INFLOW AND INFILTRATION REDUCTION

Our experts implement simple, environmentally safe projects to create proactive and reactive solutions to sanitary sewer capacity issues.

FIND, PRIORITIZE, & REMEDIATE DEFECTS IMPACTING YOUR SANITARY SEWER INFRASTRUCTURE

We recognize the costly impacts that can arise from Inflow and Infiltration (I/I) in sanitary systems. With our expertise and experience in identifying, prioritizing, and remediating I/I defects, we can help to prevent these events from happening. Our projects improve conditions and resiliency of sanitary sewer systems, improve infrastructure on private property while ensuring stakeholder satisfaction, and we have a unique delivery model to improve and increase capacity in sanitary sewer systems, while allowing new developments to proceed. The projects will defer the need for adding new system capacity, saving you extraordinary costs.

BENEFITS OF OUR SERVICES

Civica works to reduce the risk of liability associated with I/I and to provide the following benefits:

ELIMINATE I/I RELATED FLOODING

Rainfall derived I/I is becoming more of a concern for sanitary sewer system capacity with the increasing instances of basement flooding and sewage overflows to the environment. Our proven I/I reduction methodologies will greatly reduce the flow of extraneous water entering your system, resulting in a net benefit to the community.

MINIMIZING CAPITAL EXPENDITURES

With the sustainable population and community growth, it is essential to avoid unnecessary costs of repairing or building infrastructure and decrease costs to residents with more efficient sewage management.

OUR I/I REDUCTION TOOLBOX

FM-9

FLOW MONITORING

Monitoring of the dry weather and wet weather flows within the sanitary sewer infrastructure is performed and the resulting data is analyzed in relation to rainfall data. Areas with increased flow rates during major rainfall events will indicate possible I/I.

SMOKE TESTING

Our experienced field technicians conduct smoke testing of problem areas to identify the possible source of I/I.

DYE TESTING

To further confirm that the suspected I/I source is channeling rainwater into sanitary line, a dye testing procedure is performed.

MAINTENANCE HOLE INSPECTIONS

We assess maintenance holes (MHs) conditions to detect areas of I/I based on the location relative to surrounding topography; cracked or broken seals within the shaft; and/or evidence of I/I within the shaft (stains, dripping, etc).

CCTV

CLOSED-CIRCUIT TELEVISION (CCTV)

This video inspection of sewer mainlines, laterals, and manholes provide an inside look at the condition of your sewer systems to identify sources of leakage, causes of blockages, and possible need for structural repairs

WET WEATHER INSPECTIONS

Significant coordination and planning of rain events and selected pipes are completed to discover I/I entering buried sewers. We determine the impacts of laterals, foundations of drains, and rapid infiltration of groundwater when there are high antecedent moisture conditions to discover additional defect areas.

DATACURRENT

Detailed data about the I/I sources are recorded in our internally developed software, DataCurrent. DataCurrent is used to generate graphical, map-oriented reports to use for efficient planning efforts to remediate the problem sources.
