Building wells in Gaza only results in more water from the aquifer that is contaminated by seawater. Gaza requires water to be imported (which Israel limits to an amount a small fraction of the needs of Gaza), or desalination, which is impossible in large enough quantities under the blockade. Further, Israel routinely attacks or cuts off the electricity generation capacity for Gaza, which in turn makes desalination impossible.
And also, you keep shrugging off the actions of the Israeli government in the West Bank as if that does not factor into how people in Gaza respond. Sure, the Israeli government routinely brutalizes residents of the West Bank, but why should people in Gaza notice that? Why can't they just pretend that is some wholly separate issue that has nothing to do with Gaza, and not a deliberate attempt by the Israeli government to make the occupied territories non-viable as a future state?
Why do you think Gaza requires water to be imported?!
Incredible how Hamas have electricity and clean water, isn’t it? They could have easily invested in infrastructure to obtain clean water, they’ve had 20 years and obscene amounts of aid money that has been provided for precisely this purpose. The EU themselves have helped in specific projects, building water pipes for this reason but Hamas, themselves, have shown videos of them digging these exact same pipes up to use for weapons. Do you expect Israel to subsidise their water while their government simply steal it and quite literally weaponise it?
I’m not shrugging the West Bank off, a more centrist government is what’s needed. Israelis have sympathy for those people, too. Focussing solely on this is reductive and plays no part in Hamas’ stated aims.
It’s also important to consider that these are people that have been displaced from their original homes in Iraq, Libya, Iran, Jordan where hundreds of thousands of Jews have been effectively ethnically cleansed, so it’s a vicious circle that needs to be part of any two state solution.
