The David City Water Treatment Plant Upgrades project demonstrates how engineering innovation and community-focused design transformed a 40-year-old facility into a state-of-the-art system prepared for future growth. Confronted with aging infrastructure, labor-intensive operations, and water-quality challenges, David City partnered with JEO Consulting Group to implement Nebraska’s first municipal Closed Circuit Reverse Osmosis (CCRO) system.

Project improvements included rehabilitation of the aerators and gravity filters; construction of a new intermediate clearwell and pump building; cleaning and upgrades to the final clearwell; improvements to the backwash tank; enhancements to the chemical feed systems; installation of a new security system; and comprehensive building upgrades, including roof replacement, paint, flooring, HVAC, lighting, and plumbing.

The advanced CCRO process achieves an 85–92% water recovery rate, compared to approximately 75% for traditional reverse osmosis systems. This increased efficiency reduces waste and alleviates strain on the wastewater treatment plant, which was operating near capacity. In addition, a degassifier minimizes the need for chemicals used in pH adjustment and is projected to pay for itself in less than one year.

Automated controls and remote monitoring allow operators to manage the system more efficiently, reducing labor demands and minimizing the risk of downtime.

Despite limited site space, the project team successfully integrated new and existing systems within the original facility footprint while maintaining full plant operations throughout construction. Careful phasing, detailed sequencing, and daily coordination among the contractor, engineering team, and City staff ensured uninterrupted water service.

Funded through the Nebraska State Revolving Fund (SRF) Program — which included more than $6.3 million in loan forgiveness — the project extends the plant’s service life by more than 20 years, enhances water quality, and positions the City to support future growth. Public outreach efforts and facility tours further highlighted the project’s impact, demonstrating how engineering innovation protects public health and promotes long-term sustainability.
