an explanation of how my filters work
ive had lots of questions about these, so i decided to address them today.
Q: how much did they cost you?
A:$250, minus media.
Q:were they hard to build?
A:no, not at all. took a little less than 2hrs start to finish.
Q:do they work well?
A:i studied the design for almost 6 months before building, so i hope so. its a combination of a few systems and designs ive seen over the years. simple, and effective.
heres the parts needed to replicate this system.
4-55 gallon barrels, doesnt matter about which top it has.
2-1″ bulkheads(for inlets)
6-1″ male adapters
2-1″ female adapters
2-1″ ball valves
3-2″/5′ long pvc pipe pieces
2-2″ elbows
8-hose clamps
1-100′ roll of 1″ pipe
1-tube of 100% silicone sealant.
and thats it, cost me 100 for the barrels, and 150 for fittings and pipe
if you want to build this, message me and ill send ya the entire build instructions for these.

This is my new DIY fibreglass backround.How the BioSand Water Filter works – Samaritan’s Purse CANADA
The BioSand Water Filter is an adaptation of slow-sand filtration that is designed for use by families at the household level. This award-winning water filtration technology was developed by Dr. David Manz, a former University of Calgary professor.
The filters are a proven, effective, and inexpensive technology. From start to finish the filters can be constructed in roughly 10 days, at an average cost of $100, which covers the raw materials, construction, transportation, supervision, training for the family in filter maintenance and personal hygiene, as well as monitoring and evaluation.
The filter removes organisms responsible for diseases spread by water, such as cholera, typhoid fever, and amoebic dysentery. The filter also strains out particles causing cloudiness, and much of the organic matter responsible for taste, colour, and odour.
One of the UN Millennium Development Goals is to reduce, by half, the proportion of people without access to safe drinking water and hygienic sanitation by the year 2015. Samaritans Purse is helping make this possible. Already more than 70,000 BioSand Water filters have been installed, bringing safe water to an estimated 560,000 individuals worldwide.
The Filtration Process
The filter is very durable, constructed from concrete, sand, gravel, and PVC piping. These materials can be found in almost every country and enable community members to help construct the filters on location.
Water is poured into the top of the filter and flows down through sand. Water that requires filtration usually contains various types of organic matter, sediment, and living organisms. The water first passes through the diffuser plate, which reduces the disruptive force of the input water and large debris, and protects a delicate biological layer. The filter sand functions as a physical barrier that traps particles and larger organisms, causing them to accumulate in the uppermost layers of the filter. Organic material and organisms caught in the sand eventually develop into a dense population referred to as the biological layer, or schmutzdecke.
As the water passes through the biological layer, microbial contaminants such as parasites, bacteria, viruses, and organic contaminants are consumed by the organisms. The filter is designed to hold water above the top of the sand to sustain the biological layer while the filter water is not in use. This provides the constant aquatic environment that is necessary for the organisms present in the biological layer to survive.
The fine sand acts as a microscopic sedimentation bed as the water passes through the filter, helping remove cloudiness, odour, taste, and harmful micro-organisms from the water. The size and shape of the sand grains are critical to the formation of the biological layer and therefore the effectiveness of the filter. Sand is specifically selected and prepared to achieve proper filtration. By the time the water reaches the layers of coarse sand and gravel at the bottom of the filter, 95 to 99.0 per cent of microbial contaminants have been eliminated by the BioSand Water Filter.1
The filtered water flows out of the spout and is collected in a safe storage container to prevent post-treatment contamination. The average flow rate of the filter is one litre per minute, which allows for 60 litres to be filtered per hour, enough to provide a family of eight with sufficient water for their daily drinking, cooking, cleaning, and hygiene needs. An individual requires a minimum of 7.5 15 litres of water per day for basic needs2, which is well within the capabilities of the BioSand Water Filter.
Maintenance
As the filter is used, the biological layer matures and thickens, causing the flow of water through the filter to slow. Recipients of filters are trained to watch for decreased flow and can renew the filter simply by skimming off any debris from the top of the sand, and by gently stirring the sand to break-up the biological layer. The quality of source water will determine how often this process is necessary.

Home Made Water Filter
I have used this simple water filter for the past eight years in Brazil. It cost about $3 to make. This filter MUST be used with some chemical means of purification or boiling to make the water safe.

Innovate or Die – Aquaduct: Mobile Filtration Vehicle
The Aquaduct is pedal powered vehicle that transports, filters, and stores water for the developing world. A peristaltic pump attached to the pedal crank draws water from a large tank, through a filter, to a smaller clean tank. The clean tank is removable and closed for contamination-free home storage and use. A clutch engages and disengages the drive belt from the pedal crank, enabling the rider to filter the water while traveling or while stationary.
The Aquaduct is the winning entry in the Innovate or Die contest put on by Google and Specialized. The contest challenge was to build a pedal powered machine that has environmental impact. Please visit our blog ( http://theaquaduct.blogspot.com/ ) or email team.aquaduct@gmail.com for more details.
