Runyanya Church

 

10 years ago, we were asked to develop a clean water source in Runyanya, Uganda , a small village north of Masindi. At that time, we were unsuccessful in locating water. There is a hard layer of limestone 40-60 feet below the surface and our equipment was not able to drill through it. In June of 2011, tragedy struck this village when their school was struck by lightning, killing 19 students and hospitalizing dozens more. We were asked again to come back and try to help. This time, with our newer hydraulic drill equipped with a special rock bit, we were able to break through and find water. The new borehole is located just down the hill from the school.

 

Standing next to the damaged school building was a church with sturdy brick walls but no roof. However, we were able to help with this also. A donor had come forth just before the beginning of our trip with enough funds to complete the church roof. At the public ceremony dedicating the new borehole to the Glory of God, CEED Director Graham Hodgetts announced our plan to provide the materials for the church roof, in the memory of the children who had died in the lightning strike.

 

The new roof was installed in time for the Easter services in April 2012.

 

 

Notes from January 2012 trip to Uganda …

  • Jatropha farm project …We visited the Jatropha farm. Plants are larger than when last seen, probably 6 to 8 ft tall. There are still 10 acres planted.  A 6.5 ft diameter by 15 ft deep tank is being installed near the river to provide a year-round source of water for irrigation. We installed a section of drip irrigation piping just to demonstrate how it can be done. The pump for moving water from the river-tank to the irrigation system has been purchased but not installed as yet.  Last year’s crop amounted to only 1500 kg (150 kg/acre). Hopefully irrigation and fertilization will improve the yield. Some harvesting takes place throughout the year.
  • Jatropha press … to extract the bio-diesel fuel oil from the seeds: We visited the Hoima machine shop that had built the press based on drawings supplied by Graham. They did a beautiful job. We tested the press and found the following:
  • Input = 12” dia x 3.5” deep bowl of seeds … bulk volume = 0.23 ft^3.
  • Output = 250 ml of oil (required about 10 minutes of press operation)
  • Assumptions: Each bag of Jatropha seeds weighs 50 kg (110 lbs) with dimensions of approximate 3 ft x 2 ft x 1.5 ft (= 9.0 ft^3). Then the approximate bulk density of the seeds is:  110 lbs/9.5 ft^3 = 11.6 lbs/ft^3.
  • Using this bulk density, the seeds we used weighed: 0.23ft^3 x 11.6 lbs/ft^3 = 2.67 lbs.
  • The oil produced = (250g)/(454g/lb)x 0.82 (specific gravity of oil vs. water) = 0.45 lbs.
  • Then the yield of oil from seeds = (0.45lbs/2.67 lbs) = 16.9%.
  • Total oil estimated from this years’ crop = (1500kg)x(2.2lbs/kg)x(0.169) =  557.7lbs.(or … 557.7 lbs at 6.15 lbs/gal = 90.7 gallons).
