Ten years in planning, the new water plant went online percent on March 7,designed to better serve Iowa City’s growing population. Daytime winter temperatures in Iowa City are routinely in the 30s, but may plummet after dark, so low temperature tolerance was another important duraplage in product selection.

For further duraplatf, phone The new plant’s compact design and significant use of concrete construction, including two two-million-gallon storage reservoirs, distinguish the Iowa City water treatment facility.

As home to the University of Iowa, Iowa City lays claim to many “big city” attributes: A computer glitch at a filtration plant may have allowed minerals to seep into the water turning the water brown in Lake Station, Ind.

Before the treatment plant was closed in, some initial painting occurred during the coldest months of the year in Iowa City. By enlisting the services of engineering firm Howard R.

It also is suitable for use in USDA-inspected facilities.

As weather and temperature conditions improved, Dura-Plate continued to be used on interior PVC piping, ductwork, conduit and other galvanized and concrete surfaces throughout the water treatment facility.

Dura-Plate is an epoxy phenalkamine formulated specifically for service in industrial and marine environments. More than durwplate, yards of cast-in-place concrete were utilized in the plant’s construction. With its greater water treatment capacity, the new facility is another tool for attracting to the Iowa City area companies requiring large amounts of water.

Brown Water in Indiana Town. Iowa City’s population fluctuates regularly due to the arrival and departure of its college students — some 30, in number — during the year.

The masonry contractors prepared interior concrete surfaces by “rubbing” duraplzte “sacking” after the placement and the removal of the formwork. This process provides a dense, uniform surface that is rougher than that provided by steel troweling and ready to paint immediately after drying and curing.


Specialty coating required in containment areas In areas where even greater chemical protection was required, Sherwin-Williams Shelcote II was specified, according to Duben. According to Mohling, the epoxy’s low temperature properties allowed his crew to work unhindered despite the temperature, and to obtain the required film build and spread rate.

The previous treatment plant, which the new facility has replaced, was nearly years old. The plant uses a combination of surface and ground water sources for better overall water quality.

Dura-Plate PW – Protective & Marine

Green Company, the city durplate to create a structure that would meet its immediate and future requirements for the next 50 to years. For long-term corrosion protection, and the ability to maintain the plant’s “clean” appearance, high performance epoxy coatings from Sherwin-Williams were selected for these surfaces.

All coating systems maintained a DFT between 6 – 10 mils. Acrolon HS is a two-component, low VOC, acrylic polyurethane coating designed for high performance protection when maximum exterior gloss and color retention is needed.

This aquifer covers nearly all of the state of Iowa and is used by many communities as a major water supply source.

The selection of protective coating systems was a critical consideration of Howard R. Water is also supplied by four shallow alluvial aquifer wells and one deep well that penetrates the bedrock of the Jordan aquifer.


The majority of water comes from four horizontal collector wells with direct intake from the Iowa River. We needed something that was low-maintenance and easy to wash down,” says Bradbury. Two coats of this high performance epoxy were then applied to a 5 to 6 mil, DFT per coat. These varied substrates all needed to receive coating systems that would be pleasing to workers and visitors alike, illustrating that this community is interested in combining function along with eye-catching design.

Rick Snyder made the call to stop distributing water. Because construction was scheduled to take place during winter months, some of the coatings applied had to be tolerant of low temperatures. In areas where even greater chemical protection was required, Sherwin-Williams Shelcote II was specified, according to Duben.

All projects must have been in the design or construction phase over the last 18 months.

As a result, water consumption and treatment fluctuate. After the surface was prepared, two coats of the multi-purpose epoxy were applied at 4 – 6 mils dry film thickness DFT per coat on interior concrete walls and ceilings as well as steel columns, beams, and stair stringers.


Improving taste and odor was a goal to improve the aesthetic duaplate of our water. In addition, the protective coating systems for this project were also intended to enhance operation and maintenance efficiency.

This was particularly helpful durqplate this project, because city officials emphasized the importance of cleanliness and maintenance efficiency as they likened their plant requirements to the strict standards typical of food processing environments.

Duben specified Shelcote II — a high-solids, amine cured epoxy coating designed for resistance to a broad range of aqueous and petroleum-based chemicals including MTBE. This is in addition, of course, to fulfilling the facility’s primary aim: Dura-Plate was submitted and approved, according to Dave Kelchen, Sherwin-Williams Industrial and Marine Coatings specialist, because the product is specifically engineered and formulated to control corrosion and provide maximum durability and resistance to frequent water washdowns, chemical solvents, and abrasives.

By taking a combination of water from the river and the aquifers, we are protected against potential contamination from any one source. It is also designed to meet ever-increasing state and federal drinking water quality standards, and to improve the taste and odor of the water supply for the area’s Hawkeye State citizens. If you can keep the facility cleaner, it’s much easier to maintain the quality of the water.

Among the regulations that created the need for new plant construction were lower maximum contamination levels MCLs on inorganic chemicals, organic 2355, and radionuclides, according to Shaun Bradbury, special projects manager of Iowa City.

Green Company to ensure long-term corrosion protection and chemical resistance. Rubbing a concrete surface with additional concrete or grout is done to prevent the formation of holes and voids. The new plant was constructed dhraplate concrete and houses several steel and fiberglass processing tanks and storage vessels. A man-made lake located on the plant site will provide a supplementary source of water.
