What happened

Seafield WWTW processes a reported 265 million litres of wastewater per day. It is operated by Veolia under a PFI arrangement. The £10 million Seafield Sludge Investment Project is intended to add storage capacity and move odorous sludge from open areas into covered, extracted facilities. Construction is scheduled to start in summer 2026 and finish by end-2027. The City of Edinburgh Council investigates strong and persistent sewerage odours. SEPA addresses odour associated with waste treatment.

What we haven’t found

BioVeracity has not located the following in the public sources reviewed for this place. Absence here is not proof that nothing happened — only that the record is, so far, silent.

  • No agreed quantitative post-project odour criteria supplied

    Why it matters: Completion in 2027 may not resolve debate over effectiveness without pre-agreed measures.

    What would resolve it: Odour outcome definitions agreed by Scottish Water, Veolia, Council, SEPA and stakeholders
