A prestressed tank will not crack until the tensile stress overcomes the precompression plus the cracking tensile strength.
Obviously a tank with no cracks is desirable.
RE: Concrete Tanks
One difference also is that AWWA has standards on various prestressed tanks, but not on cast-in-place tanks. Typically, on modern tanks in the US, I've seen non-prestressed cast-in-place tanks used mainly for raw water or water treatment; that is, places where leakage doesn't really matter that much. Most of the CIP tanks I've seen used for potable water were also very old.
Another difference is that the prestressed-tank people generally want to do bigger tanks, and not, say, a 50,000 gallon tank. The prestressed tanks are generally aimed at circular tanks, also.
