100 Years of Clean, Safe Water
This brief history of Evanston's water system outlines how the original 1874 pumping station was transformed over the years into the City's current water treatment facility.
1912 Report of Special Committee of City Council
City residents and leaders who championed the ultimate construction of Evanston's 1914 Filtration Plant began their campaign by forming a "Water Committee of the Council". The committee was charged to investigate options to end the typhoid and cholera epidemics that had plagued Evanston for so many years. The committee, along with its consulting engineers, prepared a detailed report on options for reducing waterborne disease, ultimately recommending construction of a water filtration plant.
1914 News Article on Startup of Filtration Plant
This July 1914 news article is an example of community outreach aimed at educating residents on the safety of the water due to the filtration plant. It had been common to boil water before consumption due to the prevalence of waterborne disease, and it took some time for people to get used to the fact that their water was now safe to drink at all times (in addition to looking and tasting much better).
1915 Journal AWWA Article on Filtration Plant
This is a journal article on the design and construction of Evanston's 1914 Filtration Plant is an interesting glimpse into the water works design standards and construction methods that were considered state-of-the-art 100 years ago.
The following table provides a history of the water rate charged to Evanston residents since 1921. Water bills were sent out on a quarterly basis until September of 1990, when the billing cycle was changed to bimonthly. The water rate is used to finance all aspects of the operation & maintenance, capital, and debt associated with the Evanston Water Utility.

Sewer Rates
The sewer service charge was first initiated in January of 1978. It was developed to provide funding for the operations of the Sewer Fund in addition to excess revenues from the Water Fund. With the inception of the Long Range Sewer Improvement Program and the high costs associated with that massive project, a formula was developed for the establishment of the sewer service charge in conjunction with the budget process each year. The Service Charge is now directly based on the expenses, transfers, use of fund balance and investment income as reflected in the budget.
