Key Services

1

Comprehensive Solutions for Modern Utility Infrastructure

At GRP|WEGMAN, we empower utilities to optimize their operations and enhance sustainability through advanced solutions tailored to their needs. From upgrading residential and commercial meters to implementing Advanced Metering Infrastructure (AMI) and smart grid systems, our services enable accurate billing, smarter resource management, and real-time operational insights. Additionally, we specialize in methane capture technology, transforming wastewater byproducts into renewable biogas energy or utilizing it in Combined Heat and Power (CHP) systems. These cutting-edge solutions reduce greenhouse gas emissions, enhance energy independence, and deliver measurable cost savings—all while driving environmental progress.

Remediation of Real and Apparent Water Losses

Water loss can come from two primary sources—real losses through leaks and apparent losses due to metering inaccuracies or unauthorized consumption. GRP|WEGMAN provides thorough evaluations and cutting-edge solutions to remediate these losses. Our approach helps utilities recover lost revenue, conserve valuable resources, and ensure the reliability of the water system. By focusing on both real and apparent losses, we empower your facility to operate at peak performance.

Sustainable Solutions for Biosolids and Methane Management

Efficient biosolids management and methane capture are vital components of modern wastewater operations, and GRP|WEGMAN provides the expertise to address both seamlessly. Our biosolids handling and disposal solutions focus on reducing waste volume, recovering valuable resources, and ensuring compliance with strict environmental regulations. By integrating advanced biosolids processing technologies, beyond dewatering, we can turn burdensome wastewater byproducts into valuable renewable resources. These innovations not only streamline operations and minimize environmental impact but also create opportunities for significant energy and cost savings for wastewater facilities.

5

Demand-Side Energy Conservation in Water/Wastewater Treatment

Water and wastewater treatment processes consume a significant amount of energy. Our demand-side energy conservation services are designed to reduce the energy consumption of your treatment facilities without compromising performance. We implement energy-efficient technologies such as variable speed drives, energy-optimized pumps, and process control improvements, allowing you to reduce costs while contributing to your sustainability goals.
