The City of Sierra Madre, CA, was challenged with replacing an existing water storage tank with two new tanks but had only one piece of land available. Construction of a 2.8 million gallon prestressed concrete tank with a concentric concrete inner wall inside an outer tank solved the challenge. This tank-within-a-tank project allowed for reservoir separation while accommodating two tanks on one site.
