Point No.2 : Sterilising the well.
Once the well is functional and connected to the finished home plumbing system, or if you had a water test that showed the water being non-potable or out of range the whole system should be sterilised.
Let's get going....;
Note 1: Close the cold water valve supplying the hot water tank.
Note 2: Put any water softener or central filters on bypass and remove any mechaincal filter from its sump and replace the sump without the filter.
Note 3: Use household chlorine bleach in the one gallon jug. brands such a Javex and Parisienne or other equavalent at 4% concentration.
1) Remove the well cover as required.
Deep Well - Pour 1 gallon 94 litres) per 100 feet of well depth. If you do not know the depth use three gallons.
Surface Well; Pour 3 gallons of chlorine bleach into the well.
2) Run the garden hose to the well and position it 1-2 feet in the well so that it can let the water flow in a loop. When the water at the hose smell of chlorine, continue letting it spiral down the deep well or spraying the sides of the surface well for 30 minutes. Close the garden hose.
3) Surface well only: Some well may require that you use a brush tied to a long post in order to bruush down the sidewall of the surface well.
4) In the home run one cold water tap until it smell of chlorine. Close it a then repeat this for all other cold water taps including the clothes washer, toilets, showers and outside garden hose connections.
5) Let the chlorintaed water sleep in the pipes for four hours but once every hour go through all the taps and open each for about one minute to refresh the chlorinted water in that pipe section.
6) After the four hours you have to purge the well and lines of the chlorinted water. The best method is to send the garden hose into some rocks or non essential area and let it run until the water does not smell of chlorine. You can then purge the lines in the home once that is done.
7) Once the well and house pipies are sterilised and the smell of chlrine is gone, use it for at least 4-10 days before you consider talking a sample for a bacterial water test.
Take two water samples, one being a special bottle for the bacterial sampling and one regular bottle for analysing the mineral content to determine if the well water will have minerals and organics that cause water problems..
8) You need to bring in the sample within 24 hours of the sampling.
9) Don not bring in your becterial sample on Fridays after 12:00 PM.
Note : If your second analysis is still not potable, we consider that the water tableitself is transporting those contaminants on a permanant basis hence one must consider the installation of an Ultraviolet Water Sterilisation system after the pressure tank to treat the whole house water supply. A mineral analysis must first be done to determine if mineral will eventually impede the exposure of the water to the ultraviolet dossage and in some case, the UV must be preceeded by some type of water treatment system.
ATTENTION - if your prpoject is finaced by a mortgage, the bank may demand a potable water analysis as once f the conditions to accept the loan or before they pay out a progression payment schedule for the independant home builder.
Basic rules - The well and system need to be sterilised once conected to the home or after a non-potable water analysis result, Preventive well sterilisation is suggested every two years. Buying and selling well water homes requires a potable water certificate.
Well water and your home!
Point No.1 : What type of well to choose?
Point No.3 : The other accessories
The Pressure Tank
The pressure tank installat the well water entrance into the home. It should have a mimimun capacity of 20 gallons to ensure minimum strat/stop pump cycling.
Also the pressure tank has a center brass tee on which is mounted the following accessories: A - pressure gauge, B - pump pressure electrical switch, C - Garden hose drain valve, D - High pressure relief valve and E - Main water shut off valve.
The Sump Pump
We stronly recommend that you always install a sump pump basin in the floor of the basement with a sump pump that exits water through a check valve and a pipe leading outside into a surface or deep ditch independant from the house spectic lines and the house footing drains. This is a must if the septic system is a BioNest, Ecoflo or other bacterial digestion type since any water treatment system drain must be connected to the sump pump line leading outside. Do not be influenced by construction peole saying "The house is bult in an elevated area with zero chance of floodng". All well water supplied home needs to have a sump pump for all sort of reason including serivicing water treatment systems.
The drain pipes
If the well water requires treatment and the septic system is a standard type, the drain lines of such system can be connected to the house drain pipe usually in the basement. Think about that before you close off the walls hence access to such pipes.
Also, whle the house is being built thinkabotu running a 3/8" polyelthylene tubing from the mechanical room where any water treatment may be installed going under the kitchen sink. This way if the water needs to be specially filters for consumtpion, the system can eb installed in the basement and not take up precious undersink space.
Dureing the planning stage it is always preferable for both convenience and maintence that the pressure tank, the sump pump, the hot water tank, a drainage method and an electrical plug be located in the same general area. Also, space required for future water treatment is required for one or more systems depending on the water quality situation. A floor surface area of 24 sq. feet or 3' by 8' be reserved for water treatment otherwise on some cases, such equipment must be installed in areas that were originaly designated for other uses.
Keep in mind that linke other home appliences located in a mechanical room, the water treatment system will produce some noise of water flowing when they clean themselves automatically at night. Basement bedroom placement may be chosen accordingly.
Point No. 4: The water quality
The water qualit of the well you will prpduce will range form very good to very very bad. we wishto enphasize that house lans should always consider that the well water will be very bad and that house plans should take into account the worst scenario.
In simpler terms, if the house plans allow for a very small mechancial room or an area under the stairs, if the water quality demands a large treatment system configuration then the equipement will be taking up space that was not allotted for that specific usage.
But, regardless of the water problem, Filtration Technic-Eau Quebec Inc. has the systems and the know-how to solve them all. You are therefore invited to communicate with our St-Jerome office so we can look at your specific needs.
Thanks and good construction!
|So you want to build your home in the country, you chose the land based on the view and decided where to lace the home, theplans are almost done and now yu are ready to start building. So what have you actually forgotten?
All to often we here clients tell us "If we knew then that our well water was going to be so bad, we would have planned otherwise".
If your project includes the drilling of a deep well or digging of a shallow well in order to obtain your supply of potable water, you will need to consider several additional factors since you now become the happy manager and owner of your own "Independant Mini Aquaduct System". But the autonomy is not always that simple if you do not prepare for it in advance.
The well, the water inlet, the water tratement, the hot water tank, the sump pump, the water pipes and drainage pipes and the septic system and leach field are all part of a complete system that will allow you to enjoy potable and clean water in your precious new home.
We herein provide a few considerations.
Here are a few things to think about when building your home with a well.
| The Surface Well
Water sources such as rain water, snow melt, lake backrush or mountain inrush water may alone or in combination at varying degrees will saturate the land around a surface well. A surface well is basically a big hole in the ground with a cover. It is therefore more directly exposed to open air as well water waters that flow in the first layers of land, such wells are more inclined to change water quality with seasons or with major precipitation. well water will bemore proned to bacteria, iron, menganese, organic iron, tannin and turbidity as well as acid rain thathas not had the luxury of time to be neutralized by dissolving minerals.
In general a surface well will supply water that can change with the seasons, often becoming nonhygenic during sprint snow melt, summer dry spells or during autumn falling leaves
You should anticipate a space in the basement for a well pump or 1/2hp but we recommend a 3/4hp for all homes for a better pressure and flow rate both fo rthe home and for any required water treatment system. Price difference is truly minimal but the increase in flow really is a welcome addition in all cases of domestic water usage.
You will need to get accustoned to the sound of a water pump turing on and off in the basement. If you prefer, you can ask your well guy to install a submersible pump in the surface well and 1/2 hp is enough providing great pressure and flow without the noise. If you require water treatment, these are usualy much less in number when you have a submersible pump in the well.
Basic rule - if you can avoid the surface well, it is preferable to do so otherwise ask for a 3/4hp surface pump or a 1/2hp submersible in the surface well.
The Deep or Artesian Well
Deep or Artesian wells are basically a 6" or 8" diameter hole that is 100 or more feet deep (sometime up to 500 feet or more) so that the depth of the hole goes thorugh the surface waters of the surface well, passing an impermeable rock layer in order to reach the deep water table.
Water from a deep well will have the same chance of requiring one or more water treatment solutions but the water will be more stable throughout the seasons. This generally translates into a smaller system because the system does not have to be sized for the worst times of year.
In certain cases where the water coming from the deep well is extremely problematic, the main problem can sometimes be fixed by checking it for surface water infiltration and if present by physically sealing the well to prevent such infiltartions. We have seen that in some cases the water quality afterward required no treatment at all but in most cases, the final treatment required is 2 to 3 times less then the original water condition dictated.
Use a 1/2 hp submersible pump for wells up to 150' deep and a 3/4 hp for deeper wells up to 1 hp for much deeper well. Your well guywill be able to size the pump but emphasize always that you want good pressure and flow rate both for domestic usage and especially if the water requires treatment, such filtering systems may require good backwash flow rates to keep then clean.
Basic rule - A deep well is always preferred and a 3/4 hp submersible pump will provide the best pressure and flow rates.
