In September 2002, the Northeastern Illinois Planning Commission (NIPC) adopted its Strategic Plan for
Water Resource Management. The plan addressed a number of issues involving water quality, flooding,
and water supply in the region. Their examination of water usage in northeastern Illinois indicated that
despite the proximity of one of the largest supplies of freshwater in the world, Lake Michigan, water
supply is still a concern for the area. Continued population growth is accompanied by an increase in the
demand for water in the region. NIPC conducted a 2020 water demand and availability analysis by
township based on projections for population, economic activity, and consumptive use by source. The
overall conclusion of the analysis was that there will be a significant increase in water demand between
