A Spreadsheet Tool for Slow-rate Land Application System Storage Design
Goals and Objectives
LandAp is a water balance computer application that estimates storage requirements and wet-weather discharges for slow rate land application systems. It uses rainfall, reclaimed water inflow, evapotranspiration and ground water outflow to determine the amount of storage needed for times when the water cannot be applied. LandAp is mentioned in Chapter 62-610, F.A.C., (Reuse of Reclaimed Water and Land Application) as an example of an analytical means by which storage can be estimated. LandAp2010 is a spreadsheet-based modeling package that accesses an internal database of recent climate data and allows for the entry of site specific parameters to calculate water storage needs. The new LandAp2010 is easier to use, provides more information, and is adaptable to a wider set of conditions than the previous version.
