I can't stand water saws because it hard to contain muddy mess, usually sprays water/mudd mixture over anything in its path and it stains anything and if your cutting something with color in it, thats even worse, it also water logs your hands and takes 3 times longer to do the same job. Dry cutting is the only way to go, so what if you have to wear a mask, cuts done in long lines with dry cut looks 100 times more accurate and clean looking, i work in residential areas in the city all the time in Canada its not against the law but you will definitely get grief from neighbors, I just tell them to be patient cutting only lasts a couple days at the most.
