Regular maintenance of underground infrastructure is critical to the safety, functionality, and longevity of a city’s sewer system. Manholes serve as vital access points to these networks, allowing inspection teams to assess the condition of pipelines and related components. In the past, inspecting manholes required physically entering these confined spaces, often exposing workers to ...
Project Review Our co-owners Sue and Al have installed a triple-sealed pro line aluminium recessed manhole cover at their new home. The slim aluminium frame design creates an aesthetic look against the pattern wooden floor. Due to the manhole cover location, it is highly recommended to use a triple-sealed instead of double-sealed. This is ...
Here is a garden project to turn a spacious area into a lawn. There is a manhole chamber in the location, therefore a GrassTop cover has proven to be an ideal addition. ...
A Florida Municipality Finds an Efficient System for Preventing Corrosion in Manholes The City of Pace, Fla., located near Pensacola in the Florida panhandle, was experiencing significant corrosion in its manholes that made maintenance and construction of its wastewater system increasingly costly and inefficient. ...
The rehab area was defined as sewers and manholes within the 100-year floodplain in four basins. GIS was used to identify parts of the system that met these criteria and ultimately to compile maps containing nearly 700 map tiles per set for field crews doing manhole and TV line inspections. ...
Slope of the pipe lines are very high. The water head inside the manhole reach 15 meters for some locations. PlugCo Team provided Practical and theoretical usage training for the pipe plugs. ...
Description This project, completed in 2002, included 17 manholes located within the Yellowstone National Park. The manholes had significant deterioration from wastewater chemical corrosion. ...

Results suggest that 3% of public network manholes were vulnerable to flooding during an 11-year long rainfall sequence. A Chicago Design Storm (CDS) incorporating a 10-minute rainfall burst with a 5-year return period predicted twice as many flooded manholes at similar locations. A 20% increase in CDS intensity increased the number ...
Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. ...
One alternative is to remove odorous compounds in the gases vented from manholes using adsorptive media. In this study, odour control devices located at manholes were observed to determine the ability of these systems to reduce hydrogen sulphide from vented gases. The odour control devices incorporated pressure regulation to control gas flow out ...
To deploy each unit, a township technician selected a manhole location, attached a stainless steel bracket in the influent pipe, then mounted the sealed, ultrasonic sensor into it. The technician connected the sensor cable to the watertight electronic logging unit and hung it inside the manhole. The logger recorded the date and time, water level, ...

The design was changed to include two 400-foot (121.9 m) runs to install the 10-inch (25.4 cm) gravity line through the affected area using an established manhole location as an entry and exit point. DeKalb selected two different HDD subcontractors; one for the two 400-foot (243.8 m) gravity shots and another for about 2800 linear feet (853.4 m) of force main ...

The overland flow network features (ponds and flow pathways) generated by this methodology are dependent on the number of sewer network manholes and sewer inlets, as some of the overland flow pathways start at manholes (or sewer inlets) locations. Thus, if a simplified version of the sewer network has less manholes (or sewer ...
