ABPA-SA is about to close the books on another year.

The members of ABPA-SA have had the great opportunity of being informed about many different aspects relating to keeping the potable water clean and safe through the use of backflow prevention assemblies. The monthly training seminars inform the members about the proper maintenance and troubleshooting techniques used to keep the many various brands and models in proper working order. They are also exposed to the operation of their test gauges and the proper care of their gauges along with a free gauge certification each year that is required by TCEQ for all gauges used to test backflow prevention assemblies. Members also have the opportunity to ask others in the industry about how to solve a specific problem they may be having with an assembly they are trying to repair and restore to its original specifications. Until an assembly is working properly, it has not been repaired satisfactorily.

The San Antonio Chapter has Expanded its Public Education

The ABPA-SA Chapter has been trying for many years to develop a public education program that would be understood by most of the citizens in our community. The members became aware of the difficulty of being able to relay information about the hazards of cross connections and the need for backflow preventers on the irrigation systems owned by many of the households in today’s municipalities. One of the members at a monthly meeting said, “If you folks come up with an idea, I can build it”. The discussion immediately started with a list of the many hazards present in a residential irrigation system. The list included hazards such as insecticides, herbicides, fertilizers, and pet and rodent excretions. The stage was now set to try and create a model that would relay this basic information to the public in a simple and easy to understand manner that was almost instantaneous, since most people will not spend more than a few seconds looking at a model.

What Causes Contamination Through Cross-Connections to Occur?

Under intended flow conditions, distribution systems are pressurized to deliver finished water from the treatment plant to the customer. However, two situations can cause the direction of flow to reverse: pressure in the distribution system can drop due to various conditions or an external system connected to the distribution system may operate at a higher pressure than the distribution system. These differences in pressure can cause contaminants to be drawn or forced into the distribution system. Contamination introduced due to backflow into the distribution system may then flow freely into other customer connections. The following conditions must be present for contamination to occur through cross-connections.

The hazards of a major flood did not prevent thousands of volunteers from helping their fellow Americans. They have given more than we will ever know.

This document addresses approaches to cleaning up residences flooded after a hurricane or other weather event. It is based on a literature search conducted using PubMed, Science Direct, the Morbidity and Mortality Weekly Report search engines, and the files of the co-authors. The report considers the types of illnesses associated with such flooding; the effectiveness, selection, use, and hazards of biocides for cleaning and decontaminating surfaces affected by the presence of microorganisms and their biofilms; and available guidance documents that provide recommendations for cleaning up after floods, hurricanes, and related events.

Spinning Biogas Into Gold With Combined Heat And Power

Glen Illyn, IL, is a fairly typical American suburb, with 27,000 residents living about 40 minutes from the bright lights of Chicago.

The local wastewater treatment plant, the Glenbard Wastewater Authority’s Advanced Wastewater Treatment Facility, is typical as well. It has a normal daily design flow of 16 MGD and peak design flow of 47 MGD. Its advanced treatment includes primary screenings; grit removal; primary clarification; high-purity, oxygen-activated sludge; clarification; tertiary treatment; and UV disinfection.

But in one key way, Glenbard is different than many other wastewater treatment plants around the country. It had grown interested in resource recovery and utilizing the influent it treated to help power and fund its operations and that interest has blossomed into an estimated $200,000 saving in annual energy costs.
