Sewage Treatment Process Guarantee Test Not Approved Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the sewage treatment process guarantee test, process-guarantee acceptance report, or treatment-performance signoff still lacks approval. This page is for treatment projects where the missing item is the guaranteed performance proof of the process itself, not a minor punch-list issue. The commercial problem is that the plant may already be operating, but the payer is still withholding the final balance until the guarantee-test evidence is accepted. Your email should ask whether the guarantee test is the only blocker left, whether the latest test run has already been completed, what treatment parameter, loading condition, or acceptance criterion remains unresolved, and whether payment will be released once the report is approved. The result you want is a specific release condition tied to one exact process-performance deliverable.
