septic system & onsite wastewater treatment & disposal regulations and regulators: Guide to agencies regulating sewage treatment systems for the U.S., Canada, the U.K. and other regulatory jurisdictions & agencies.
Contamination of groundwater from onsite disposal of septic tank effluent is an increasing concern. In this study, HYDRUS-2D sim- ulated the impact of clustered disposal systems on NO3 2 and fecal coliforms in groundwater in a rural community near Christchurch, New Zealand. The model included ...
That septic tank or cesspool accidents and an occasional loss are not a new hazard should come as no surprise, as noted in our copy of a 1962 septic tank report (left) in Melbourne's The Age, 27 June, 1962. The boy who fell into the septic tank had been jumping on top of the co...
Estimation of septic tank setback distances based on transport of E. coli and F-RNA phages Setback distances between septic tank systems and the shorelines of Lake Okareka, New Zealand were determined from model simulations for a worst-case scena... Liping,Pang,and,... - 《Environment Interna...
The purpose of the law is to eliminate sub-standard or polluting septic systems. A sub-standard septic system is one that has no treatment (secondary treatment) following the septic tank or has a secondary treatment system that has failed. These sub-standard septic systems pose an environmental...
Proper maintenance means more than pumping out your tank.Systems can be camera inspected to ensure all components are in good working order, and can be cleaned or repaired as needed. The drainfield must also remain as undisturbed as possible. Protect it from vehicles, heavy equipment,...
Setback distances between septic tank systems and the shorelines of Lake Okareka, New Zealand were determined from model simulations for a worst-case scenario, using the highest hydraulic conductivity and gradient measured in the field, removal rates of the microbial indicators ( counts/100 ml) ...
Setback distances between septic tank systems and the shorelines of Lake Okareka, New Zealand were determined from model simulations for a worst-case scenario, using the highest hydraulic conductivity and gradient measured in the field, removal rates of the microbial indicators (Escherichia coli and ...
an experienced septic service company in New Zealand. In New Zealand septic tank sizes range from 2000-6000 liters (500 gallons to 1,500 gallons U.S.) with the average being 3100 liters (about 800 U.S. gallons and below the minimum septic tank size permitted in most U.S. jurisdictions...
The effects of septic tank effluent on groundwater quality were monitored for 18 months near 2 disposal systems: a 5.5 m deep boulder pit in an unconfined aquifer, and an 18 m deep injection well in a confined aquifer, both in the Canterbury Plains, New Zealand. Partial sealing of the ...
