A Public / Private Partnership Equates To A Win-Win-Win

World Water Works, Inc. (WWW), a leading designer and manufacturer of wastewater treatment solutions, has been selected to provide its Ideal MBBR-DAF technology by Hopewell Regional Wastewater Treatment Facility (HRWTF), a 27 million gallons per day (MGD) facility. This selection came through a design/build public/private partnership between the City of Hopewell, and the team of HDR Engineering (HDR), PC Construction (PC), Heyward Inc., and World Water Works, Inc. The combination of the MBBR and DAF technologies is particularly well suited for this situation and highlights WWW’s core expertise and will bring the total nitrogen (TN) waste load of the Hopewell Regional Wastewater Treatment Facility (HRWTF) into compliance with local regulations.

HRWTF has a unique situation where the source of more than 80% of its wastewater comes from industry some of which contains known toxins to Ammonia Oxidizing Bacteria (AOBs) and Nitrite Oxidizing Bacteria (NOBs). AOBs and NOBs are responsible for the traditional nitrification / denitrification process of removing nitrogen from wastewater. To solve the problem, HRWTF conducted an extensive evaluation and pilot treatability study of various technologies including WWW’s advanced Moving Bed Biofilm Reactor (MBBR) coupled to a high rate Dissolved Air Flotation (DAF) system, the Ideal MBBR-DAF system. After over six months of pilot testing, it was clear that the Ideal MBBRDAF system led the field by consistently bringing TN levels of the facility to the future targets while being very robust against the harder to degrade industrial wastewater sources being treated. Furthermore, WWW and HDR developed a creative design to reduce capex and provide a robust solution.

To provide a timely and cost effective solution to HRWTF; HDR, PC, Heyward and WWW teamed together to present a Public/Private Partnership (PPP) option. HRWTF evaluated this option thoroughly and through independent parties and found that the option not only offered the ability to implement the project faster, but also at a substantially lower cost than the traditional design-bid-build path. “This PPP is a win-win-win,” explains Daniel Dair, Technical Manager at WWW. “HRWTF gets a state of the art system with a binding performance guarantee from one source, the price is not only lower than anticipated, it is also guaranteed, and the local water ways and Chesapeake Bay win with better water quality sooner.” The project is in full swing and is expected to be completed by 2016.

About Hopewell Regional Wastewater Treatment Facility
HRWTF is a secondary wastewater treatment plant that currently treats an annual average flow of approximately 27 million gallons per day (MGD) of combined wastewater from local industries and domestic sources. In 1977 when the plant started operation, the facility was designed to treat for Biochemical Oxygen Demand (BOD) and the removal of Total Suspended Solids (TSS) and employed the use of Pure Oxygen. Since the 70’s the facility has achieved it treatment goals for BOD/TSS however treatment regulations have changed requiring the removal of nutrients. HRWTF has consistently been below it’s waste load allocations for phosphorous, however it has only, in the recent years, been able to meet nitrogen allocations through the purchase of nitrogen credits under the Nutrient Credit Exchange Program.
