Culverts are used to divert or drain water from land above higher up. They are enclosed watercourses and may be quite large. Responsibility to maintain a culvert is usually with the landowner for that part of it that is on the owner's land. There may be many culvert owners where the culvert passes beneath various land ownerships.
Blocked culverts can cause the water to back up and prevent it from draining the ground above, as intended and may also collapse. They may also contain toxic gases and are dangerous to go into. Knowing the identify of the land owners (or other land owners if you are one of them) over which a culvert runs will be of value to you in the event that the culvert becomes blocked and is or is likely to cause damage to your land, goods or local environment.
The search provides the following:
The Title Registers and Title Plans for the land specified by you, together with the land to the immediate North, South, East and West of your marked location. The Title Registers will provide you with the ownership details and the Title Plans will identify the extent of the land owned by the respective owner. The route of the Culvert below ground is not shown; the search is to identify ownership of the surrounding land only.
