A biogas generating plant which would be affordable and easy to maintain by the local/rural consumers was designed and fabricated with locally available materials. The fabrication was based on the laid down engineering standard and procedures in machine design and fabrication, such as proper design specifications, alignment of parts and strength of materials. Results obtained from the test showed that the plant could generate average volume of 1.58cm 3 of biogas at average pressure of 1.5bar in a day. Results also revealed that the rate of biogas generation increase with increase in time and for eleven (11) days of the plant’s test, the volume of biogas generated increase from 0.0043cm3 to 5.2510cm3 . From the results, it was observable that the more the pressure in the chamber, the more the volume of biogas generated; thus, at 3.6 bars, it produced maximum volume of 5.3cm3 of biogas. Finally, from the bill of engineering measurement and evaluation (BEME), the total cost of production was ?36,320.00 (116 USD) which could be afforded by an average consumer.
