Inflow & Infiltration (I&I) happens when ground and storm water seep into a sanitary sewer system<\/a> through defects within a collection system. Cross connected public infrastructure, downspouts, sump pumps, driveway drains, stairwells, and streams can all contribute to I&I.<\/p>\n Effective erosion control measures are crucial to managing I & I, to help reduce water pollution and protect property. Since manholes can contribute significant inflow and infiltration, it\u2019s important to inspect them to identify any signs of leaks or erosion.<\/p>\n I&I can result from the use of poor construction materials and outdated methods. It\u2019s an unfortunate fact that some contractors raise manholes using bricks or concrete grade rings to build the riser.\u00a0 These methods require grouting at all mating joints and then sealing the interior with a sealant, usually of cement.\u00a0 This kind of riser structure does not allow for the installation to be height \/ slope accurate and is subject to rapid deterioration.<\/p>\n When it comes to preventing I&I, it is important to inspect the following sources and causes of manhole leaks and deterioration. These include:<\/p>\n By eliminating mating joints and use of grout, the WhirlyGig Manhole Riser is the most effective solution to stopping I&I in wastewater systems. Easy to install, our high-quality, pre-formed thermoplastic forms<\/a> are constructed to outlast other manhole risers and has the added benefit of being more cost effective and of higher quality\u00a0 With our manhole riser solution I&I is a thing of the past and you can look forward to at least 25 years of maintenance-free service.<\/p>\n At WhirlyGig<\/a>, we provide a manhole riser solution that inherent to its design results in a much easier, more cost effective, higher quality and safer installation compared to traditional methods such as concrete grade rings.\u00a0 With the Whirlygig Manhole Riser solution you \u201cSet it an forget it!\u201d and can expect at least 25 years of maintenance-free service<\/p>\n Want to learn more?
