Which water company supplies L30?

Is the water in L30 safe to drink?
Yes. Slightly Hard water at 67 ppm is safe to drink. Water hardness affects taste and can cause limescale, but it is not a health risk. In fact, hard water contains beneficial minerals like calcium and magnesium.
How can I reduce water hardness in L30?

What does 67 ppm water hardness mean?
67 ppm means there are 67 parts per million of calcium carbonate dissolved in the water. This is equivalent to 4.7 Clark degrees, 3.8 German degrees, or 6.7 French degrees. Water above 180 ppm is generally considered hard.
What size water softener do I need in L30?
For a typical 4-person home at 67 ppm, a 24,000 grain softener is a sensible size. It would regenerate roughly every 40 days. Larger households or higher daily use need a bigger unit. These figures are conservative estimates.
How much does it cost to run a water softener in L30?
At 67 ppm, expect to use about 14 kg of salt a year, costing roughly £4–£7/year. Water is soft to moderate, so limescale and soap costs are low and a softener rarely pays back.
