Why must I bring my building sewer up to code?
The City of Pacifica has four major issues to deal with involving its’ sewer system.
Inflow, Infiltration, Overflow, and Exfiltration
are problems the City is trying
to combat.
Inflow is water discharged directly into a
sewer system from such sources as, roof
runoff, area drains, and foundation
drains.
Infiltration is when groundwater leaks
into broken or cracked sewer pipe during
wet weather and the whole system can be
overloaded due to this condition.
Overflow is sewage overflow from either
manholes or cleanouts
Ex-filtration is sewer leaking out through
broken or cracked pipe that may
contaminate ground water or receiving
water. A significant portion of the inflow
and infiltration in this City originates
from old leaky building sewer. As the
City continues to grow, and the system
grows older, this problem will only
intensify.
