Drainage test record builder

Use one record for one defined test event

An inspection and test plan states what the project intends to check. This worksheet records an individual event: the asset, the method used, what was observed and the evidence supporting the review. It can also document a test that was not started or was aborted. Do not mark a test completed merely because the form contains text.

Identify the tested limits using controlled drawing references and revisions. A result for one section does not establish the condition of an untested branch, connection or adjoining run. State exclusions and deviations so the reviewer can understand the limits of the record.

Keep criteria, readings and decisions separate

Criteria are the project requirements against which results are reviewed. Readings are the actual measured values or observations, with their units and timing. The reviewer decision is a separate entry linked to the person or role with the appropriate authority. The builder performs no technical comparison between those entries.

Add a reading for each relevant parameter or observation. Reference the original instrument output, report or photograph in the evidence index. Entering a file location does not attach the file: retain the originals in the controlled project record system.

Preserve the first result when retesting

If corrective work or a repeat test is needed, keep the original event and its decision. Start a separate record for the retest, linking the previous reference and any non-conformance record. A non-conformance record documents a departure from specified requirements and the actions taken to address it. Do not overwrite an earlier failed or incomplete result with a later one.

Download a text copy, print the current record or use the browser's Save as PDF option. Review the output before filing it, especially the asset limits, units, unentered fields and unresolved actions. The document remains an unsigned working record, not an authenticated certificate.

Sources and limits

• Water UK Sewerage Sector Guidance, Appendix C, approved version 2.3 (11 November 2023) concerns foul and surface water sewers offered for adoption under the Code for adoption agreements for water and sewerage companies operating wholly or mainly in England. Its testing requirements are not universal rules for every private drain. Confirm the applicable documents, revisions and undertaker requirements for the actual project.
• HSE introduction to confined spaces explains avoiding entry where possible and the need for assessed controls and emergency arrangements where entry is necessary. This record does not authorise chamber entry or establish that it is safe.
