If You're Going to Live in the Country

The driven or artesian well has two points that makes it worth the cost. There is no question of purity or of quantity. It taps subterranean water which is unaffected by local causes of contamination or by drought.

The kind of water system, like the supply, is governed by geography and geology. If there happens to be a spring on a nearby hillside somewhat higher than the house, nature has provided the cheapest and simplest system. A pipe line and storage tank are all that are needed. Gravity does the rest. On the other hand, if the spring is on the same level or lower than the house, a pump must be added to the equipment to force the water into the pressure tank and out of the faucets. If the spring has a large flow and adequate drainage, a water ram is advisable. With this hydraulic machine, three-quarters of the water that flows into it is used to force the balance into the storage tank. The expense of operation is nothing and as water rams and pumps cost about the same, such an installation has much to recommend it.

When the search for water goes below ground, one must reckon with geology. What lies below the turf is the deciding factor. If it is sand and gravel with a high water table (the level of subterranean water), an excellent well can be had cheaply. The practice is either to bore through to the water table with a man-operated auger and then insert the pipe, or to drive the latter down with a heavy sledge hammer. In either case, water is but a few feet below ground and a shallow-well pump, which can raise water twenty-two feet by suction, will be adequate.

There are two types of well to be considered with less favorable subsoil formations—the shallow and the artesian. With the former (known to country people as a dug well) a shaft from six to ten feet across is dug with pick and shovel until adequate water is reached. Then the shaft is lined with stone laid without cement or mortar up to a few feet from the top. This allows water from the surrounding area to seep into the well where it is retained until it is drawn upward by the pump. It is obvious that a well of this type cannot be built through ledge or solid rock. In fact, unusually large boulders sometimes force diggers to abandon a shaft and start afresh. An old house with two or three of these shallow wells on the premises serves notice on the prospective buyer that repeated and probably unsuccessful attempts have been made to find a well that does not go dry.

Dug wells are seldom deeper than fifty feet; the majority are but little beyond twenty-two feet, the suction limit for a shallow-well pump. As is obvious from their construction, they depend on the water in the upper layers of the subsoil and so are more readily affected by dry weather. Although not drought-proof like the artesian, a dug well, which costs much less, can be an excellent water source and supply amazingly large quantities of water.

We have lived for ten years in a house served by a shallow well credited with being never failing and it has faithfully lived up to its reputation, even through the driest of seasons. Once, however, it made real trouble. Over it stood a picturesque latticed well house. On one of the beams a pair of robins nested annually. In the middle of the third summer the water developed a queer flavor. It steadily grew stronger until one night the steam arising from a hot bath caused the pajama-clad head of the house to seize a flashlight and move hastily to the well house. One beam of light disclosed the horrid truth. Floating in the water far below were two very dead fledglings.

The next day a well cleaner collected twenty-five dollars for removing the birds and pumping out the well. He also gave some excellent advice which was followed promptly. The well house, picturesque though it was, gave way to a substantial masonry curbing equipped with a stout wire cover. The peace of mind so gained has more than offset the trifling expense. No longer need one peer fearfully down a twenty-five foot shaft when a pet cat fails to show up for a meal, or shoo away from the spot the over-inquisitive offspring of visiting friends.

The drilled well, against which there is no possible argument save that of cost, is made by boring a hole in the ground with a powerful apparatus until sufficient subterranean water is reached. There are two methods, the chop and the core drill. With the former, a cutting tool exactly like the drill used to drive holes in rocks for blasting, only larger, cuts a circular hole downward. The boom of the drilling rig as it raises and drops the drill provides the necessary impact. With the core method, as its name implies, a hollow boring drill cuts its way aided by steel shot and a flow of water forced through the pipe that rotates the cutting tool.

With either method the results are the same. Sooner or later the drill will reach an underground water course of sufficient size to give an ample flow. As such drilling is done on a charge of three to five dollars a foot, the owner, of course, hopes for sooner. Except where there is an underlying stratum of sand or gravel beneath hard pan, the drill has to go through rock. How far depends on the kind. Sandstone is the best water producer; limestone yields very hard water. Again, drilling through till (a heterogeneous mixture of clay, gravel, and boulders) may or may not locate water readily depending on how densely it is packed. The rocks known as gneiss and schist are readily bored and are considered fair water bearers.

Granite is bad news. It means slow work and a deep and expensive well. It is one of the hardest rocks with little water content. The only hope is that the drill will strike a vein flowing through a fissure. Whether it will be at fifty or 500 feet is a pure matter of luck. A dry well at 100 feet may become a gusher at 105 delivering twenty gallons to the minute, or it may stay dry for another two to five hundred feet.
