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.

Well Casing Extension

Posted by Matthew Bednarz on Wed, Sep, 19, 2012 @ 15:09 PM

 

water well systems

Well Casing Extensions are a natural "next step" to take when performing a jet pump conversion or replacing a submersible well pump in a buried water well.  Buried water wells were the standard offering of well system installers until the advent of the pitless adapters in the early 60's.  All new wells must extend above grade a minimum of 6 inches.  Existing buried wells are "grandfathered in".

Homes with jet pumps (pumps that are typically located in the basement next to the well tank) can benefit from a conversion to a submersible pump.  Submersible well pumps will generate better pressure and flow.  Since they're located down the well, there's no operational noise associated with them.

Well casings that extend above grade with a water tight well cap offer several advantages over buried water wells:

  • With the well head above ground and covered by a water tight cap; there's significantly less chance of surface water intrusion into the potable water supply.
  •  The well is easier to find (critical in a "no water" emergency). 
  • The water tight cap also prevents varmint & insect intrusion.
  • Access is easier for general maintenance & inspection. 

In a well casing extension project; first thing to do is open the tile & expose the well head.

Next step is to install a casing coupling on the existing well casing so the extension can be connected to it.

Next; The new extension (piece of cast iron casing) with a pitless adapter torch cut into its' side is connected to the coupling.

After the new pump, pipe, and wire are installed; a water tight cap is installed to seal off the top of the casing.  This cap will prevent insect & varmint intrusion into the drinking water supply.  The open pit around the casing is backfilled...leaving the new extension protruding above the soil.

Take a look in your yard.  Does the well head extend above grade?  Does your well have a watertight cap? Is the cap flush with the lawn - or worse yet - partially buried?

The cap pictured below IS NOT a water tight cap:

The well cap pictured above is what we refer to as a "contractor cap".  It's nothing more than a metal baseball cap on the well casing.  A watertight cap is usually distinguishable from a contractor cap by the vertical bolts.  Contractor caps will usually only have set screws on the side to hold it in place on the casing.  While water tight caps aren't a guarantee against a bacterial problem, the very nature of their construction can significantly reduce bacterial problems in potable water supplies.
