Wessler Engineering is a civil and environmental engineering firm based in Indianapolis that specializes in wastewater, drinking water and stormwater projects. Western Wayne Regional Sewage District (WWRSD) has been a Wessler client for over 20 years. Wessler has worked on both the district’s collection system and wastewater treatment plant (WWTP). WWRSD serves the communities of Cambridge City, Mt. Auburn and Dublin Indiana. The Sewage District’s WWTP is located in Cambridge City and is currently rated for 0.864 million gallons per day (MGD). In additional to residential and commercial waste, the WWRSD WWTP also receives flows from the Gateway Industrial Park located just south of I-70 and SR 1. The Industrial Park’s largest discharger is Sugar Creek Packing Company (SCPC), which sends over 200,000 gallons per day of pretreated waste to the WWTP via the Industrial Park Lift Station. SCPC plans to expand its facilities in the next year and Wayne County hopes to attract other businesses to the Industrial Park, which will increase the flows seen at the WWRSD WWTP. The objective of this project is to evaluate the existing WWRSD WWTP and then determine a cost effective and appropriate design to meet the current and future wastewater needs of the community.

The first plastic recycling mill opened in the United States in 1972 as a way to reduce the environmental impact of the use of plastic. Since then millions of tons of plastics have been recycled, but the success of plastic recycling has been highly dependent on citizen participation, the type of plastic involved and the cost of fossil fuels. New approaches to manufacturing recycled plastics and to managing the supply chain are needed to increase plastic recycling.

The Tippecanoe Solid Waste Management District (TSWMD) is a government entity that provides recycling and household hazardous waste disposal to Tippecanoe County households. This is done through remote drop off bins throughout the County, as well as bins at the Transfer Station located at 2770 N 9th St, Lafayette. The cost of the recycling program has increased with an increasing population in Tippecanoe and the Chinese National Sword Policy, which lowered the market value for many recyclables in the United States. The cost of transporting materials is a barrier for many municipalities in funding a recycling program.

Transportation is a primary source of GHG emissions. Transportation is unique in that it is one of the GHG emission sectors that can be significantly influenced by the personal choices of individuals. Transportation engineering has a long history of using combinations of infrastructure and system design and policy to influence people to make choices that achieve local objectives.

West Lafayette has been utilizing the organic digester at its wastewater treatment plant to process the food waste derived from the Purdue dining courts into energy since 2009. In recent efforts to expand the intake of food waste to the digester, the West Lafayette Go Greener Commission and Purdue University Student Sustainability Council started two food waste collection programs: 1) where residents of Tippecanoe County are now able to bring their food waste to the former recycling center on River Road, and 2) where food waste is collected from fraternity and sorority houses. That food waste is then transported and processed at the wastewater treatment plant. Though the food waste stream has been steady and abundant, outdated infrastructure and a lack of funding have prevented the program from continued expansion to curb side collection and partnerships with local school corporations.

Commercial Real Estate developments are generally designed to detain stormwater for a period of time before releasing it into public systems and waterways, rarely for re-use. Detention ponds have been used for decades to store stormwater on-site at commercial properties to ease flooding and the burden of additional water on the public system. These detention ponds can take up large areas of land which cannot be built upon and do very little to reclaim water for future use.
