Once your flow monitoring system is in place and generating data, you can analyze that data to quantify and identify how much inflow and infiltration (I/I) is in your system.
Over time, we help you separate inflow from infiltration and determine where in your network the highest volume is coming from so that it can be targeted for reduction — whether the source is public or private. Our team can assist with prioritization and scheduling of rehabilitation projects to fit your capital plan and budget.
Few, if any, firms have done more private I/I work in than we have, starting with two of the largest programs in the nation for St. Louis and Kansas City. Our experience includes extensive work developing and managing system rehabilitations and I/I education studies, managing programs that touch more than 100,000 properties. We manage both internal and external private property evaluations and address the disconnect of those sources with a cost-effective approach.
We have teams of National Association of Sewer Service Companies-certified (NASSCO) field technicians and engineers who have performed hundreds of flow monitoring and sanitary sewer evaluation studies to quantify the challenges in collection systems. This work includes installation and management of flow meters, manhole inspection and closed-circuit television (CCTV) inspections. We identify private sources of stormwater entering sanitary collection systems. Our teams have managed inspections of more than 50,000 private properties.
The final step on a successful I/I program is to verify changes yield the expected results by continuing to collect and analyze flow metering data. We help you use your data to engage the public, helping residents understand the progress being made, the benefits of completed projects and the plans for further change.
