Excellent diagnosis Daniel. Each of the mentioned items must be dealt with. 1. when installing turf the soil must be deeper and layered. a) to hold the moisture longer a b) allow excess to drain slowly in a semi enclosed system. 2. Must incorporate a microbial balance and a nutritional balance in that soil. This sets the stage for efficient biological mineralization. 3. The water being used must not in any way have chlorine in it. This defeats the purpose of a strong turf that looks good and mainly takes care of itself. Stadiums have a very large surface area. The collection, storage and use of rain water must be part of the original design reducing the need for potable drinking water from public use. Cost a heck of a lot less also. You do have a choice of which soil to use. The NEW modern technology ( has been used for 4.5 billion years) is called bioremediation.  Nature has 2 microbial main groups for compound reduction to its elemental/nutritional state.  DNA and RNA.  DNA most are familiar with: bacteria and fungi. Bacteria creates beneficial proteins. Fungi acts as a transport system for these nutrients.  But in order to reduce to elemental state requires the RNA microbial group. That name is Archaea. When using this no odor, all pathogens and toxins are eliminated, and up to 50% water and fertilizing reduction. Setting up an onsite recycling center that makes its own compost/soil nutrient product will help your soil, eliminate event waste, and improve profit margins. In sports like nature you have to work the soil to gain some ground. Sorry, no hail marys in nature. In the words of Yoda. " Do, not do. No try ! ".
