Code value |
| LL |
Lateral line.
-- Description --
A <i>lateral line </i>is a small-diameter pipe that runs from the main line to the customer premises.
|
|
| LL_Combination |
Lateral line that transports a combination of sanitary and storm water.
-- Description --
Lateral line that transports a combination of sanitary and storm water.
|
|
| LL_Commercial |
Lateral line that transport commercial-origin wastewater.
-- Description --
Lateral line that transport wastewater from commercial facilities.
|
|
| LL_Domestic |
Lateral line that transports domestic sanitary water.
-- Description --
Lateral line that transports domestic wastewater.
|
|
| LL_Irrigation |
Irrigation lateral line.
-- Description --
Lateral line that transports irrigation wastewater.
|
|
| LL_Storm |
Lateral line that transports storm water.
-- Description --
Lateral line that transports storm water.
|
|
| ML |
Main line.
-- Description --
A <i>main line </i>is a large-diameter pipe that carries sewer from the source through the network.
|
|
| ML_GM |
Main line's gravity main.
-- Description --
A <i>gravity main </i>is a type of main line that is unpressurized and relies on gravity to move the water through the main.
|
|
| ML_GM_Collector |
Main line's gravity main's collector.
-- Description --
A <i>collector </i>is a pipe that collects and transports wastewater to a treatment plant or disposal system. Service laterals connect to collectors.
|
|
| ML_GM_Culvert |
Main line's gravity main's culvert.
-- Description --
A <i>culvert </i>is a pipe used to channel water e.g. underneath a road, railway or embankment.
|
|
| ML_GM_InLineStorage |
Main line's gravity main's in-line storage.
-- Description --
<i>In-</i><i>l</i><i>ine storage</i> involves retaining wet-weather flow in the pipe for small rainstorms.
|
|
| ML_GM_Interceptor |
Main line's gravity main's interceptor.
-- Description --
Large sewer line that controls the flow of sewage to the treatment plant. In a storm it allows some of the sewage to flow directly into a receiving stream, thus keeping it from overflowing onto the streets.
|
|
| ML_GM_InvertedSiphon |
Main line's gravity main's inverted siphon.
-- Description --
An <i>inverted siphon</i> is a pipe that must dip below an obstruction to form a „U“ shaped flow path. Inverted siphons are commonly used for preventing smelly sewer gases from coming back out of drains.
|
|
| ML_GM_OpenChannel |
Main line's gravity main's open channel.
-- Description --
An <i>open channel</i> is a channel open to the environment that transmits raw water and drainage.
|
|
| ML_GM_Outfall |
Main line's gravity main's outfall.
-- Description --
<i>Outfalls </i>are the conduit leading to the final disposal point or area for wastewater and drainage. Outfalls discharge into a receiving water body, such as a stream, river, lake, ocean, or other surface, or groundwater.
|
|
| ML_GM_Overflow |
Main line's gravity main's overflow.
-- Description --
An overflow connects a chamber or pipe to another part of the system or outfall during overload conditions or peak flows.
|
|
| ML_GM_Tunnel |
Main line's gravity main's tunnel.
-- Description --
Tunnels are used to transmit sewer through mountains or deep below the ground. Tunnels are generally created in bedrock and may contain features such as pipes and ducts (conduits) within the tunnel.
|
|
| ML_PM |
Main line's pressurized main.
-- Description --
A <i>pressurized main </i>is a type of main line that is pressurized. Pressure sewers are particularly adaptable for rural or
semi-rural communities where public contact with
effluent from failing drain fields presents a substantial
health concern.
NOTE There are numerous types of PressurizedMains in the sewer distribution model; they include AirRelease, BlowOff, Bypass, ChemicalInjection, DistributionMain, Interconnect, PipeBridge, SamplingStation, and TransmissionMain.
|
|
| ML_PM_ForceMain |
Main line's pressurized main's force main.
|
|
| ML_PM_PipeBridge |
Main line's pressurized main's pipe bridge.
|
|
| ML_PM_Pressure |
Main line's pressurized main's pressure.
|
|
| ML_PM_Vacuum |
Main line's pressurized main's vacuum.
