  4. By using  rainwater  for toilet flushing, laundry and garden  use  alone, it can reduce mains  water requirements of a typical household by 70%. ...  Rain Harvesting  Pty Ltd manufactures a complete range of rainwater  goods and gutter mesh systems that improve  water  quality and reduce maintenance.

    Water plays a significant role in our lives since it is a precious natural resource. Over the past few years, there has been an increase of water shortages in several parts of the world. It is vital that ideal measures are put in place to help to reduce the high rate of water loss. With the change in climate patterns, people need to be aware of the alarming water shortage that we face currently and the imminent danger of severe shortage in the future. Rainwater harvesting is one of the methods that can be used for water conservation.Collecting your own rainwater is an excellent way to conserve this precious resource. A basic rainwater collection system catches rainwater from your roof or other surface and channels it into a container for storage.

    Rainwater itself is generally clean, but it can pick up microorganisms, pollutants and debris when it hits your roof. This is why systems for rainwater use inside your home often include filtration or other treatments for safety.

    Following uses

    1.  Drinking and cooking.
    2.  Bathing and laundry.
    3.  Flushing toilets.
    4. Watering lawns, gardens and houseplants.
    5. Composting.
    6.  Water for wildlife, pets or livestock
    7.  Outdoor ponds and water features
    8. Rinsing vegetables.
    9. Washing vehicles & equipment’s
    10. Fire water

     

     

  5. Dear Mayor Milton,  one of the questions that needs to be asked of the company is from which surface the rainwater is collected.  This may be from the factory roof, in which case they should install a "first flush disposal system".  This allows the first 10 minutes or so of rainfall to be disposed of - as this would contain most of the dirt (including bird droppings) to bypass their collection tank and go to drain.  After this the rainwater will enter the collection tank and be fairly clean - although a sieve should also be installed at the entrance to the collector tank to catch leaves and any other large debris.  The rainwater may still contain some fine particles and even some organic solids.  These should be filtered out with a filter as suggested by other responders, and then as a final step disinfected with UV or ozone.  The factory will need to decide whether they need to adjust the pH for the optimum product and shelf life.

  6. Dear Milton

    Basically they must to follow the process described in the Health Ministery, in Brazil we talk specifically about ANVISA to this case. In the brazilian environment permitting procedures the rain gathering system is already an obligation...so they just need to treat the water to be ok with ANVISA requisites. 

  7. Dear Mr. Nogueira da Silva.

    Basically you should request them how much water do the expect to harvest, where are they going to keep it, in which uses are they going to employ the water treatment, and which kind of treatment(s) are they going to employ with the water before using it.  And If by any chance they ask you that you should give them the regulations, you can 'put the ball in their roof' showing them that you are open to see how much do they care about the environment and which is their aim. You want to see their degree of compromise they have taking care with the environment. Once they submit you their proposal, we can analyze the parameters they provide you.

    Regards to @ll.

     

  9. Sir:

    I complement you on your actions in the matter at hand.

    Simply require the factory to pass water ,via a 4 micron filter, through a UV source as suggested elsewhere herein.

    Water storage containers can be kept at optimum levels of cleanliness by addition of our organic solution in small quantities.

    See brochure.

    Stay safe,

    Hugh.

  11. Hi,

     

    I appreciate you for enquiring before granting the permission. Rain water harvesting is a responsibility of organization and individual for reducing the ground water extraction and reduce the pumping cost and other natural resources such as coal for power generation etc. Through rain water harvesting one can fulfil its marginal water requirement

     Hence the orange bottling factory is going to use a fraction of its water requirement through rain water harvesting. I would like to brief you about the usage of water in orange bottling industry. Mentioned below:

    1. Process Application( which requires water parameters as per the applicable norms): rain water without further treatment may not fit for process application. Biological contamination in rain water is also one of the reason for preventing its direct use in process application.

    2. Equipment cleaning Application: Rain water can effectively be used directly or with pretreatment in equipment cleaning applications.

    3. Utilities such as Boiler, WTP and Cooling Tower etc.: Rain water also can be used as source of makeup for boiler, cooling tower and other water treatment plants. Rain water also can be used for fly ash scrubbing etc.

    4. Bottle washing: Harvested Rain water can be used in bottle washing.

    5. Toilet Flushing, gardening and Floor cleaning: Rain water can directly be used in toiler flushing, gardening and floor cleaning.

    6. Drinking Purposes: Harvested rain water can be used for drinking purpose after UV treatment.

     

    You can authorize rain water harvesting and impose conditions for following the regulatory norms for its usage.

     

     

  12. Rain water is the #1 preferred water source. Lakes, rivers, and springs are also ok if  inspected first.  The only negative water source is chlorinated water.  If you would take a one gallon container of bleach and drink it that would equal what you drink every year.  This also meets sustainable goals.
