CMOM (Capacity, Management, Operation & Maintenance) - Also known as the
SSO Rule, this proposed regulation sets stringent guidelines for the capacity,
management, operation and maintenance of municipal sanitary sewer collection
systems.
CSO Policy - Sets short
(nine minimum controls) and long-term (long-term control plan) requirements for municipal
combined sewer collection systems.
Cleanout - An opening which
allows for removing any debris or obstruction that might block the flow of
wastewater.
Clean Streams Law -
State regulation similar to the Clean Water Act. Enforced by the Pennsylvania Department
of Environmental Protection, this law is one of the first such environmental laws in the
country to bring industrial wastes under legal control.
Clean Water Act - A 1977
amendment to the Federal Water Pollution Control Act of 1972, which set the basic
structure for regulating discharges of pollutants to waters of the United States. The
Act, enforced by the Environmental Protection Agency, prohibits any sanitary sewer
overflows and requires that combined sewer overflows be controlled to three or four
annually.
Combined Sewer
Overflows (CSOs) - When a combined sewer is too full of rainwater and sewage,
untreated sewage is discharged through design structures. This is designed to occur
during wet weather, but can also occur due to poor operation and maintenance. Overflows
also can occur through overflowing manholes or basement backups.
Combined Sewer
System - A system that is designed to carry both stormwater and sewage in the same
pipe. Combined sewer system communities are regulated by the CSO Policy (Nine minimum
controls).
Deep Tunnel System - A system of large diameter tunnels buried up to 120
feet under the rivers that are the main conveyance of sewage to ALCOSAN.
Direct Stream
Connections - Creeks and streams in municipalities that are captured in the sewage
system and conveyed to ALCOSAN rather than channeled to the river.
Driveway drain
- This drain channels water away from the driveway. On a driveway sloped toward the
house, the drain is frequently improperly connected to the sanitary sewer.
Dye Test - A tracer test
that is done to determine if downspouts or drains are connected to the sanitary
sewer.
Foundation
drain (also known as a French drain) - A drain installed around a home’s
foundation to prevent ground water from entering the basement. Water should be routed to
the stormwater system and not the sanitary sewer system.
House lateral - The pipe that conveys sewage from the house to the public
sewer system connection.
Infiltration - When water enters the sewer system through leakage such as a
cracked pipe. This can be caused by rainfall or by a high ground water table in the
soil.
Inflow - When water enters into
the sewer system through an opening such as a manhole lid or roof drain.
Interceptor
Sewer - Carries sewage from the trunk sewers to the treatment plant.
Long-Term Wet Weather Control Plan (LTCP) - A detailed plan required under
NPDES permits for combined sewer systems. The plan, which includes costly infrastructure
projects, must reduce overflows to only three or four wet weather events annually, and
must not impact water quality.
Manholes - Structures that are placed at changes in direction and elevations
of sewer systems. Manholes are used as access for cleaning the sewer system and other
maintenance activities.
Municipal
Satellite Collection System - The portion of the sewer that is owned by the
municipality. Excludes the house lateral. Carries sewage from many individual homes to
the trunk sewer.
Municipal
Separate Storm Sewer Systems (MS4) - A system designed to carry stormwater only.
MS4 systems will be regulated by the Stormwater Phase II regulations.
National Pollutant Discharge Elimination
System (NPDES) - A national permit system for all discharges to waterways.
Overflow Structures - Structures that
are designed to regulate sewage flows to the treatment plant by discharging excess flows
into the rivers.
Pump Station -
When a sewage connection cannot be made by gravity, this facility collects the sewage and
pumps it to an adjacent sewershed.
Retention or Storage Facility - A tank
that is built to store excess wet weather flows from sewer systems to prevent overflows.
The tanks are drained back to the treatment plant during dry weather.
Sanitary Sewer System - A system
that is designed to carry only sewage. Sanitary sewer system communities will be
obligated to meet standards outlined in the new SSO Rule (CMOM) in the very near
future.
Sanitary Sewer Overflows (SSOs) - When a sanitary or separate sewer is too
full due to inflow and infiltration, untreated sewage is discharged through overflowing
manholes and basement backups. This occurs primarily during wet weather, but can also
occur due to poor operation and maintenance.
Satellite
Treatment Facility - A small wet weather sewage treatment facility located at a
point of a combined sewer overflow to treat the sewage before discharging it to streams
and rivers.
Sewershed - A defined
area whose sewage or stormwater flows to a single point connection at a sewer interceptor
pipe or is tributary to a single pump station or treatment plant.
Sump pump - A system
typically installed in a homeowner's basement that collects water and pumps it into the
stormwater system to avoid wet basements. Sump pumps are frequently illegally connected
to the sanitary sewer system.
Trunk
Sewer - Carries sewage from multiple municipal collection systems to the
inceptor.
Watershed - A region or area bounded peripherally by a divide and draining
ultimately to a particular body of water.
Wye - The term for the point of
connection between the house lateral and the public sewer.
