Pure inspiration

. In 2014, the Santa Clara Valley Water District in San Jose, Calif., surged forward in its goal to meet at least 10% of county demand with recycled water by 2025. In partnership with the City of San Jose, the district commissioned the largest advanced water purification facility in Northern California.

 

A clear winner

. The Pima County Regional Wastewater Reclamation Department in Tucson, Ariz., and CH2M Hill (Englewood, Colo.) recently started up the first large-scale dissolved air flotation primary clarifiers in the world at its new 121-million L/d (32-mgd) Agua Nueva Water Reclamation Facility.

Chasing efficiency

Wastewater collection and treatment is a financial balancing act. Spend too little, and you risk critical elements being undersized or not properly maintained; spend too much, and you risk being labeled as a squanderer. The March issue includes several stories about utilities that spent their funds wisely. 

In “A collection system on the cloud,” a switch to mobile devices to locate and track the condition of collection systems pays off. The utility took an innovative approach that uses a mobile app for smart phones and tablets to help inspection crews locate sewer manholes and create a comprehensive inventory and survey all manhole assets. All data are stored in the “cloud” — on remote servers accessible via the Internet — and are used to develop a geodatabase and comprehensive geographic information system map. 

In “Penny by penny, drop by drop,” Baton Rouge, La., implements 110 projects worth approximately $1.6 billion involving wastewater treatment and storage, comprehensive rehabilitation, capacity improvements, and supplemental projects. The program is self-funded via a combination of municipal bonds, sewer sales taxes, and sewer user fees. The parish uses numerous funding avenues for the capital portion of the program as well as operations and maintenance of the new assets into the future. 

The article, “It’s the fibers: Attacking the wipes problem at the pump station,” examines a three-phase approach to eliminating the clogging, maintenance costs, and safety issues caused by nondispersibles. By studying the behavior of wipes in pump stations, utilities can find most cost-effective solutions to minimize maintenance needs and ensure as much equipment uptime as possible. 

  

Also in this issue:    

  • Dig it. Large decentralized wastewater treatment system installations increase in popularity as lower-cost, high-efficiency solutions.   
  • Backyard BNR. A passive nitrogen reduction system shows promising results for onsite wastewater treatment.   
  • Building with biosolids. Researchers seek to extract cellulose from residuals for reuse.
