Drainage compliance audits compare the drainage system with the evidence needed for a defined site review. We examine the agreed drawings, discharge arrangements and maintenance findings, then explain the gaps. A camera survey can show a damaged pipe, but it cannot by itself establish that the liquids entering it have permission to be discharged.
Drainage Compliance Audits
Drainage compliance audits reviewing defined drainage evidence, discharge routes, maintenance gaps and the follow-up evidence still needed.

Discharge routes and supporting evidence
The audit connects current site activity to the actual drainage route.
Reviewing evidence against the audit purpose
The review is tied to the reason for the audit, such as a facilities check or a question raised by a regulator.
Discharge routes and supporting evidence
The audit connects current site activity to the actual drainage route. Altered production areas can leave old drawings inaccurate. Trade effluent, foul drainage and surface-water discharge may be subject to different controls. We distinguish a confirmed connection from an assumption, and identify where tracing or sampling is needed before drawing a conclusion.

Reviewing evidence against the audit purpose
The review is tied to the reason for the audit, such as a facilities check or a question raised by a regulator. We compare available maintenance information, accessible condition evidence and relevant discharge permissions. Missing evidence stays identified as missing rather than being replaced by a general statement that the drainage appears satisfactory.
Audit findings and follow-up actions
The findings separate what has been established from what still needs investigation. An audit can identify a maintenance gap, uncertain connection or evidence problem, but it does not grant a permit or certify every aspect of legal compliance. Any permission or change to a discharge remains a matter for the relevant authority.
An uncertain connection may need tracing or sampling. A separator service gap needs maintenance evidence specific to that unit.
Drainage Compliance Audits: common questions
Does a CCTV survey prove environmental compliance?
No. CCTV shows inspected pipe condition, not every discharge or operating obligation.
Can an audit grant a discharge permit?
No. The relevant authority grants discharge permissions.
What should follow an uncertain connection finding?
The route needs a defined investigation before the audit can reach a firm conclusion.
Can old drawings be relied on without checks?
They need comparison with current site activity and any changes to connections.
Will the audit identify missing evidence?
Yes. Gaps and the work needed to resolve them are made explicit.
