Biogas is produced in the reactor and stored in the gas storage dome, then circulated by the pipeline system. Any damages in the system may result in an irregular flow of gas usage..

Pipes used to circulate gas must be of high quality. A galvanized-iron pipe is excellent for this purpose; however high-quality PVC pipe can also be used. All pipes and accessories such as elbows, sockets, tees etc. must comply with standards of BIRU and IDBP.
