Creston City Council approved the adoption of the inflow and infiltration policy during their regular meeting Tuesday. The I and I policy will not take effect until Jan. 1, 2013 meaning that any property listed, or closed, on Jan. 1, 2013 or after will need to be compliant with the new I and I regulations.

Inflow and infiltration is the invasion of water into the sanitary sewer system from broken, cracked or misaligned mains, leaking manholes or manholes that have water flow over their covers. Other sources include private services (resident and business).

The I and I policy is designed to remove inflow and infiltration from the sanitary sewer system.
