Wastewater Reuse Project Will Boost Florida’s Water Sustainability
Advanced Treatment Plant the Largest of Its Kind in the State
(Hollywood, FL – May 27, 2009) – With the help of Hazen and Sawyer and another national firm, the Miami-Dade Water and Sewer Department is working to recharge the Biscayne Aquifer with wastewater that has been treated to meet drinking water standards. The Biscayne Aquifer is the primary drinking water source for South Florida residents.
A recent television news story by WPLG, Local 10 News in Miami, Florida, summarized the progress being made: http://www.justnews.com/video/19522086/index.html
The 21-mgd South District Water Reclamation Plant (SDWRP) design includes an advanced wastewater treatment approach that will replenish the Biscayne Aquifer via rapid infiltration, in which the treated effluent percolates through the soil down to the groundwater level. In addition to evaluating, selecting, and designing the treatment process, which included the pilot testing, Hazen and Sawyer is contributing to the development of regulatory standards for implementation and long term operation of the project. This project builds on an upgrade to the South District Wastewater Treatment Plant (SDWWTP) which adds High Level Disinfection (HLD) to the existing pure oxygen secondary treatment plant. Hazen and Sawyer is working with Department staff to provide program management, design and construction management services for the HLD project. The SDWRP is adjacent to the SDWWTP and will treat secondary effluent from the SDWWTP to extremely high water quality levels. (Process diagram on the following page)
Hazen and Sawyer has been at the forefront of water reuse program planning, design and research for the last twenty years, leading projects all along the Atlantic coast as far north as Connecticut. In addition to the ground reapplication of effluent to recharge natural resources, Hazen and Sawyer’s work has helped clients replace the freshwater sources typically used for power generation with reclaimed water, thus conserving the water resource, the associated costs of treatment and transmission, as well as the associated greenhouse gas emissions.
For more than half a century, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater collection and treatment. Since our founding in 1951, we have grown in size to over 740 employees in 26 offices.
