A. General Requirements:
1. An adequate supply of potable water shall be provided to every platted lot in accordance with Illinois Environmental Protection Agency regulations. If a public water main is not accessible, the developer shall take necessary action to extend water mains for the purpose of providing a water supply system capable of providing for domestic water use and fire protection.

All water mains shall be at least eight inches (8") in diameter. In certain instances, the Public Works Director or designee may require water mains to exceed eight inches (8") in diameter. In these cases, the Village will pay no cost for water mains up to twelve inches (12") in size. Should a water main larger than twelve inches (12") be required, the difference in material cost only will be paid for by the Village. The difference in material costs between an eight inch (8") main and the size required by the Public Works Director or designee will be paid for by the Village.
3. Water main extensions shall be approved by the Public Works Director or designee. (Ord. 2015-18, 4-28-2015; amd. Ord. 2018-07, 4-24-2018)
