Case Studies for the Identification and Quantification of Sanitary Maintenance Hole Inflow and Infiltration (I&I)

MH water management

Sanitary sewer capacity can be quickly overwhelmed during large rainfall or snowmelt events. Maintenance holes (MH) —even ones not in low-lying areas—can become submerged and produce an inflow of water to sanitary systems. Inflow and infiltration inspections are designed to assess sanitary sewer capacity analysis, giving you a more comprehensive picture of your wastewater asset…

Methodology for the Identification and Quantification of Sanitary Maintenance Hole Inflow and Infiltration (I&I)

field services civica

During heavy rains and snowmelt, streets are designed specifically to channel water into ponding areas. In some circumstances, however, the amount of rainfall can be such that maintenance holes become submerged, exceeding the sanitary sewer capacity and causing floods. An inflow and infiltration inspection can help quantify storm water inflows through submerged maintenance holes, allowing…

Challenges of the New Subdivision Flow Monitoring to Assess Performance of Inflow and Infiltration (I/I) Prevention

Sewer Inspection Services

The innovative New Subdivision I/I Prevention Program has yielded great results for multiple municipalities when it comes to infiltration and inflow (I/I) reduction. That said, it doesn’t mean that the new subdivision I/I prevention plan is without its challenges. Let’s take a look at some of those challenges laid out in the flow monitoring plan.…
