Manhole inspection cameras are indispensable tools for municipalities, contractors, and industrial operators, enabling the efficient inspection of underground infrastructure without the need for direct human entry. These devices are subject to some of the harshest conditions imaginable, including extreme temperatures, water submersion, corrosive environments, and physical shocks. To withstand ...
In the field of underground infrastructure inspection, technological advancements play a crucial role in ensuring accuracy, speed, and safety of operations. In this context, RinnoVision has established itself as a key reference thanks to its manhole inspection cameras. Designed to meet the specific needs of municipalities, utility companies, and construction contractors, the RV-MAX 360 and RV-PRO ...
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 ...
In many organizations, inspections are done seriously. Teams take the time to document, fill out reports, take photos, and write observations. At the moment they are performed, inspections do their job. They answer a very specific question: what is the condition of this asset today? But a few months later, that same inspection often loses its value. Six months go by—sometimes less—and ...
The inspection of sewer manholes and underground infrastructure represents a major challenge for municipalities and utility companies. Traditional methods are not only time-consuming, but also involve significant risks for worker safety. In this article, we examine how remote inspection technologies make it possible to reduce inspection time by up to 75% while improving safety and the quality of ...
When it comes to testing and blocking pipes, pipe plugs are super useful tools. But have you ever heard of a bypass connection? If you’re new to this field or just curious, don’t worry, we’ll explain it in a simple way! What is a bypass connection? Why it’s important? Which PlugCo products have bypass options? A comparison table of plugs with and without bypass ...
These improvements required a small underground stormwater detention system. The discharge from the detention system needed to tie into an existing stormwater line at a shallow elevation, which required a low-profile, high-volume detention system. The Engineer of Record chose 18” tall StormTank Module 25 Series units for the underground ...
The water recovered at the outlet of the system has a maximum residual hydrocarbon content of 5 mg / L, in accordance with the criteria of the water law. On the design side, the high flow hydrocarbon filter is integrated in a concrete manhole or in a metal casing. The system also has a pre-filter and absorbent media packaged directly into the ...
It is a place of difficult access with limited means to enter and exit that are accessed usually by means such as ladders, iron steps, polypropylene manhole steps or by lifting systems with harness. They do not have a natural ventilation so the atmosphere is deficient in oxygen and accumulate polluting, toxic and flammable ...
Surely, more than once, you have noticed, while walking down the street that the vast majority of the manhole covers that you have passed in front of, were round. Possibly you had never asked yourself the reason; in the current post we are finally going to discover what is behind that mystery, whose answer has a lot to do with math. A manhole cover is used to ...
They also managed to increase their efficiency and save time on maintaining water utility infrastructure, hydrants, manholes, water meters, etc. (We already wrote about them a couple of years ago here.) ...
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. If not ...
Cost Savings A vacuum sewerage system almost always costs less to install than a gravity flow system because our vacuum system uses small pipe in shallow, narrow trenches, and there are no manholes. ...
Inflow and Infiltration When flooding or ponding occurs over sanitary manholes, and if there are any openings or cracks in your manhole covers, it will inevitably cause inflow into that system. ...
Existing Manholes In some wastewater situations, it’s possible to measure the flow using a vault or an existing manhole. ...
Performance History and Discussion In-Pipe Technology implemented the first phase of a collection system Professional Services Program in 2001. Beginning in 2002, additional collection system basins were added to the services program. ...
Solution We helped Young Homes close escrow on the 95 homes in its Perris, CA development when the Eastern Municipal Water District (EMWD) required them to upsize a 10-inch ID clay trunk sewer line to 12-inch ID pipe to create a sufficient fall between the last two manholes in its system. EMWD had specified bench construction for the excavation because a quarter ...
Description Severe deterioration of the town’s sewer system called for a comprehensive manhole rehabilitation project that included permanent rehabilitation of 34 manholes. Baskerville Donovan chose to use the Poly-Triplex System to structurally enhance the structures and to stop the infiltration of groundwater. ...
The purpose of this study was to quantify the spatial variation in FOG deposit formation and accumulation in a pilot-scale sewer collection system. The pilot system contained straight pipes, manholes, roots intrusion, and a pipe sag. Calcium and oil were injected into the system and operated at alkaline (pH = 10) and ...
Functions designed to optimize the link between CTSpec and the ESRI ArcView GIS system would make it possible to create and generate multilayered thematic maps providing an instant visual of the City’s systems. Solution CTSpec Sewer was therefore implemented. The resulting system made it possible to quickly establish a complete inventory ...
