Modern plastic tanks cope very well with the intake. That's why Modern septic tanks and sewage systems are made of Plastic. 

You need to make sure that thy are vented through the lavy is best as they can implode when being emptied. 

Emptying frequency normally is in ratio to the crews diet,liquid intake and the availability of shore based facilities.

I think most modern tanks are now MDPE, the average lifespan of which is around 50 years.

Probably best to replace before that point, as a black tank explosion is not something I'd want to be dealing with!
