Integrated Water Management

As technology advances, the world seems to shrink, increasing our awareness of how interconnected we really are. Water has always connected us all, but we’re now bringing unprecedented strain to our water supplies and the water environment. Some communities struggle to harvest enough water, others to find cost-effective ways of treating and containing the water they have. Only honoring the interconnections within the water cycle and considering all sources of water as resources will satisfy the many needs of our growing civilization.

When faced with state legislation requiring the shut down of ocean outfalls and reuse of 60 percent of the outfalls’ baseline flow for a beneficial purpose, the City of Hollywood (FL) turned to Hazen and Sawyer to develop an innovative integrated solution to address regulatory drivers. Pilot testing demonstrated that Floridan aquifer recharge could be an optimal solution in addition to potential virtual water reuse

Rather than construct a costly and environmentally adverse storm sewer system in Staten Island (NY), we developed and implemented an integrated solution that resulted in The Staten Island Bluebelt. In addition to providing cost-savings to the city, natural features have reduced flooding, improved water quality, and provided a flourishing habitat for native flora and fauna that local residents can enjoy.

To manage drought and water shortage, Hazen and Sawyer staff helped operators in Big Spring (TX), the first direct potable reuse (DPR) plant in the state, bridge the gap between conventional water and wastewater treatment, advanced treatment system operation and water distribution. Our integrated water approach allowed us to bring state-of-the art knowledge of water, wastewater, and advanced reuse to fine-tune facility operations.

Climate change and extreme weather impact all aspects of the water cycle. We worked with New York City to develop alternatives to manage turbidity events associated with extreme events. While structural alternatives were modeled and provided some benefits, the study found that a comprehensive operations support tool would achieve greater benefits with a far smaller capital investment.

Integrated water solutions require a thorough understanding of water quality risks and how to protect public and environmental health. WE&RF 13-03 Critical Control Point Assessment to Quantify Robustness and Reliability of Multiple Treatment Barriers of a DPR Scheme serves as an instrumental step in advancing the acceptance of DPR by demonstrating the robustness and reliability of multiple barriers of treatment to ensure the highest standards of water quality and assure protection of public health.

An integrated water mindset brings opportunities for innovation, business-minded operations, and resource recovery. The 60-mgd F. Wayne Hill Water Resources Center converts phosphorus to fertilizer and reduces energy costs using FOG, co-thickening, and combined heat and power facilities.

Integrated water management has always been second nature to Hazen and Sawyer. Since our founding, we’ve maintained a singular focus on water – working with communities to identify new sources, structure effective treatment, and deliver water back to the environment in a productive and mindful way. The integrated water resources management we provide improves the resiliency of watersheds to supply drinking water and turns nutrient removal into nutrient recovery, waste into energy, discharge into reuse – often while reducing operating costs and providing a multitude of environmental and societal benefits.

At Hazen and Sawyer, we can help you harness technology to fulfill your needs, while restoring and replenishing our water systems to provide sustainable supplies for future generations.
