Our Project

y Project Lead : Ana Heureux andDanielle Dahan

y Problem Statement :Provide a less expensive, easily accessible alternative to currentmethod of providing water with

barrelsEffectively catch and store 1,200 Lof water from the long rains untilplantingCost cost of 4 barrels ($23.20)

Parameters

y Last for one planting seasony Allow for easy repairs in the

futurey Locally available materialsy Ensure farmers are capable of

construction with instruction

manualy Easily replicated and scalable Danielles host mom, Beatrice, by the creek in Ganzetown

Prototypes: Three New Designs

Prototype 4 (X-farm):Base = 1 x 1 mTop = 3 x 3 mDepth = 0.5 mSlope =

V olume = 2,200 L

Prototypes 2 and 3 (Mbao, Silvesters shambas) :Base = 1 x 1 mTop = 2.5 x 2.5 mDepth = 0.75 mSlope = 1

V olume = 2,500L

Future Goals: Evaluation and Implementation

y Project Lead: Scotty Evaluation:

Measure the water depth of

each prototype each week after filling

harvester to capacity Input water depth into excelprogram to determine total water volume and harvesterefficiency as a function of time

Assessing harvester prototype #3

Additional Projects with KOMAZA

y Off-the-grid water sanitation research for KOMAZA office in Ganze

Compostable Toilets

y KOMAZA Wiki Project developmentKOMAZA previously had no method of knowledge transferHigh staff turn overDevelop and organize wiki for new employees for easy

understanding etc.
