How to I deal with sewage better? I am using water treatment plants instead of pipes and it is still bad.

Do I need to spread them out more?

You always need pipes. Water treatment plants just allow you to produce less pollution and can be placed on land as opposed to on a shore.

And you could drink it if you wanted to, but then I start out by getting my fresh water straight out of a out of town mountain spring so.....

If you want sewage to "just go away" and use just use sewage treatment plants on the workshop as non functioning decorative assets, then I recommend "Poop Evaporator" by XombieDark.

There are inland water treatment plants in Sunset Harbor DLC, that pump pollution in the ground but don't pollute the ground nor water.

As others have suggested, if you don't want to pollute your rivers, lakes, etc. then you need either mods or DLCs.
- The Green Cities DLC adds Eco Water Treatment Plants, which have a discharge pure enough that it's usually quite difficult to see the pollution plume unless you have a lot of them in a small area (though it's still not advisable to place pumping stations downstream of Eco Water Treatment Plants unless you do something else to purify the water), and Floating Garbage Collectors, which can make the water downstream of them completely pollution-free if placed in sufficient quantities regardless of how polluted the water is upstream.
- Sunset Harbor adds four inland water treatment plants, which have already been mentioned, and adds the Algae-based Water Filtering Policy, which reduces the pollution in the discharge from Water Treatment Plants and Eco Water Treatment Plants.

If I recall correctly, combining Sunset Harbor's Algae-based Water Filtering policy with Green Cities' Eco Water Treatment Plant results in the discharge of the Eco Water Treatment Plant being pure enough that you won't have problems even if you put water pumping stations immediately downstream of a large number of Eco Water Treatment Plants.
