It's just a lot of salt. Seawater (on average) is 3.5% salt. So for 1kg of water (aka 1 liter) you get 35 grams of salt. For 5 thousand liters, thats 175kg of salt. While we do use salt for industrial purposes, that salt is usually treated and chemically processed for sanitary reasons. Given the average person uses 310 liters of water a day (drinking, cooking, cleaning, ect...) 5,000 liters gets you slightly more water than 16 people are going to consume in a day. And 175kg of salt is way more than 16 people are going to use in a day. Now figure this system runs all year round, and we have 63,000kg of salt. Just so 16 people could drink desalinated sea water all year.

There are a number of theories put forth in recent years how best to desalinate sea water for drinking water and disposing of that salt, most of them involve dumping it in the desert, burying it in old mines, or possibly deep sea operations where salt concentrations are already too high for most life to exist, so adding salt to those regions won't have a ecological impact and it's possible for currents to spread that excess salt over a wider area.

Every one of these options has downsides, but we do need water to live and oceans are a vast source of water we aren't really tapping so you can see the desire to utilize them when majority of the global population lives within a hundred km or so of a coast line.
