Our Solution

• Nine Horizontal Flocculators & nine Rectangular Collectors

• Lightweight, corrosion-resistant non-metallic materials

• Reduced maintenance and long service life

Overview
Serving more than 47,000 residents, Newark’s water system draws from the Licking River and treats it through a network of 188 miles of water lines. To optimize reliability and reduce maintenance, the city partnered with E & I Corporation to install nine Horizontal Flocculators and nine Rectangular Collectors.
Each unit incorporates advanced, lightweight, corrosion-resistant materials engineered for longevity. The design minimizes maintenance downtime and supports efficient floc formation and solids collection.

With over 25 years of proven operation, Newark’s installation demonstrates how innovation in material selection — from reinforced fiberglass to precision-molded plastics — extends equipment life and enhances water quality across municipal systems.

Key Highlights

• Installed in 1978 and still operating with minimal maintenance

• No underwater parts requiring replacement

• Fully automatic, mechanized cleaning

• Protects downstream pumps & process equipment

Overview
Since 1978, the Glenbard Wastewater Authority has relied on E & I Corporation’s Catenary Bar Screens to safeguard its primary treatment system. Operating continuously through countless flow events, these heavy-duty, front-cleaned screens provide dependable performance with minimal attention.

According to Senior Operator Erick Lanphier, “These screens have had absolutely no problems — they’re dependable workhorses.” By intercepting debris before it reaches raw pumps, the screens extend the mechanical life of downstream equipment and maintain biological process stability.

Working in tandem with nearby Lombard’s E & I installations, the Glenbard facility handles peak combined sewer overflows of 50 MGD. Over 25 years of uninterrupted service prove why the Catenary Bar Screen — often copied, never duplicated — remains the benchmark for rugged reliability in municipal screening.

Key Highlights

• Installed in 1978; decades of operation with no major repairs

• Screens an average of 7.5 million gallons per day

• Serves 13,000 connections across a 36,000-person community

• Durable carbon-steel frame & fiberglass covers

Overview
Westerville’s E & I Traveling Water Screen has achieved what most equipment only promises — 33 years of uninterrupted, maintenance-free operation. Installed in 1978, the system continues to screen an average 7.5 MGD from the Alum Creek River without any major component replacement.

Built from rugged carbon steel and fiberglass-reinforced components, the screen’s dual-chain, basket-mesh system efficiently removes debris while minimizing mechanical wear. Its longevity is a testament to E & I Corporation’s precision engineering and fabrication standards, trusted by leading consultants such as Burgess & Niple, Black & Veatch, and the U.S. Army Corps of Engineers.

Decades later, Westerville’s screen continues to exemplify durability, reliability, and the high performance synonymous with E & I Corporation water-screening systems.
