A water tank affecting the balance on a boat that size? It doesn't sound like a valid reason, passengers and gear affect the loading of a boat, seems to me a water tank should have little effect on a well engineered craft. I have a slightly larger rib than yours (9 meter) and have had as many as eighteen people on board under way and have not noticed that affecting "balance".
This boat also has two 125 gallon fuel tanks port and starboard, they have been full and empty and that hasn't noticeably affected it either. How much room do you have in the bilge? Maybe it would have been difficult for them to install on your boat?
They do have the collapsible (soft) water tanks (bags) on the market, if someone wants fresh water for drinking or showering these work well enough for most smaller boats.
