An ingress device assembly is configured to be used with a septic tank that has a chamber and an access opening and a riser extending from the chamber. The ingress device assembly includes a connector including a flange including a first section and a second section cooperatively defining a perimeter of the connector and an inner bore configured to align with the access opening, the first section having a first interlock feature and the second section having a second interlock feature engaged with the first interlock feature; and an ingress device removably and rotatably coupled to the connector, the ingress device including a body configured to extend across at least a portion of the access opening.

A removable obturation device is provided for transversely obstructing a passage delimited by a cylindrical side wall wherein it includes: a) a support and blocking element having a central block supporting a plurality of arms disposed perpendicularly in a radial position with respect to the longitudinal axis of the block and of the side wall, each arm having an extensible rod including a pad intended to be blocked against one the side wall, and b) at least one complementary obturation element extending in a radial transverse plane perpendicular to the longitudinal axis, at least partly in or opposite the space between the arms so as to prevent an individual from falling through the passage. The obstruction element is preferably removably fastened to the support and blocking element.

A method that includes obtaining a sensor reading from a sensor installed inside an underground vault and determining whether the sensor reading is indicative of an alarm state. When the sensor reading is indicative of the alarm state, the method obtains at least one new reading and determines whether the sensor reading includes sensor drift based at least in part on the at least one new reading. The alarm state is established when the sensor reading is determined not to include sensor drift. The sensor drift is removed when the sensor reading is determined to include sensor drift.

An integrated access box for providing surface access to a curb box or other structure, and tracer wires in a single unit. The integrated access box generally includes a body having a first end and a second end and a first chamber (e.g., a curb box chamber or cleanout chamber) extending into the first end toward the second end of the body. The body may be substantially cylindrical in shape, and may include a first opening near the first end of the body and a first chamber access opening in the first chamber near the top of the body, and a tracer wire chamber extending into the body. The tracer wire chamber includes a second opening near the first end of the body. The integrated access box may further include a tracer wire access opening in the tracer wire chamber near the top of the body.

An end seal placement tool for placing an end seal in a host pipe within a manhole includes a pole with opposite proximal and distal ends. An end seal holder is disposed at the distal end of the pole. The end seal holder includes an end seal chamber configured to hold the end seal. The end seal holder is sized and shaped to be at least partially inserted into the host pipe. A launcher is arranged with respect to the end seal holder for ejecting the end seal from the end seal holder into the host pipe.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

A manhole rehabilitation system where in one example an existing cross-pipe is exposed and a manhole base and riser are cast around and above the existing cross pipe to form a manhole. In one example an FRP base liner and FRP riser liner are placed before casting in place. In one example casting is made of an aggregate. In one example, a collar and manhole cap rest upon the casting, and are supported thereby such that the liner need not be structural. In one example an existing pipe or manhole forms the outer surface of the casting. In one example shoring is placed and used as the outer surface of the casting.

A valve box for accessing a utility valve, the valve box having a box housing with an inner surface and an outer surface. The outer surface may have a plurality of fins, and the inner surface may have a plurality of keyways configured to receive a plurality of keys. The inner surface may additionally have threading. The box housing may have an access opening in some embodiments, and the valve box may include a threaded valve box cover configured to be arranged over the access opening. In some embodiments, the box housing may have a plurality of modular rings. A valve box tool may have a driving portion, a valve box engaging portion, and a stem portion. The valve box engaging portion may have a plurality of keys configured to engage the plurality of keyways. The stem portion may be configured to extend between the driving portion and a valve.
