Define the proposed change
Record bedrooms or occupancy, fixture or use changes, additions, suites, business use, repair concern or replacement goal without estimating capacity yourself.
Change-project route
Connect proposed occupancy or flow changes, system evidence, site and water constraints, qualified roles, filings, construction and maintenance records.
Decision file
Record bedrooms or occupancy, fixture or use changes, additions, suites, business use, repair concern or replacement goal without estimating capacity yourself.
Compare plans and filings to known site components and service history. List discrepancies for qualified review.
Existing or proposed capacity, treatment, dispersal and suitability require project-specific assessment and authorized design decisions.
Document known wells, waterways, slopes, drainage, property boundaries, structures, access and planned grading for current setback verification.
Ask which authorized person, engineer, installer, maintenance provider, health or local authority steps apply and what each supplies.
Compare inspection, record drawings, filing evidence, commissioning, owner information and updated maintenance plan.
List bedrooms or occupancy changes, suite plans, fixtures, appliances, business use and construction sequence without declaring design flow. Provide the same project description to the authorized person and reviewing authorities.
Place buildings, wells, watercourses, slopes, property lines, access, utilities and known system components on one plan. Identify survey or field evidence still required and keep construction traffic away from protected system areas.
Assign assessment, design, health-authority filing, construction, inspection, commissioning and maintenance-record responsibilities for the selected project. Keep approved revisions, material or component changes, photographs and owner instructions in the property system file.
Combine the proposed occupancy and fixture changes, existing filings, verified system map, site and water constraints, qualified assessment or design inputs, authority route and construction sequence. North Cowichan notes that a new home, mobile home or bedroom addition on a property without municipal sewer may require Island Health documentation, and its building process may require a record of sewage or letter of certification. Island Health explains that constructing or repairing a system requires an Authorized Person and the applicable filing. Confirm the current route for the actual property before design or excavation begins. Identify investigation and approval hold points before equipment, traffic or building work affects known or probable system areas. Share the same dated project description with the designer, builder and permitting contacts so bedroom, occupancy or use assumptions do not drift between documents. Protect mapped treatment and dispersal areas from stockpiles and vehicle access, including during demolition and material delivery. During work, record revisions, component information, inspections, commissioning and restoration. The BC regulation requires specified filing and certification records, including a maintenance plan, to be provided to the owner. Finish with those documents, an updated component map and maintenance instructions. This control file coordinates a project-specific process and must not present an owner’s room count, tank label or old plan as proof of design flow, remaining capacity, setback compliance or approval.
