Description:
Information
An important aspect of the cost analysis to establish a sustainable recovery rate is to optimize and maintain the O&M rates as low as possible, while still providing the sufficient level of service to properly operate and maintain the system and pay for the labor. O&M costs can be reduced in the following ways:
- Choosing a technology with inexpensive spare parts, materials, energy, staff and/or other operating costs;
- Reducing the transport costs to go and buy spare parts and materials;
- Reducing the dependence on fuel and electricity to operate and maintain the system;
- Implementing an effective preventive maintenance program to keep equipment in good working condition, rather than waiting for it to break and require repair or replacement. This may imply that a ‘maintenance culture’ needs to be instilled in the community and professional staff; and
- Installing proper administrative and financial support and control mechanisms.
