Delmar Unveils New State-of-the-Art Wastewater Treatment Plant
In December 2011, the Town of Delmar proudly opened its brand-new, state-of-the-art wastewater treatment facility. Designed to serve the growing needs of the community, the upgraded plant promises improved efficiency, higher environmental standards, and greater capacity for future development.
With this new facility, Delmar is making a bold investment in sustainability, clean water, and regional growth.
A Big Upgrade for a Small Town
Located on the border of Delaware and Maryland, Delmar may be small in size, but it now boasts a modern wastewater system that rivals those found in much larger cities. The project represents a $9 million infrastructure improvement, financed in part through low-interest loans and grant support from both the U.S. Department of Agriculture (USDA) and the Maryland Department of the Environment.
The old facility, which dated back to the 1980s, struggled to keep up with both increased population and stricter environmental regulations. In contrast, the new plant uses advanced treatment technologies to ensure cleaner effluent and better protection for local waterways.
“This project helps safeguard our water and prepares Delmar for the future,” said a town official at the ribbon-cutting ceremony.
New Technology, Cleaner Results
At the core of the facility is a biological nutrient removal (BNR) system. This method removes nitrogen and phosphorus from wastewater—two pollutants that contribute to harmful algal blooms and poor water quality in rivers and bays.
In addition, the plant features:
- Ultraviolet (UV) disinfection, which replaces older chlorine-based systems
- Modern monitoring equipment for real-time data tracking
- Energy-efficient pumps and motors, reducing electricity use
By installing this cutting-edge system, Delmar joins other municipalities working to restore the Chesapeake Bay watershed—a vital resource for both states.
Meeting Environmental Goals with Delmar’s Wastewater Treatment Plant
The Chesapeake Bay has long suffered from nutrient pollution. According to the Environmental Protection Agency (EPA), excess nitrogen and phosphorus cause dead zones, fish kills, and a decline in aquatic vegetation. Reducing these nutrients at the source is a critical step in restoring the Bay’s health.

Delmar’s new treatment plant now discharges cleaner water into the Little Creek, which flows into the Wicomico River—a tributary of the Chesapeake. With this upgrade, the town helps fulfill the Bay Total Maximum Daily Load (TMDL) cleanup goals set by the EPA and state partners.
“We’re doing our part to clean up the Bay,” a town engineer said. “This isn’t just good for Delmar—it’s good for the entire region.”
Planning for Future Growth
Besides protecting the environment, the new plant also supports economic development. With more capacity and better efficiency, Delmar can now welcome new businesses and residential developments—all without overwhelming the wastewater system.
In recent years, the town has experienced modest but steady growth. As more people move to the area for its small-town charm and central location, Delmar’s leaders knew they needed to invest in infrastructure.
The project’s funding also created local construction jobs, providing a short-term economic boost while laying the foundation for long-term benefits.

Community Support and Funding
The project would not have been possible without strong community backing and interagency collaboration. Funding came from multiple sources, including:
- USDA Rural Development Program
- Maryland Department of the Environment (MDE)
- Town of Delmar capital improvement funds
This combined investment underscores the importance of modern water infrastructure in rural America. In fact, the USDA has prioritized wastewater upgrades as essential to public health and sustainable development.
According to a USDA spokesperson, “Safe, clean water is vital to any community, and Delmar’s new system is a model for others.”
Looking Ahead
As we move into 2012 and beyond, Delmar’s new wastewater treatment plant stands as a model of smart planning and sustainability. It reflects what’s possible when local leadership, environmental science, and public funding work together.
The facility reduces pollution, protects vital ecosystems, and prepares the town for future demands. More importantly, it shows that even small communities can take big steps toward cleaner, healthier water.
