 Philosophy:  We are missionaries.  Most of our customers are missionaries.  We understand how hard it is to get things done in the third world.  We also understand what it means to work with limited resources.  That is why we have adopted a philosophy of "de-engineering" and sharing of information here at Hydromissions.  We do not patent or copyright any of our products - that would defeat our purpose.  You should be able to look at any of our products and say, "I could make that."  Go for it.  However, we believe that you will find that we make the products better and less expensive than most people could at home.

Our products are unique because they are designed to be reproduced or repaired in whatever country you serve.  There are no complicated engines or costly parts to break down, and the local people can easily learn to use and maintain the equipment themselves.  In addition, our products are designed to be extremely portable, allowing you to expand your water ministry into new areas that would be difficult to reach by other methods.  (top)

We are making purchasing Hydromissions tools even easier by partnering with EDGE Outreach in Louisville, Kentucky.  EDGE is great group of folks that can help you with your questions and get you the tools you need. Give them a call!

Pumps & Water Lifting

The Hydromissions BB-01 "Bailer Bucket" is about as low-tech as you can get.  It is basically the classic idea of lowering a bucket down a well, but modernized for smaller diameter (4 inch/100mm) tube wells.  We sell the BB-01 as a simple kit that packs into an ultra-small (4 inch x 4 inch x 6 inch) box, weighing a mere 21 ounces.  The real beauty of it is that, once in the field, all you need to buy is a short (3 ft/1 meter) piece of 3 inch diameter PVC and a rope.  And if you want to get fancy with a crank and pulley system (windlass), we have designed an excellent one using any junker bicycle that you happen find lying around (see detailed instructions in the "Free Plans" section).  This system can make a MAJOR difference in remote villages due to its simplicity, extremely low cost, and local sustainability.  In addition, the BB-01 "Bailer Bucket" allows you to get water out of a well even when the water level is too little to get out with a pump (if you've ever sucked a well "dry", you know what we mean).  (top)

The "Slap Shot" Universal Deep Well Pump Cylinder is a great innovation in rural well-pump technology.   Collaborating with several missionary designers to bring the blueprints to reality, the SS-01 is a lift pump that easily converts to a positive force pump, which means that it can apply pressure to pump water uphill for storage or over distances for irrigation - a significant advantage over a lift pump only design.  Another huge advantage is that both valves are accessible without having to remove the riser main for repairs (and there is no extra fishing tool to get lost - it is built into the design!).  The "Slap Shot" is light weight, inexpensive, and uses off-the-shelf parts, allowing the locals to build and maintain their own pumps.  (top)

The Hydromissions® Ram Pump is a non-electric, mechanical water-pumping device that is placed in a small stream or creek to pump water up hill for storage or irrigation.  Although we have had lots of requests for these due to their curiosity, ram pumps are tricky to tune, and have (in our opinion) limited application in most of the missions environments that we typically encounter.  In light of this, rather than selling them, we have posted Free Plans for you to build your own.  (top)

Afridev and India Mark II deep well pumps:  For those of you looking for Afridev or India Mark hand pumps, please understand that although these are excellent pumps, they can be quite expensive - and ALL pumps fail over time (usually after 6-12 months - that's just the reality of mechanical devices).  If you still want to buy an Afridev or India pump, be sure to buy those that are manufactured locally (they are public domain designs, and if you go to our "Countries" page, we try to list in-country manufacturers when we find them.  Even so, understand that most villages and individuals will not have the access or the income to purchase replacement parts for such pumps - this is why Hydromissions® does not manufacture these pumps (if the locals can't sustain them for themselves, then we don't use them in the field).  If you still feel you should go the Afridev or India Mark II route, and you have the infrastructure to import and sustain them, then we suggest the following manufacturers:,, and

"Bailer Bucket" Kit.  Bailer buckets are the least expensive, most "village accessible" way to draw water from a tube well - and they still work when recharge rates are too slow for a pump!  Kit includes cross bar hardware, foot valve & adaptor, 100ft rope and pulley.  Light and compact for easy travel Click here for VIDEO



Deep well pump cylinder for Afridev or India Mark II hand water well pumps SS-01
(Clear pvc body is for demo purposes only, not for sale.  Actual pump body is white pvc)

"Slap Shot" Universal Deep Well Pump Cylinder.  Specifically designed for the third world, this cylinder uses simple, off-the-shelf parts that are locally available (the whole idea is for villagers to be able to make it for  themselves).  Adaptable to any pump head (Afridev, India Mark II, etc); both valves accessible without having to pull out riser main (No extra fishing tool to get lost - it's built into the design!).  We are so convinced this cylinder will make a difference, that we have made the plans free to the public.  Click here for free plans.  To see video of how a typical pump cylinder works, click here.  To see a video of the "Slapshot" in action and how to build one, click here.

Ram Pump.  We have had so many requests for these, that we finally decided to pursue the project.  Our conclusion, however, is simply this:  they are tricky to tune, and have very limited application.  In light of these findings, we have chosen not to sell them (but we might package a parts kit in the future).  However, we have posted "do-it-yourself" plans for making your own using off the shelf parts that you can buy at any home improvement store (Lowe's parts list included).  Here are free plans (2 files: blueprint & set up.

The Hydromissions SPADE ™(Solar Pasteurization Detector) is designed to be used to create multi-user "pasteurization stations" in small villages.  It has been known for quite sometime (especially in the dairy industry) that many liquids do not have to be boiled in order to kill harmful bacteria.  Instead, disease-causing organisms in water may be killed by exposure to lower levels of heat in a process called pasteurization.  Water that has been heated to 65ºC (150ºF) for a short period of time is free from microbes including Escherichia coli, Rotaviruses, Giardia and the Hepatitis A virus. At around 70ºC (160ºF), milk and other foods are pasteurized.  The SPADE is a simple, re-usable device that indicates when adequate temperatures for water pasteurization have been reached.

The recommended model is to collect used water bottles, drill a 1/4-inch hole in each cap, and attach one SPADE to the inside of each cap with the wax at the top.  Construct a simple A-frame of corrugated tin, painted black, and placed in full sun.  Fill each bottle with water, attach cap, and place bottle in the grooves of the A-frame.  When the water reaches the desired temperature, the wax melts and runs to the bottom of the SPADE capsule.  Simply reverse the capsule to repeat the process.  (top)

The S.W.I.M. ™(Safe Water International Ministries) CPU (Chlorine Producing Unit) is capable of producing an almost endless supply of chlorine disinfectant from simple table salt.  Basically, the unit is a funnel with a special, electrically charged membrane (the charge is via a car or motorcycle battery, or via a small solar panel).  A mixture of salt water is poured through it, and the charge separates the salt (NaCl) into chlorine (Cl) and a mixed, non-toxic byproduct.  The concentrated chlorine is then added to drinking water as a disinfectant.  (top)

Another approach is to add household bleach.  For a rough guideline, click here for a chlorination chart.

Home made biosand ceramic water filter Clay Pot (Nadi) Filter.  The same concept as a bio-sand filter, but this uses home-made ceramic pots.  Note:  this is not the same thing as a 'ceramic' filter.
Home made water ram pump plans KTM/Hydromissions® Ram Pump.  This is a classic, non-electric, self-perpetuating, mechanical device that is placed in a stream to pump water up hill for storage or irrigation.  A well-tuned ram pump can pump water up hill in an almost 3:1 (height to drop) ratio.  As intriguing as they are, they are tricky to tune and have limited application.  You can buy most of the parts at any home improvement store.  Click here for set up instructions.
Tippy tap plans for hand washing Tippy Tap.  This is a simple device to hang in a dwelling or in a latrine to promote hand-washing without a lot of excess water loss.  The water tank and soap dispenser are located together for convenience.  Remember, hand washing is the number one prevention for the spread of disease.
VIP latrine plans VIP Latrine.  The ventilated improved pit (VIP) latrine is the best latrine design that we have seen.  We prefer the double-vault structure where possible, since the pits are shallow and the waste is recycled for fertilizer.
Latrine fly catcher plans Fly Catcher.  The Fly Catcher is a simple device for capturing flies, made from a common, 2-liter soda bottle.  Since flies are significant carriers of disease, it is important to implement some measure of control as part of your overall Hydromissions program.  We recommend placing one or two of these devices in each latrine and in each individual dwelling.
Biosand cistern filter plans Alternating Cistern Filter.  If you are using a rain catchment system for water acquisition or supplementation, some form of front-end filtering is essential for keeping the system clean.  This is a simple way to set up a continuous filter between the rain gutter and the holding tank or cistern.
