Did you know? A small leak in a manhole or a pipe joint can generate 7,200 gallons of water annually or that 35% of water entering a water treatment plant is due to Inflow and Infiltration. Every gallon of wastewater is transported and treated; there are ways to reduce the costs of the transportation and treatment. Part of the expenses is clearwater entering the wastewater system; clearwater is also known as Inflow and Infiltration. Below you will find information about Inflow and Infiltration and how Trinity Subsurface, LLC can help solve the problem!
Infiltration is defined as any excess groundwater that enters through holes, cracks, fractures, breaks, joint failures, root intrusion, and defective connections. This can be influenced by storm events, seasonal changes, sea level, and change to impervious coverage to the surface; all of these examples cause an elevated level of groundwater to be present.
Inflow is defined as excess stormwater that flows from roof drains, holes in manhole lids, uncapped cleanouts, storm drain cross connections, and unknown connections. Weather events such as rainfall, snowfall, and snow melt aid in the excessive water flow.
Together these types of excess water in a sewer system are called Inflow and Infiltration, or I&I for short. I&I is a problem because many collection systems and treatment centers cannot handle the additional capacity of water, new sewer systems may need to be rebuilt to keep up with increased flow, increased amount of flow causes a decrease in the capability to treat the wastewater, environmental and health hazards, and higher operating costs for treatment and collection. I&I can be found in several areas of a sewer system; these areas include the manholes, laterals, and main pipes.
Trinity Subsurface, LLC offers both preventative services, evaluation services, and rehabilitative services. Before I&I is eliminated, it must be identified. The preventative services that Trinity Subsurface, LLC include video pipe inspection, manhole inspection, flow monitoring, smoke testing, and dye testing. Preventative maintenance helps identify key areas for repair within a sewer system. Trinity Subsurface, LLC’s video pipe inspection team uses robotic crawlers and manhole cameras with CCTV to find each I&I defect within a system; this method of inspection eliminates the need for direct access of a technician to complete the inspection, making the inspection a safe way to gather I&I information.
Once the defects in a system are identified, Trinity Subsurface LLC deploys its NASSCo certified experts to evaluate the defects and make suggestions on repairs. Trinity Subsurface, LLC’s pipe repair team will then perform the suggested and approved repairs to the system. Trinity Subsurface, LLC uses several types of repair methods. One of the methods used is sectional point repair; this type of repair can single out specific I&I defects in a main line pipe. The next type of repair is manhole to manhole lining; if there are many I&I within a pipe, then the entire pipe may need to be lined. Prevent, evaluate, and repair I&I at the source, by using Trinity Subsurface, LLC’s easy to work with and highly knowledgeable Pipe Services experts today.
