as communities face the burden and costs of increasingly\u00a0stringent wastewater treatment standards<\/a>, the need for\u00a0sanitary sewer system maintenance\u00a0and flow monitoring couldn\u2019t be stronger. through regular observation, sewer system deterioration, defects, and flow issues can be identified. as a result, communities can take a proactive approach to keep their sanitary sewer system functioning properly and avoid unexpected costs. the wastewater experts at snyder & associates have been providing this critical service to our client communities for many years.<\/strong><\/p>\n flow monitoring uses equipment to read and record flow depth and rate to determine if issues are resulting from inflow\/infiltration (i\/i), or both. using the data gathered, it\u2019s possible to\u00a0plan and design a sanitary sewer rehabilitation approach<\/a>\u00a0to\u00a0correct (i\/i) issues\u00a0at targeted locations. once sewer rehab is complete, another round of flow monitoring is often beneficial to illustrate how effective the improvements are. in addition to i\/i investigations,\u00a0flow monitoring\u00a0is also helpful for:<\/p>\n flow monitoring equipment consists of two parts \u2014 a monitor\/logger and a sensor. the monitor\/logger is installed below a specific manhole cover to record and store information gathered by the sensors that read the sewer flow. information can be downloaded in the field directly from a laptop or uploaded to the cloud via satellite or cellular connection for viewing on a desktop computer or a smartphone app.<\/p>\n based on a community\u2019s needs and constraints, there are four sensor types to choose from \u2014 three are in-flow and the other is a long-range sensor that doesn\u2019t come in contact with wastewater.<\/p>\n in-flow sewer monitoring<\/strong><\/p>\n the first type of in-flow sensor mounts on the bottom of a sewer pipe. velocity, depth, and temperature measurements are gathered as wastewater flows past the unit. an ultrasonic depth sensor within the unit bounces a radar beam off the water surface and back down to gain depth information. if the pipe is full due to surcharging, a surface isn\u2019t available for the ultrasonic depth sensor to read. in these instances, a pressure-depth sensor can be used to read what\u2019s going on in the pipe.<\/p>\n using pressure-depth sensor results in the most accurate velocity reading because it averages velocity throughout the entire depth of the flow and accounts for surcharging. however, human entry is required for installation, which is a disadvantage. the sensor also requires a minimum flow depth to work and excessive debris can easily foul the sensor.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n the third type of in-flow sensor mounts on top of the pipe. it shoots a beam down into the flow that bounces off the surface to measure velocity. not every sensor comes equipped to measure pressure, but it\u2019s an option to measure surcharge conditions. because the sensor installs on the top of the pipe, it\u2019s less susceptible to debris. however, human entry is still required for installation and these sensors are slightly more costly. additionally, velocity readings may not be as accurate as those provided by the bottom-mounted sensor because measurements come only from the surface.<\/p>\nwhat is flow monitoring?<\/span><\/h2>\n
