Non-residential Water Patterns

Published on by in Academic

I am looking for non-residential water usage daily patterns. I have curves for residential use, but I am looking for non-residential.

The AWWA does not have a curve for non-residential water usage. I assume it should be almost constant, but I need a document that would prove this.

Does anyone have suggestions where and how I can find such information?

  4. I'm aware working hours are the most important in non-residential water demand (commercial and offices). Nevertheless, it is important a back up and reference to compare, otherwise just conjection based on my opinion/experience.

    Thanks all. The paper is a good reference

  7. @ Viladmir , 

     

    Municipal water demand ls commonly classified according to the nature of the user . 
    The ordinary classifications are :
    - Domestic / Residential 
    - Public use 
    - Residential cum Commercial 
    - Commercial 
    - Industrial 
    - Loss and waste 

  8. Hi Vladimir,

    The best approach I have found is to try and group different types of non-household property based on their likely water usage patterns - achieved by understand how each type of property is using their water. So, for instance there will be a group of property types which are characterised by typically domestic-like consumption (hotels). There will be a group dominated by domestic-like consumption during office hours (offices, shopping centres etc.) and there will other more complex categories (manufacturing, industrial uses) and some with 24 hour usage.

    Of course, it depends for what purpose you are modelling - it may be as simple as saying 'residential-like profile' and applying a residential profile to some business, 'opening hours' and applying a fixed rate between e.g. 7am and 7pm, and '24 hours' and applying a fixed profile across 24 hours.

    Best wishes,

  9. if you are a expert getting a a fat salary from donations given to kenya farmers for writing articles which have no value on the ground.-5 years ago i got rainwater harvesting for our building in india & now we dont need any water tankers which is a great achievement. regarding water shortages in the agricultural field the only solution for farmers without year round irrigation is to build poly lined water ponds by rainwater harvesting of a size 100x50x5ft deep will sustain a farm of 2.5 acres for 3-4 months.

  10. The good correlation between the simulated water demand patterns and the measured patterns indicates that the basis of the design-demand-equations.The models are based on water demand patterns simulated by SIMDEUM, an end-use model to simulate residential and non-residential water demand patterns.The SIMDEUM based rules give a better prediction of the measured peak values for cold water flow than the existing guidelines and for several types of buildings. Therefore, they will lead to improved design of distribution network, of indoor plumbing and water heater capacity, resulting in more hygienic and economical installations. Due to the modular structure of SIMDEUM, it can be employed to construct all type of buildings, such as schools, sport complexes, restaurants, for which similar rules can be developed applying the presented procedure.

  11. Dear partners   hi . We are a national NGO based   in DRC Afrioca and need your supports to our WASH work in the DRC . Hope to hear from you

  12. SITE AND INDUSTRY SPECIFIC the WQA probably has the best general information by industry and volume sizes - everyone will be different.  A big factor is also highest demand period  for maximum usage is probably  much higher  and would sque  and average.

     

  13. I agree with all the previous comments but what is missing is clarity as to your requirements Vladimir, in particular where and what type of non residential use. The ranges are massive if you look at the farming or manufacturing or even power production needed for smelting.

    If you narrow it down a bit you might find more success.

    Good luck.

    1. Thanks everybody

      It is for office buildings, food courts and schools. I was looking for the pattern, not the demand in numbers. I mean, before 9 am is 0.5*Daily, from 9 to 12 is 1.3*Daily demand and so on

      Thanks for the links

  14. Vladimir water use are usually broken down into domestic, institutional, commercial and industrial. Domestic has been researched ad nauseum and the use depends on the income of the family residing on the property as well as the size of a garden if the property is alone standing. This can differ from 30 kilolitres per month to 100 for the rich. For so called cluster housing (there are different types) the different units are nowadays metered. The use there depends on the size of the garden - use ought not to exceed 30 kilolitres per month. Commercial is shops, restaurants etc. The water consumption will be according to the application from the entity as that is usually done by an engineer that will size the pipes. Institutional use (offices, schools etc) is calculated by the amount of scholars/office employees multiplied by a figure. The figure will depend on the Standards in each specific country. Industrial use depends on if it is a wet industry (bottling plant) or dry. In both cases the demand will absolutely depend on the size of the industry and the demand will be determined by the industry consultant engineer that will also apply for the connection.

     

  15. Hi Vladimir, I used to work for a company with a wide portfolio of properties and water use is very dependent on the activity being undertaken. In shopping centres, offices, schools etc. water use is most closely linked to the number of people occupying the property (footfall). Manufacturing is more closely linked to the product being manufactured, things like textile manufacture is very water intensive. Construction projects are very dependent on the type of construction (steel frame/concrete/timber etc.) and management of the commissioning of the systems before handover. I can't give you any actual data right now, I'm actually working on a project to try to collect his type of data, but I hope this helps! Ian

  17. Hello Vladimir,

    I would suggest that the reason you have residential data available is that it is fairly predictable and common across residences.

    The problem with non-residential is that range of uses.  An office building open from 9am to 5pm has a very different profile to a factory running 24 hour production. 

    Your issue will be around how you profile the non-residentials into groups that have something in common, in order to benchmark their water profiles.

    I would be very interested in any progress you make towards this as it would allow us to help customers identify losses and make savings.

    Thanks,
