The Solar Lampurifier

Published on August 1, 2016 um 13:57

Explain your idea in details:

My group and I have come up with an idea which helps to use a source of water which people rarely use, rainwater. Rainwater comes in large quantities every time there is a down pour. This water is never used due to its un-hygienic properties. The product which we have designed will make use of this water by filtering and storing it for people to drink. Our lamp post is designed with its own power source by using the solar panel which is mounted high up. The solar panel is used to charge the onboard battery power supply, which will then be used to power up lights and two sensors which detect light intensity and presence of water. The moisture sensor enables two barriers to come out, which helps to direct water into a hole connecting to the water filtration system and then onto the containment tank. From the containment tank, a faucet will be placed outside so as to let people fill up their water bottles. The product can be placed at the sides of pathways. It also provides shade for people to escape the hot sunlight. A key feature we have implemented into our design is the interchangeable water filter. This filter is designed to function like cartridges making it easy to be replaced. We intend to make this product a type of solution to the water crisis the third world countries face today. By placing our product along pathways, it can provide lighting for people during the night time and provides clean, filtered and drinkable water to people which do not have easy access to a source of clean water.

Expected impact of your idea on sustainable development

In many parts of the world, clean and drinkable water is not easily obtainable. 884 million people in the world lack access to safe water supplies. More than 840,000 people die each year from water-related disease. Women and girls especially bear the burden of walking miles at a time to gather water from streams and ponds - full of water-borne disease that is making them and their families sick. This is just one of the many problems these people face in their daily lives. The main reason that our product is needed in the majority of the third world countries is because having clean water to drink is the basic essential everyone should and must have. By having this product in these countries, this helps to make their life a lot better. In turn, lesser diseases will spread which prolongs their lives as well. This not only helps the countries internationally, but globally as well. Diseases such as Guinea Worm Disease, Typhoid and Dysentery can be prevented.

Plans for implementation and sustainability

Firstly, we created a 3D model design of the idea.  We worked hard on different designs and came up with one that best suited the goal we intend to achieve. We then got an approval from our supervisor and moved on to create a prototype model made out of cardboard.

Secondly, we wanted to keep our production cost low and managed to keep it below $300. We are very fortunate that our school has given us a budget of $3000 to buy materials. We made sure to materials that are in high abundance  so that if parts of our product were to fail, replacing them would be very easy and cost effective.

Lastly, we want to promote our idea by presenting our product on the website, 'Kickstarter' with the hopes of creating a startup company in the future. We hope people can see and understand the goal we want to achieve.


Your profile

We are a team of 19 year old students from Temasek Polytechnic of Singapore. Our names are; Abdel Baary, Irving Tan and Ahmed Atheeq. We are currently pursuing a diploma in Mechatronics and have focused on the creation of a product that can facilitate sustainability. In our research we have found a large population of people who still lack access to clean water. Our team is driven by the desire to find innovative ways in finding solutions to problems in third world countries. As a result, we came up with the idea of the, Water Filter Lamp Post. We have presented our idea to the diploma head of our school and received positive feedback. We're passionate about solving the water crisis in third world countries, and made use of our Final Year Project budget to create a product in hopes of having a more equal sustainable environment across the world.

We need to collect any droplet of water whether you stay near by river or arid land. Clean water these days are very precious to beings. The idea of project suits for everywhere. I like the idea of this project such a simple and nobel. I voted for this project.

Great idea indeed

@Yusuf Thank you for your comment. We have to angle the solar panel for it to get the most amount of sun light. This means that we will have to sacrifice some shade area.

August 2, 2016 03:38

@Lok Thank you for your suggestion. We use ultraviolet light in one of the filtering system, which targets microscopic organisms like algae, parasites and bacteria, shortening the life cycle of the organism. Yes! A plastic window is a great idea. We will look into it!

@Pua Siew Lin Thank you for your comment. We designed this product with the aim of putting the water filter lamp post in third world countries such as Haiti and Afghanistan, countries with high levels or rainwater.

You guys should add abit more shade around the solar panel


August 2, 2016 01:23

This is indeed a great idea! Good thinking! There may be a need to prevent contamination of water in the storage tank eg algae growth. Also good to have a plastic window to indicate water level in storage tank visually.

yes I think that this is a good idea. it can help people who is lack of water and needed water for survival. but instead, I suggest that this lamp could also be at different countries such as Africa as they do not have access to clean water and this could help in the improvement of their lives :")
