Unless you've been away from CT on vacation for a very long time, you're probably aware of the drought conditions we are facing here in CT.  Drive by a local reservoir, river or stream and you'll readily see signs that we're definitely experiencing a deficit in rain fall.

 What oftentimes gets overlooked is the affect climatic conditions have on  our private water well systems...particularly rainfall deficits.  While up to  97% of the world's fresh water supply is sub surface, this doesn't mean that  well pumps are drawing from an infinite source.  Wells are drilled down until  there are signs of enough water filling the bore hole.  If the "yield" (flow of  water into the well) is poor, the driller keeps drilling down until a marked  improvement is noted.  The downside to consider is; the deeper you go -  the bigger the equipment needed to deliver the water up into the home to  point of use.  Bigger = more $$$.

 

 

 

Drought_pic_tied_faucet.jpg We're currently getting more and more calls  from home owners with wells regarding  problems with water quality, treatment  system issues, and even problems with  appliances that utilize water.  The sad reality  is; aside from conserving water as best you  can, there's not much you can do about the availability of water in the ground for use. 

With respect to water conservation, things like doing full loads of laundry, running the dishwasher with a full load of dishware, shortening shower times...and cutting back or altogether eliminating irrigation are the hallmarks of water conservation for the private water well owner.  

The first tell tale signs of a water supply issue are typically the loss of water pressure or simply no water at the taps.  This oftentimes occurs first thing in the morning when the active modern day family is getting ready for the day's activities. In many cases, the well recovers by evening when everyone returns home, which encourages the homeowner to shrug it off as an "anomaly" or something else.  Repeated incidences of running out of water or pressure drops that start to happen more frequently indicate an acute problem turning chronic.

What's a home owner to do with a private water well during drought conditions?  Aside from the aforementioned water conservation measures, there are things that can be done to improve water supply issues. 

In - ground options:

Hydrofracking: This is a process where high pressure water is pumped into the well head.  The goal is for the pressure to open up & clear out the cracks in the bedrock into which the well is drilled.  The hope here is that these newly formed fissures and newly cleaned out existing ones will yield more water supplied to the well.  While this can be a successful process, there are no guaranties of any level of success.

Drill a new well: Drilling a new well is the most expensive option which also carries no guarantee of success unless you have a bottomless wallet.  In that case, the driller just keeps drilling until an adequate supply is tapped.  Aside from the cost of "drilling to China"; there is now that added expense of installing a pumping system robust enough to deliver the water to the surface...not to mention increased operational expense of bigger motors etc.Well_drilling_rig.jpg

In - house options:

PumpTec.jpg A "pump tec" can be installed to  monitor pump operation and  temporarily shut down the well  pump if a lack of water is detected.   While this doesn't solve the water  supply issue, the pump tec will at  least help protect the well pump  from burning out.  Most any well  system can benefit from the protection of a pump tec device.  Newer sub drive pump systems have a pump tec type feature built into the control panel.  The pump tec can be installed most often for a few hundred dollars, making it the most cost effective step to implement in dealing with wells affected by drought conditions.

 

Ganged_up_pressure_tanks.jpg Multiple pressure tanks:  Ganging up multiple  pressure tanks together will increase storage  capacity...marginally. A common misconception  regarding pressure tanks is that they fill up completely  with water.  The reality; pressure tanks - when full - are  only filled roughly one third the total volume of the tank.    As an example; the largest standard residential pressure  tank (WX 350 - 26" x 61" tall with a total volume of 119  gallons) holds 35 gallons when operating at a 40/60 psi  pressure cycle.  Ganging up pressure tanks should be  viewed as a strategy for increasing pump cycle time - not  to appreciably increase storage capacity.

 

 

 

 

 

Static_Tank_in_crawl_space-1.jpgStatic Storage:  Storing water at atmospheric pressure in large volumes is probably the most reliable / cost effective approach to dealing with water production issues from your well.  Water is pumped from the well, into tank(s) located in the basement.  When water is called for use, a pump sends water to that usage point.  If the well is stressed and can't produce a lot of water at once, the water can be added gradually to the static storage.  Once a reservoir has been developed, the well will have more time to "recover" because the water used in the home will be coming from the static system...not directly out of the ground.  This too doesn't solve the lack of available sub surface water, but it does make the situation more manageable at a fraction of the cost of some other options.

Pressure Tanks

WATER WELL SYSTEMS

                             PRESSURE TANKS, WELL TANKS, STORAGE TANKS

Pressure tanks, holding tanks, storage tanks, well tanks, water tanks etc. etc. etc.  There are many different names that well system pressure tanks are recognized by.  None of the nomenclature is wrong...but the reality is; pressure tanks are the "pressure regulators" of private water well systems.

Pressure tanks don't hold large volumes of water.  The largest residential bladder style pressure tank holds approximately 36 gallons when completely full.  Unfortunately, 36 gallons doesn't go very far when you're out of power for a week!  This unfortunate reality has recently been acknowledged by many a well owner after hurricane Sandy came to visit. 

The primary function of a well or pressure tank is to keep submersible pump cycling to a minimum.  Submersible well pumps heat up as a result of the starting torque of the motor.  The water that the pump - pumps; is also the water that cools the pump.  Therefore; once started - a submersible well pump should run for at least a minute to allow for adequate cooling.  Pumps over 1 hp require even longer pump cycles.   If a pressure tank is too small or has "failed"...the frequent starting and stopping of the pump will soon cause pump failure. 

how a well tank works

Before the advent of the bladder type tanks with captive air cells; hydropnuematic tanks were the standard offering in the private water well marketplace.  Some homes are still serviced with this type of tank.  An easily distinguishable characteristic of the galvanized well tank is the bare "page fence" metal finish on the outside of the tank.  The undesirable aspects of this tank are many. 

Galvanized well tank     bladder tank

Galvanized tanks offer no physical separation of air and water within the tank.  This can lead to the oxidation of dissolved metals in the water which can increase staining, cause colorization of the water, and promote bad tastes.  The oxidized metals will also create a layer of sludge at the bottom of the tank which eventually can lead to pressure switch issues and reduced tank performance efficiency.  Sometimes; it is not possible to simply remove a galvanized tank and replace it with a bladder tank.  The good news is that there are now fiberglas tanks designed to retrofit installs that originally included galvanized tanks.  These tanks do still allow for air and water contact - but the corrosion and leaching concerns are eliminated.

 pressure tank retention tank

Pressure tanks should be "balanced" periodically to ensure the proper amount of pressurized air is in the tank which will optimize the pump cycle.  A ruptured bladder is the silent killer of well pumps.  A simple check any homeowner can do is tap on the tank.  The bottom of the tank should sound solid.  The top half to two thirds should sound hollow.  If the pressure tank sounds solid at the top...the bladder may be ruptured...or it may need to be serviced.  This should be done ASAP because a ruptured bladder will lead to pump failure!
