A completed 811 ticket may leave the well lines unresolved
Before ground disturbance near a private well, resolve both the applicable one-call notification and the separate locating needs of owner-maintained facilities. Ask explicitly about the well water pipe, electricity supplying the pump and nearby septic components. A response from a participating utility does not establish that every private facility was included. Do not let a crew interpret an empty patch of lawn as confirmation that there is nothing below it.
This guide concerns an existing owner planning a specific project, not a buyer estimating purchase risk or an owner tracing an active leak. Alaska811 expressly lists private and community well water lines and septic-system sewer lines as examples of private facilities. Ohio811 also identifies homeowner lines outside the ordinary member-utility scope. Their explanations support the scope distinction; their state deadlines, exceptions and excavation rules are not nationwide instructions.
Draw the actual disturbance area, not just the finished feature
Describe the proposed work to the excavator and the relevant notification service before choosing a start date. Include the areas affected by posts, trenching, stump removal, grading and temporary construction activity. A line clear of the finished fence may still conflict with its postholes or equipment route. Have the contractor explain the work footprint rather than assuming that a sketch of the final structure describes every disturbance.
Use known landmarks and available site records to communicate the location. Label a homeowner sketch as approximate; do not draw a straight line between the wellhead and house and present it as a locate. Ask which party submits and maintains the required notification for the actual work. A prior ticket for another project or another contractor is not automatically the right notification for this project.
Split the onsite system into separate questions
A well supplies water through piping, but its pump also requires an electrical supply. Identify both as separate scope items when asking a private locator or qualified well provider what can be located. State what records exist and what remains unknown. A contractor accepting a water-pipe assignment may not have accepted the pump-power assignment; obtain an explicit answer rather than letting the word well stand for everything.
Also identify the tank, building sewer, drainfield, distribution or dosing components and any unused facilities shown in septic records. Finding a tank lid does not establish every connecting route. The septic-tank location guide helps with that narrower records question. For excavation planning, ask the septic professional which components intersect the work area and what verification remains necessary. Do not open tanks, probe blindly or enter a confined space.
Collect records without treating them as current measurements
Gather well construction information, pump replacement invoices, septic permits, as-built drawings and previous locating reports. Note later additions such as an outbuilding, relocated pressure equipment or a changed driveway. Give copies to the provider and retain originals. Ask whether a drawing represents proposed installation, completed work or an approximate recollection; these are different kinds of evidence even when all appear in the same property folder.
Virginia811 points owners toward local health-department records for septic layouts and toward private locating contractors for owner lines. Availability varies with location and property age. Missing records are an unresolved task, not proof that a line is absent. If records conflict with visible equipment, flag the conflict before scheduling disturbance. Do not resolve it by selecting whichever drawing makes the planned work easiest.
Ask what the private locating service will actually deliver
Request a written scope naming each facility, the project area, any accessible connection points the provider needs, and the form of the report or markings. Ask how limitations and unsuccessful searches will be communicated. Do not assume a particular instrument can locate every pipe material, disconnected line or abandoned component. The provider should explain its method and limitations for the actual site without an owner attempting to attach equipment to electrical or water-system components.
A useful quotation distinguishes the initial survey from any additional professional verification needed to resolve uncertainty. Ask who coordinates the well contractor, electrician or septic provider if one service cannot finish the scope. Keep permission to access equipment and responsibility for protecting the work area explicit. This is a coordination checklist, not a recommendation to perform test excavation or expose buried services yourself.
Review a completion matrix with the excavator
Read the matrix as a set of separate gates, not a way to add up reassurance. The owner and excavator should know which question each report answers. A provider response saying no conflict for its own facility does not answer the row for another facility. Keep unresolved items visible in the work order instead of burying them in an email attachment nobody at the site has read.
| Scope | Evidence to request | Unresolved condition |
|---|---|---|
| Member utilities | Applicable ticket and actual operator responses | A response missing or inconsistent with site evidence |
| Well water pipe | Private provider scope and documented result | Unknown route, material or incomplete search |
| Pump electrical supply | Qualified identification and locating result | Water line marked but power not addressed |
| Septic components | System records and appropriate professional verification | Tank found but field or connecting routes uncertain |
| Changed work footprint | Reconfirmed notification and private scope | Crew plans work outside the reviewed area |
Use local rules and stop when the evidence does not fit
Confirm current notice periods, ticket validity, response requirements, marking protection and excavation practices with the applicable state service and qualified excavator. This article provides no universal waiting period, tolerance zone, burial depth or safe digging method. If marks disappear, the scope changes or an apparent facility is unmarked, postpone the affected work and use the proper clarification process. A contractor schedule does not resolve an incomplete locate.
Keep vehicles and construction loads away from septic components under the site plan. If damage, an exposed cable, escaping gas, sewage or another immediate hazard is encountered, stop and move away to obtain the appropriate emergency help. Do not touch, investigate or repair a struck facility. The buried well-line leak guide addresses a different service concern, not permission to excavate a suspected route.
Illustrative scenario: the fence crew sees only one set of marks
Imagine a homeowner plans new fence posts between a well and the house. The utility response addresses the service supplying the house, but nobody has established the pump cable or well-pipe route. This is an illustrative planning example, not an actual locate. The owner pauses the affected posts, gives the private provider the pump and septic records, and requests separate written results for each onsite facility.
If the provider cannot resolve one route, the next step is a defined professional investigation or a reviewed project change, not a guess that the pipe probably follows the shortest path. At handoff, the excavator receives the applicable notification status, private results and limitations for the same footprint. The outcome is a coordinated start decision with explicit gaps closed; no document becomes a promise that excavation is risk-free.
Frequently asked questions
Does 811 replace private locating? Not necessarily; establish which facilities its participating operators address. Does knowing the wellhead location establish the pipe route? No. Does locating the pipe identify the pump power cable? Confirm that separate scope. Is a permit drawing a current field locate? Do not treat it as one. Can this guide supply a safe digging depth? No; site conditions and applicable rules require qualified review. What if a provider cannot locate a component? Keep the work paused in that affected area until the responsible professionals resolve the uncertainty.
