Sewer cleaning services

Summary

The tender concerns cleaning and inspection services for gullies and channel drains in public areas across the municipality’s entire work area. The work is carried out in two rounds: a large round and a small round. Sludge, sand and waste are removed to ensure proper drainage, and any defects or blockages found during inspection must be reported to the contracting authority. The contract is not divided into lots. The large round covers about 29,500 gullies each year and no channel drains; the small round covers about 9,000 gullies and 2,000 metres of channel drains each year.
