This document summarizes the trenchless pipe renewal project on Neversink Drive using pipe bursting and lateral reinstatement. Key aspects of the project included installing 800 feet of 8-inch HDPE pipe using static pipe bursting with 126 tons of force. Laterals were reconnected using Inserta Tees and SDR-35 PVC pipe for lower laterals. The renewal process minimized excavation and disruption to the community.

3. Neversink Drive
8” HDPE SDR-17
800’ in 3 Insertions

4. Site Survey
• Camera Mains
• Locate 18 Laterals
• Mark Utilities

5. Excavation
• 2 HydroVacs
• 2 Days
• 18 Lateral Connections
Benefit:
Minimized impact of construction,
particularly on adjacent utilities

6. Pipe
• 8” Polyethylene Pipe
• ASTM D1248 SDR-17
• 800 Feet
Benefit:
- (I & I) is totally eliminated.
- Total corrosion resistance.
- Cost-effective installation.

7. Manhole Reconnections
• Water Stops
• Link-Seal
Benefit:
- Permanently attached to pipe
by electrofusion
- Quick and easy installation

8. Lateral Reconnections
• Inserta Tee
• SDR-35 PVC Pipe
– Lower Laterals Only
Benefit:
Ease of installation and positive,
compression fitting directly into
new pipe. Eliminates glues,
epoxies, grouts, bands and
gaskets.

9. Renewal Method – Pipe Busting

10. TRIC WC44
• Static Puller
• 126 Tons @ 6,200
PSI
Benefit:
- Powerful tool yet compact tool
minimizes excavation
- Gimbals around adjacent utilities
- Operate inside existing manholes

11. Backfill
• Restoration of
work areas
Benefit:
Minimal excavation of entry
and exit pits leads to quick
and easy restoration of work
areas

12. Crews
