Site- built septic tanks may still be permitted in some jurisdictions. Any of these materials can work fine for a septic tank provided the tank is properly installed.

Usually the tank is located close to the building for shorter waste line runs and because that's where there is often plenty of backfill to bury a septic tank during construction. Special tank designs are available for problem sites.

Septic Tank Retention Time if you just wanted to know our opinion about tank size as a function of effluent retention time, see EFFLUENT RETENTION TIME. Septic leach field or drainfield size and layout planning: see our article SEPTIC DRAINFIELD SIZE which sizes the field based on its percolation rate and our article SEPTIC SOIL & PERC TESTS which describes performing a perc test, with perhaps a look at SEPTIC BIOMATS to understand biomats that form below a drainfield and why a leach field in a wet area won't treat the effluent. Standard Leach Field Trench Specifications: conventional . The typical numbers you'll see for trench design in typical soils with acceptable percolation rate and excluding special and problem sites will look something like this: Leach line 4.

Most septic design authorities refer to a standard or generic two- foot wide trench. In the gravel in the trench, the perforated leach line pipe is placed on top of 6. Otherwise you may flood the system in wet weather. How Big Should the Leach Field Be?

The waste water is pumped uphill from my waste water tank. Is this hole supposed to be there? I replaced the elbow and hooked everything back up. I guess I am just looking to make sure that hole is supposed to be there or not. I didn't put a hole in the new elbow. I am hoping that this is correct.

Reply: Anon I'm not sure I have a clear understanding of your system and piping but I'm guessing that the . If that's the case, the opening is needed. But why it would be on the underside instead of on top is a point I don't get either. On the underside I'd think that wastewater would leak out of the vent opening during pumping.

Question: how could the septic inspector have measured distance to ground water? Deputy B said: We had a septic system inspection done and the company measured the ground water level at 4.

They indicated that the soil absorption system was at the proper level but the stone in the trenches was 5 feet 8 inches below grade. There is no engineering plan on file. The as- built document says that there are 1.

I'm having a hard time figuring out how they came up with the 5 feet 8 inches measurement. The only related information in the as- built plan indicates the elevation for the top of the foundation at 1.

I'm not sure how that information is used to determine the level of the stone in the trenches. Can you explain how that measurement was derived with the information in the as- built plan?

Assuming the measurements by the inspection company are accurate, is it possible to rectify the situation without putting in an entirely new system? Thanks in advance. Reply: Deputy. Like you I'm impressed that it sounds as if someone used X- ray vision or some other technique to determine the distance between the bottom of the septic system drainfield trenches and the seasonal high level of local ground water: at least that is what one should be measuring. It is possible that your inspector is reporting data that was on the original or as- filed septic system plans for your home, in which case Kudos to the inspector for taking the trouble to go dig up local septic system records. At the time that a septic system was originally designed and approved an engineer had test holes dug, percolation rates assessed, and the septic soakbed or drainfield plan would have (or should have) included an assertion that the design will meet your local requiements for the separation distance between bottom of the trenches and top of seasonal groundwater. Typically that's around 2. More in some areas.

Stone levels in trenches might also have been specified by the septic engineer. Really? However in my OPINIOIN it is misleading (to put it politely) to suggest that those data were actually visually or physically inspected at the time of your septic system inspection and test unless the inspector actually did so.
