Treated wastewater is almost waste itself, because at least in the United States we're reluctant to use it for agriculture for the obvious reasons. And trees aren't particularly large consumers of water, because the irrigation methods are non-lossy. Not spraying sprinklers up in the air so half is lost to evap. Or flooding little furrows in between the rows of a crop. It's not that big of a challenge, at least water wise. Infrastructure, if anything, is the problem... cities would have to go digging up a fuckton of sidewalk, and spend extra on maintenance every time there's a leak. Worse still, is having two separate water systems (can't connect to the potable water mains).

Wastewater depends ... residential greywater can be used onsite if the residents are careful about the type of detergents they use. There are methods to treat blackwater onsite (more than just a septic tank and a leech field). For trees, I think the biggest factor is if you use woodchips in a basin. Even a six-foot diameter with 1 ft depth, filled with arborist chips makes a huge difference in water retention and nutrition for the trees. These are rain water harvesting structures that do not require a drip system.
