The other method accepts a pre-calculated or independently determined annual water consumption value. No flow-rate conversion is applied; the consumption figure is used directly as the annual water use.

\begin{equation}\label{eq:water-reduction-other} W_{use} = C_{other}\end{equation}

Symbols

\(W_{use}\)	Annual water use \([\unit{ \gallon\per\year}]\)
\(C_{other}\)	Direct annual water consumption \([\unit{ \gallon\per\year}]\)
