01
Define the cleaning scope
Identify each tank by capacity, material and location and provide access dimensions and photographs. Inspection should establish the reachable areas and the conditions needed for the work. Do not assume that every tank needs or permits the same access procedure.
- Tanks identified by location, construction and access
- Cleaning sequence and water-service interruption agreed after inspection
- Worksite cleanup and documented handover
02
Inspect the site and plan access
Name the parties responsible for isolation, drainage, refilling and return to service. If entry is required, the site-specific access and safety process must be approved before work. This page does not prescribe an entry method or establish that any particular tank is safe to enter.
- Tank dimensions, construction, condition and access
- Drainage, isolation and water-service continuity ownership
- Entry requirements and the approved site safety process
03
Agree equipment and treatment
Cleaning and removal equipment are selected against the inspected tank and agreed method. Testing or treatment must be expressly defined where requested. Repair, lining replacement and structural remediation need a separate scope; they should not be represented as an automatic part of cleaning.
- Equipment selected for actual tank access and condition
- Cleaning and removal tools included in the reviewed method
- Testing or treatment only when expressly defined and verified
04
Confirm exclusions before approval
Resolve the following boundaries during scope review and record them in the quotation. They are points to agree for the actual site, rather than a substitute for the final contract terms.
- Entry without an approved access and safety plan
- Tank repair, lining replacement and structural remediation
- Potability, laboratory or health certification without verified testing scope
05
Prepare the quotation inputs
Send the location and task information below with the proposed work window. The reviewed quotation should identify included areas, equipment and supervision, access dependencies, commercial terms and information still needed. Prices and completion dates are agreed from the inspected scope.
- Number, capacity, material and location of tanks
- Access dimensions and photos
- Permitted service interruption and drainage arrangements
- Isolation and refilling owner
06
Inspect completion and record exceptions
The handover should record completed cleaning, condition observations, inaccessible areas and defects referred to the owner. Document return-to-service ownership. Potability, laboratory or health certification requires a separately verified testing and certification scope and cannot be inferred from cleaning completion.
- Cleaning completion and condition observations recorded
- Exceptions or defects referred to the tank owner
- Return-to-service responsibility documented
07
Keep a tank-by-tank record for the service enquiry
Give each requested tank a reference linked to its building and location. Record the owner-provided construction, capacity, access information and condition observations relevant to the scope review. Identify which items still need inspection or clarification. This lets the response distinguish confirmed cleaning tasks from unanswered site questions rather than apply one assumed requirement to every tank.
For several tanks or buildings, use the same references in the reviewed quotation and work sequence. A changed location, access dependency or requested task should identify the affected tank and the contact responsible for the next decision. Keep the current record available to the employer coordinator and cleaning supervisor before workforce and resource arrangements are confirmed.
08
Coordinate the proposed window with building operations
Name the employer contact coordinating the service window and the responsible owners for the operational arrangements already identified in the inspected scope. Record the proposed timing by tank and the decisions still required before the cleaning team receives its assignment. Keep a planned window separate from confirmation that all receiving arrangements are ready.
Where several buildings share one programme, identify the tank references and operating contacts for each stage. Review changed timing against the affected scope, resources and dependencies. The employer coordinator should be able to see who confirms the next arrangement rather than infer readiness from a single programme date or a proposed worker quantity.
09
Link workforce coordination to the tank handover record
State the task groups, supervision and agreed resources for the reviewed assignment. The receiving supervisor needs the current tank references, instructions and unresolved dependencies. Record changes through the employer coordination route so the team follows the confirmed scope for the actual location and period rather than an earlier version of the enquiry.
Use the same tank references when recording completed cleaning, observations and outstanding actions. Identify the employer contact receiving the handover and the next owner for each unresolved item. Keep cleaning completion distinguishable from separate repair, testing or certification decisions. The record supports workforce and service coordination within the existing scope described on this page.
