No Open Trenches (Reduced Disruption):
A minimized excavation and construction footprint compared to open trench installations of gravity sanitary sewers means local businesses, streets and the landscape won’t suffer through the construction phase of the project. The reliable accuracy of line and grade for pilot tube installations means you can avoid existing utilities as well. Municipalities frequently realize significant savings by eliminating the need to rebuild roads.
Keeping businesses, including golf courses and shopping malls open and fully functioning throughout the project has proven to be a key benefit of trenchless installations. Supporting the political and economic drivers of a community can be invaluable.
The desire to preserve and protect environmentally sensitive areas have also driven the selection of trenchless methods of installation. Reduced congestion, reduced trucking activity and a low environmental disruption all combine to make trenchless the environmentally preferable installation method.
No Trench to Backfill (Reduced Trucking Materials):
Jacking and receiving pits are the only areas that require excavation, so those are the only areas that need to be restored. No open trench means minimal or zero imported bedding material or removal of trench spoils. Limited surface disruption also means minimal cutting of existing pavement and significant reduction in settlement.
Greater Depths (Reduce Lift Stations Greater Design Options):
The ability to install at greater depths for gravity sanitary sewers means you can reduce or eliminate lift stations, eliminating initial costs and reducing the associated long-term operating and maintenance expenses.
Why Pilot Tube Method with VCP?
- The most accurate small diameter trenchless method for gravity flow systems. Accurate to within ¼” over a single drive of 400’.
Why Trenchless Instead of Open Trench?
There are a host of reasons, but here are the key reasons engineers cite:
- No Open Trenches – Significantly reduces disruption to the community, utilities (including fiber optics), businesses, streetscapes and traffic patterns and eliminates the need to repair or replace streets.
