Why not collect and store the wastewater for shipment to a water treatment plant?
There are five reasons why this is a poor choice: • Construction of a tank large enough to contain your run-off and the required secondary containment is expensive; a 10,000 gallon tank will cost approximately $10,000. • Such a system would probably require you to obtain permits, which can be a difficult process. • Regular inspection of the tank and monitoring wells will be necessary. In addition, the tank will have to be a double containment vessel. • It is becoming increasingly difficult to find waste treatment plants that will accept water contaminated with oil and grease. • There will be a continual shipping expense of as much as $2 per gallon and rapidly rising.
