CHAPTER IX The Question of Water Supply

Previous

Whether one lives in the country or the city, geology and geography govern the source of the water that flows from the tap. Cities go miles for an adequate, pure water supply and have been doing so since the days of the Caesars. Such systems involve thousands of acres and millions of dollars for water sheds, reservoirs, dams, pipe lines, and purifying plants.

The country place is a miniature municipality with its own water system. The latter need not be elaborate or expensive but it must be adequate. Nothing disrupts a family so quickly and completely as water shortage. Personally, we would far rather see our family hungry and in rags than again curtail its baths and showers. "We can be careful and only use what is necessary," sounds easy but before long everybody is against father. He is mean and unreasonable. Save the water, indeed! It is all his fault. He should have known the supply would fail when he bought the place. A moron could see it was not large enough. A six weeks' drought? Well, what of it!

Meanwhile water diviners, well diggers and drillers add gall and wormwood to the situation. "Oh yes, that well always did go dry about this time of year. Saving the water wouldn't make any difference. Better not bother with it but dig or drill a new one." Expense? Why quibble about that when the peace of one's family is at stake. There is, of course, only one outcome. A broken and chastened man soon makes the best terms he can with one of his tormentors. If he is wise it will be with the advocate of the driven well. That solves for all time any question of water supply.

Before deciding on a source, however, consider what the daily needs will be. From long observation, it has been found that the average country place requires fifty gallons of water a day for each member of the family, servants included. Then allow for two extra people so that the occasional guest, whose knowledge of water systems begins and ends with the turning of a faucet, will not unduly deplete the supply. For example, a family of seven should have a daily water supply of from 400 to 500 gallons depending on how much entertaining is done and how extensive are the outdoor uses. This allowance will be ample for toilets, baths, kitchen and laundry, as well as for moderate watering of the garden and lawn. Of course, if cars are to be washed regularly, fifty gallons should be added to the daily demand. If there is a swimming pool, its capacity should be figured by cubical content multiplied by seven and one-half (the number of gallons to the cubic foot) and allowance made for from fifteen to twenty-five per cent fresh water daily.

The daily production of a spring or drilled well can be easily gauged. A flow of one gallon a minute produces 1,440 gallons in twenty-four hours. In other words, a flow of ten gallons a minute means 14,400 gallons a day which, at fifteen gallons a bath or shower, is enough water to wash a regiment from the colonel to the newest recruit.

Estimating the daily production of a shallow, dug well is more difficult. The number of gallons standing in it can be obtained by using the mathematical formula for the contents of a cylinder, but only observation will tell how quickly the well replenishes itself when pumped dry. By long experience, however, country plumbers have found that if such a well contains five feet of water in extremely dry weather, it can be relied upon for the needed fifty gallons a day each for a family of seven with enough over for safety.

In fact, with all water sources except an artesian or driven well, the question always is, will it last during an abnormally rainless season? Never-failing springs and wells that never go dry are institutions in any countryside. So consult some of the oldest inhabitants. They know and if they give your well or spring a good character, the chances are that even the most exacting of families will find such a water supply adequate. Whether it is pure or not is another matter but one that can easily be determined by sending a sample to your state health department or a bacteriological laboratory. That this should be done before such water is used for drinking purposes goes without saying.

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.

Tales of well drilling are many and varied. Good pure water has been found at fifteen feet. In New Hampshire there is a well 900 feet deep that gushes so powerfully that it is capped and still flows at forty pounds pressure. It supplies an elaborate country place and a large stock farm. It is performances like these that indicate the water is there if one will just keep on drilling and paying until it is reached.

Where to locate a well is very much a matter of guess. Even in the Sahara Desert there is water. How far down is the question. For generations much faith was placed in diviners. They were supposedly endowed with some occult talent that enabled them to pick a sure spot for water. They were known for miles around and were summoned when a new homestead was under consideration. With a forked hazel wand held in both hands, such an one would pace solemnly around until the stick gave a convulsive twist downward. This indicated that water was directly beneath. The spot would be reverently marked; the diviner would depart and the well diggers who had followed his performance with proper awe would begin work. As the ceremony failed to stipulate just how far down the precious liquid was, a successful well was presumably the result. The prowess of the well diviner is acclaimed even today by some people, although scientific investigation has proved that his services are worth just about as much as those of a witch doctor.

After the country home owner has attended to the little matter of a well, be it old or new, dug or drilled, the next step is installing a pump. If the water level is less than twenty feet below ground, a shallow-well pump will be perfectly adequate and as it is much less expensive than the more elaborate deep-well pump, we recommend its use if possible. Most plumbers invariably advise the deep-well pump, especially for driven wells. They do this in all honesty and with no ulterior motive. There is always a bare chance that the water level may drop below the suction limit of the shallow pump under abnormal pressure. If it does, an irate customer can descend on the luckless installer of the less expensive pump and cause general unpleasantness if not loss of custom.

The difference between these two kinds of pump, aside from price, is that with a shallow-well one, suction is produced in the cylinder of the pump itself, while the deep-well pump has its plunger and cylinder at the bottom of the well. Water is forced up the pipe by the up and down movement of the plunger within the cylinder. This plunger is connected to a geared wheel by the well-rod that extends downward from well-head to cylinder in the center of the same pipe through which the water is forced upward. Because of its design, a deep-well pump must always be located directly above the well itself. With a suction pump, on the other hand, the pipe from well to pump may bend and turn to suit conditions. These should be as few as possible since each right-angle bend of the pipe reduces the pump's suction power one foot.

As for motive power, electricity has distinct advantages over all other means. The switch operated by pressure starts the pump when the supply of water in the storage tank drops below a certain level, and also stops it when the proper volume has been reached. (Ten pounds to start the pump and forty or fifty to stop it are the usual adjustments.) A nice little refinement here is the installation of a third faucet at either kitchen or pantry sink, piped direct to the pump. Turn this and fresh water flows from the well itself, thus consoling any sentimentalist with visions of a dripping moss-covered bucket. Also water so drawn seldom needs to be iced. In summer if there are signs of a thunder storm it is wise to open this same faucet. It starts the pump and that automatically continues until the storage tank is full. Then, if electric service is cut off by the storm, the household will have ample water until the damage has been repaired.

If the country home owner happens to live beyond reach of an electric light system, he can put in his own plant, use a gasoline engine for motive power or even a hand pump. A gasoline engine should, of course, be located in an outbuilding and the exhaust pipe must extend into open air because of the deadly fumes of carbon monoxide gas. The hand pump is, of course, the simplest and there are several excellent ones to be had. They are not as practical as they sound, however.

When we first bought our own country place we installed a very good one as there was then no electricity in the locality. It worked excellently—when any one could be found to man it. Handy men hired for odd jobs around the grounds took it on for a set sum per time. The labor turnover was unprecedented. One by one they either resigned within a week or somehow managed to "forget all about that pumping job." Members of the family pressed into service straightway became ardent water savers, and guests who volunteered gallantly somehow never, never came again. Yet it was not an exhausting or complicated task. It was simply so monotonous that it wore down the most phlegmatic nature. So the rural householder will do well to remember that, after all, this is a machine age and govern himself accordingly.

As for the storage tank, the modern practice is to place it under ground or in the cellar. The old custom of putting it in the attic had distinct disadvantages when an overflow or a leak occurred and either stained the ceilings or sent them crashing down on furniture and possibly occupants of the rooms below.

The best water system, however, cannot cope with faucets thoughtlessly left running. Even the largest tank will eventually become empty and then there will be water for no one until the pump has replenished the supply. "Waste not, want not" is an excellent motto for dwellers in the country, especially where water is concerned.
