{ Putting water to work }

Long before it flows from a customer’s tap, our team is pioneering new approaches to enhance water quality — at a reasonable cost.

Sustainable solutions — from reservoir to tap.

Whether it’s securing ample water supplies, treating water to meet stringent drinking standards, or delivering water through an aging distribution system, we use our creativity to develop sustainable and affordable solutions. Beyond the challenges facing public water facilities, our industrial water specialists provide high-purity water and water-saving techniques that address specific industry needs.

Water supply and treatment

OBG empathizes with clients who are faced with the challenges of securing ample water supplies, treating the water to stringent drinking water standards, and delivering that water through an aging distribution system, all at a reasonable cost. Our team uses this empathy to drive creative, client-focused solutions whether the need be transforming former quarries into reservoirs, reducing chemical and energy costs with advanced treatment technologies, or pioneering new approaches to maintain water quality all the way to the customer’s tap. Our industrial water specialists go beyond the meter and provide high-purity water and water-saving techniques that address the needs of industry. By optimizing the use of water and existing water system assets, we find a way to achieve sustainable, affordable solutions.

Wastewater treatment

For more than four decades, OBG has been at the forefront of wastewater treatment, helping our clients meet increasingly stringent requirements for effluent quality and overflow abatement. Today, we’re taking the lead again with holistic approaches to recovering energy and nutrients from sewage, incorporating advanced and forward-thinking industrial treatment technologies and providing economical methods for biosolids disposal and reuse.

Our team focuses on current and upcoming regulations (persistent compounds, nutrients, trace elements, and emerging contaminants) that confront our clients and challenge existing and new manufacturing facilities to meet industrial discharge limits. The combination of our in-house applied technology and treatability laboratory, engineering, construction, and operations drives action and solutions for our clients.

Wet infrastructure

With much of the nation’s aging water, wastewater, and stormwater infrastructure continuing to fail, our team offers more self-reliant and sustainable solutions than ever before — integrating trenchless technologies that minimize community impact and reduce costs.

Case Studies

There’s a way to answer every challenge with integrity.

Our case studies best illustrate how our integrated approach blends expertise from across our company into every project while adhering to our mission in every phase.

Best working experience with any engineering firm — technically strong and highly responsive to our needs.

"Our water team thrives on exceeding client expectations which takes more than great engineering or even advanced technology. It takes true collaboration, and delivering solutions tailored to each client’s unique needs."
