Description: Are not shown at scales smaller than 1:2,400. In some cases even at 1:100 scale, meter symbols will overlap one another. This is partly due to automated methods for creating meter features at the ends of laterals, particularly based on automated methods for creating laterals off of mains. Ideally meter features are located as precisely as possible relative to their real-world locations—in practice this is expensive without using GPS, which doesn’t deal with the lateral locations. In this map, meters, are not the focus and therefore are not labeled—in a meter management map labels would be necessary.
Description: Hydrants are shown from 1:4,800 to larger scales. These symbols are based on a hydrant symbol has been common on engineering drawings for decades. These symbols are rotated to depict the orientation of the valves. Starting at 1:2,400 hydrants are labeled with their asset ID.
Description: Control valves are shown from 1:4,800 to larger scales. The symbol for control valves may be rotated or changed to reflect the type of valve (butterfly, ball, etc.), or a box symbol may also be added when these values are installed within a box. The difference between control valves and system valves is that control valves have a backflow prevention control. Control valves are labeled at scales from 1:1,200 and larger with their asset ID.

Description: System valves are shown from 1:4,800 to larger scales. System valves are labeled at scales from 1:1,600 and larger with their asset ID. The symbols for system valves are expected to vary from utility to utility—these are some typical symbols, but by no means do they represent an accepted standard.
Description: Fittings are shown at scales larger than 1:4,800, though are not labeled in this general depiction of the water network—users would be expected to click on the fittings to get more information.
Description: System valves are shown from 1:4,800 to larger scales. System valves are labeled at scales from 1:1,600 and larger with their asset ID. The symbols for system valves are expected to vary from utility to utility—these are some typical symbols, but by no means do they represent an accepted standard.
Description: The symbology for the water mains divides the largest mains (14” and larger) from the smaller mains (12” and smaller), but also graduates the symbols so that some relative differences can be seen. At scales 1:4,800 and 1:2,400 the longer mains are labeled, and at 1:2,400 short mains are labeled with leader lines. At 1:1,600 the longer mains have a more prominent label, allowing for clear reading at all large scales, while the same becomes true for the shorter mains at 1:800.

Description: Lateral lines are shown from 1:2,400 to larger scales and this is in conjunction with the meters—as the lateral lines connect meters to mains. These features are not labeled.
