The MAX Orange Line will open on schedule on Saturday, Sept. 12, 2015, and while construction is 95 percent complete, the federal funding process continues through 2019.

The most common household form of water softeners are ion-exchanging resin devices. There are three main types of water softeners, categorized based on what salt they use: sodium, potassium, or hydrogen. These water softeners have a bed of resin that water is passed through. The resin is negatively-charged, and so binds to the positively charged metal ions in the hard water.
A filter will not remove dissolved solids (which are responsible for hard water). A descaler, (Salt Free Softener) does not remove dissolved solids, it prevent the solids from being deposited inside pipes, on fixtures, etc.. A water softener is a true water treatment system. The dissolved calcium and magnesium carbonate (which are responsible for the hard water) in the water are replaced with either sodium chloride (salt) or potassium chloride.
