The services rendered shall ensure that appropriate unit scale and installation are adopted with due consideration to factors such as the amount and type of collected solid waste, installation location, and safety measures.

Scope of Work

The following activities will need to be undertaken to help meet the objectives of the project.

Detailed design, structural engineering, and safety assessment: 

  • On-site assessment of the civil structural integrity of the building where the community-scale biogas digester system will be installed and identify the safe distance from waste sources (i.e., from households, waste-disposal point) so that the methane gas can be distributed to at least 5-10 beneficiary households.
  • Detailed engineering design including chemical, thermal, energy, and civil works for the installation of a biogas digester system for Bogor City and ICLEI review.
  • Service providers that can provide methane gas analysis are preferable or advantages.
  • Providers supplying any biogas digester system sourced outside of Indonesia are required to provide a permit letter in terms of installing and operating the biogas digester from the relevant Indonesian Government Agencies, as well as proof that the spare parts are available locally. Please see sections 3 and 4 for the list of qualifications and required permits and documents.
  • Preferably, but not required, conduct composition analysis of methane gas captured

Procurement of unit components and other materials, fabrication, set up, and installation

  • Procurement and fabrication of 5 m3 biogas digester system are not limited to the following aspects:
  • 50 m3 digester tank/reactor along with pipes and pipe network
  • Flow meter
  • Biogas stove
  • Any other relevant components needed to ensure the facility’s operability and functionalities
  • Provisions of spare parts and components
  • All activities associated with the structure, such as procurement, erection, installation, and commissioning of the 5 m3 biogas digester system in the project site.
  • In case there are any changes in the above components, consultation and approval from ICLEI and the city should be carried out first before proceeding with the purchasing material.

Operation & Maintenance (including warranty period)

  • Monitoring and regular maintenance of the facility for at least three (3) months after completion of set-up and installation.
  • The service provider also assumes liability for the manufacturer warranties of the respective system components/parts.
