Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.
The road to net-zero
Wastewater treatment is energy-intensive. Energy
typically accounts for one of the highest costs for water resource recovery
facilities (WRRFs). When you factor in that U.S. domestic wastewater contains
five times more energy than currently is required for treatment, equipping
utilities with a road map to net-zero energy makes good sense.
Thermal hydrolysis tips from the trenches
After becoming established in Northern Europe,
thermal hydrolysis process technology is gaining momentum in the United States.
U.S. water resource recovery facilities now considering the benefits associated
with thermal hydrolysis can take advantage of the experience gained by European
water companies with established THP operations.
Drought's silver lining
Despite its many drawbacks, drought can spur
water reuse and conservation acceptance

Keeping water services flowing
requires making sure utilities have a sufficient supply of another type of
liquid asset: funding. Aging infrastructure, tightening regulations, growing populations,
and changing climate all put more pressure on the financial side of utility
management. Luckily, new programs, products, and strategies exist to help
smooth things out. But like all new endeavors they require taking the time to
Public–private partnerships (P3s)
have gained traction during the past 18 years as public entities have pursued
private funding, construction, or operation of infrastructure. A P3 is a
contractual relationship between the private and public sectors with each side
bringing certain skills and assets to bear and each side sharing the risks and
rewards. Several states have enacted P3 legislation to establish parameters and
facilitate such delivery approaches.
However, P3s do not always succeed.
Common challenges include less-than-optimum planning, procurement, and
contracting. But when fully considered and implemented, P3s can lead to
successful outcomes regardless of the type of infrastructure.
Also during the past few decades,
data have shown that weather is becoming more intense and frequent. To prepare
for this, utilities must forecast what’s coming, create plans to cope, and then
find a means to pay for those changes. The U.S. Environmental Protection Agency
has created guides to help with forecasting and planning. Utilities are
collaborating to find means to cope. And the U.S. Federal Emergency Management
Agency can provide some federal dollars to fund it.

- Good riddance. A New Jersey facility controls
its foaming problems with simple, yet effective, techniques.
- More efficient, enhanced biological phosphorus
removal. Balancing design and operations makes the process more reliable.
- It’s better in 3-D. University researchers
create a nitrate detection kit using 3-D printer, open-source hardware and
software, and leafy greens.
