Water Utility Pumping Stations and Filtration Plants are heavily reliant upon the electric power grid, and therefore it is often desirable to closely monitor the quality of the incoming power.  As a general rule, NRI has always offered basic power fault tracking at all Telemetry-monitored stations.  However, at certain critical stations, it is desirable to Read More →

Historical Data Presentation is one of the primary functions of a SCADA System. Today, I am excited to introduce a significant upgrade that extends the usefulness of the History Database Module of your SCADA System! — a new, powerful Data Export Module that provides the Operator and his Civil Engineers with access to raw, time-stamped data. The exported Read More →

In rural areas — due to a combination of long power transmission line lengths and the relative isolation of the remote pumping facilities — it is not uncommon for stations to suffer from power quality problems.  Therefore, it is always recommended that a station’s power status be monitored, trended, and alarmed for outages. In the most basic sense, Read More →

I am very appreciative of all the positive feedback that I’ve received over the past few days as a result of this 3-part series of articles: Part 1, Part 2, Part 3.  I am glad that I was able to convey how the latest VFD technology — when leveraged to its full capability and coupled tightly with our new VFD & Energy Analytics Telemetry Software — is Read More →

Yesterday, in Part 1 of this series, we reported that a recent pump station upgrade resulted in a staggering energy cost reduction — reducing the average electricity charges from $345/month to less than $114/month!  Since you have kindly returned today for Part 2, your consideration will be repaid with the details of how this feat was accomplished — and how Read More →

A topic of continual concern for today’s water utility is Pumping Station Energy Efficiency. And to put this subject in laymen’s terms, how better than to relate it to fuel efficiency for the familiar automobile?    First, let’s look at the work that each produces — With a car, the unit of work is expressed as a driven “Mile”; whereas in Read More →

A water utility SCADA system contains a wealth of historical data — data which is often needed for the completion of monthly EPA reports.  Historically, these reports are prepared by hand with pen-and-paper — or by manually typing values into a computer form document.  However, this article details a vastly-improved, semi-automated method of report generation in which the SCADA system Read More →
