The Santa Clara Valley Water District has selected Black & Veatch to lead an urgent seismic retrofit programme for Anderson Dam in northern California.
The $150M ($94M) programme will enable the water district to again use the dam for maximum water supply storage when completed in 2018.
Following a seismic stability evaluation in 2011, the water district implemented self-imposed water level restrictions on the dam, which were later approved by regulators. The evaluation revealed the dam is subject to significant damage if a large earthquake were to occur nearby. To protect downstream communities from the potential uncontrolled release of water, the reservoir will operate at 68% capacity until improvements are completed.
As programme manager, Black & Veatch will work with a team of local small business subcontractors to oversee planning, permitting, design and construction of improvements for the dam.
