Rain Water Purification and Storage

Abstract

Rainwater harvesting is one of the efficient ways of utilizing rain water for household purposes. Many of the underdeveloped and developing nations in Africa and South Asia rely majorly on these harvests since many years. While many of the rain water harvesting systems are designed for non-potable purposes, the water can be purified by use of local resources like charcoal, ceramic/clay pots and cotton sleeves. These simple water purification materials are scientifically proven to provide safe drinking water. Now all it needs is a simple, robust and affordable filter unit that can serve this purpose. Our OSAT project aims to provide such water purification technique in most affordable way.

Bill of Materials

  1. Link to all source files using open source CAD
  2. 1.75mm PLA 3D Printer Filament (2kg), $15 USD
  3. charcoal (1 kg max), $2 USD, free of cost at local site
  4. ceramic/clay pieces, free of cost at local site
  5. cotton sleeve, $0.2 USD, mostly free of cost at local site

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. PLA and PETG Filament

Skills and Knowledge Necessary to Make the OSAT

  • If you used special skill – link to relevant Wikipedia or Wikiversity articles/courses

Patience

Technical Specifications and Assembly Instructions

  1. Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
  2. Include print time estimate
  3. Include assembly time estimate
  4. Including drawings or pictures of the device at stage of assembly at minimum. (Upload)
  5. Consider video if appropriate

Common Problems and Solutions

  • Include common mistakes/problems to avoid in building your OSAT and how to overcome them

'Ultimaker Cura;' 3D printing software was used to print all the parts. Following are the print details:

FUNNEL LOWER BODY Nozzle: 0.8mm Material: PLA Profile: Fast

Approximate time to print: 3hrs 30 mins Approximate spool length required: 6.5 meter Approximate spool weight: 51 grams

FUNNEL UPPER BODY Nozzle: 0.8mm Material: PLA Profile: Fast

Approximate time to print: 8hrs Approximate spool length required: 14.45 meter Approximate spool weight: 114 grams

POT Nozzle: 0.8mm Material: PLA Profile: Fast

Approximate time to print: 12hrs Approximate spool length required: 18 meter Approximate spool weight: 130 grams

PIN Nozzle: 0.8mm Material: PLA Profile: Fast

Approximate time to print: 10min Approximate spool length required: 5 meter Approximate spool weight: 20 grams

ASSEMBLY TIME ESTIMATE: 5 mins

Cost savings

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs
  2. Find a commercial equivalent, cite it and put the [url in square brackets]
  3. Calculate $ savings and % savings

My cost $20 commercial cost-$180 $ saving-160 % savings-85%

Benefited Internet Communities

  • Name and add links to at least 5 using single brackets around [url name]

References

  • The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did.

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
