Identify the authority to grant access
Tell us whether the building is a single property, a rented unit or part of an association. Identify any shared driveway, courtyard or locked utility area along the suspected route. Do not assume that ownership of a unit includes control of the entire supply line.
Have the property manager or owner confirm who may approve investigation and any later opening. This avoids arriving at a location where the necessary access cannot lawfully be given.

Use records for orientation, not diagnosis
Southgate records service connections at the main and their alignment. If it is the district for the address, existing connection information may help frame a route question. Private alterations may also be documented in property records.
A drawing indicates an intended or recorded route. It does not prove that water on a driveway came from that pipe or show its present condition. Ask how the investigation will distinguish route confirmation from leak confirmation.
Protect the surface and what is below it
Keep traffic away from visibly washed-out or unstable areas and report a public-access hazard to the appropriate authority. Avoid exploratory drilling or breaking pavement. The repair plan must account for underground utilities as well as the suspected water line.
An ordinary 811 request does not include every private service or irrigation line. Ask who will coordinate required notification, response checks and private locating before any excavation is allowed.
Review disruption as part of the decision
Before approving work, ask about utility shutoff coordination, access for occupants and temporary protection of an opening. Separate pipe work from reinstating pavement, landscaping or shared surfaces. Call us with the address and who can authorize access to confirm what initial investigation is available; repair logistics should follow evidence.
Reference notes
Local boundaries and technical guidance have limits. Check the address and the current requirements with the relevant authority.
