URETEK Provides Lasting Solution for Inflow & Infiltration (I&I) Challenges
With winter moving on and warmer weather approaching, state and local government officials anticipate the arrival of seasonal rains that can present serious challenges during the spring and early summer. In some areas, inflow & infiltration (I&I) issues following heavy rain events cause pump stations to experience a significant increase in flow, and wastewater treatment plants are pushed to their limits to keep up. Additional costs are passed along to taxpayers, and local governments with an eye on future development find that I&I seriously impacts their ability to follow through on promises of growth.
For cities trying to grow and expand their tax base, seasonal I&I issues can seriously limit their options and threaten their ability to sign future capacity letters for new commercial developments.
Repairs Delayed and Problems Compounded
Typical budget constraints force local governments to delay repairs on cracked and leaking manholes and wastewater pipelines, and this delay can compound one rainy year’s challenges and force local officials to face even more costly repairs in subsequent years.
In the past, dealing with I&I issues involved major construction projects with expensive timelines, heavy equipment, extensive excavation, traffic disruption, and the temporary interruption of services.
A New Approach to I&I in Indiana
In cities across the country, the concept of system “rehabilitation” has been shown to offer significant cost and time savings over traditional replacement of cracked and broken underground infrastructure assets. Leading the way with this improved approach is URETEK and its URETEK Deep Injection® (UDI) application.
A recent project illustrates this point clearly. For the city of Clarksville, Indiana, high rain events brought a 500% increase in pump station flow and an overall 300% increase at the wastewater treatment plant. With future commercial development hanging in the balance, city leaders needed to get to the bottom of whatever was going on with their wastewater treatment system.
CCTV analysis revealed that the suspected I&I issues were, indeed, the cause of the problems. The city evaluated all the options available to them and decided to go with URETEK because it was faster, less invasive, and of course less expensive.
Seven manholes were treated with UDI, and in less than two days Clarksville was back on track with its dream of brighter days and over a million dollars a year in wastewater treatment savings. URETEK offered a better solution, and much of the success of the project has to do with the material URETEK uses for these applications.
URETEK 486 Star® Polymer
URETEK 486 Star® polymer is a two-component, high-density, expanding thermoset polyurethane system that cures fully within an hour, and completely seals cracked and leaking underground pipes and manholes.
URETEK developed its polymer to be the ideal solution for under-sealing, void filling, lifting of settled pavement, stabilization and stiffening of weak soils, and for encapsulating and sealing buried infrastructure. URETEK 486 Star® is environmentally inert, non-toxic, and importantly in cases of I&I, resists underground water erosion or weakening due to its industry-leading hydrophobic properties.
