YES

A factory within 30km once determined that its own treated trade effluent was a potential candidate as a source for water for fire-fighting [wf³]. The plan was to capture large quantities (1000m³?) of factory effluent in a retention tank and pump it to the site fire appliances for the purposes of extinguishing a fire. The quantities and delivery to be expected exceeded the ability of the local towm mains to supply this resource, which was available without purchase cost.

The advantage was that, as the wf³ began to drain from a burning building, it would arrive in the drainage system again, re-enter the storage tank, and become available to deliver to the fire appliance again, a potentially long-lasting and re-usible resource.

Quite what became of the idea is unknown at this time.

Why would you even want to, considering what it smells like????!!!!

Water is a scarce commodity in most countries. The system described by PwSlack is really sensible.

If clean purified water is to be used for firefighting 2 problems will occur.

1. A supply of clean water will be used possibly to the determent of people.

2. The return water may even contain worst stuff. If storage was not available the pollution will be dumped directly into water resources.

Normal sewage is biodegradable and it is not that bad unless it is treated as flowers.

One problem I have with industry (some nof them at least) is that pollutants which should be disposed of in prescribed manner is directly discharged into the sewage systems.

The heading of this question implies the question is about using sewage for irrigation sprinklers. In South Africa it is defined as a controlled activity - or irrigation with grey water (partly purified) - The quality determine the application and quantity.

Sewage contain nutrients for plants.

"If you can smell the product, you are in the product". This is something that I try to get across to students in my hazardous materials classes. If you can smell it, you are in it! It is the matter of dose (how much, or concentration, and for how long) that matters. Some gases like hydrogen sulfide, present in sewer gases, can be deadly at the right concentration and can deaden the sense of smell. At high concentrations hydrogen sulfide can kill. At low concentration, with extended exposure times, it can cause less lethal but potentially serious health problems. I would push to have the air quality checked, preferably in the evening, when the concentrations are higher, and most children will be home. Good luck.
