Abstract

A survey monument comprises a conventional water hydrant with survey indicia or markings attached thereto. The survey indicia can be carried for example on a plate mounted on a flange bolt or attached to the operating nut of the hydrant. These survey monuments can be expanded upon and/or maintained in co-ordination with the expansion and maintenance of a municipality'"'"'s water supply system. The hydrants can also be utilized in connection with any geographical information system to provide known reference points. The hydrants can also be utlized in connection with GPS devices to assist in localizing, initializing and calibrating the same.

Claims

1. A water hydrant comprising:

(a) a vertically upstanding barrel section adapted for fluid communication with a water source;

(b) at least one water outlet adapted for fluid communication with said barrel section; and

(c) a survey element positioned on said water hydrant, said survey element comprising survey indicia, said survey indicia being related to information defining the location of a reference point on said hydrant in two dimensional space.

2. A water hydrant as claimed in claim 1 wherein said survey element has said survey indicia visibly marked thereon.

3. A water hydrant as claimed in claimed in claim 2 wherein hydrant further comprises an operating nut interconnected to a valve mans, for controlling the flow of water in said barrel section, and wherein said survey indicia are located on a visible surface of said operating nut.

4. A water hydrant as claimed in claim 2 wherein said survey element comprises a monument plate and said survey indicia are located on said monument plate which is visibly mounted on said hydrant.

5. A water hydrant as claimed in claim 4, wherein said barrel section has a peripheral flange circumscribing a lower portion of said barrel section, said flange having flange bolts for interconnecting said barrel section to a pipe carrying water from a water main, to provide for fluid communication between said pipe and said barrel section, and wherein said monument plate is mounted on to said flange.

6. A water hydrant as claimed in claim 5 wherein said monument plate is interconnected to one of said flange bolts.

7. A hydrant as claimed in claim 1 wherein said information defines said location in three-dimensional space.

8. A hydrant as claimed in claim 1 wherein said reference point is on said survey element.

9. A hydrant comprising:

a vertically upstanding pipe section having an inlet and at least one outlet, said inlet and outlet interconnected by an interior conduit, said inlet being adapted to be connected to a water source for fluid communication with said water source;

a survey element positioned on said water hydrant, said survey element comprising survey indicia, said survey indicia being related to information defining the location of a reference point on said hydrant in two dimensional space.

10. A hydrant as claimed in claim 9 wherein said information defines said location in three-dimensional space.

11. A water hydrant as claimed in claimed in claim 10 wherein hydrant comprises an operating nut interconnected to a valve means, for controlling the flow of water in said pipe section, and wherein said survey element is secured to a surface of said operating nut.

12. A hydrant as claimed in claim 9 wherein said reference point is on said survey element.

13. A hydrant as claimed in claim 12 wherein said hydrant is in fluid communication with said water source.

14. A hydrant as claimed in claim 13 wherein said water source is part of a multi-hydrant water distribution system.

15. A water hydrant as claimed in claimed in claim 14 wherein hydrant further comprises an operating nut interconnected to a valve means, for controlling the flow of water in said pipe section, and wherein said survey indicia are located on a surface of said operating nut.

16. A water hydrant as claimed in claim 15 wherein said survey indicia are located on a monument plate mounted on said hydrant.
