Time kommune receives its water from IVAR, the inter-municipal supplier for the Stavanger region, and describes it as soft at 3 °dH, or 53.5 mg/L CaCO₃. The page was last edited in January 2023 and gives no measurement date, so the figure may have changed. Scale is modest but can show on kettles and taps over time.
Norwegian waterworks report hardness in °dH or mg/L Ca; most supplies are very soft.

- Dishwasher: salt setting at minimum or off.
- No softener needed; a jug filter only changes taste.
