Who supplies water and who runs the sewer in Dana Point
The city's utilities page says water is provided by two independent special districts, South Coast Water District and Moulton Niguel Water District, and that the district boundaries map shows which one serves a given property. Your bill is the quickest way to know.
The same page says the sewer system is owned, operated and maintained by South Coast Water District. So a sewer concern in Dana Point goes to that district, whichever district supplies your water.
Nothing found for this page says where South Coast's responsibility for a lateral ends, so none is claimed. A call to the district before paying for a repair is worth the few minutes.
What was checked
The city's utilities page names both water districts and the sewer owner. It does not say which district serves which streets.

Hydro jetting and drain work in Dana Point
Hydro jetting is useful when a line is coated with grease or scale, and a cable is useful when the blockage is a soft plug or roots. Which one is used depends on what the first cable pass meets. A camera shows the rest.
Before a jet is run, the plumber should confirm the pipe can take the pressure. Old or cracked clay and cast iron can be damaged, which is one more reason a camera look comes first on an older line.
A question worth asking before any cleaning is whether the plumber will camera the line afterward. A pipe can be clear and still cracked, and then the blockage returns; the footage is the evidence. The drain cleaning page describes each method.
Leak detection in Dana Point homes
A leak you cannot see announces itself through the meter, the bill or a damp spot. To confirm one, turn everything off and watch the meter's small dial. If it moves, close the house valve and watch again. The result tells you which side of the valve the leak is on. Photograph the meter, the damp area and any stained ceiling, and write down the times, so that the plumber and, if needed, the district see the same evidence.
A locator then narrows the position so that any digging is small. Ask for the findings in writing: location, depth if known, pipe material and the repair method proposed. The leak detection page explains the tests.

Slab leaks in Dana Point: finding the line under the floor
A warm patch on a floor, the sound of water in a quiet house or a meter that moves with nothing running can all signal a slab leak, though each has other causes. Electronic listening and pressure testing identify the likely line before the slab is touched.
From there, three options exist: break through at the leak, reroute through walls or ceiling, or replace the supply system. Each moves the damage somewhere else. Decide by what you would rather repair, and put the permit and patching in the written scope. Expect the plumber to explain how the leak was confirmed before any cutting is priced. The slab leak page compares them.
Water damage cleanup in Dana Point
Once a leak has soaked drywall and flooring, the water is pulled out, the structure dried and moisture readings repeated until they drop. Ask for readings, not guesses.
Move valuables and rugs out of the wet area, switch off power to wet outlets and take photographs from several angles. Cleanup crews will ask when the leak began and when it was stopped, so jot those times down while they are fresh.
Keep photographs of the damage before cleanup begins and a note of what caused it. An insurer asks for both. The water damage restoration page lists the stages.
The restoration number differs from the main one, and that page displays it.
Water heater repair in Dana Point, and the city's permit rule
Dana Point's water heater handout says that all water heater installations and replacements require a permit and a final inspection, citing the plumbing code. It adds that a tankless unit cannot be handled as a mail-in permit and goes through a review instead. Ask any installer to confirm the permit is pulled and the inspection booked.
Repairs are different. A pilot assembly, a thermostat, an element or a relief valve can be replaced without a new tank. A shell that leaks cannot be repaired. The water heater repair page helps you decide.
The city's rule in short
A permit and a final inspection for every water heater installation or replacement; tankless units are reviewed.
