Charity: Water

Charity: water is a non-profit organization founded by Scott Harrison. Charity: water provided drinking water to people in developing nations.

“1 in 10 people lack access to clean water. Charity: water on a mission to change that. Here’s how.”

 

In order to have a clean water, there are different type of solutions provided.

    • Hand-Dug Wells

Skilled laborers dig up to 15 meters by hand to reach aquifers below. This is often the only relatively easy way to obtain water, particularly in developing countries that lack surface water.
It is an economical technique because it only requires physical labour with simple tools. This is the simplest method of well construction. Wells dug this way have a wider diameter which means water can be drawn from a wider zone in the water table.
These wells can capture water from less permeable materials such as fine sand, loam or clay.

    • Drilled Wells

A drilling team drills deep into the earth to reach fresh aquifers. The advantages of drilled wells are the quicker and cheaper to sink than hand-dug wells, less susceptible to contamination, no de-watering during sinking required, less lining material required compares to hand-dug wells, safer in construction and use compared to hand-dug wells and the well itself barely needs maintenance as well as many simple drilling techniques available suiting most geological conditions

    • Rainwater Catchments

Gutters on rooftops direct the flow of rainfall into a sanitary holding tank. Also called rain harvesting, these simple systems connect downspouts (gutters) to a central water tank capable of holding about 100,000 liters of water or more. Often, in dry countries, the issue is not that it never rains, but rather that when it does, most of the runoff is lost. These water systems make the best use of what little rain there is.

    • Gravity Fed Systems

The force of gravity feeds water into a community from an elevated source. The gravity fed water system is used to pull the water from springs, streams, creeks, rain barrels, and rivers upstream or uphill from the water source. You can use this system to provide water to your shower, gardens, animal barns, and even your whole house if you have it set up properly.

    • Water Purification Systems

Installed treatment systems remove contaminants from existing systems. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light. Water purification may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi as well as reduce the concentration of a range of dissolved and particulate matter.

Charity: water funded 38,113 water projects for 9.6 million people around the world.

Perak Water Board

Perak Water Board or Lembaga Air Perak (LAP) is corporate organization that started under Perak Water Board Enacment 1988. The purpose of Perak Water Board is to provide water supply services in Perak.

“To supply clean water to meet the needs of the population, both urban and rural, and the requirements of commerce and industry.”


In order to produce clean water for Perak state,few steps need to be taken

  • Raw water resource
    • At this stage, raw water from Sungai Perak which close to plants is obtained.

  • Screening
    • Raw water that obtained from earlier stage go through screening that separate physical materials such as wood, sand, grass and etc.

  • Aeration
    • Raw water is then pumped to cascade aerator. The action is perform to increase oxygen content and get rid smell and taste of the water.

Water will undergo Flocculation, Sedimentation, Filteration, Chlorination, pH adjustment, Fluoridasi, Clean Water Tank, Water Quality Monitoring before the water reach Water Distributation System to be use for citizen of Perak.

Just a Drop

Just a Drop is a charitable organization founded by a managing director of World Travel Market Flona Jerry and supported by members of international travel industry. Just a Drop support marginalised people across the world through community leading development.

“Just a Drop brings sustainable safe water, sanitation and hygiene projects to communities, transforming lives.”


In order to have safe water, there are different type of solutions provided.

  • Rainwater Harvesting
  • Rain falls and is directed into a sanitary water tank, usually by guttering. Rock catchment system operate in the same way, on a larger scale, with the rainfall that flows from a steep rock face directed and collected.

  • Water Distribution Systems
  • Work by distributing water to locations through a system of pipes. Gravity Fed Water Systems use the pull of gravity to direct the flow of water to a sanitary storage tank. Piped Water Systems work by distributing piped water to a series of taps in a community.

  • Spring Protections
  • A system is built to capture water from a naturally occurring spring source, and the clean water is stored.

  • Hand-Dug Wells
  • Wells are dug by hand, to reach the water stored in the aquifer below, at a depth of no more than 15 meters. Hand-dug wells, or shallow wells, are the most common way of extracting water in rural areas of the developing world.

Just A Drop projects have benefitted 1.5 million people in 32 countries and monitored for minimum 7 years after completions.

PureMadi

PureMadi is a nonprofit organization that collaborate with University of Virginia‘s students and faculty. PureMadi use low cost materials such as clay, water and sawdust. This technique is called as Ceramic Filter Technology.

“To prevent waterborne disease through educating, training, and empowering resource-limited communities to produce and distribute an innovative point-of-use water technology.”


In order to produce ceramic water filters, there are few steps need to be done before ceramic water filters can be used.

  • 1st Stage
    • At this stage, clay are collected from local deposit need to be dry and rocks are removed from the clay by hand. The clay is then grind into powder form for future use.

  • 2nd Stage
    • At this stage, sawdust from local sawmill needed to be sieve before using it for future use.

  • 3rd Stage
    • The processed clay and sawdust are mixed with water with particular ratio.

  • 4th Stage
    • The clay and sawdust mixture is pressed into pot shape using filter press and they needed to air-dry before moving to next step.

  • 5th Stage
    • The air-dried filters are placed in either a wood-fired or electric kiln with temperature of 870˚C. This process will allow sawdust inside clay and sawdust mixture will combust which create pore space. The filters is then cooled.

  • 6th Stage
    • The filters need to two tests to insure their quality. Filters that failed either one of the tests above have to be destroy.

  • 7th Stage
    • The filters that passed both 2 tests above are air-dried and the filters’ surfaces are painted with colloidal silver solution. They are air-dried again and packaged for distribution.

After few years, PureMadi introduced new invention called “MadiDrop” during its one-year celebration event. MadiDrop is in tablet form and is a small ceramic disk impregnated with silver or copper nanoparticles.
