For Goleta (CA), Hazen developed a risk assessment methodology
and created an intuitive map to visualize the risk exposure of each major process component based on the analysis of likelihood of failure (LOF) and consequence of failure (COF) for 2,300 assets.
For the Village Creek WWTP in Jefferson County (AL), we identified $2.0M per year of operational cost saving opportunities. Many of the energy saving opportunities were low or zero cost demand management /operational changes that were implemented immediately, resulting in an annual energy cost savings of $800,000 per year.
Hazen and Sawyer assisted Sanitation District No. 1 of Kentucky with implementing a long-term asset management program for its 127 pump stations, 77 miles of force mains, air release valves, and gravity sewers.
As a part of developing a comprehensive Internal Improvement Program (IIP) for DC Water, Hazen and Sawyer evaluated their asset management practices. Our review included policies and procedures, management systems, records, reporting, and organizational structure and support services. The entire IIP projected an annual savings of approximately $30 million.
At the F. Wayne Hill WRC, our whole-plant model calibration and optimization resulted in the facility retaining its rating without capital investment and also identified $300,000 year in reduced operating costs.
Our facility-based asset management software supports the risk management and prioritization of asset renewal/replacement for any treatment plant equipment or processes.
Following the rupture of a 54 inch water main, Miami Dade Water and Sewer tasked Hazen and Sawyer with a visual and electromagnetic inspection of its prestressed concrete cylinder pipe (PCCP) throughout the county. We estimated failure rates for the next 5, 10 and 100 year periods to assess risk and helped develop a long term assessment and replacement program that includes 15 miles of prioritized inspection per year.
For the City of Houston, Hazen and Sawyer evaluated 6 wastewater lift stations, including complete structural, mechanical, electrical and instrumentation condition assessment of the facilities, force mains, and gravity sewers.
Hazen and Sawyer developed an Asset Management Program (including an optimized cleaning program and decision support tools) for Jefferson County (AL) to reduce preventable overflows and pipe failures.
Hazen and Sawyer was retained by the City of Riviera Beach (FL) Utility District to conduct a condition assessment of the existing water and wastewater infrastructure to identify renewal and replacement (R&R) needs through the year 2030.
Hillsborough County (FL) retained the services of Hazen and Sawyer to inventory and assess its water, wastewater, and reclaimed water systems, including 3,000 miles of pressure pipes. The County received a complete database of system attributes and an assessment of the useful remaining life of the system.
Aging infrastructure, shifting populations, and the need to avoid rate increases all put significant strain on utility operations. We have helped many utilities ease the strain, using quick analysis to identify ways to reduce operating costs, which can then be capitalized to make system and/or facility improvements while keeping rates neutral. Our asset management expertise includes every aspect of the water cycle, from drinking water supply infrastructure to wastewater treatment facilities.
Our asset management approach is enhanced by non-licensed, in-house software tools we develop to systematically analyze water and wastewater facilities and your entire conveyance network. These tools can identify operating strategies to get better results from your existing infrastructure, while also determining which capital improvements will bring you the best return on investment.
