Colorado's treatment plants must accommodate the state's growing population, which is projected to increase 65% over the next 25 years.
Denver Water's Marston treatment plant has a 250 mgd capacity. Due to population growth, Colorado will need an additional 205 billion gallons of new water by 2030.

The Windy City gets ready to serve its burgeoning population.

With the population of the six-county Chicago metropolitan area expected to increase by 1 million over the next 20 years, devising a comprehensive water management plan presents a tough challenge.

That's why the Illinois Water Supply Initiative is taking a regional approach to water demand and supply.

Launched in June, the state-funded Water Supply Initiative is expanding on water-planning programs that have been launched by western Kane and northern Lake counties, where drought and dry wells already are straining water supplies. Kane County, the Chicago area's recognized leader in water planning, is conducting a four-year study with the Illinois State Geologic and Water surveys to refine its strategy for maintaining water resources. The county, which experienced a 15% population growth in four years, invested $2 million in water conservation efforts, reducing water use in some areas from 100 gallons a day to 65 gallons a day.

Research and planning within individual counties like Kane County will help the Illinois Water Supply Initiative make specific plans for each area.

The initiative has a five-year funding plan and will receive $1.05 million in fiscal year 2006. The money will be administered by the Department of Natural Resources, which has a proposed fiscal year 2007 budget of $203.6 million, $16.5 million more than in 2006. — Ashley Trent
