1meribah-ram-pumpPoblaki Ram Pump Installation ReportPrepared by: Jennifer TracyOn January 22, 2008 the Thai-Karen villagePoblaki (aka Dok Mae Sot) received a ram pumpproviding water to the village primary school.This is the first permanent ram pump installationcoordinated by BGET. Poblaki is a 4 hour drivenortheast of Mae Sot located in Tha Song Yangdistrict. The ram pump provides approximately1500 liters of water each daof approximand Thai resident for ovethe ram pump in Bangkok, Thailand to BGET and offeredto install it with his insta team, consisting of an Austrian and twoinaryAndrew Pteam performed a second site assessment,confirming and updating the prior data anddetailing out the specific materials needed to complete the install. A path was cleared forthe future placement of the pipeline and the location forthe pump and the initial water collection tank whereleveled.In the evening on January 17ththe BGET teamreturned to Poblaki. A meeting was held to coordinateamong the villagers the following days work. OnB G E TB G E Ty for the village schoolately 130 students.The installation was funded and led by RalfOberg, the German-born CEO of Meribah Pumps,r 20 years. Ralf donated, which he manufactures locallyllation and developmentother Germans: Phillip, Stephan, and Thomas.The project was completed in five stages.The initial stage took place in May 2007, whenthe site was first discovered and prelimmeasurements of water flow and location whererecorded by Watit (BGET Technician) andascale (past BGET volunteer).On January 14ththe BGET team, includingThai (Technician), Sunti (Technician), Surat(Technician), and Jennifer (volunteer) and Ralf’sBORDER GREEN ENERGY TEAMB G E TBORDER GREEN ENERGY TEAMPoblaki village schoolRalf Oberg describing to the villagers thelayout of the ram pump installation.The BGET ram pump installation team: Thai, Sunti, Jennifer, and Surat.
2January 18ththe BGET team and 30 villagers worked together throughout the day onseveral construction activities:A dam at the water source was constructed to join two separate water flows and acatchments devise made of bamboo was secured to the pipe end to filter out large debris,the water will be collectedA 300 liter cement water collection tank was installed, wherebefore it falls to the ram pump,
3The cement foundation grounding the ram pump was laid,Eighteen meters of 4” PVC pipe delivering water from the source to the collection tankwas laid out,
4The drive pipe, a 1” steel pipe falling a height of 6 meters, over a distance of 12 meters,from the water collection tank to the ram pump, was installed, andA path for the water delivery pipe was cleared, spanning from the ram pump to the school,336 meters.
5Three days later, on January 21st, after the previous cement work settled, the BGETteam and Ralf Oberg’s team return to continue the installation. The 4” PVC pipe wasextended to reach the water collection tank and the pipe was covered with soil to preventfuture damage from exposure. A wire and bamboo screen was created to cover the watercollection tank to keep out debris. And a over flow hole was created to direct excess waterfrom the collection tank back to the stream.
6The drive pipe sending water from the collection tank to the ram pump was fixed infour locations with cement, stones, and iron bars to hold the pipe steady from thevibrations received from the ramming motion of the pump.
7The fine tuning of the ram pump, changing angles, ball size (functions as the valveclosing and opening the pump to create water pressure in the pipes that drives the waterup), closing of the snifter (air hole that equalizes air inside the pump), and a little troubleshooting to get it all working properly was diligently done by Ralf’s team.
8The ½” delivery pipe, distributing the water from the pump to the school spannedapproximately 336 meters and ascended roughly 70 meters. The initial 60 meters ofdelivery pipe are steel pipes, more resistant under pressure received from the ramming ofthe pump motion, and the remaining portion PVC pipes were used. The steel delivery pipewas fixed with cement, stones, and stakes, every 3 meters, and the PVC pipe was fixedevery 6 meters, again to secure the pump from the vibrations received from the pump. ThePVC pipe was then covered with soil to prevent damage from exposure.After the initial installation the water delivered to the village school, filled a water tank at arate of ½ liter per minute, approximately 700 liters per day.
9Four weeks after the pumps installation, on February 18th, Ralf, his team and theBGET team returned to check up on the pump. Upon arrival, we found that the watersource was discharging less water due to the dry season affects, and coupled with thepump’s current settings, was not functioning. Alternations were made to the snifter valveand a solid steel junction, connecting the drive pipe to the pump, was put in place of theexisting flexible connector (the flexible connector moved too much in response to theramming motion, losing valuable energy). With these alternations, the pump began towork, delivering even more water to the school, 1.2 liters per minute, over 1500 liters ofwater per day. This number is more than double the original output of 700 liters.On behalf of the BGET team, thank you to all the Poblaki villagers and Ralf and his team.
