I live and work here in Woolwich Township. Many of the developments are public water and sewer. Many of the older homes are well and septic. Depending of what type of water supply you are looking for is where you should start looking in to if you are looking to buy. I know the area very well and would be happy to help you in any way I can. If there is a specific area in Woolwich, that you are thinking about please let me know and I will tell you if public or privet water is there. Call me anytime.
