Attempting to control water losses within their own infrastructure is only half the battle for water treatment and distribution organizations. To maximize water conservation, they need to involve their customers as well. Here are several ways public and private water utilities can spur internal and external changes in consumption monitoring to improve valuable water-asset management.
Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
When developers of a condominium complex sourced wastewater treatment systems, it did so with two primary requirements: efficient land utilization and high effluent quality to meet stringent guidelines. State regulators advised the developers to discuss combining its wastewater system with the owner’s association of an adjacent housing development, whose existing wastewater treatment system was aging and required augmentation.
Water quite literally flows through every facet of life, being the key element for everyone and everything on Earth. The world’s population is increasing at 1.1 percent (roughly 83 million) every year, an incredible and alarming rate straining the world’s fresh water supply. The increasing pressures between what humanity demands and what is currently available emphasizes the importance of conservation.
It has been said that the unseen and untreated can break down any system — this phrase could not be more accurate than in the world of wastewater treatment when considering the infiltration of grit into a system. Infiltration happens in the collection system, whether it’s from living on the coast, aging infrastructure or just plain old build up over time.
Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.
The City of Silverton is known as Oregon’s Garden City and sends one million gallons a day of treated effluent to the Oregon Gardens, returning the remainder to Silver Creek.
There are many facets to industrial processes — raw materials, skilled labor, well-designed equipment, and sound methodologies. Optimizing those manufacturing processes requires consistent, reliable feedback on performance efficiency and output quality. Here are several guidelines for implementing continuous monitoring to keep process integrity at optimum levels.
Potable reuse offers a massive opportunity to recover water from the wastewater process, but projects face a variety of barriers to getting off the ground. Most successful early adopters engaged early with their constituents and implemented smaller-scale demonstration projects that were accessible to the public to prove the technology and process.
Large-scale water-reuse treatment plants have had sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in those same locations.
Over the last several years the wastewater reuse segment of the water industry has experienced both rapid growth and tremendous change. Global demand for increased water supplies fuels the development of alternative water sources, including reclaimed wastewater.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.
Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.
When a municipality or business wants to reuse their wastewater, some applications require more treatment than others due to the quality of the wastewater. Many standard wastewater treatment systems consist of pretreatment, primary treatment, and secondary treatment stages. By the end of the secondary stage, a majority of the pollutants, solids, organics, inorganics, and metals have been removed or reduced. This is where reverse osmosis wastewater treatment can be utilized in a third stage process.
A Q&A with scientist Jeff Urban, who explains forward osmosis and how Berkeley Lab is pushing the frontiers of this emerging technology
Isn’t it ironic that our beautiful blue planet, covered 70 percent with water, is struggling to meet citizens’ water needs? Yes, and the reasons are obvious. Out of the Earth’s total water, less than 3 percent is available as freshwater, and a portion of it is actually accessible. Uneven distribution of fresh waterbodies and population across the globe further skew water supply and demand ratios. Also, climate change, deforestation, desertification, droughts, floods, and depletion of natural waterbodies resulting from anthropogenic and natural activities add to these miseries.
The technology is ready, but is the world ready? The seismic shift toward water reuse will occur only as driving circumstances reach their tipping point.
Everyone is familiar with the water cut statistics: three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.
Water is essential to life. And it is a very precious commodity in Israel, home to 9 million people living in a rocky desert that receives about 10 inches of rain a year. By comparison, Denver, considered semi-arid, gets about 15 inches of rain a year, which is about a fourth of the precipitation a tropical city such as Miami receives.
Water reuse has long been trending up, but where do we stand in 2019 and beyond, particularly with respect to potable reuse, which has been more difficult to implement? Andrew Salveson, Water Reuse Practice Director at Carollo Engineers, talked about adoption rates, national and regional activity, and what's on tap for water reuse in this Water Talk interview. While the West and Southwest parts of the U.S. have been faster to embrace the practice due to drought and scarcity, Salveson explains why the Northwest and East Coast, where rain is abundant, are also getting on board.
