b'Value (NPV) analysis. NPV accounts for both the capital costs of the wastewater treatment system and the ongoing O&M costs. It also provides an assumption about the future salvage value of the system. This is usually zero, but sometimes parts of the infrastruc-ture have some value at their end of life cycle. By the numbers, the lowest NPV alternative will be the best long-termvalueofthewastewatertreatmentsystem.However,it shouldnt be the only metric used to decide how to proceed. There may be compelling reasons to favor low up-front capital cost sys-tems if the long-term O&M is higher and sometimes vice versa. Every project is unique, and every owner has preferences. The best part about NPV analysis is that it removes some of the emotion during decision making. The internet is full of examples about how to perform NPV analysis and a qualified wastewater professional should know how to do this for you and discuss the results.

The parks existing sewage treatment system was at capacity, restricting park service expansion and requiring costly and time-consuming maintenance.A new system was needed to handle the wastewater flow of 30,000 gal-lons per day (GPD) and meet all Texas Commission of Environmental Qual-ity standards. Design engineers selected a Delta Package Treatment Plant constructed at the factory, shipped to the project site as a self-contained unit and in-stalled without disruption to customer services. The duplicative Jellystone package plant processes wastewater via an extended aeration and oxidation process that purifies the sewage using naturally occurring bacteria. Contin-uous mixing with air feeds the biological organisms, which consume the volatile materials and convert them into water, carbon dioxide and ash. The result is a clear and odor-free effluent.Giant Goose Ranch is an 800-acre reclaimed strip mine property in Fulton County, Ill. The Herman Brothers family wanted to update the existing lake-side campground into a world-class family vacation destination. To do so, they needed a new wastewater treatment design to serve clusters of resort cabins, campsites, beach houses, a store and a banquet hall. Inconsistent soils, numerous lakes, drastic elevation changes and stringent new code requirements challenged system designers. To preserve the pristine environment, wastewater system designers se-lected water recycling membrane bioreactor systems (MBR) installed inside infiltrator plastic tanks. The numerous MBRs are either 500- or 1,000-GPD units with single units for individual cabins and 1,000-GPD MBRs to serve clusters of cabins. EZflow geosynthetic aggregate bundles were used for the treated effluent dispersal fields, further protecting the environment by eliminating the need for heavy trucking of stone to the site.WCM Real Log Park Model Cabins Real Rustic Log CabinsTurn-Key!Durable and AppealingAmish CraftsmanshipPays Off Within 1-3 YearsPark Model Cabins Starting at $29,900Located in Lancaster, PA Infiltrator tanks at Giant Goose Ranch. 717-445-5522www.LancasterLogCabins.com26 October 2021Woodalls Campground Magazine'
