Conversation at the 2016 SESWA Stormwater BMPs, LID and Green Infrastructure Seminar in Atlanta GA that I attended recently touched upon the idea of computers taking our jobs and ‘Engineering Bots’. This has of course happened in other industries, but I didn’t anticipate it happening in the stormwater planning, design and management world.
Once discovering its main pump station was at risk, a critical Canadian wastewater treatment plant quickly set up a large bypass pumping system to allow the replacement of pump motors.
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.
United Water, a division of the global conglomerate Suez Environement, operates regulated water systems in eight states, and provides contract services to over five million people.
More than 6,800 cubic yards of structural concrete are being used in the construction of a new Trickling Filter and Trickling Filter Pump Station in Bismarck, North Dakota. These structures are being built well below the area’s water table, and the more than 6,800 cubic yards of concrete will protect them against the effects of Mother Nature.
200-acre Monmouth Park Racetrack in Oceanport, NJ, is supported by a series of barns and other support facilities that house in excess of 500 horses during track operations. In the mid-1990s the New Jersey Sports and Exposition Authority (NJSEA) constructed facilities to collect horse wash water and first flush stormwater runoff for conveyance to the Two Rivers Water Reclamation Authority (TRWRA), a wastewater treatment facility located in Monmouth Beach.
A Bergen County, NJ, riverside town receives relief from torturous flooding after its stormwater pumping station is dramatically improved by the installation of new Flygt pumps.
The district manager for the Pinetop-Lakeside Sanitary District (AZ) reports that a special gas chlorination system, featuring unique components and controls, and manufacturer-supplied service, has effectively replaced a chlorine tablet system.
In Iowa, where agriculture is a critical component of the state’s economy, rain is good for crops, but too much rain is not good for anyone. In 2008 the Des Moines Metropolitan Wastewater Reclamation Authority (WRA) retained consulting engineer HDR to provide planning, permitting, design, construction, and start-up services for a high-rate CSO treatment facility called the Combined Sewer Solids Separation Facility or CSSSF.
Telog Instruments, Inc. offers a comprehensive remote monitoring system, Telogers, for wastewater collection system operators. Telogers provides an automated system of collecting, archiving, analyzing, presenting, reporting and sharing data from collection system remote assets such as flow meters, rain gauges, CSO/SSO surcharge sensors, lift stations, pretreatment water quality, air quality, and pressure sensors.
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
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.
Clay County, located in Northern Florida, has a population of almost 200,000. In April 2016, Clay County Utility Authority (CCUA) needed a new SCADA system to monitor seven reclaimed water sites that the Authority uses to determine water storage times, using this data to route water from site to site. VTScada was selected by CCUA and their engineer.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
Though they all must support routing functionality, some devices do it better than others.
Routing consumes more energy, so the lifetime of the battery will be affected. Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.
Rising energy prices have made accurate energy measurement a hot topic in recent decades. The need for accurate measurement technologies extends to many different application areas, including heating and cooling; compressed air; steam production and distribution; heavy fuel oil consumption; energy monitoring; and custody transfer. In response, new technology is being developed that integrates tasks previously requiring several measurement devices.
Process design in water treatment is historically confined to proprietary or user-defined spreadsheets on a unit operation basis, with users manually adding results from each unit process upstream into the next operation.
A new federal funding program seeks to help utilities complete their infrastructure projects. But what stands between a potential borrower and the available funds?
The Water Research Foundation recently completed a project assessing alternative funding options to cover the increasingly necessary costs for water infrastructure upgrades. Are there options that will help your utility avoid raising rates?
With Environmental Impact Bonds, everyone can win. Shared risk means there are no big losers even if the project falls short.
Satellites provide the latest, perhaps most efficient, method for spotting underground leaks, ushering in a new era of non-revenue water management.
What’s the right flow measurement method for your operation? A leading independent lab breaks down the options and considerations.
Understanding risk is the first step to combating system failure and protecting the public and the environment from unsafe water.
