RETTEW performed a study to evaluate the adequacy of the existing Masonic Village Elizabethtown campus water supply, treatment, and distribution systems. The study also included current regulatory permits for existing and additional residents and employees projected to be added over the next 15 years. The issues evaluated included the ability of the wells to provide the expected maximum day demand, the adequacy of the 30-day average water withdrawal (AWW) limit established by the Susquehanna River Basin Commission (SRBC), and the adequacy of the current consumptive use limit established by SRBC.

As part of the study, RETTEW evaluated the water storage volume required to meet the daily operational, fire, and emergency needs of the Masonic Village campus. RETTEW developed an overall system hydraulic model to evaluate the distribution system capacity and its ability to provide adequate system flows and pressures, for both domestic and fire flows. The three water supply wells and treatment system will be able to supply adequate water flows to satisfy the projected maximum daily demand for the next 15 years of estimated growth.
