Sewer asset types
Note: The asset types that are available to you depend on your access rights and on the asset products that your agency has purchased.
| Asset type | Special features |
|---|---|
| Backflow preventer | Several fields indicate structural information about the backflow preventer, such as its size and pressure zone. Other fields indicate the main and service line that the preventer is associated with. Backflow preventers are attached to service lines and are used to prevent the accidental backflow of wastewater run-off into buildings. |
| Lift station | Use the grid to list the assets that are connected to the lift station, such as the nearest manhole or sewer node. Several fields indicate structural information about the station, such as wet well and pump dimensions. The Main fields indicate the main that the station is connected to. Lift stations are pumping devices that raise wastewater from areas that are too low to drain into existing mains. Use the Components tab to define components of the lift station that can be inspected separately. |
| Main | The Main ID and To fields indicate the assets at each end of the main, such as a node and a manhole. The # field indicates the main's line number if any other mains have the same beginning and ending assets. Use the grid to list the assets that are connected to the main, such as service lines or lift stations. Several fields indicate structural information about the main, such as its slope, design flow, and the elevation of its upstream and downstream ends. Sewer mains are pipes or conduits that receive wastewater from multiple tributaries, such as service lines, and direct the wastewater toward a treatment plant or other suitable outlet. |
| Manhole | Use the grid to list the assets that are connected to the manhole, such as a main or service line. Several elements indicate structural information about the manhole, such as its surface cover, its dimensions, and whether it is a drop manhole. |
| Meter | The Position field shows the meter's position at the address. The position cannot exceed the maximum number of positions allowed for sewer meters at the address, and a position of 0 indicates that the meter is not in use. Several elements indicate structural information about the meter, such as its size, the type of pipe connected to it, and whether a bypass is installed on it. The Register field indicates a single register or a single dual register associated with the meter. If the meter uses two single registers, the Register field is replaced by two fields: High Register for the register that measures high volumes of flow, and Low Register for the one that measures low volumes of flow. The Meter Component field indicates a component, such as a summator, associated with the meter. Use the grid to record data from the meter's name plate, such as its model and manufacturer. Use the grid to record a performance reading of the meter, such as a reading of its average flow rate. Other fields indicate the main and service line that the meter is connected to. Use the grid in the InfoViewer to record a meter reading. If your agency uses register and component records to track subparts, the meter record identifies the main body of the meter, which uses cylinders, rotors, or gears to measure the flow of wastewater. Sewer meter records can also be used to track entire meter structures, without separate records for the registers and components. |
| Meter component | A meter component is any supplemental piece of equipment attached to a meter, such as an Encoder Receiver Transmitter (ERT) that reads the meter register and transmits the reading to a handheld device. The Position field shows the component's position at the address. The position cannot exceed the maximum number of positions allowed for sewer meter components at the address, and a position of 0 indicates that the component is not in use. The Master Component fields indicate the parent sewer asset that the meter is associated with, such as a summator that combines readings from several meters. Use the grid to record data from the component's name plate, such as its model and manufacturer. Use the grid to record a performance reading of the component, such as noting the degree of over-registering or under-registering revealed during a test of a summator. The and grids in the InfoViewer list any meters and other components associated with the current component. |
| Meter register | A meter register is the part of the meter that records and shows the usage amount. The Position field shows the register's position at the address. The position cannot exceed the maximum number of positions allowed for sewer meter registers at the address, and a position of 0 indicates that the register is not in use. Use the grid to record data from the register's name plate, such as its model and manufacturer. Use the grid to record a performance reading for the register, such as noting the degree of over-registering or under-registering revealed during a test of the associated meter. The and grids in the InfoViewer list any meters and components associated with the current register. |
| Miscellaneous | Use the grid to associate other assets with the miscellaneous asset, such as the nearest manhole or sewer node. Use the grid to record data from the asset's name plate. Several fields indicate structural information about the asset. Other fields indicate the main and service line that the asset is associated with. A miscellaneous asset is an asset that does not fall under any of the existing sewer asset types, such as a chemical storage unit, internal combustion engine, or outfall weir. |
| Node | Several fields identify the specific node and indicate the main that it is connected to. A node is an attribute of a pipe, such as a joint or change in pipe diameter. It can be used to identify the endpoint of a main. |
| Pump | The Position field shows the pump's position at the address. The position cannot exceed the maximum number of positions allowed for sewer pumps at the address, and a position of 0 indicates that the pump is not in use. Several fields indicate structural information about the pump, such as the size of its discharge opening, its flow rate, and its average revolutions per minute (RPM). The Main fields indicate the main that the pump is connected to. Use the grid to record data from the pump's name plate, such as its model, motor type, and voltage. Use the grid to record a performance reading for the pump, such as a reading of its average RPM or flow rate. Use the grid in the InfoViewer to record the pump's usage. |
| Service line | Use the grid to list the assets that are connected to the service line, such as a backflow preventer or building. Several fields indicate structural information about the service line, such as its pipe type and dimensions. Other fields indicate the main that the line is connected to and the specific address of its tap. A service line is a gravity-flow pipeline connecting a building's direct runoff collection system to a sewer main. |
| Treatment plant | Use the grid to associate other assets with the plant, such as a complex that the plant is a part of or a service line that is connected to it. Use the Components tab to define components of the plant that can be inspected separately. |
| Valve | The Position field shows the valve's position at the address. The position cannot exceed the maximum number of positions allowed for sewer valves at the address, and a position of 0 indicates that the valve is not in use. Several fields indicate structural information about the valve, such as its pressure zone and size. Other fields indicate the main and service line that the valve is associated with. Use the grid to list data from the valve's name plate, such as its model and manufacturer. Use the grid to record a performance reading for the valve, such as a reading of its average flow rate. Use the grid in the InfoViewer to record the valve's usage. |
