Hi Dan, I am not surprised ...

Hi Dan,

I am not surprised that your W&WWT sites are very energy intensive.  In fact, the 2nd biggest expense for such facilities is energy cost after staffing; and ironically pump and motor systems are the biggest culprit toward this expense.  Good thing is that you are addressing this issue.  RE generally comes after implementing energy efficiency measures (EEMs) and demand side management (DSM).  EEMs help reducing both energy usage and associated costs while DSM helps operators reducing energy costs by shifting consumption from on-peak hours to off-peak hours, if the facility is on such tariff structure.  If you don't implement EEMs, RE simply reduces your demand on the grid electricity but doesn't reduce consumption.  A few years ago, I managed a program to reduce energy consumption at California's W&WWT facilities; and frankly the out come was very impressive.  So I think I can guide you where to start from and how to get to the end point.  If you are interested, please contact me: sfc95823@yahoo.com.  By the way, I am not selling any services or products; just trying to help you using my extensive experience in this field.
