The Water and Energy Nexus

Energy Efficiency is in our blood

There is a true nexus between water and energy. Namely with the realization that every gallon of water delivered to our customers requires a certain amount of Energy and Power to deliver it. This electrical component is large and accounts for one of the single greatest direct costs associated with water production. Energy and Power are mainly consumed in the pumping of water, but are also part of the treatment processes as well.

We have over 130 water pumping systems totaling nearly 9,000 horsepower. As such - it would cost over one million dollars a year in electricity to provide this valuable resource (2015 figures) if Mountain Regional Water did not utilize efficiency and conservation measures in its operation.

The chart below shows what would make up the 2015 Energy and Power bill without any conservation or efficiency programs. The base bill would be $1,037,687 dollars. Through all of our efforts the annual Energy and Power bill is now reduced to $644,875 dollars!
Savings achieved are as follows:

Power and Energy Management (How we operate our systems to maximize efficiency)
$298,333

Water Management Savings (Our vigilant efforts to locate leaks and water losses)
$57,983

Customer Water Conservation Efforts (Reducing water demands, i.e. landscaping efficiency)
$36,496

TOTAL SAVINGS EFFORT in 2015 = $392,812 dollars

Realized Annual Savings of $392,812 - (Based on Original $1,037,687 Energy and Power Bill)

Case Study

Mountain Regional has been on the "cutting edge" and one of the leading examples of energy efficiency in water delivery systems in the state. We have received national awards for our continuing efforts. Our personnel have been involved in many training and technology transfer studies. The State of Utah recently completed a case study regarding the efforts of Mountain Regional Water. The study can be accessed below:


District Control Strategy (SCADA)

Mountain Regional has implemented a state of the art water system control and security system (SCADA) to assist the District in the energy efficient operation of its numerous pumps and other assets. Without this technology, we would not be able to achieve the cost savings as listed above. Through the proper design and programming of this system by our professional and technical staff, we are able to meet much better our sustainability, reliability, and quality goals for the distribution of water to our customers.

Energy and Power Presentation

Mountain Regional Staff have presented many presentations on energy efficiency in the water industry. Here is a technical presentation (geared more for the engineering field) describing the techniques and process used by Mountain Regional and others to become more energy efficient and save significant amounts of money in their operations.


Energy Conservation Manual

Our work in energy and power management in the water supply and distribution field is cutting edge, and has literally led us to the point where we have "written the book" on the many possible processes and opportunities for cost savings and efficiency in this industry. This again is more geared to the technical and engineering field. Click on the button below to download the, "Water and Energy Efficiency Handbook":
