O&M costs higher than expected

Dear SuSanA members, 

Could some of you please share with me sources where they found out that the O&M costs were higher than it was initially planned? 

The reason, in a research that I am carrying out I am performing a sensitivity analysis and I want to evaluate how the final costs of different scenarios will be affected by additional O&M costs than the ones initially estimated.

Factors like increase in energy costs, labour costs, among others (that you might know better than I) affect the O&M costs and can impact the final total costs and thus, the decision making process of which would be the best wastewater management scenario. 

Thank you very much!!

Regards, 

Sara

Re: O&M costs higher than expected

Hi Sara,
Which O&M costs do you mean? Do you mean for wastewater treatment plants?

If so, do take a look at this thread:  Data for costs and build-out rates for conventional sewer systems

Or, in general, our sub-category on  Financing (taxes, tariffs, transfers) and cost estimates

Hope this helps.

Dear Elisabeth, 

Ohh sorry!! I forgot to cleaar that. I mean for wastewater management systems (basically WWTP, sewer network, pumping stations). 

Thanks a lot for your answer!
