Andover Township’s water infrastructure history spans over 160 years, beginning with its incorporation in 1864 from portions of Newton Township. The township’s expansive 21 square miles of rural terrain, home to approximately 6,000 residents, has historically depended on a decentralized approach to water supply, combining private wells with regional coordination efforts.

The township’s water development paralleled broader Sussex County initiatives under the North Jersey District Water Supply Commission, established in 1916 to coordinate municipal water supplies across Sussex and neighboring counties. This regional framework helped address the unique challenges of providing water service across the township’s diverse topography, which includes glacial lakes, limestone outcroppings, and varied geological formations.

Private wells have remained the predominant water source for many township residents, taking advantage of the area’s favorable hydrogeology. The New Jersey Department of Environmental Protection’s Division of Water Supply & Geoscience oversees both municipal systems and private well installations, ensuring compliance with state water quality standards and safety regulations.

Modern water management reflects the township’s commitment to environmental stewardship and sustainable development. Sussex County’s comprehensive wastewater management planning coordinates public water supply oversight with private well management, maintaining the mixed infrastructure approach that has served Andover Township’s rural character while supporting its growing residential and business communities.
