With Black & Veatch’s help, many facilities are capturing biosolids energy and converting it to a marketable product. As a result, the facilities are getting the benefits of lower operational costs. We refer to the growing waste-to-energy industry as “resource recovery” rather than waste management. Anaerobic digestion is a well-established method of dealing with liquid and solid organic waste. The process generates biogas that can be used as a renewable energy source.
Fueled by our dual expertise in the water and energy areas, our teams can help water clients implement additional renewable energy strategies, including small-scale hydropower and solar approaches.
Black & Veatch also offers Energy Savings Performance Contracting (ESPC). An ESPC or performance contract is an agreement for the scope development, design and construction of efficiency improvements. These improvements are created to deliver significant energy and operational cost savings – with performance of the improvements and their savings guaranteed. Projects are funded by reallocating the guaranteed savings to the utility’s budget, with no impact on the utility’s capital budget or rates. The excess savings can be put to work on other needs.
In building water and wastewater infrastructure, Black & Veatch is the only energy services company (ESCO) that can perform each step – feasibility study, design-build delivery option, and monitoring and verification of performance. This means clients have a single point of responsibility for the entire project.
Energy Savings Contracting
Frederick Winchester Service Authority’s Opequon Water Reclamation Facility helps to preserve water quality in Chesapeake Bay, meeting requirements for nitrogen and phosphorus removal. After a recent upgrade to reach new, more stringent nutrient limits of 4mg/L TN and 0.3 mg/L TP, the utility faced increased operating costs in addition to the significant additional debt service.
Davyhulme Sludge Balanced Asset Programme
Urmston, Manchester, United Kingdom
To safeguard recycling to agriculture and give greater flexibility to plant operations, United Utilities Water is constructing an advanced sludge treatment facility at Davyhulme Wastewater Treatment Works. The plant will treat site sludge and receive additional sludge from other contributing WwTW sites.
Glencorse Water Treatment Works
Edinburgh, Scotland, United Kingdom
Minimizing the environmental impact was central to the project. The ability to use gravity, rather than energy-intensive pumps, to drive flows from the treatment works to Scottish Water’s customers dictated the choice of the site. An additional environmental benefit of the gravity flow is the ability to generate electricity through the installation of a turbine that harnesses the water’s kinetic energy, powering the facility.Read More

Energy Savings Performance Contracting Delivers Maximum Flexibility Along with Upgrades
Energy Savings Performance Contracting is generally understood as a delivery approach to improve operating efficiency and address capital needs while minimizing financial impact to the utility. But it also delivers flexibility for those who understand it. Although it isn’t a panacea, an Energy Savings Performance Contract that is properly applied can be a powerful way to address the issues facing the modern utility.
