- Interceptors are large sewers that collect flow from trunk sewers and transport it to wastewater treatment plants. They do not connect to homes or streets. Grease interceptors are plumbing devices used in restaurants to intercept greases and solids before wastewater enters disposal systems.
- Manholes and inspection chambers provide access to sewers and drains for maintenance. Manholes are the largest access points, with minimum dimensions of 600x900mm. Inspection chambers are shallower access points for cursory inspections and access by maintenance equipment.
The document summarizes a wall-mounted fiber optic enclosure called the WBF6-24. It can hold up to 24 fiber connections, has separate splice and patch areas, and four cable entries. It provides flexibility for installers by supporting different connector styles and allowing reconfiguration without disturbing installed fibers. Accessories include pigtails, bulkhead adapters, splice sleeves, and patch cords.
The STT system is a modular technical flooring system consisting of (1) an embedded grid of ducts for electrical, data, and other installations and (2) access points called "knots" that allow installation and maintenance of these systems. It provides a long-lasting, fire-proof, and easily modifiable flooring solution that hides installations but allows permanent access. The system can be customized for different building requirements and allows flexible reconfiguration of installations without disrupting the floor or workspace layout.

Silva Cells are a modular shoring system used to support pavements
and create void spaces between the pavement and underlying soils
that can then be filled with planting soil or other media to facilitate tree
growth as well as water infiltration

9. 8Integrating Silva Cells and Utilities
There are a number of different ways for integrating Silva Cells with
both new and existing utilities
Integrating Silva Cells and Utilities
10. Integrating Silva Cells and Utilities 9
The most commonly used option is to run utilities through Silva Cells.
Due to the open design of the frames, they can accommodate pipes,
conduits, and other underground utilities up to 10” (250 mm) in
diameter.

When integrating Silva Cells and utilities, it may not always be possible
to run utilities through the Cells. In those cases, one of the following
alternatives may be used:
• Aggregate gap detail
• Bridging utilities with Silva Cells
• Bridging utilities with small concrete slabs (< 24” wide)
• Bridging utilities with custom concrete slabs (> 24” wide)
• Running utilities outside of the Silva Cell frames but in the
same excavation ares
Please refer to the details on our website (www.deeproot.com) for more information.

Geogrid
One of the simplest options is to leave a gap in the Silva Cells where
the Utility is. Then wrap the inside of the gap with geogrid and fill the
void space with clear stone (drain rock) to make a stone column. The
tree roots will work their way through the stone.

essentially the same time as
it would be during a

*Note that the lightly
compacted soil in the Silva

sides of the excavation than
traditionally compacted soil
which helps the excavation
stay open better

There are two ways to approach restoring that area
depending on the time frame in which the work must be
completed and the available materials:
1. Restore the area temporarily at the time of the repair
and do the permanent restoration at a later date.
2. Restore the area permanently at the time of the repair
using one of three permanent restoration options.

Restoration Options
69. 68
When time is limited, the area can be
quickly restored by backfilling the
excavation with a lean concrete mix
like U-fill or compacted aggregate and
temporarily patching the pavement …
… Then at a later the date the area
can be re excavated and restored
permanently using one of three
permanent restoration options.

Restoration Options
70. 69
Option 1 – fill/compact the excavation to the
bottom of the Silva Cells and re install new or
salvaged frames and decks
Option 2 – fill/compact the excavation up to the
bottom of the uppermost layer of Silva Cells and re
install a single layer of frames and decks
Option 3 – fill/compact the excavation to the
bottom of the Silva Cells, install geogrid around the
perimeter of the remaining opening and fill with
compacted soil, clear stone or U-fill (in the case of
U-fill try to establish some link between adjacent
soil volumes)

72. Conclusion 71
There are many options for integrating Silva Cells with both new
and existing utilities.
Plan for the future wherever possible.
Planned and emergency repairs are not much different with Silva
Cells and there are different restoration options available depending
on the circumstances.
