Book Description
A field project demonstrated the feasibility of renovating secondary sewage effluent by ground water recharge with infiltration basins. Maximum loading rates were obtained. With the schedules the system could infiltrate 300-400 ft/year using a water depth of 1 ft. Grassed basins had higher infiltration rates, and a gravel covered basin had a lower infiltration rate than a bare soil basin. Essentially complete removal of BOD and fecal coliform, and significant removal of phosphorus, nitrogen and fluoride were obtained. Hydraulic properties of the aquifer were evaluated by analog from the response of piezometric heads in the ground-water system to infiltration. These properties were then used in the design of a prototype system, which would yield renovated water at an estimated total cost of about $5 per acre-foot at the pump.

Book Description
This 300+ page study is based on data from 30 college sports arenas, about half of which are Division I colleges. The report looks closely on how these colleges have renovated their sports arenas and what their plans are for the future. The study helps college sports planners and their suppliers to answer questions such as: What has been the economic impact of arena renovations? What percentage of colleges have a line item in their capital budget for their arenas? How much have colleges spent on arena renovations and what will they spend in the near future? What are they renovating? Seating? Playing surfaces? Locker rooms? VIP fan facilities or luxury boxes? Stadium seating? Weight rooms? Stadium lighting or scoreboards? In-stadium video?
