BA-26-004-GK Consultancy services for the preliminary project for joint treatment facilities.

Gjøvik municipality has, together with Vestre Toten municipality, prepared a feasibility study for future sewage systems connected to Breiskallen RA at Raufoss and Rambekk RA in Gjøvik. The reason for the study is that the Government Manager, pursuring the EU's sewage directive and pollution regulations, has warned of stricter requirements for emissions of municipal sewage water. As a result of this, major investments must be made in new or upgrades/expanding the existing treatment facility in order for the municipalities ́ sewage services to fulfil these treatment requirements. The government administrator has notified a deadline to fulfil the new requirements by 2031. The conclusions from the feasibility study are that there are considerable costs to save on collaborating on a regional treatment facility. Based on this, gjøvik and Vestre Toten municipalities have decided to cooperate on upgrading and expansion of a regional treatment facility. The two municipalities will now continue to work on establishing a joint treatment facility, as well as a transfer facility between the municipalities through the preparation of a preliminary project in 2026. The treatment facility shall be established in connection with the existing treatment facility at Rambekk in Gjøvik municipality. The plant shall fulfil the current purification requirements for the removal of phosphor and organic matter and expected requirements for purification of nitrogen. The treatment plant shall also be dimensioned so that any sharpened purification requirements of the current parameters can be safeguarded. In addition space shall be set aside for possible quarternary purification in the future. This procurement concerns consultancy services for a preliminary project that is included in a larger project with a combined expected value that exceeds the thresholds in the supply regulations § 5-2. The procurement will therefore be carried out in accordance with parts I and part II of the regulations.
