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.

SEWAGE SAFETY

_CHAPTER X_

SEWAGE SAFETY

Among the problems which his miniature munic.i.p.ality brings to the country house owner is the unromantic but necessary one of sewage disposal. In a suburban area it is merely a matter of connecting the house to the street main and paying higher taxes. With the country house, each owner must cope with the question for himself. He cannot leave it to chance or delude himself that any old system will serve.

Some hot August day when his house is filled with guests, the makeshift disposal system will suddenly cease to function and an otherwise tactful guest will ask whether that queer smell is just part of the regular country air or what.

Of course, n.o.body thinks of disposing of household waste by piping it to a brook or letting it flow down a sandy side hill some distance from the house. Those were the methods of the ignorant and unscientific past. The means of disposal recommended by sanitary experts are those in which the wastes undergo a bacterial fermentation which finally renders the sewage odorless and harmless. It can be accomplished by a septic tank or a tight cesspool. The latter with its two chambers is really a variety of the septic tank itself. The first vault is built of stone or brick laid in mortar and covered with a coat of waterproof cement. With both supply and overflow pipes below the normal level of the liquids, beneficial fermentation takes place in this compartment before the liquids pa.s.s over into the second chamber from which they gradually seep into the ground. Such an installation calls for more excavation and construction than a septic tank and, since it accomplishes nothing that cannot be done with the latter, is only used where there is not enough ground area for the disposal fields of a septic tank.

The latter is an air-tight cylindrical or oblong container placed below ground, in which raw sewage purifies itself by the inherent bacteria. The first stage takes place within the tank and the second in the porous pipes that const.i.tute the disposal fields. From the moment household wastes enter the tank, fermentation begins its work of reducing them from noisome sewage to harmless water. Both intake and outlet pipes extend below the level of the contents, with a baffle plate across the center which prevents direct outward flow. The heavy solids sink to the bottom and anaerobic bacteria, which develop only where there is no oxygen, breed rapidly and break these up so that they rise to the top and provide the ever present sc.u.m which excludes all air and stimulates fermentation of the entire content. Meanwhile, liquid from the tank is flowing into the disposal fields, which are porous land tile laid in shallow trenches and covered with earth and sod. Here some air is present and aerobic bacteria (those which thrive where there is oxygen) develop and complete the process of transforming the wastes into clear water.

Installing such a system is neither expensive nor complicated. The tank itself should be large enough to hold the sewage of a household for twenty-four hours. It can be bought ready to install, or built of brick or concrete. Ready-made tanks are to be had of steel, concrete, or vitrified tile. We installed one of steel (which is the cheapest) some ten years ago and have found it most satisfactory. When it was delivered, two husky truck-men placed it at the edge of the pit prepared for it by the waiting plumber. They exhibited some curiosity and the plumber explained briefly about the bacteria and its action.

"You mean one of these here bugs is into it already?" asked one of them as he applied an awe-struck eye to the aperture in the top. He apparently expected to find an insect akin to a full-size c.o.c.kroach running around inside, and either decided the light was poor or that the plumber was a first-cla.s.s liar, for he went off shaking his head doubtfully.

The size of tank and length of disposal field is entirely a matter of size of household. On an average, the daily volume can be reckoned on the basis of fifty gallons per person and, for every fifty gallons of tank capacity, there should be thirty feet of disposal field. Thus, for a family of eight, a tank of five hundred gallons' capacity connected with a disposal field of three hundred feet will be ample, allowing for guests as well.

In installing this system, the tank itself can be as near the house as ten or fifteen feet but the piping connecting it with the soil line of the plumbing should be water tight. The best way is to use four-inch cast iron pipe, calking all joints with oak.u.m and lead. At a convenient point between house and tank, this line of pipe should have a "clean-out" fitting so that rags, solidified grease, or other substances that might block it can be removed. Sometimes vitrified tile with cemented joints is used instead of cast-iron pipe; but it has the distinct disadvantage that, if the rootlets of trees or large shrubs, attracted by the water, find so much as a pin hole in the cement, they will grow through and finally clog the pipe.

From the tank to the disposal field, the first three or four lengths of pipe should be glazed tile with tight cement joints. From these on, three or four inch porous land tile laid in shallow trenches is used.

For proper action, the trenches of the field should be not over eighteen inches deep so that the warmth and evaporation of the sun may be effective. Also in digging these trenches, there should be a slight grade away from the outlet of the tank. An inch to every ten feet is adequate.

The bottom of the trenches is covered with a two-inch layer of medium-sized crushed stone or clean gravel. On this rest the land tile, and the joints are covered with roofing paper to prevent bits of stone or gravel from lodging within the pipe. The latter is covered two inches deep with more stone or gravel and over all go lengths of roofing paper cut slightly wider than the trench so that, when in place, the paper arches and fits tightly to the sides. The purpose of the stone or gravel is to facilitate water seepage from tile to ground while the roofing paper cover prevents silt from reducing the seepage.

At the terminus of each trench is a leaching pool, built by digging a hole about three feet across and five feet deep. It is filled with crushed stone or small rocks to the level of the trench piping. Over it, before replacing the dirt, goes another piece of roofing paper.

Into these pools drain what water has not seeped away in flowing from the tank.

As can be seen from the foregoing description, the fermentation and bacterial action that takes place in a properly built septic tank system is automatic and needs no attention, although every second or third year it is advisable to remove the mud-like sediment from the tank. Otherwise, the latter's capacity gradually diminishes.

The steps involved in building such a system are so simple that, while the services of a plumber are advisable, it is possible for an intelligent handy man to do the work. Be sure, however, that he realizes that each step is important and necessary. We knew of one otherwise capable workman who calmly omitted the crushed stone and gravel in the tile trenches. The system worked well for about four years. Then, one warm and sticky day in July, it ceased to function. A plumber demonstrated that the tiles were clogged with silt because the bed of crushed stone had been forgotten. For a week the house was sewerless while the careless short cut was remedied. The household had but two alternatives, take a vacation or go primitive.

However, if a properly installed system fails to work, the cause lies in what it has to digest. Too much grease or too strong antiseptic solutions will reduce or prevent proper fermentation. Waste grease should therefore go into the garbage can. Also, strong doses of germ-killing solutions poured daily down sink-drains and toilets can put the hardiest septic tank out of action. The remedy for such misguided sanitary efforts is simple. Turn on all the faucets in the house and so flush the tank thoroughly. Then pour down a toilet one or two pails of warm water in which a dozen cakes of yeast have been thoroughly dissolved. The bacteria of the yeast will re-establish fermentation in the tank and all will be well if no further doses of disinfectants come along to interfere.

When one stops to consider, the septic tank is a remarkably simple and effective means of being rid of household wastes odorlessly and without contamination. Of course, such a system should be placed as far as possible from a water source and the disposal fields should not be located in a low, damp ground. The drier the soil, the better.

Incidentally, a lawn which turns brown during the dry weather of summer can frequently be kept green if watered by such a method. The lines of the disposal pipes can be laid in practically any pattern desired. Fan-shaped or with parallel laterals is a favorite one. Here the branches should be so s.p.a.ced that they are six feet apart. This will give plenty of surrounding earth to absorb the moisture.

In using this system, there are two things to bear in mind. The action that goes on within a septic tank will only dissolve paper of tissue grade. Therefore, old bandages, pieces of absorbent cotton, and the like should go into the incinerator. Otherwise, they will clog the system and a thorough cleaning will be imperative. Secondly, the leaders which care for the water from the eaves cannot be connected to it, as entirely too much water would flow into the tank during storms.

However, there are several ways of taking care of the water shed by roofs during heavy or protracted rains. In some localities where the supply of water is excessively hard or is so meager that it is not sufficient for all household purposes, pipes from the eaves are connected with an underground cistern, thus conserving the prized rain water. Otherwise, the common practice is simply to equip leaders or down-spouts with "quarter-bend" sections at the lower ends to keep water away from the foundation. This is a cheap and easy way; but if the land does not slope away from the house enough so that this water drains rapidly, pools and mud puddles are the result. Worse still, water may filter through foundation walls and leave a small lake in the cellar after every heavy rain. The disadvantages of the latter are obvious.

The remedy is a dry well for each down-spout. They are simple and inexpensive, being small pits dug six to ten feet away from foundation walls and reaching below the frost line. They are filled to a depth of about two feet with broken stone, fragments of brick, or like material and connected with the down-spouts by glazed tile pipes. A cover of roofing paper is added and the earth then replaced. The rain water is thus absorbed below ground, instead of being left to wear small gullies into an otherwise well-kept lawn.

Sometimes the contour of land about the house is such that it resembles a relief map of the Finger Lake country after each heavy rain or spring freshet. Subsurface drainage is the answer. In other words, a line of land tile like the fields of the septic tank. Through it this mislocated water may drain into a dry well, open ditch, or the gutter along the highway.

Several years ago, highway improvement presented us with such a problem. The road gang put in a culvert through which flowed the drainage from a hill on the opposite side of the road. There was no redress from the Town Fathers. Technically ours was farm land and the established custom was that highway water could wander as it would and drain as natural slope dictated. It was be flooded or do something. A subsurface drain, some fifty feet long and connected with the gutter of an intersecting road, took care of the lawn. For the rest of the water to which we were made heir by the same fit of highway betterment, two local odd-job specialists dug an open trench across a little-used field. It terminated at an old subsurface drainage line constructed years ago when some one, who had the gift, brought forth fine crops of corn, potatoes, and beans there.

There is another drainage problem that concerns mosquitoes, most exasperating of all summer pests. These insects fly but short distances. Marshy land and stagnant pools are their breeding places.

If the latter cannot be drained, oil spraying is the alternative and that is work for a professional. Again an old rubbish heap, replete with tin cans and other discards that will hold water, offers more encouragement to mosquitoes than is generally realized. Cart all such rubbish away or bury it; then you can drink your after-dinner coffee in peace on terrace or lawn, or enjoy the coolness of evening dew after a blistering hot day in the city.
