The existing 4-million gallon water tanks built in the 1940’s at Vandenberg Air Force base were leaking and needed to be replaced with new tanks and a manifold piping system to support the base’s water supply. Soltek demolished and recycled the existing, leaking concrete reservoir tanks and constructed two new concrete pre-stressed, steel cable 4-million gallon water reservoir tanks and a new CMU pump house structure. All usable structure demolition materials and soil were recycled and used on site.
