VAV [the municipal Agency for Water and Wastewater Services] needs to enter into a new framework agreement for the purchase of burned lime, CaO, for Oset water treatment plant and hydrated lime, Ca(OH)2 for Skullerud water treatment plant.
The requirement for the purchase of burned lime to Oset water treatment plant is estimated to 1700 tonnes per annum. The requirement for the purchase of hydrated lime to Skullerud water treatment plant is approx. 300 tonnes per annum. The consumption is equally divided during the year. However, the consumption may vary in relation to the production of water. The stated scope is based on the current annual consumption. The concrete call-offs are dependent on VAV's changing need during the agreement period.
Water treatment chemicals must be approved by the Norwegian Food Safety Authority in accordance with § 14 in the Drinking water regulations.
