  • the substantially clean water 16, on its way to the holding tanks or pond 30, is made to first traverse a first turbine assembly 40 and such traversal causes the generation of electrical energy or electrical power 48.
  • the turbine assembly 40 includes the combination of a turbine 101 and a generator 102 and the moving water 16 causes the blades of the turbine 101 to move, and such movement is transferred to the generator 102 which causes the generator to generate electricity or electrical power 48.
  • the obtained organic material 36 is transmitted, in one non- limiting embodiment, to a digester assembly 50 (e.g., comprising in one non-limiting embodiment, a plurality of holding tanks) and the organic material subsequently produces digester gas 55.

  • Both of the turbine assemblies 40, 60 operate under the direction and control of controller assembly 70 and may each be selectively connected to the power grid of the municipality where the generated electrical power 48,62 may be sold and utilized.

If no water 16 flows trough assembly 40, electrical power 48 is not produced.
  • the control assembly 70 is coupled to valve 130 by bus 131 and by use of valve 130, assembly 70 either allows or prevents the emitted gas 55 to enter the turbine assembly 60. If no gas 55 flows through assembly 60, no electrical power 62 is produced.
