitation and Manhole Restoration) due on July 23, 2026, at 2:00 p.m. local time, with 19 base bid manhole restoration locations and potential additional locations based on available funding.

APPLICATION NOTES:

A. THE PRIMARY PURPOSE OF A SILT FENCE OF SEDIMENT FILTER LOG IS TO INTERCEPT SEDIMENT LADEN RUNOFF BY IMPOUNDING WATER BEHIND THE FENCE OR LOG SO THAT SEDIMENT FALLS OUT

OF SUSPENSION.

B. IDENTIFY ONSIDE AND OFFSITE RESOURCES THAT NEED TO BE PROTECTED USING THE SILT FENCE OR SEDIMENT FILTER LOG (E.C. WETLANDS, PONDS, WATERWAYS, OR ENVIRONMENTALLY SENSITIVE AREAS). SILT FENCE OR SEDIMENT FILTER LOGS ARE TYPICALLY USED WITH EROSION OR SEDIMENT

CONTROL MEASURES, SUCH AS MULCH AND/OR ROLLED EROSION CONTROL FABRIC.

C. SILT FENCE OR SEDIMENT FILTER LOGS SHALL NOT BE USED IN OR ACROSS A FLOWING CHANNEL, OR

AREAS OF CONCENTRATED FLOW. DO NOT USE SILT FENCE OR SEDIMENT FILTER LOGS AS A

PERIMETER CONTROL, TO DEFINE PROPERTY LINES, OR TO DELINEATE A RESOURCE.

GENERAL NOTES:

1. SILT FENCE OF SEDIMENT FILTER LOGS SHALL BE INSTALLED ON A LINE OF EQUAL ELEVATION (CONTOUR). IT MAY BE INSTALLED AT INTERMEDIATE POINTS UP SLOPES AS WELL AS AT THE

BOTTOM.

2. FOR LOCATIONS THAT WARRANT PLACEMENT OF SILT FENCE OR SEDIMENT FILTER LOGS AT THE BASE OF SLOPES, SILT FENCE OR SEDIMENT FILTER LOGS SHALL BE PLACED A MINIMUM OF 10 FEET FROM THE TOE OF THE SLOPE. TO PROVED ADEQUATE AREA FOR SEDIMENT STORAGE AND FACILITATE

MAINTENANCE OF THE SEDIMENT CONTROL AREA.

3. THE ENDS OF A ROW OF SILT FENCE OR SEDIMENT FILTER LOGS SHALL BE ANGLED UP SLOPE TO PREVENT CHANNELIZED FLOW FROM BEING CONVEYED PAST THE ENDS OF THE FENCE. A SECTION OF

SILT FENCE OF SEDIMENT FILTER LOGS SHOULD NOT EXCEED 100 FEET IN LENGTH.

4. WOOD POSTS FOR SILT FENCE SHALL HAVE A CROSS-SECTION AREA OF 3.5 SQUARE INCHES OR STEEL POSTS SHALL BE "T" OR "U" SHAPE AND 1.33 POUND/FEET (MINIMUM) FOR STEEL. SPACING FOR THE PROVIDED SILT FENCE POSTS SHALL BE AS DESIGNATED ON THE DEPARTMENT APPROVED LIST FOR SILT FENCE. THE LENGTH OF SILT FENCE POSTS SHALL BE 40 INCHES. WOOD POSTS FOR SEDIMENT FILTER LOGS SHALL BE NOMINAL 2X2. THE LENGTH OF FILTER LOG POSTS SHALL BE 16" GRATER THAN

THE DIAMETER OF THE LOG.

5. THE BOTTOM EDGE OF SILT FENCE SHALL BE BURIED A MINIMUM OF 6" BELOW GROUND. THE FENCE

SHALL BE INSTALLED WITH THE POST ON THE DOWNSLOPE SIDE OF THE FABRIC.

6. WHERE ENDS OF GEOTEXTILE FABRIC COME TOGETHER, THEY SHALL BE OVERLAPPED AND FOLDED AND STAPLED TO PREVENT SEDIMENT BYPASS, OR THE END POSTS OF TWO SECTIONS SHALL BE

WRAPPED AS SHOWN IN THE DETAIL FOR SILT FENCE END WRAPPING.

7. SEDIMENT SHALL BE REMOVED WHEN ACCUMULATION REACHES ONE-HALF OF THE ABOVE GROUND

HEIGHT OR WHEN BULGES DEVELOP IN THE FABRIC. SEDIMENT SHALL BE DISPOSED OF AS

UNSUITABLE MATERIAL.

8. THE FOLLOWING ARE MAXIMUM SLOPE LENGTHS (DISTANCE BETWEEN ROWS) FOR SILT FENCE

INSTALLATION.

* FOR SLOPES LESS THAN 5% SILT FENCE IS NOT REQUIRED UNLESS IN SENSITIVE AREAS OR HIGHLY

ERODIBLE SOIL

** STANDARD SILT FENCE IS FABRIC ROLLS STAPLED TO WOODEN POSTS DRIVEN 18 INCHES INTO THE

GROUND

*** REINFORCED SILT FENCE IS FABRIC PLACED AGAINST WELDED WIRE MESH WITH ANCHORED STEEL

POSTS DRIVEN 18 INCHES INTO THE GROUND.
