Sludge Dewatering Performance Test Not Approved Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the sludge dewatering performance test, dewatering acceptance report, or sludge-performance signoff still lacks approval. This page is for wastewater or industrial-treatment projects where the blocker is the proven output of the dewatering system, not general mechanical completion. The commercial problem is that the dewatering line may already be operational, but the payer is still holding the final balance until the performance results are accepted. Your email should ask whether the sludge dewatering test is the only remaining blocker, whether the latest performance run has already been completed, what dryness, throughput, or polymer-performance issue remains unresolved, and whether payment will be released once the report is approved. The result you want is a release path tied to one exact dewatering-performance deliverable instead of vague statements about incomplete process optimisation.
