Dimensions are in inches. <br /> Each of the two waste water capture tanks is housed within a secondary chamber that is made <br /> of reinforced concrete, having a volume that is roughly 955 gallons capacity. This is <br /> approximately 3.0 times greater than the maximum operational waste water capture tank <br /> maximum capacity volume, yielding a factor of safety of 3.0.
