In the field
Specified by cities
Many municipalities require it
A growing number of cities now require contractors to use a debris catcher on any project involving manhole digging, repair, or adjustment. If your specification requires one, the Grappler Manhole Debris Catcher meets it.
The Contractor shall furnish and utilize an umbrella-type device to prevent debris from entering the sewer system during construction.
The device shall be as manufactured by Grappler Specialty Products or City approved equal.
The use of a manhole debris catcher equal or equivalent to that provided by Grappler Specialty Products (www.grapplerusa.com) must be used when rehabilitating and or constructing new manholes, catch basins, and structures. The intent is to catch falling debris such as concrete grout mixture, soil, etc.
Furnish materials to catch all manhole debris such as a manhole debris catcher provided by Grappler Specialty Products (www.grapplerusa.com) or an approved equal.
Contractor must use this device when rehabilitating and or constructing new manholes on an interceptor sewer.
Features
- Reduces confined space entries
- Reduces sewer backups
- Removes the need for jetting or vacuum truck service
- Straightforward to deploy, with rapid debris removal
- Constructed for sustained field use
One size accommodates most standard structures. The Rope & Hook is required to deploy and retrieve the unit on standard casting adjustments, so it is included with every Debris Catcher unless you choose otherwise.
Operating instructions
- Before starting rehabilitation, lower the Debris Catcher with the J-hook and rope to the bottom of the manhole structure. Center the bottom plastic bridge over the invert.
- Slowly allow the basket to open. Make sure the Debris Catcher is laying flat.
- Remove the J-hook and rope. Start repairs.
- When work is finished, pull out the Debris Catcher with the debris in it.

Why cities specify one
Debris that goes down has to come back up
Spoil from a casting adjustment that reaches the invert does not stay there. It becomes a blockage, and a blockage upstream of somebody's basement becomes a claim. The Debris Catcher is lowered and lifted on a rope from the surface, and the debris comes up with it.
of a city’s general liability losses
Sewer backups into private property account for roughly this share of the general liability insurance losses municipalities carry each year.
average claim, and that is the cheap one
The average sewer loss for an unfinished basement. A typical claim across all backups runs into the mid thirty thousands, and finished space costs more.
The other cost is the entry itself
Going down after the debris is not a quick look. Manhole work puts a contractor under OSHA's confined spaces standard, and a routine entry on an ordinary day still means all of this:
- Identify and evaluate the hazards of the space before anybody enters it
- Test the atmosphere in sequence: oxygen first, then combustible gases, then toxic gases
- Monitor the atmosphere continuously while the entry is open
- Station an attendant outside the space for the whole of the entry
- Arrange rescue services and have the rescue equipment on hand
- Issue a written entry permit, and cancel it when the work is done
A sewer cannot be isolated the way a tank can, because the rest of the
system is still connected to it. OSHA puts it plainly:
If the employer demonstrates that isolation of the space is infeasible because the space is large or is part of a continuous system (such as a sewer), the employer must test conditions in the permit space to determine if acceptable entry conditions exist.
See
OSHA, Confined Spaces in Construction, 29 CFR 1926 Subpart AA
and
Confined Spaces in Construction: Sewer Systems (OSHA 3789).
Every load that comes up in the basket is an entry nobody has to plan, permit, staff or stand by for.
