About Us

Quality on Tap

Central Iowa Water Association is a private, nonprofit corporation established in 1977 to provide water to rural residents, small communities, developments, recreational facilities, and rural-based businesses throughout central and northeast Iowa. In 2000, we added wastewater collection and treatment services in designated locations.

Our Commitment

Our goal is to provide our member-customers with a safe, softened, high quality, and dependable supply of water. We are committed to ensuring the quality and dependability of the water we provide our customers.


Each year, CIWA provides more than 1 billion gallons of high quality softened water to our member-customers. CIWA's service territory includes all or portions of 17 counties in central and northeast Iowa. CIWA serves 70 small communities through three different types of connections:  community franchise, bulk connection, and emergency or supplemental connections. Grundy Center, CIWA's largest community customer, is served with a bulk water connection.


CIWA facilitates wastewater services for unsewered small rural communities and densely populated rural areas where individual septic systems pose environmental concerns. CIWA's wastewater services assist those in need of alternative wastewater disposal options.

CIWA Membership and Directors

Central Iowa Water Association is member-owned with more than 12,500 individual, small business, and community connections. A nine-member Board of Directors, representing geographical regions throughout the system, governs the private, nonprofit, member-owned Association.

Central Iowa Water Association was founded in 1977 as the Jasper County Water Association. The founders of the Association believed that establishing a means of providing a safe, dependable source of potable water to rural residents would be essential for the continued vitality of Iowa's rural population. Jasper County Water Association founders began their efforts to sign-up rural water member-customers in 1978.

Recruitment efforts developed a strong base of member-customers for the Jasper County Water Association. The original system, with headquarters in Newton, was defined by boundaries of Jasper County, extending into a small portion of Polk, Marion, and Marshall Counties. The original 950 miles of pipe, with some 2,000 member-customers, took nearly two years to install and bring into full service. This original area now represents only 25 percent of the current distribution system.

CIWA purchases its treated, softened supply of water from Newton, Marshalltown,and Pella waterworks. Water is pumped by large booster stations to the 19 water towers strategically located throughout the system, two of which are 2 million gallon hydropillars. Gravitational flow, as well as additional pumping stations enable the system to provide water service to a growing member-customer base.


Rural water at your tap provides you with a clean, safe dependable supply of water every day. Just 4 cents will buy you approximately five gallons of water from Central Iowa Water Association!  

Many private well systems cost significantly more than rural water service when customers evaluate their total operational expenses:

  • depreciation
  • interest costs
  • maintenance
  • electricity
  • water softener
  • salt
  • in-home treatment
  • water tests

The following information will assist you in understanding of the actual expense in operating your well system.

A new well in Iowa typically costs approximately $5,500 to $9,500. This may or may not include your water well pump ($750 - $950), pressure tank ($150 - $550) and water softener ($550 - $950). Once installed, the system is depreciating, or reaching the end of its useful life, at the rate of approximately $52.00 per month. Add the cost of operation, maintenance, electricity, salt for the softener, in-home conditioning, water testing, and interest on the total investment, and the total cost can easily reach more than $100.00 per month.

Typical Well System (Example Only)
Installed Cost Useful Life Monthly Depreciation
Well $7,500 40 years $15.00
Well Pump $850 5 years $14.00
Pressure Tank $350 10 years $  3.00
Water Softener $750 3 years $20.00
$9,450 $52.00 per month




$  8.00 per month

Salt $10.00 per month
Interest* on total installed cost ($9,450 at 5 percent) - $39.00 per month

(*Note: Regardless if you borrowed the money from a lending institution and are paying interest or paid cash and no longer are collecting interest on the money paid, you still have an interest cost.)

$109.00 per month
