Inflow and Infiltration
Inflow and infiltration or I&I are terms used to describe the ways that ground water and stormwater enter into dedicated wastewater or sanitary sewer systems. Dedicated wastewater or sanitary sewers are created from pipes located in the streets or easements that are designed strickly to transport wastewater from sanitary fixtures inside your house or place of business. Sanitary fixtures include toilets, sinks, bathtubs, showers and lavatories.
Inflow is stormwater that enters the sanitary system through directly connected roof gutter downspout, driveway drains, area drains, storm drains, foundation drains, or defect in pipes. CENTER TOWNSHIP SANITARY AUTHORITY SPECIFICALLY PROHIBITS THE DISCHARGE OF STORMWATER INTO THE SANTIARY SEWERS. Refer to CTSA Rules and Regulations Article III.
BE SURE YOUR HOME OR BUSINESS DOES NOT HAVE AN ILLEGAL STORMWATER CONNECTION TO THE SANITARY SEWER
Infiltration is groundwater that enters the sanitary sewer systems through cracks and/or leaks in the sanitary sewer pipes.
WHY IS INFLOW AND INFILTRATION A PROBLEM
Overflow occurrences put public health at risk and violate state and federal environmental regulations. Sanitary sewer overflows release wastewater and potiental pathogens onto streets, into waterways and basements increasing potiental health risks. As wastewater overflows into creeks, rivers, lakes and streams it contaminates all bodies of water fed by the waterways and all creatures/plants coming in contact with the polluted water.
Inflow and Infiltration costs water treatment facilities and consumers large amounts of money in water treatment operating expenses. All water entering a water treatment facility must be treated as wastewater causing an increase in operating costs proportional to the amount of clean water entering the sanitary sewer system due to inflow and infiltration.
PREVENT LOSS FROM BACKUP
Homeowners are susceptible to wastewater backups in their homes due to blocked manhole conditions. In nearly ALL cases,because of the municipal tort law, the Center Township Sanitary Authority's Insurance Company nor the customers home owner's insurance pay for damages caused by these backups.
It is suggested that the customer add a rider to their homeowner's policy that will provide coverage for this backup damage.
