IELTS Rainwater Diagram

IELTS Diagram Model Answer

The diagram illustrates how an Australian town collects rainwater to process in order to use as drinking water. Overall, rainwater collected from houses can be used for drinking after it has been processed by being filtered and then being treated with chemicals.

Initially, the rain which falls on the rooftop is collected by the gutter and then runs down the pipe at the side of the house into the drain at the bottom. Each house collects rainwater in this way and the rainwater is then passed along underground drains to the water filter.

The rainwater passes through the water filter to remove any impurities. Once it has been filtered, it continues along the pipes to a storage tank. From this point, the water goes from storage to the water treatment. At this stage of the process, the water is treated with chemicals in order to make it fit for consumption. When the water is ready for drinking, it travels along pipes that lead back into the houses in the town where people can use the water for daily consumption.

    Overall, diagram gives the knowledge about the process of collecting and converting rainwater to drinking water with the process of passing the water through drain pipes, water filter unit and chemical process plant.
    During rainy days, rainwater is collecting from rooftops with help of drain system which transfer the rainwater into water filter units which removes impurities after that water is store in storage tank.
    From the storage tank water send for water treatment process in water treatment unit with the help of chemicals after that water is ready for consumption. The pure water is then supply to houses through the pipes and ready to use in daily routine .

  3. The diagram demonstrates how people in Australian towns collect rainwater processes to use as drinking water.
    First of all, the rain collected by the gutter on the roof and runs through the pips down the every house. Then runs to the storage bypassing the water filters. After that water is collected to the water treatment process through the pips where the water is treated by chemicals for consumptions. In the end, water will be ready for drinking and distributed bypassing the pips to every house back.

  4. The digram illustrates the methods for collecting rainwater for the purpose of drinking by an Australian town. Overall, the rainwater collected from the houses can be used for drinking after it has been filtered and treated with chemicals.

    Firstly, the rainwater collection starts from the rooftop of the building and the runs through ta pipe at the side of the house into a drain at the bottom. Each house collects rainwater this way. The rainwater collected is passed along underground drains to be filtered.
    The rainwater passes through the water filter to remove any particles and impurities, and continues along the same path to drain into the storage, from where it goes for treatment with chemicals to make it safe for consumption. After treatment, the water goes back into the houses through the pipes, where it can be used for daily consumption.

    • Hi Liz !
      I saw your video about task 1 , but there you mentioned to write 1 para for introduction , 1 for overview and 2 for main bodies .
      But here you have only written 3 total paragraphs instead of 4 . Is it a correct way ?

      • It is fine to put the overview in the same paragraph as the introduction as long as they are two very different and clear statements. I only usually do this for diagrams if the introduction statement is very short.

  5. hello Liz,
    are there any videos on line graph description or pie chart? i am unable to find them
    any suggestions would be appreciated.

  6. Hi LIZ,
    In your first paragraph. Is it grammatically correct to insert word “it” in the sentence part “use it as drinking water” instead of ” use as drinking water”?.

  7. Hello ma’am
    Can we write i.e in our real test.
    Is it formal to write?

  8. Hi Liz,

  9. Hello Liz mam

    Dear mam, I want to clarify that is it right now that we can write overall after introduction?
    My exam is tomorrow.

  10. The diagram illustrates the process of rainwater and its distribution to the household in one city of Australia. Overall, rainwater collected from houses follow 3 main steps including filtering, storage and treatment.
    Firstly, the rainwater is collecting from rooftops houses, and flows to the pipeline beside the houses. It flows by the gravity when the water drops run into the pipe and drain. Drain should be bigger than house pipe.
    Secondly, all the collecting waters are filtered to remove unexpected materials like leaves, dust and etc. Therefore, the waters then sent into storage tank for the next steps.
    Continuously, after the storage, the water is flowed to the water treatment tank. Here, chemicals are used to make sure the water is drinking able.
    Finally, after harmless water produced, it will send to the house back again and daily it may be use for drinking. It sent through the small pipes to the houses.

    Thank you

  13. swarna pakeer says


    For this diagram, the overview and introduction are written as single paragraph. can we write the overview as separate paragraph for diagram type questions too.

  14. Hello Liz
    I read your website before taking IELTS and did well on the exam day
    I sincerely thank you

  15. hello
    it is usually passive voice is the grammer of writing a process, how it is possiple to write it by present tense? \

    • A diagram requires both passive and active voice – all present tense. That means you use the present passive voice and the active present simple.

  16. Muniza Siddiqui says

    The diagram shows collection and conversion of rain water into drinking water in an Australian town. The process involves three steps. The first step is where the rain water drains down into the common collection system below each house, which is then connected to a water filter by the help of a main pipeline. The second step involves the filteration of water. The filter has three sieves where the water is purified from large sized particles and macromolecules. The other end of the water filter is connected to a large storage tank where water is stored for a particluar amont of time. The third step is the treatment of water. The water storage tank is connected to the water treatment plant which has three ports. The first two ports are situated at the top from where the chemicals are processed to clean the water from invisible microrganisms. The final third port is connected to a long pipeline extending from the water treatment plant which delivers fresh water to each house. This water is then used for the purpose of drinking.

  17. In most of the cases in here,why you used present perfect continuous tenses except using present perfect tense

    • Why don’t you write a list of the present perfect continuous used in this model and post it in this message thread.

Then, the clear water is moved through pipes into another storage where it is treated by chemicals in order to be suitable for human consumption. Finally, the water is ready to be be drinked.

      • I don’t offer marking or feedback. However, I will say that your report must be over 150 words. Your overview must be extended. The body of the report must be divided into (usually) two paragraphs.

  18. Hi Elizabeth! “A glance at the bar graph provided reveals … ” Can i start my Task 1 like that?

    • You are not supposed to “glance” at a bar graph. You are supposed to analysis it. So, no – you shouldn’t use such expressions.

  19. Mohsin Qayyum says

    Hi liz,
    How big is the mistake if you write 25$ billions instead of of $25 billion. And it is written multiple times.

  20. Osama Hamad Jaafari says

    The diagram gives information about the various steps which an Australian town made drink water from rainwater.
    It can be clearly seen that, the rainwater has pass through a lots of machines and chemical materials before being drunk.
    the rainwater is collected from roof of house. After rainwater has been dropped to drain.

  21. Abubakar Wahlan says

    Hello, Liz
    I’m perplexed to write 3 paragraphs or 4 paragraphs for task 1 because in your process sample answer there are only 3 paragraphs where as in this pie chart sample answer there are 4 paragraphs. In addition you told in your bar graph video to write 4 paragraphs.
    So, this is just moving around my head, what to do.. Pls REPLY to me..

    • Do you think there is a set number of paragraphs? Of course, there isn’t. You are being tested on your choice of paragraphs and your choice will depend on the information presented in the graph or chart. Go back to all my model answers and make a list of all the possibilities – that doesn’t just mean the number – it means what information is put in which paragraph.

  22. Shamil sajim says

    Thank you so much Liz , it was very helpful going through these examples.

  23. Hello Liz, I wrote the introduction and overview another way.

    How about this?

    The diagram above illustrates how a town in Australia collects rainwater for the sole purpose of drinking. Overall, the rain water falls into a gutter and passes through a filtering and chemical treatment stage which is later being dispensed into various/several houses for drinking.

    I don’t know which is more appropriate “various or several”.

    • It’s a good intro and overview. You definitely can’t write “various/several” in your test – you would need to choose one only. If you are unsure, don’t use them and write “..which is later dispensed into houses for drinking”.

  24. While starting the task 1 we can use this statement…”The illustration illustrate ……..

  25. I got the exact question when I took my academic IELTS on October 20th. I just got the scores today. I scored 7.5 in writing.

    Liz, I had only followed your website for 2 weeks and scored an overall band score of 7.5. I scored less in reading (6.5) as I panicked at the end of it and had to do some guesswork.

    Being a working professional, I did most of my studying while commuting to work and in the early morning for 2 weeks.

    Thanks a lot! You are the best English Tutor!

    Amulya (from Hyderabad, India)

  26. Hi Liz,

    I am from Pakistan.
    I wanted to inform you that this question was a part of IELTs Writing Task 1 exam held on 20th October 2018 in Lahore, Pakistan.
    Thankyou so much for the information, tips and videos. I have recommended all my friends to watch your videos instead of joining an academy and save your money.

  27. I had the exact same diagram in the IELTS today! 🙂

    • Hope you did well 🙂

      • you didnt use linking words for example then,afterwards,following this to describe various stages .will it be fine to use these words to describe the different stages in this diagram? actually i have a habit of using these words in diagrams

        • Yes, you can use them whenever there is a process or diagram with clear stages which follow a set order. In the model above, the linking words are : initially, then, when, at this point. The key to a high score is using linking words flexibly which means not using them in a mechanical way and not over using them.

      • Yes! But I hadn’t seen this one on your website before I took the exam. It went very well anyway, I got the score I needed for working in the UK as an emergency physician.
        Thank you, Liz, for your accurate information and training you provide here. It’s invaluable and I wouldn’t have gotten these scores without you!

        Overall 8 – Listening 9 / Reading 8,5 / Writing 8 / Speaking 7.

  28. prafulla khadka says

    hello Liz
    thank you for your huidlines .They are really very helpful to improve our mark in ielts

  29. Hi Liz,
    I noticed that you combined your introduction and overview in one single paragraph.Why didn’t you write them as two separate paragraphs?
    Love your website,it’s really helping me out.

    • There are no actual rules about this in IELTS marking. As long as the examiner can easily locate your overview it’s fine. When the introduction is very short, I put my overview in the same paragraph.

  30. Hey Eliza!! Huge fan. LOADS OF LOVE (:

  31. hi, can we replace divorce rates with people took divorce while paraphrasing ..

  33. Kalava mahesh babu says

    Can we write the essay task1 and task2 in pointwise??because it is so easy to write by line wise not paragraph

    • I do not understand what you mean. You must write sentences – this is an English language test. You must also use paragraphs because that is a criteria for marking.

  34. I need a speaking partner for my ielts this coming august.. Please feel free to email me

  35. Hi Liz, thank you for your work here. I will have the exam next month and i’m very worried about the writing part (i’m taking the academic module). I have problems with the verb tense, I don’t know which one I should use in both task 1 and 2. Moreover, i feel very insecure regarding the cohesion and coherence aspect, i tend in fact to write in a way that might be too “twisted” to read. So, i would like to improve as fast as possibile my writing skills, also to learn how to use properly linking devices. I need to score at least 6.5 in writing part, hence i’m very nervous. Could you tell me some VERY useful book where to study in details the writing part for academic, or any other tools to achieve my goal? Thank you so much. have a nice day.

  36. hi LIZ
    This site is very helpful for me and all who are going to take the ielts test
    i wanted to know that how many questions types are in the WRITING task1 academic test and if u can ,it would be better if each question type is explained as u did for academic reading ,
    like u explained each question type and gave one example for reading ,so can do the same way for writing task 1

  37. Puspita Sari says

    Shall we write the title of the essay?

  38. Hi Liz,

    Can we put introduction and overview in same paragraph for maps and diagrams?

  39. Cesar Miranda says

    Hi Liz,

    First, I would like to thank you for your valuable work. I have a question about your example. First, in this lesson (, you explained that task 1 has 4 paragraphs, but in this example you only wrote 3 and the overall paragraph is inside the introduction, why?

    Best Regards,
    Cesar M.

    • That’s right. Most task 1 will have 4 paragraphs. Occasionally 5 – but rarely. Diagrams often have just 3 as the overview statement can be put with the introduction. At no time can you have only one body paragraph.

  40. Hi, Liz! What is the task for this diagram? Isn’t the task also written there?

    • The task will be given in full practice tests and is the same for ALL writing task 1. You must write no less than 150 words and should spend 20 mins on it. You can find full instructions in the IELTS Cambridge Test books 1 to 11.

  41. Arslan Zaidi says

    Dear Mam,

    Arslan from Pakistan. Yesterday I got my Academic module result. L:9, R:8.5, S n W: 7.5. I needed 7 each. Overall band: 8. I have come here to thank you from the core of my heart for your wonderful coaching. Your smiling ways, your comprehensive yet easily comprehensible techniques and this brilliant free of cost website which has undoubtedly helped hundreds of students so far. Please accept my sincerest gratitude. I am all prayers for you. May God bless you always.

  42. Hello there, Can you tell me if i did this correctly.
    “This diagram illustrates the process in which rainwater is gathered in a town based in Australia, in order for it to be used as drinking water. Overall, rainwater passes through different stages under every house in a process of multiple steps that changes rainwater into drinkable water

    Initially, rainwater drops over every house roof to eventually run its course into the land where drains are located. Rainwater enters through every drain which fills up the pipes running through every house. A water filter is located at the end of the passage of the filled pipe, in order for the rainwater to be filtered and stored in a big tank.

    After the rainwater is filtered and stored in the storage tank, it runs through another pipe connecting the storage tank with a tank that combines the filtered water with some treatment chemicals that cleans water and transforms it into drinking water. The water eventually runs through every house and is ready to be used through sinks as drinking water.”

    thank you in advance,

    Yusuf Kaddoura

  44. Is it possible ( water goes?) water can’t count

  45. Thanks so much Liz, wish you all the best.. 🙂

  46. Hi Liz,
    Please can you have a look at the writing task 1 I just wrote, and suggest any corrections you deem necessary. Thank you.
    The image above illustrates the process rainwater undergoes before it is suitable for drinking in a town in Australia.
    Overall, there are about 5 processes rain water goes through from the time it falls on the roof until it is treated using chemicals before it is suitable for drinking.
    First of all the rain water in collected from the roof through a drain, in the residential area. The water collected in the drain then goes through a an underground water filter , and is subsequently stored in a storage tank. The stored water then passes into a treatment unit where it is further processed using chemicals and is finally delivered through faucets into homes for drinking.

  47. Hi Liza
    How can I download the lessons?

  48. Hello Liz, I know for a fact that you cannot write any opinions in the writing task 1 but I checked a website and saw the person stated their opinion. Can u please check this sample because it got me confused. Thank you! (Academic writing task 1 #9)

  49. Mohan Angbo says

    Dear Madam Liz,
    Thank you for your guidance. It was like simple in seeing but more difficult in doing. I could not got it right even on an average while comparing with the model answer you have posted.
    I have always confusion about using the word “Being”. I used to ask my teachers while studying in colleges but they never satisfied. Some said it is the word describing something in process however I did not perceive it clearly. In this post, too, you have used it as “After being treated and after being filtered”. I do not understand that means the process of filtering is already finished or is being just finished or it does mean that is in the past sense or work-in-progress sense ?

    Anyway, I find it very difficult type question.

    with regards,

  50. Hi mam

  54. Tochy Abraham says

    The diagram illustrates how Australian collects rainwater for consumption after some processes. The step by step method as seen in the diagram has been used and still on, in the Australia to generate drinking water during the rainy season.
    From the illustrated diagram it can seen that the rainwater after coming down from the roof of the house, it’s been channelled through the pipe beside the building directly for filtration to eliminate clumps and other particles, to be stored in on a large container.
    The stored rainwater that has undergone filterstion processes will further be treated with a chemical may be Chlorine to keep it safe from germs and other micro organism that might be present. After then, the Chlorinated rainwater is been distributed to Australians for drinking and for daily consumption.

  55. Tochy Abraham says

    Really, the answers on this task 2 writing are brief and concise. Am just thinking, if there’s a way you can give us the skeleton to answer questions like that. Like a step order. Thanks

    • I hope to make a complete collection of writing task 1 lessons next year for my online course. But unfortunately, I won’t have time this year.
      All the best

  56. That is a superb answer for the task. You are surely an expert in IELTS.

  57. Wilson kiyingi says

    Thank you so much Liz, I am just preparing for the ielts test. I discovered your website just recently and I am finding it so helpful. I will need some help with the writing task 2 lessons and I am ready to pay.


  58. Hi liz, i hope you can spare some of your time to read my own version of the above diagram. Thank you.

    The diagram gives information about the process of converting rainwater to potable water in Australian Town. Overall, the rainwater collected is store and cure in a huge chambers located underground, as well as the drain and the line pipe that connects to several houses.

    The rainwater that falls from the houses in Australian town is being catch by a drain and pass through a water filter that disposes large particles present in rainwater. Then, it is stored in a huge chamber underground before it is transfer to another chamber for treatment.

    In terms of treating rainwater, a chemical mixtures are added into the rainwater to cure micro organisms that are harmful or can cause certain diseases to the residents. After the water is cured, it passes again through another pipe for distribution of potable water to the different houses. Consequently, residents will use and drink this cured potable rain water.

    ***thank you liz:)

    • The diagram clearly illustrates the chain of events about how an Australian town collects rainwater to be utilized as drinking water.

      Initially, as rainwater falls on the rooftop of houses it will be collected by each of their respective underground drains through a waterpipe that can be found on the side of these houses. From each of these drains, it will be delivered to an underground water filter to remove particles and impurities from it. Next to the filtering process, it will then proceed to the water storage. Once the storage is filled, at this point, the water is now being led to a water treatment area where a chemical or two is used for it to finally become a drinking water. After undergoing such treatment, it is now ready to be distributed for all households to consume by coursing through pipes, to complete the process.

      Overall, rainwater can be converted to a drinking water by the following process in sequence such as collection, filtration, and chemical treatment.

  59. I’m just wondering is there a way to print things off this site?

    • No. However, some of the reading passages and vocabulary pages have pdf downloads.
      All the best

    • I can say, in the firefox browser you have a chance to copy material by pushing “view” on the top and choosing “enter reader view” .

      • To be honest, the thought of having my work copied is depressing and makes me think of quitting and not providing more lessons for free. It’s too shocking to think of working for one year for no salary could result in having all my work stolen.
