Romanian survey: asprete count drops on Vâlsan, Brădetu WWTP blamed (Sept 2026)

Published: Oct 7, 2026

A September 2026 survey on Romania's Vâlsan River counted 150 asprete fish, down from 181 in 2025, with the Green Belt Foundation blaming chronic non-compliance at the downstream Brădetu wastewater treatment plant for a fall from 68 to 36 fish downstream of the works. Nearly EUR 500,000 from Romania's 2026 state budget has been allocated to restore the Brădetu plant to required operating standards, and a five-year LIFE ASPRETE proposal was submitted to the European Commission on 22 September. For plant managers and buyers, the event is a case study in how a compliance failure at a single small municipal works, combined with unmaintained ecological flow from the Vâlsan dam and Dobroneagu intake, can collapse a downstream population in one year and turn a process upgrade into an emergency capital line.
