Fair Enough
I stand corrected.I never thought about the pump out not being attached to a large municipal waste treatment system.Obviously the impact of a couple of gallons of diesel will depend on the size of the system that it is introduced to.I'll also offer that a well designed treatment system should not be brought to it's knees by someone accidentally putting a couple of gallons of HC into the system. In a perfect world no one would ever launder oil soaked rags or clothing and cooking oil would never get poured down the sink. In the real world these things happen on a regular basis. Treatment system designers must have taken this into consideration. There are organisms that feed on HC that get used to remove HC from contaminated soil, surely some provision is made for separating or treating small ammounts of HC in the waste water stream?It is also a fact that more than 2 gallons of HC gets washed of the roads and into the drains every time it rains. It is not right, I don't think it is good for the planet, but it does happen. How many cities process water from the storm drains? Would a system that processes water in the strom drains even notice the extra fuel?Like I said before, although not an ideal solution, putting the 20% of 2 gallons (less than two quarts) that remain in the holding tank into the waste treatment system shouldn't be a disaster.However, if 51.2 ounces of diesel fuel in the waste system is enough to kill the system, I differ to those that have that information at hand.For a real wake up call, if the pumpout is in Victoria BC Canada, it will get pumped untreated into the sea anyway.
