Conference on high-strength wastewater
The Ohio State University Extension will sponsor the Ohio Water Quality and Waste Management Conference April 11-12 at Woodlands in Cleves. The topic, high-strength wastewater, will feature a sand bioreactor developed at the university to treat wastewater from an Ohio poultry plant. The low-cost, odorless, park-like system has saved the Harrison facility more than $10 million over conventional treatment. A field trip will introduce regulators, designers and installers to the system. Visit http://setll.osu.edu/programs/owqwm_conf.html for a program schedule and registration form.
An article in the fall Ontario Onsite Wastewater Association newsletter alerts service entities and system designers to the effect of home dialysis on onsite systems. A treatment, often done every other day to cleanse toxins from the blood due to kidney failure, uses 100 to 1,264 gallons of water. The significant flows can upset the septic tank, flushing solids into the drainfield and precipitating failure. Author Brock Cross, project manager with Gunnell Engineer, suggests increasing the size of the septic tank or installing a pump chamber if the original vessel is large enough. He also advises inspecting the health of the field. Dialysis does not release contaminants. The bulk of the flow is purified water from pre-dialysis reverse osmosis filtration. The remaining fluid carries wastes found in urine, and the concentrations of chemicals in the dialysate are low due to dilution.
Antibiotic-resistant bacteria in wastewater
A study by the Maryland Institute for Applied Environmental Health found methicillin-resistant Staphylococcus aureus in wastewater entering two mid-Atlantic and two Midwest treatment plants. Onsite systems also could become contaminated as home and hospice care replace hospitals. The risk of infection exists for pumpers cleaning septic tanks and installers rehabilitating systems. Researchers found that only UV disinfection or chlorination destroyed the superbugs. They encouraged operators and service providers to wear gloves and wash their hands frequently.

Minnesota Pollution Control Agency staffer Barb McCarthy reports that St. Louis County installers have adopted best management practices (BMPs) to help keep water from freezing in the 2-inch pressure pipe just after it leaves the pump tank. This portion of piping can sag as the ground settles, allowing ice to accumulate in the dip when the pump shuts off and effluent drains back to the tank. Enough ice will plug the system.
To avoid the situation, installers tamp down the backfill, especially beneath the pipe outlet. Then, they install a length of Schedule 40 4-inch pipe (less prone to bending) from the tank to the undisturbed soil, and use a reducer adapter to attach the 2-inch supply line. Workers also insulate at least the upper portions of tanks with foam board or spray foam (the latter doesn't leave gaps and also will insulate riser lids). Finally, they cover the dispersal mound with straw or other insulating material.
Electronic plan review
The Wisconsin Department of Safety and Professional Services (DSPS), Division of Industry Services, will accept onsite design plans electronically. After registering for access, designers can upload required documents in PDF format, then follow the status of the review through SharePoint communication software. "The agency wants to ensure that our profession is reasonably regulated without multiple agency staff duplicating responsibilities and slowing down the process," says Aaron Ausen, president of the Wisconsin Onsite Wastewater Recycling Association. "DSPS wants us as qualified professionals to make our own decisions."
NOWRA is completing development of an advanced onsite system design course at the request of the Maryland Onsite Wastewater Professionals Association. The project stems from state Department of Environment regulations requiring best available technology units for all new construction. The law became effective Jan. 1, 2013.
"We saw a big need for the course," says NOWRA executive director Eric Casey. "Many engineers contracted to design systems have little experience with pretreatment. It's usually the soils that trip them up." Numerous Maryland health officials responsible for approving, inspecting, and certifying advanced designs also will benefit from the training.
MOWPA board members, which included representatives from the state Department of Health and Mental Hygiene and MDE, reviewed the curriculum. NOWRA members Dick Otis, P.E., Bob Mayer, P.E., and Hilary Valentine, an instructor at Delaware Technical Community College, developed the course. They incorporated material from sources including the Consortium of Institutes for Decentralized Wastewater Treatment, Michigan State University, soil science and engineering communities, and elsewhere.
Otis and Valentine planned to present the first course April 23-24 and May 1. It includes classroom studies and fieldwork in which students will design two systems using alternative solutions. Two more field exercises and an exam follow in May. Visit www.mowpa.org.
In the future, NOWRA will offer a train-the-trainer course, enabling others to present the advanced design material in their states. The association also is developing an online training platform and will beta test it with one or more affiliates before rolling out the program nationally. The anticipated release is mid-summer.
