An ageing wastewater treatment infrastructure may force operators to make difficult decisions between revamping or replacing the older infrastructure with new technology. However, in such cases, evaluation is very important. When a correct evaluation of the existing facility is done, the operators can figure out if repairing is a viable decision or replacement of the technology is feasible.
Some of the factors that help plant operators come up with a proper decisions include:
- The condition of the existing facility – In circumstances where the facility does not show any notable depreciation, a careful investigation of other factors must be done to establish the ideal course of action. With many facilities sometimes functioning beyond their intended life, even when the existing technology can be refurbished, it may be more reasonable for it to be replaced.
- Availability of space – Sometimes, to have successful modifications, it would require an extension of your physical plant. Likewise, replacement with new technology may also require a footprint that exceeds available land. In other word, operators here must opt for the most ideal option.
- Costs of a repairing versus constructing a new facility – Sometimes, a less costly repair option for an ageing facility is preferred due to inadequate funding for full replacements.
- The impact of ongoing plant operations – It might be prudent to determine the period it will take to have a smooth switch from one technology to another. In some instances, retaining the operations of the existing facility until the new technology is implemented and fully functioning is a viable option.
- Age of existing infrastructure – At times, a facility might be too old until the only option left would be to replace it.
