SUEZ is a full service provider focused on providing more efficient water and wastewater treatment systems for all of our clients. We implement regular testing in order to make sure that our systems are working at peak efficiency. We also have web based tools that convert data on water levels, pumping rates and power consumption into a simple and easy to read graph to better gauge pump performance over time.
We also offer rehabilitation services in terms of the environment. Artificial wetlands are often formed nearby wastewater treatment plants in order to provide a place to naturally combat micro-pollutants, limiting their diffusion into other water sources. When biomes such as this fall into disrepair due to neglect, our rehabilitation services can redesign and make improvements to the area to keep taking advantage of the treatment capabilities of the natural environment.
Rehabilitating Our Resources in Rockland and Orange County, New York
SUEZ operates 61 wells and two water treatment facilities in Rockland and Orange counties. Each month, operators evaluate the energy use and operational performance metrics of each of these sites, as well as the many booster stations, in order to optimize the overall system operation and select the most efficient pumps and equipment. As required by the state of New York, SUEZ completes comprehensive well and pump performance tests on all wells every three years which includes pump efficiency testing. Typically about a fourth of wells tested are found be prime for replacement and result in energy savings.
SUEZ has developed an innovative key performance indicator tool to monitor and evaluate the efficiency of wells and well pumps, including power consumption of the well pump. An efficiently operating well and pump combination will provide the most energy efficient use of a groundwater supply source. Within minutes, the web-based tool converts data regarding water levels, pumping rates, and power consumption into simple and easy to view graphs that show well and pump performance over time. Pumping rate and water level data are converted to “specific capacity,” which is the pumping rate divided by the water-level drawdown, in order to track well efficiency. Pumping rate, water level and pressure are converted to “total dynamic head” which is a measure of the well pump’s ability to pump water. Data is automatically plotted on the well pump curve to evaluate current efficiency of the pump.
As we continue these three year cycles of pump checks, New York State Energy Research and Development Authority funding is secured to offset the cost of installing new equipment. Replacing or rehabilitating the pumps typically results in 10 to 30 percent energy reduction.
