We had a leak from our water storage tank and in order to replace the platform that the tank was on, I disconnected all the pipes from the tank. There are three 22mm pipes that connect at low levels, and one 15mm pipe that feeds the tank near the top.
Now that I've removed the pipes, I am worried that the compression joints on these will not seal properly when I connect them again. What can I do to help improve the chances of making them watertight?

It's important to make sure that the olive fits exactly square on to the fitting and is completely clean. Any trace of dirt and you're likely to prevent a proper seal.
I'd not advise using PTFE thread-sealing tape over the olive itself, rather over the thread to which the nut is connecting.
