[Halden kommune](https://tendernation.io/buyers/halden-kommune) Estimated value Not stated Published 21 Apr 2026 Deadline Closed 26 May 2026 ## Who can bid - Open procedure Anyone can submit a full tender; there is no shortlisting stage. ## About this tender The competition is for the delivery of complete engineering design services for nitrogen purification at sewage treatment plants and complete detailed regulation. The procurement ́s value is estimated to: Above the EEA threshold value. The volume is an estimate and is not binding for the contracting authority. See the procurement documents for further information. The contracting authority reserves the right to cancel the competition, i.a. in connection with budgetary conditions. This procurement is considered to have an immaterial impact on climate and the environment, cf. the Regulations § 7-9, fifth paragraph. The justification for this is that the procurement is for consultancy services/consultancy services where the contracting authority has been cut off from affecting climate and environmental impact, as the requirements and criteria that are aimed at these elements will not have sufficient connection to the delivery, cf. DFØ's environmental supervisor. Apprentices: The contracting authority has assessed the procurement against the apprenticeship regulations, cf. the Procurement Act § 7 and concluded that there are no requirements for apprentices in this procurement, as the main elements of the contract do not include work where it is relevant to use labour with vocational certificates of apprenticeship or craft, subsidised that it is considered disproportionately, because there is a need for specialised competence that an apprentice cannot be expected to possess. Cf. the apprentice regulations §6 (3) and (4).
