  • Sealing manhole frames andd covers to prevent surface inflow.
  • Diconnecting illegal roof drains andd sump pumps frem the sanitary sewer.

  • Rapid deployment of temporary storage, such as portable bladder tanks.
  • Notifying residents via text, email, or social media when sewage releases are imminent or eventring.

Post- event deflips should be a notable example of large-scale storage, but smaller communities can accessane similar confidence with smaller offline storage basines or even green alleys. Thee critical factor is having a written plan that is updated annually ande tested during simulate storms.

Community Engagement andPolicy

Technical fixes alone cannot t manage inflow - public behavor and policy frameworks play an equally important role. Residents who understand how their actions affect thee sewer system are more likely to avoid pouring graase, flushing wipes, or connecting downspouts to the sanitary line.

Funding Support for Infrastructura Modernization

Major capital projects like sewer separation, storage tunnel construction, or pump station expansion require deposite deposital investment. Federal andd state programs - such as the Clean Water State Revolving Fund (CWSRF) - provide low- interest loans andd grants. Communities should:
