<p> Once the size of cistern has been determined, it can easily be modeled in many open source and proprietary applications. For planning purposes, a RWH system could be integrated into a site plan using STEP's Treatment Train Tool.

<p> In addition to the cistern size, this watershed scale modelling requires input information about draw down time. i.e. the rate of use.  </p>
