TIPS FOR MAINTAINING YOUR WELL   

Well Head Picture

The safety and purity of your drinking water and the efficient operation of your private well system depends on a well-organized maintenance program. Protect your investment in a quality water supply through regular inspection, testing and repair or treatment.

Gather a comprehensive history on your well and water quality. If you don't already have a well log (also known as a water well record or drilling report), check  the BC Governments Well Water Application Site or  ask your well driller, or call us,  for a copy if available.  The well log will provide you with information on the age, depth and static water level of the well.  
 
Set a Well Maintenance Schedule 
Plan for the maintenance of the wellhead, well system, water quality, water treatment devices and septic system.

Well Inspection
*Inspect your wellhead several times a year. Check the condition of the well covering, casing and well cap to make sure all are in good repair, leaving no cracks or other entry points for potential pollutants.

* Have the well system, including the pump, storage tank, pipes and valves, and water flow, inspected every 10 years by a qualified well driller or pump installer.

*If you have no inspection record and cannot determine the age of the well, have it inspected immediately by a water well professional. A water well professional can also help you to determine if the well can be reconditioned to make it more productive

*When your well reaches the end of its serviceable life, usually more than 20 years, contact your water well professional to install a new system and properly close the old well.

Water Softener
How do Water Softeners Work?

The three main components of water softeners, are a mineral tank, a brine tank and a control valve. Water softeners generally contain some plastic beads, which are also known as resin . These beads or resin contain sodium ions, which they exchange with the calcium and magnesium ions when water passes through them. These plastic beads or resin are located in the mineral tank, which is the main site for removing the hardness of water. The resin is actually negatively charged, while the calcium and magnesium ions are positively charged. So the negatively charged resin easily attracts the positively charged ions and soften the hard water. But over a period of time, these beads are required to be regenerated, when the sodium ions are completely exhausted and replaced by the calcium and magnesium ions. Regeneration is a simple procedure, where the beads are s
oaked in sodium ions.

The second component of a water softener is a brine tank and it contains brine, which is nothing but highly concentrated saline water. This brine solution contains sodium and it is pumped into the mineral tank, when the resin requires regeneration. So, regeneration phase involves the pumping of the brine solution containing sodium ions into the mineral tank, which helps to replace the accumulated calcium and magnesium ions. The water with excess calcium and magnesium is then flushed out of the tank.

The third component of the softener is the valve, today the control valves area computerized.  Water is metered and the valve determines the timing of regeneration. When the resin or plastic beads exhaust the sodium ions completely, the control valve reverses the flow of water, to drain out the accumulated debris. It pumps the brine solution to regenerate the plastic beads, by coating them with salt or sodium, so that the process of water softening can be resumed once again. These metered valves can be very cost saving by using less salt to regenerate the media.
It is important to service the valve and the brine tank on a yearly basis to ensure that the softener  back washes properly and the media tank does not get plugged with the calcium and magnesium ions. This regular maintenance will enable the softening media to have a long life.

"Why does my water turn cloudy sometimes?"   

Bacteria are invisible to the naked eye however they can build up to the point where people will notice a sudden cloudiness to their water. This is the biofilm sloughling off the plumbing. The best thing is to have the water tested periodically for the presence of bacteria.People get hung up on the number of bacteria in their water, one time is low, like 10 cfu's (colony forming units) and then they "shock" the well and retest the water after a couple of weeks and find the count 300 cfu's. This is very common. To me, it is either present or not.

Let me explain what is happening. When you chlorinate (shock) a well with sodium or calcium hypochloride (liquid or granular bleach) it dissolves in water and forms hypochlorous acid and a hypochorite ion. We use the ion to oxidize metals like iron and manganese to turn them into a solid and filter them out of the water. We use the hypochlorous acid to destroy the bacteria in the water. The
pH of the water will determine if we have a predominance of the ion or the acid, so the
lower the pH of the water, the more acid we have to take care of the bacteria. That why it is very important to make sure the water that we are adding the chlorine to is below a pH of 7.0. We usually have to lower the well water pH by adding an acid such as citric acid, acetic acid (vinegar) or something stronger. Once we get it to the correct level of between 5.5 and 6.5, we add the CORRECT amount of chlorine. I say CORRECT amount of chlorine because household bleach is 5.25% chlorine. The other 94.75% is buffers and fillers which RAISE the pH of the water and therefore neutralize the ability of the hypochlorous acid to kill the bacteria! So in order to have the best shot at eradicating the bacteria in your well, the water has to be on the acidic side and have a concentration of between 50-200 ppm. It is usually left in this state for up to 24 hours before it is flushed out. Which brings me back to my original point. If the well owner shocked his well once and had little effect on the bacteria, they usually would add a bunch of chlorine the second time thinking that will surely get rid of the bacteria. WRONG.

Did you know?

   

In 1804 the first actual municipal water treatment plant designed by Robert Thom, was built in Scotland. The water treatment was based on slow sand filtration, and horse and cart distributed the water. Three years later the pipes were installed.
