You may want to try adding oil eating microbes. No facility required. waste water will be 100% cleaned and ready for potable use. City municipalities use one 25# box apx $150 for a 300,000 gallon holding tank. After cleaning they pump out into their potable water into a man made lake. The multi million dollar homes have maintenance that pump the lake for ground watering purposes. Works out to be 1 cent per 20 gallons. But remember no discharge at all. 100% recycle. great for desert subsistence and all 3rd world countries.
