Time to repost it with a couple of additions, if for no other reason that everyone with a small stream should have a hydraulic ram-pump to irrigate pasture and garden, and to supply stock tanks so the animals can be fenced out of your downstream neighbors water supply---and keep the nitrates in the pasture where they will do some good. Not everyone has a stream large enough or with enough fall to operate a conventional hydraulic ram-pump. There are a couple that will operate with as little as six-inches of head. One of them is the Mitchell Float Pump which utilizes a common fifty five gallon barrel for a float housing. The construction details and pumping capacity is illustrated in Mother Earth News, Issue #43, January-February 1977, Page 104. A modification of a VITA hydraulic ram-pump is also fully described in Mother Earth News No. 155, April-May, 1996, Page 44, made from off-the-shelf steel pipe and pipe fittings. The clack-valve requires mounting a tee-fitting in a lathe to machine a seat for the valve. In another MEN issue, there is a ram-pump made of PVC pipe which would be somewhat cheaper. (Issue #57, May/June 1979, page 120) This then required $58 of plastic parts---I haven't costed them out, but I suspect the price would be the same or cheaper today. http://www.hostmasters.net/ram/lhhrsale.htm Low head ram http://www.ruraltech.com/hrp.html (india homemade from metal pipe) http://www.unep.or.jp/ietc/Publications/TechPublications/TechPub-8d/pumps.html (picture of snifter valve in operation) http://www2.ncsu.edu/eos/service/bae/www/programs/extension/publicat/wqwm/ebae161_92.html (NCU, pumping rates, some sources) http://csf.colorado.edu/archive/1999/permaculture/msg01621.html (Platypus Pump by Lawrence London DIY) http://www.rampumps.com/ http://www.tew.org/development/solar.water.heater.html (Ladakh jerry can water heater) http://www.tew.org/development/water.pump.html (good, durable homemade hydraulic ram pump) http://members.iinet.net.au/~steveb/stirling/st_pump.html (Fluidyne pump operates on heat or solar to pump water). http://www.oas.org/SP/PROG/chap110.htm (numerous types of pumps in third world countries) http://www.marksnyderelectric.com/catalog/waterpoweredpumps.html (HiLifter water-powered pump) http://www.mayabooks.ndirect.co.uk/water2.html (Maya books, two on DIY hydraulic ram pumps) http://forums.cosmoaccess.net/forum/survival/prep/handass.htm ($20 hand pump, make in 20 minutes) http://www.redrok.com/water.htm#ram (Redrok, bubble pump, waterwheel generator/pump, floating turbine pump.) http://www2.ctahr.hawaii.edu/biosystems/BE351/351-3-4c.html (different pump types, calculating HP, flor) http://www.pump-zone.com/messages/messages/2789.htm (caclulating wire size for electric pump) http://www.pump-zone.com/messages/messages/2800.htm (maximum run of wire) http://www.fws.gov/r3pao/ashland/mtan/mtan_28.html (raising walleyes, and reference to Rife Slingpump)
