charity: water believes we can end the water crisis in our lifetime.  Let's rise to the challenge...
On World Water Day (22 March 2018) IChemE’s Water Special Interest Group, launches its 2018 charity campaign.  We are again working with charity: water and aiming to provide funding for a BioSand Filter project in Cambodia:

While Cambodia has adequate quantities of water, it isn’t safe to drink. Only half of the rural population has access to a reliable source of drinking water.  Diarrhea is the second leading cause of death for children under 5 in Cambodia.
 

"The water situation in rural Cambodia deeply affects the poverty that is so prevalent in the communities we serve.” says Clear Cambodia - charity: water’s partner in Cambodia.  They selected BioSand filters as the most efficient and economical solution. BioSand technology is open source and royalty free, and the construction materials are all available locally, allowing them to build as many as finances will allow.  A home filter unit can be constructed for $60 and will provide enough clean water for a family to drink, wash, and bathe with consistently for years.
You can even see everything a BSF project needs- 

BSF
The main components of the home filter box are locally sourced concrete mix, sand and PVC pipe. They purchase all of these in the communities where the filters are constructed and used. This fuels the local economy and reduces transportation costs for the materials.  The sand and gravel that make up the filter medium are mined from two mountain quarries in Kampong Speu province outside of Phnom Penh. Sourcing the filter medium in country is better for the environment and provides jobs for the local economy.

Each family that receives a BioSand filter actively invests in the process of bringing that filter to their family, and each community actively invests in bringing the filter to their school.  Each family must invest $5 to receive a filter. They must provide the transportation to move the filter from the construction site to their home, participate in the construction and they must participate in the community education programs to ensure their filter is maintained and serves them well.  Schools must provide a roof structure to cover the filter system and a water storage tank for the latrines.

The BioSand filter medium used in the filters is so durable, it lasts for decades, requiring only regular maintenance.  To clean the filter the family will stir the surface of the BioSand medium to release the trapped particles into the standing water. This water containing 
BSF2
the particles is then removed from the filter. Then the surface of the BioSand layer is leveled and the filter is ready use again.  The home filter bodies are made of concrete and will last indefinitely. The first filters Clear Cambodia constructed are still in operation today. Our school filters tanks are made from recycled materials and have a natural life of 15 years or more.
Slow sand filters have been shown to remove almost all the disease-causing organisms found in water.

The BioSand filter has proven as effective as traditional slow sand filters, in both laboratory and field tests. The filter has been tested by various government, research, and health institutions, as well as by non-governmental organizations.  Overall, these studies have shown that the BioSand filter removes: >99.9% of protozoa and helminths, >90% of e.coli, faecal coliform and other bacteria, ~90% of viruses, ~80% of turbidity and suspended solids, 67% of iron and manganese, 50-90% of organic and inorganic toxins, but no arsenic or mercury.

The BioSand filter is made of a concrete shell on the outside with layers of sand used for water purification on the inside. The filter works through a combination of mechanical and biological processes. Water is filtered by sand particles and a biological layer that develops on the surface of the water, this layer is known as the biofilm (schmutzdecke in slow sand filtration parlance).  When water passes through the filter, the organic material it carries is trapped at the sand’s surface and forms the biological layer. Over several weeks during the filter’s initial use, micro-organisms colonize this layer and the water passing through the filter provides them with oxygen and food. These micro-organisms then remove contaminants in the water through predation. The rest of the filter structure further purifies the water through trapping, adsorption and the natural death of biological contaminants.
.
The BioSand filter can purify between 20 and 60 liters per hour and can last for decades with simple maintenance.

We need to raise £7,500 to sponsor an entire BioSand Filter project. Last year we raised £1952.60 which supported charity: water's fund for all water projects. Because charity: water’s operating costs are met by others, 100% of our donations are used to fund water projects.  Please give generously in person, and also ask if you’re company, clients or supply chain, might consider sponsoring this project.

VMG accepts donations from all over to world, donations must be entered in GBP the conversion rate will be dependent on the issuing bank.

it would be phenomenal if we can reach our target and fund a specific BioSand filter project...what a great scheme. Please give generously.

This is an excellent initiative that's been very kindly supported by Aqueum.com through their backing of the Number0 Chroma Camera via Kickstarter. I hope this goes some way towards the final target and has an excellent long term benefit.
