What are air conditioning wells? They’re special wells drilled to hold wastewater used in air conditioning processes. Typically this water is contaminated with coolant, so the water must be treated before it can be reintroduced into the groundwater supply.
In the United States alone, 48 million people receive their drinking water from private or residential water wells, which are most common in rural areas.
Unconfined aquifers do not have internal pressure also known as artesian pressure. If you drill into an unconfined aquifer the water will only rise up to the top of the water table, and you’ll need a pump to get the water to the surface.
Did you know that having a water well can actually save you money on water costs? Not only can you receive several tax breaks, but you also have no water-usage fees.
Daniel Halladay, a machinist in Connecticut, designed the modern windmill. His design incorporated a tail at the back of the fan, allowing it to turn with the direction of the wind. He later improved it to regulate blade speed, taking full advantage of available winds.
Eratosthenes, an ancient Greek mathematician, used water wells to calculate the radius of the Earth back in 230 B.C.E. He did this by measuring and comparing the shadows in the wells during the summer solstice.
