On CAPS, 99% of the 1,018 members who have rated SABESP believe the stock will outperform the S&P 500 going forward. These top-ranked bulls include globalsailor and aitraders.

Late last year, globalsailor summed up SABSEP in purely bullish terms:

It has little debt, reasonable earnings, it gets its income in Brazilian reals and it is trading ridiculously below its book value. Brazilian sanitation and water delivery will definitely have to improve so the growth prospects are quite good. If I had the money I'd buy the whole company.

In an earlier pitch, aitraders follows that line of thinking:

As the city of Sao Paolo, one of the world's biggest, continues to increase their middle class, they should have ability to grow network and rates as [Brazil] becomes one of [South America's] strongest economies.

Down side is effort required to keep up with financials (reported in REALS), govt. involvement, irregular dividend payments, and potential currency fluctuation, however, the basic service of providing water and sewage with govt. authorization is about as big a moat as you can get.
