The City of Highland Park takes pride in providing safe drinking water to our customers. The water that reaches your home or business meets all State and Federal drinking water standards and is safe to drink. However, contamination can occur within your own piping system. The greatest potential hazard is known as an unprotected “cross connection”, which can cause backflow to occur.
The State of Illinois and the US Environmental Protection Agency have established rules that require the City of Highland Park to identify potential cross connection hazards and take appropriate actions to protect against the possibility of backflow occurring. The City has established a protection program of the public water supply. The Cross Connection Control Program is designed to ensure the safety of the water supply by providing protection from the entry of unwated and possible dangerous material into the drinking water supply.
