With electricity consumption being a primary operating cost in water treatment and wastewater treatment, steps taken to optimize energy use are critical. Saving energy is more than just an on/off decision. Monitoring and managing energy use — from analyzing pump curves, to reducing non-revenue-water leaks, to scheduling operations around premium-rate windows — is essential. Fortunately, the payback potential can be impressive.

Reasons for changing water or wastewater asset management practices include unacceptable process downtime, statutory requirements for documenting infrastructure integrity, or the desire to refine process cost-effectiveness and maintenance-budget ROI. Here are examples of strategic approaches that can better match desirable asset management outcomes to the real needs of water utility operations.
A variety of research indicates that industry loses 3 percent to 5 percent (and in some cases more) of its productivity annually to unplanned shutdowns due to equipment failure. With all the data and connectivity available through today’s Industrial Internet of Things (IIoT) technology and SCADA systems, water and wastewater treatment operations can reduce those losses significantly…if management is willing to consider and adopt proven strategic approaches.
The cost of water delivered to customers is as much about the energy needed to move it as the chemicals required to treat it. Balancing water chemistry, infrastructure costs, and energy consumption is key to optimizing the overall cost of operation. Experience shows that some astute water suppliers are closer to achieving their ideal outcomes than most people realize. Here are some insights into how that works.

Steinbach is the third largest city in Manitoba and one of the fastest growing census agglomeration areas in Canada with a population of about 50,000 people. Though Steinbach is primarily an agricultural community, it is also the regional economic hub of southeastern Manitoba. Due to the age of the wastewater control system, the city decided it was time for some new technology. This profile will describe the process of that upgrade and why they chose VTScada.
The European Commission’s Aerosol Dispensers Directive (ADD) legislation (UN ADR 2013, 75/324/EEC) mandates that aerosol dispensers and small receptacles containing compressed gas (gas cartridges) must pass a leak-proof test before they are transported. Cascade’s CT2211 leak detection system detects and rejects leaking aerosol cans up to a rate of 500 cans per minute. The system is contactless, ensuring minimal product damage or contamination. With the increasing number of safety and quality standards required, Cascade’s CT2211 will ensure current and future regulatory compliance.

Most estimates of global mean sea-level rise this century fall below 2 m. This quantity is comparable to the positive vertical bias of the principle digital elevation model (DEM) used to assess global and national population exposures to extreme coastal water levels, NASA’s SRTM. CoastalDEM is a new DEM utilizing neural networks to reduce SRTM error. Here we show — employing CoastalDEM — that 190 M people currently occupy global land below projected high tide lines for 2100 under low carbon emissions, up from 110 M today, for a median increase of 80 M.
