The diagram below shows a simple system that turn dirty water into clean water.

Summarise the information by selecting and reporting the main features, and make comparisions where relevant.

A glance at the given diagram depicts the process of transforming filthy water into drinkable water via a simple filtration system.

There are 5 main stages, commencing in lifting the lid of plastic barrel and pouring dirty water into it. The water passes through 3 filters and traveled up into a pipe placed at the top of the drum, and culminating in storing fresh water in a tank, ready for use.

In the initial stage, the preparation of a plastic barrel and three storage drums is arranged adjacent to each other. Every drum is filled up with 3 substances including sand, charcoal an gravel respectively. After that, a pipeline is installed at the last layer and follows the barrel to the storage drum, where drinking water is stored.

The production of clean water will happen in the following steps: untreated water is absorbed slowly through 3 layers in other to eliminate metal compounds, odors and dirty. Then this water is delivered via a tube to the storage container equipped a water tap. Consequently, when the tap is opened, potable water is released available.

Errors and Improvements:

1. "A glance at the given diagram depicts" -> "An examination of the provided diagram illustrates"
   Explanation: Replacing "A glance at the given diagram depicts" with "An examination of the provided diagram illustrates" elevates the formality of the language and emphasizes a more thorough review of the diagram.

2. "commencing in lifting the lid of plastic barrel" -> "initiating by lifting the lid of the plastic barrel"
   Explanation: Substituting "commencing in lifting" with "initiating by lifting" maintains the meaning while using a more precise and formal expression.

3. "traveled up into a pipe" -> "travels up through a pipe"
   Explanation: Changing "traveled up into a pipe" to "travels up through a pipe" improves the consistency of verb tense and enhances clarity by specifying the direction of water movement.

4. "culminating in storing fresh water in a tank" -> "resulting in the storage of fresh water in a tank"
   Explanation: Replacing "culminating in storing" with "resulting in the storage of" offers a more refined and precise expression, emphasizing the outcome of the process.

5. "The preparation of a plastic barrel and three storage drums is arranged adjacent to each other." -> "The arrangement involves preparing a plastic barrel and three storage drums placed adjacent to each other."
   Explanation: Transforming "The preparation of a plastic barrel and three storage drums is arranged adjacent to each other" to "The arrangement involves preparing a plastic barrel and three storage drums placed adjacent to each other" enhances clarity and provides a more structured description.

6. "Every drum is filled up with 3 substances including sand, charcoal an gravel respectively." -> "Each drum is filled with three substances: sand, charcoal, and gravel, respectively."
   Explanation: Replacing "Every drum is filled up with 3 substances including" with "Each drum is filled with three substances: sand, charcoal, and gravel, respectively" offers a more concise and grammatically accurate expression.

7. "After that, a pipeline is installed at the last layer and follows the barrel to the storage drum, where drinking water is stored." -> "Subsequently, a pipeline is installed at the final layer, extending from the barrel to the storage drum where drinking water is stored."
   Explanation: Modifying "After that, a pipeline is installed at the last layer and follows the barrel to the storage drum, where drinking water is stored" to "Subsequently, a pipeline is installed at the final layer, extending from the barrel to the storage drum where drinking water is stored" enhances the flow of the sentence and provides a more detailed description.

8. "The production of clean water will happen" -> "The generation of clean water occurs"
   Explanation: Changing "The production of clean water will happen" to "The generation of clean water occurs" maintains a more active and concise expression.

9. "absorbed slowly through 3 layers in other to eliminate metal compounds" -> "slowly absorbed through three layers to eliminate metal compounds"
   Explanation: Replacing "absorbed slowly through 3 layers in other to eliminate" with "slowly absorbed through three layers to eliminate" corrects the grammatical structure and improves clarity.

10. "Consequently, when the tap is opened, potable water is released available." -> "As a result, opening the tap releases potable water."
    Explanation: Modifying "Consequently, when the tap is opened, potable water is released available" to "As a result, opening the tap releases potable water" provides a more concise and grammatically correct expression.

The provided diagram illustrates a straightforward process of purifying contaminated water to make it suitable for consumption, utilizing a basic filtration system.

The procedure comprises five primary stages. Initially, the lid of a plastic barrel is raised, and unclean water is poured into it. Subsequently, the water undergoes filtration through three distinct layers and ascends through a pipe positioned atop the drum. The process concludes with the storage of purified water in a tank, ready for use.

To initiate the sequence, three storage drums and a plastic barrel are arranged in close proximity. Each drum is filled with three substances: sand, charcoal, and gravel. A pipeline is then integrated into the final layer, extending from the barrel to the storage drum, where the potable water is retained.

The purification of the water unfolds through a series of steps. Initially, untreated water permeates slowly through three layers, effectively eliminating metal compounds, odors, and impurities. Subsequently, the purified water is conveyed through a tube to the storage container, which is equipped with a water tap. Consequently, upon opening the tap, potable water is made available for consumption.

This enhanced rendition maintains the original data points while refining grammar, sentence structure, and vocabulary usage to meet the standards expected in the IELTS Task 1 assessment.
