About this file

Written by GovTribe AI · Apr 20, 2026

This is a drawing set for a gas collection and control system expansion at the Old Dixie Highway Municipal Solid Waste Landfill operated by the Dalton-Whitfield Solid Waste Authority in Dalton, Georgia. The project involves the 2026 expansion of the landfill gas collection and control system (GCCS) and was issued for bid on April 6, 2026. The drawing set, prepared by SCS Engineers (Stearns, Conrad and Schmidt Consulting Engineers, Inc.), includes nine sheets detailing existing conditions, proposed site plans, base grades, and comprehensive construction details. The project encompasses the installation of multiple landfill gas extraction wells, header and lateral piping systems of varying diameters (4 inches to 12 inches), condensate sumps with pumps, remote wellheads, air supply lines, liquid conveyance lines, and horizontal collectors. The design includes specifications for well bore reinforcement grates, perforated HDPE pipe configurations, isolation valves, air release valves, and tie-ins to existing leachate collection systems. The proposed system incorporates extraction wells (EW-60 through EW-72), multiple horizontal collectors (HC-1 through HC-19), and support infrastructure including valve isolation stations and monitoring ports.

The drawings establish detailed construction standards and specifications including minimum slope requirements (5 percent for headers and laterals, 3 percent for horizontal collectors), pressure testing protocols (4 PSIG for LFG lines, 100 PSIG for air and liquid conveyance pipes), and material requirements such as HDPE SDR 17 and SDR 11 piping, Schedule 40 PVC casing, and stainless steel components. Construction quality assurance requirements are emphasized, including surveying of well locations and alignments prior to construction, liquid level measurements within 24 hours of well completion, and field verification of existing conditions. The document specifies that locations and installations may vary to accommodate field conditions with engineer and responsible official approval, and contractor shall immediately notify the engineer of any obstructions or impacts to implementation. No specific contract pricing, award date, or completion timeline is provided in this drawing set; it serves as the technical specification basis for the competitive bidding process.

3. ALL HORIZONTAL COLLECTOR PIPING INSIDE THE LIMITS OF WASTE SHALL BE A

MINIMUM OF 3% SLOPE, UNLESS APPROVED BY THE ENGINEER OR RESPONSIBLE

OFFICIAL.

4. ABOVE AND BELOW GROUND UTILITIES AND OTHER EXISTING FEATURES IN THE

PROJECT AREA, SHALL BE FIELD-LOCATED BY THE CONTRACTOR PRIOR TO

CONSTRUCTION. IF THE CONTRACTOR ANTICIPATES THAT ANY OF THESE FEATURES

WILL IMPACT ABILITY TO IMPLEMENT THE DESIGN SHOWN ON THESE DRAWINGS

OR WILL REQUIRE ADDITIONAL DESIGN CONSIDERATIONS, THE CONTRACTOR

SHALL IMMEDIATELY NOTIFY THE ENGINEER / CONSTRUCTION QUALITY

ASSURANCE (CQA) REPRESENTATIVE.

5. LOCATIONS AND INSTALLATION OF THE PROPOSED LANDFILL GAS EXTRACTION

WELLS, REMOTE WELLHEADS, AND HEADER/LATERAL PIPE ALIGNMENTS MAY

VARY TO ACCOMMODATE FIELD CONDITIONS. ANY MODIFICATIONS TO THE

PROPOSED SITE PLAN SHALL BE APPROVED BY THE ENGINEER AND RESPONSIBLE

OFFICIAL BEFORE IT IS CONSTRUCTED.

6. WELL LOCATIONS MAY HAVE TO BE CHANGED IF AN ENCOUNTERED OBSTRUCTION

CANNOT BE PASSED DURING DRILLING. THE CONTRACTOR/DRILLER SHALL INFORM

THE ENGINEER OF SUCH OBSTRUCTIONS, BASED ON WHICH, THE WELL LOCATION

MAY BE ABANDONED FOR FURTHER DRILLING. THE ENGINEER SHALL COORDINATE

WITH THE CONTRACTOR TO RE-SURVEY A NEW LOCATION FOR THE WELL AND

ADJUST THE WELL SCHEDULE AS NECESSARY BASED ON THE NEWLY COLLECTED

SURVEY DATA. DRILLING SHALL COMMENCE ONLY AFTER ALL NECESSARY

SIGNATURES ARE OBTAINED ON THE UPDATED WELL SCHEDULE.

7. CARE SHALL BE TAKEN TO AVOID DAMAGING EXISTING FEATURES AND

STRUCTURES DURING CONSTRUCTION ACTIVITIES, INCLUDING BUT NOT LIMITED

TO EXISTING GCCS COMPONENTS, TRAFFIC SIGNS, LITTER FENCE, ETC. IF ANY

DAMAGE IS MADE DUE TO CONTRACTOR ACTIVITIES, CONTRACTOR SHALL

RESTORE THE DAMAGED STRUCTURE TO PRE-CONSTRUCTION CONDITIONS AT THE

CONTRACTOR'S EXPENSE.

8. EXCLUDING STUB-UPS, CONTRACTOR SHALL NOT USE 90° MOLDED ELBOWS OR

TEES ON LIQUID CONVEYANCE LINES. CONTRACTOR SHALL ONLY USE 90° SWEEP

BENDS OR 45° WYES, WHERE APPLICABLE.

9. CONTRACTOR SHALL SURVEY AND STAKE THE HEADER/LATERAL PIPE ALIGNMENTS

PRIOR TO CONSTRUCTION FOR APPROVAL BY THE ENGINEER AND OWNER.

10. CONTRACTOR IS TO LET CQA INSPECTOR TAKE SYSTEM PRESSURE READINGS ON

VACUUM STUB-UPS BEFORE THE LATERAL IS RAN TO THE NEWLY DRILLED WELL.

11. ALL WELDS SHALL BE BUTT WELDS, AND NO ELECTROFUSION COUPLERS SHALL BE

USED WITHOUT APPROVAL OF THE ENGINEER.

12. THE 10" VACUUM LATERAL WILL REQUIRE DEEP TRENCHING BY AN ADDITIONAL 2

FEET.

13. HDPE LATERALS AND CONNECTIONS TO LFG HEADER, AIR SUPPLY LINES, AND

LIQUID CONVEYANCE PIPELINES SHALL BE SUBJECTED TO PRESSURE TESTS AS

DESCRIBED HEREIN TO DETECT ANY LEAKS IN THE PIPING. TESTING SHALL BE

PERFORMED BELOW GRADE (INSIDE THE TRENCH). THE TEST PRESSURE FOR LFG

LATERALS, AND HEADERS SHALL BE 4 PSIG. THE TEST PRESSURE FOR AIR SUPPLY

LINE AND LIQUID CONVEYANCE PIPES SHALL BE 100 PSIG. PRESSURE DROP DURING

THE TEST SHALL NOT EXCEED ONE PERCENT OF THE TESTING GAUGE PRESSURE

OVER A PERIOD OF ONE HOUR. THIS PRESSURE DROP SHALL BE CORRECTED FOR

TEMPERATURE CHANGES BEFORE DETERMINING PASS OR FAILURE. THE CQA

PERSONNEL SHALL SIGN OFF ON THE TEST FORM TO INDICATE TEST COMPLIANCE.

IN CASE OF FAILURE OF TEST, THE LEAK SHALL BE LOCATED BY THE CONTRACTOR

AND REPAIRED. SUBSEQUENTLY, THE LINE SHALL BE RETESTED.

14. EXISTING AIRLINE AND LIQUID CONVEYANCE PIPING ARE 2" SDR 9 HDPE PIPE.

CONTRACTOR SHALL CONFIRM WITH CQA INSPECTOR THAT EACH PIPE IS

PROPERLY IDENTIFIED BEFORE CONNECTING TO THE PROPOSED GCCS.
