Sewage treatment plants

Wish I had the numbers at my fingertips, but Zihuatanejo is very progressive, for Mexico, in terms of sewage treatment plants. The number 11 seems to come to mind as to the number of them.

There aren't many other treatment plants along the coast.

We have one in La Ropa, two-in-one in La Noria, and one in Ixtapa. Most towns up and down our coast and in the sierra of Guerrero don't have sewage treatment plants.
