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 the most demanding industrial and municipal settings, equipment reliability isn’t optional — it’s essential. Inspections of pipelines, manholes, or confined spaces often expose tools to extreme conditions: moisture, heat, chemicals, mud, vibrations, and more. This is the challenge RinnoVision set out to solve with the RV-MAX 360, a cutting-edge inspection camera designed ...
Across North America, underground infrastructure is showing its age. Many manholes and sewer chambers are more than 60, 80, or even 100 years old. ...
Among the most important tools to ensure rigorous monitoring of the condition of sewer manholes, the MACP (Manhole Assessment and Certification Program), developed by NASSCO, is today the reference standard in North America. Among the different coding levels, MACP Level 2 stands out as the most complete and detailed assessment, used to gain an ...
The inspection of sewer manholes and underground infrastructure represents a major challenge for municipalities and utility companies. ...
Microwaves generated by radar reflect off various liquid and solid material surfaces, enabling reliable level measurements for many industry applications such as: Water level monitoring in stormwater and sewer (gases) manholes Outdoor environmental flood monitoring in rivers, lakes and oceans Municipal and industrial wastewater tanks with surface foam and ice ...
Beginning early in 2019 our office began receiving complaints of sewer odor in the neighborhood of Fountain Ridge Section III (FR III), located in Prince George County VA. The County Operations staff investigated the wastewater collection system that serves the neighborhood, and found that odor was proliferating throughout the neighborhood. Corrosion of the sewer ...
This article explains the reasons why you should add a sewer camera to your list of business equipment including the benefits it will provide to you as well as your clients. Are you providing sewer repairs and similar solutions to clients in your business? If so, then it’s important to make sure that you are investing in the right technology and equipment. One of the best examples of this ...
Inspection cameras used in pipelines, plumbing systems and storm drains are designed to help professionals inspect and diagnose problems in pipes and sewer systems. A visual inspection is the key to identifying existing or potential problems in these hard-to-reach structures. Usually located under the ground, drains, sewers, manholes and other ...
Odour, corrosion and safety risks in sewer network caused by changing weather and climate. The changing climate and weather patterns on sewer management add further complexity for utility operators. ...
H2S is colorless, flammable, poisonous, and corrosive gas with one sulfur atom bonded to two hydrogen atoms. Also, known as sewer gas, swamp gas, or manure gas. H2S has a noticeable rotten-egg odour detectable at concentrations as low as 0.5 ppb. ...
Utility: The City of Perryville Location: Perryville, MO Applications: Wastewater Products: HTT-900 & HTT-3100 Distributor: Municipal Equipment Company, Inc. The City of Perryville The sewer department for the City of Perryville operates and maintains the city’s wastewater system, serving a population of approximately 8,500 residents. Their wastewater system ...
Both programs consist of three main elements: Procedures Companies that produce concrete storm sewer and culvert pipe, manholes, sanitary sewer pipe, box culverts, three-sided precast structures and other precast concrete products are expected to maintain "sufficient procedures and documentation" to demonstrate their products are consistently ...
The data enabled the project team to show an almost immediate reduction in I/I. 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 ...
The additive stimulates the indigenous bacteria population living in the sewer to accelerate natural biodegradation. The grease is rapidly metabolized by the bacteria in the sewer, not just solubilized. ...
The number of treatment plants receiving and beneficially using trucked-in wastes currently in operation or under investigation is increasing rapidly across the North America as utilities strive to remove this material from normal wastewater to avoid sewer system clogging, maintenance and backups, avoid the oxygen demand of these wastes in secondary treatment systems, and to ...
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. ...
If using an existing manhole is your only option for accessing your wastewater flow, you should be sure to use a Palmer-Bowlus flume, a type of flume expressly designed for measuring piped sewer flows. Packaged Metering Manholes The majority of wastewater flows will be too large to measure using an existing manhole. In these ...
In addition, it can be used for such applications as a manhole or sewer inspection and, in general, whenever there is a need to access tight areas that open up into larger ...
Pluvial flooding in urban areas is characterized by a gradually varying inundation process caused by surcharge of the sewer manholes. Therefore urban flood models need to simulate the interaction between the sewer network and the overland flow in order to accurately predict the flood inundation extents. In this work we present a methodology ...
