Define pumping
Ask which tank or chamber is accessed, what is removed, how volume and condition observations are recorded, and what is outside scope.
Visit-scope matrix
Distinguish pumping, component maintenance and performance assessment by purpose, access, observations, tests, reports and limits.
Decision file
Ask which tank or chamber is accessed, what is removed, how volume and condition observations are recorded, and what is outside scope.
Use the actual system and maintenance plan to identify component checks, cleaning, controls, alarms and records. Avoid a universal schedule.
State the property decision and request an assessment scope, methods, accessible components, operating conditions, limitations and report output.
Confirm lids, risers, electrical controls, vegetation, vehicles, pets and ground conditions without asking occupants to expose or enter components.
Ask why a sample or test is relevant, who interprets it and what it cannot conclude. Avoid health or environmental guarantees.
Require a dated service record, components visited, work performed, observations, limitations, follow-up and filing implications if any.
State whether the immediate need is routine tank service, component maintenance, symptom investigation, transaction evidence or planning for increased use. Require the proposed visit to list the components accessed, observations made and questions it cannot answer.
Ask who safely locates and opens components, what liquid levels or equipment conditions are documented, how material is handled and which operating observations occur before or after service. Owners should not enter, open or manipulate system components.
A pumping receipt does not establish system condition, capacity or transaction suitability. Require written findings, limitations, maintenance recommendations, repair questions and the trigger for authorized-person, health-authority or other project-specific review.
Before booking, state whether the visit addresses routine service, component maintenance, a symptom, transaction evidence or future project planning. North Cowichan explains that pumping timing depends on tank size, waste volume and composition, weather and system type; record those property facts instead of assuming one interval fits every home. List components expected to be located or accessed, observations or tests proposed, material handling and the written output. Ask whether the visit is limited to pumping or also includes maintenance or assessment, and which findings will be documented. The BC Sewerage System Regulation requires an owner to operate and maintain the system in accordance with its maintenance plan and to keep maintenance records. Afterward, reconcile actual access, work, findings, limitations, disposal or service documentation and follow-up questions. Note components that could not be accessed and advice that still needs an Authorized Person. Add the invoice, dated service record, observed liquid or component notes and any maintenance-plan update to the same property file. Record recommendations using the provider’s wording and identify who is qualified to decide the follow-up. Keep pumping, maintenance and performance-assessment conclusions separate. A complete visit record helps plan the next decision, but a receipt alone does not establish system capacity, condition, filing status, remaining life or suitability for a sale.
