Increased Capacity Raising the dam boosted the reservoir’s capacity from 90,000 acre-feet to approximately 242,000 acre-feet of combined emergency and carryover water storage. This secures safe and reliable water availability to help support the region’s $150 billion economy and the quality of life of its 3 million residents. The addition of 152,000 acre-feet of water storage capacity is enough to serve more than 300,000 homes for a year. Two-thirds of the new capacity will capture surplus water during wet seasons for use during subsequent dry years. The remaining one-third of the new storage will store water for use if an emergency cuts off the San Diego region’s imported supply. The $416 million roller-compacted concrete (RCC) dam raise to the current height of 337 feet marked the largest raise of a concrete dam in the United States and the highest raise in the world using the RCC method. It was also the largest single increase in water storage in the San Diego region’s history. The dam raise project was completed in July 2014. Other features associated with the San Vicente Dam Raise project included construction of a low-level outlet works through the existing dam, construction of an outlet works intake tower on the upstream face of the dam, tunneling through the right abutment, installation of outlet works conduits, and construction of a downstream control facility. Nearly all of the concrete for the raise was produced on site with material mined from the hillsides, saving approximately 100,000 delivery truck trips through the local community. Black & Veatch was also involved in other segments of the overall ESP, such as the county’s state-of-the-art pump station, which can help to move 440 cubic feet per second of water from the San Vicente Reservoir to an SDCWA aqueduct. The entire ESP project has been named the 2016 United States Society on Dams Award of Excellence winner in the Completed Project category.

Asia Pacific's 'Digital Utilities' of the Future In addition to environmental and social challenges, water utilities in Asia Pacific are faced with the complexities of non-revenue water, underdeveloped or aging water infrastructure and growing expenditure. Digital transformation may offer the water industry the opportunity to provide reliable and sustainable water supply by optimizing distribution systems, treatment efficiency and asset management. Energy Planning Offers Efficiency, Cost Savings, Resilience Down the Road As energy costs continue to rise and more states adopt regulatory incentives and disincentives that drive large-scale sustainability and efficiency efforts, it is expected that utilities will become more aggressive in their approach to managing energy. Technology, Trading Offer Opportunity for Managing Nutrient Discharge Nutrient pollution and the resulting excess of nutrients in waterbodies continues to plague aquatic environments around the world, threatening waterways, fish and plant life – and even public health. The runoff of phosphate and nitrogen from farming, stormwater, wastewater treatment plant discharges and other sources into waterbodies continues to unbalance ecosystems, resulting in toxic algal blooms and hypoxic dead zones.

Ultimately, the department set out to double the Tai Po Water Treatment Works’ production. Achieving that goal was an amazing feat in itself, but the department saw beyond the infrastructure to boldly address the equally complex challenge of safe and sustainable treatment. Lifting the Burdens of Capital Improvement Programs For more than 20 years, Black & Veatch worked with the Winston-Salem/Forsyth County Utility Commission to upgrade its wastewater treatment system on a project-by-project basis. There were many short-term wins, but resilience dated master plan made the long-term a bit less clear. The real win, and biggest cost savings, required a different approach. Water Reuse Provides Cost Savings to City, Avocado Farmers The city of Escondido, Calif., had converging challenges. It had too much wastewater and not enough potable water. The answer: water reuse. A Wastewater Treatment Plant that Pays for Itself Black & Veatch is the designer and builder of a new, $35 million solids treatment system for the Liverpool Wastewater Treatment Plant in Medina County, Ohio. The system provides energy performance savings and other sustainable benefits through an innovative Design-Build Performance Contract. As a result, the county expects to be able to pay for the new system without increasing customer rates.
