The idiots in WDC have a habit of passing catch all regulations. They might be needed for some but they pass them for everyone, even when not needed. I can see that some big cities have water shortages and that some changes needed to be made, like low flow toilets, showers, and kitchen faucets. So, the geniuses in WDC forced them on everyone, needed or not. We have a well and septic. All the water that goes down our drains ends up back in the ground., no net loss to the aquifer. I really hate standing in front of the sink waiting for it to fill because some genius decided that I shouldn't get more than 2 gal/min out of a faucet. It doesn't save any water. It only costs me time waiting for it.
