Yes, it is.
gray water is the waste water from washing.
The gray water pipe is UPVC .
Waste water from toilets goes to a waste water treatment plant. So called gray water from showers and bathroom sinks goes straight overboard. Food waste and packing materials gets burned in an incinerator. Other incombustible materials gets compressed and send to a plant ashore. Oil and sludge in the engine room normally get separated from the water and the sludge gets burned in the incinerator and the clean water gets pumped overboard.
The genetic evidence is quite clear on this question. With great certainty we can say the domestic dog has only the gray wolf as ancestor.
DEPENDS, but mostly domestic.
Brain tissue is called gray matter because it is gray.
Probably any tint or shade of grey.

All domestic dogs as well as the dingo of Australia are the same species as the gray wolf.
They are hunted for food, medicine, and hides, competition for water and food with people and domestic livestock, and loss of habitat.

Gray water is, in essence, used water (like dish water, shower/bath water). This water can be diverted to flow into one's yard or garden, making use of this gray water instead of letting this valuable resource waste away in a sewer or septic! Gray water is clean, gently-used water. To make the most of it, do not use soaps or detergents with harmful chemicals. Look for all natural or bio-degradable products instead.
