When community and infrastructure collide

feature 1 art - nov'14 Many water infrastructure projects require public outreach. Typically, stakeholder groups are brought into the development process and educated about water infrastructure requirements and challenges. From this process, their input helps to guide design and construction. Once the project is completed, the interaction typically ends. However, a recent project for the City of West Sacramento, Calif., embraced these valuable community water infrastructure elements as an educational outreach opportunity to inform customers and provide an asset, instead of a liability, to the surrounding community. 

 

Floating a fix

feature 2 art - nov'14 When it rains, roadway runoff has to go somewhere. In many cases, it is conveyed to a nearby receiving waterbody through such secondary drainage systems as culverts, ditches, and canals. Along one stretch of road in the northeast part of Orange County, Fla., the Bates Road Canal carries runoff from surrounding neighborhoods, businesses, upstream areas, and Bates Road itself. Because of severe erosion, the canal was in danger of becoming a safety hazard.

Water rights … even after it leaves the pipe?

San Antonio Water System petitions to retain ownership of treated effluent after it enters the San Antonio River    

In the drought-ridden Southwest, water has become increasingly coveted. Those who have it want to protect it. The San Antonio Water System (SAWS; San Antonio) is doing just that. SAWS filed an application with the Texas Commission on Environmental Quality (TCEQ) for a “bed and banks” authorization to transport high-quality treated effluent to the San Antonio Bay, according to a SAWS news release. Essentially, the application secures SAWS ownership of the wastewater it treats even after it leaves the water resource recovery facility.

Details make the difference

Sweating the small stuff may cause some headaches, but it also produces reliable results. With ever shrinking permit limits and tighter budgets to meet for energy and chemical use, excess is the enemy. Not only does paying attention to details yield better outcomes, it can even earn you a trophy. 

Aeration energy always is listed as one of the top expenses for water resource recovery facilities. Great pains are taken to ensure proper motor configuration, the correct diffuser selection, and efficient operations using varying levels of process control. One other area that deserves attention is piping the air to the diffusers. Misaligned pipe joints can lead to air leaks and increased energy costs during operation. One option to ensure more custom-fitted joints are mechanical couplings. These couplings serve triple duty in that they join the pipe, handle misalignment, and accommodate thermal expansion and contraction without the need for specialty devices. 

Also in the December issue, is a full report on Operations Challenge 2014. WEFTEC 2014 in New Orleans hosted the 27th annual competition. During the 2-day competition, 43 teams battled through five events to see who would reign supreme. After paying attention to the smallest details in safety, process control, laboratory, collection systems, and maintenance events, Terminal Velocity from the Virginia Water Environment Association earned an unprecedented fifth consecutive win in Division 1. Team HRSD, also from Virginia, earned the Division 2 title.
