How to open the septic tank.
Septic tank cleanout or cover location, access, opening procedures. We describe some things to check before opening the septic tank, such as subsidence, evidence of recent work, or unsafe septic tank covers.
Then we illustrate how the septic tank cover or access port cover is removed. We explain why the best way to clean a septic tank is to pump out through a central manhole-sized cover, not an 8" cleanout port and not through the inlet or outlet baffle.

A Photographic Guide to Pumping a Septic Tank
How to remove a septic tank cover
Which septic tank opening should be used for pumping out the septic tank? Why?
This septic tank pumpout article series provides a step by step, photo-illustrated guide to opening, pumping, and inspecting septic tanks,
how a conventional septic tank is
located, opened, pumped out, cleaned, and inspected.
This guideline is intended for septic pumping tank truck
operators and as general information for homeowners or septic service companies concerned with septic system care.
Subsidence (depressions or low areas in the soil) at the septic tank location - may risk dangerous, potentially fatal collapse
Evidence of recent work which may need to be investigated to understand the condition of the septic system
Evidence of backup or effluent breakout at the surface in the septic tank area
Septic Tank Cover Safety: here a round tank cover was found over a collapsing home-made collection of concrete blocks
which had been stacked by the owner to form a septic tank access well.
There was a dangerous collapse risk forming a fatal hazard
because the masonry blocks were askew and loose, and because the tank opening into was larger
than the cover.
We covered the area with plywood, roped it off, and told the occupants and owner
of this condition immediately orally and also in writing.
Procedure for Opening the Septic Tank Pumping Access Port
The septic tank should be cleaned from a cleanout port - usually located in the center of the tank.
Pumping the septic
tank through a small access opening such as over the intake or outlet baffle does not provide enough space to adequately reach and
remove sludge from the septic tank bottom, and it risks future clogging of the tank inlet or outlet by incompletely-removed
In this example we knew from prior work, the measurements to the exact location of the septic tank cleanout cover.
The photo shows the septic tank cleanout port which we found and excavated to prepare for opening the septic tank.
The cover is about to be removed using a wrecking bar.
Note that we excavated far enough back from the tank opening itself that when we remove the cover we won't have a lot
of dirt falling into the septic tank.

cannot find the manhole cover of the septic tank
(Aug 8, 2014) vicki levin said:
We've found the cesspool concrete lid (about 12 foot diameter) but after digging a 2 foot circumference, we cannot find the manhole cover in order to have an inspection. Help? My guy is getting frustrated with digging!
IF it's actually a cesspool, not a septic tank, and it's round, usually the access lid would be in the center.
Question: how do i remove septic tank lid that is stuck
(Oct 5, 2014) Anonymous said:
how do i remove septic tank lid that is stuck down 1 inch below surface of tank.
WATCH OUT: if indeed the septic tank cover, lid or access opening has partly caved into or sunken into the tank then the situation is very dangerous - an unsafe cover means someone could fall into the tank - which is usually quickly fatal.
Keep people away from the septic tank area until you've had the tank inspected and opened for further inspection by an expert.
Actually if the hooks or handles intended to permit septic tank lid removal have broken away or were omitted, removing the lid may require using a pry bar or wrecking bar, even a small portable winch (not ususally) or other equipment depending on the tank material and condition.

Quoting an Amazon reviewer's comment, with which we agree--DF:This book is informative as far as it goes and might be most useful for someone with an older system. But it was written in the early 1980s. A lot has changed since then. In particular, the book doesn't cover any of the newer systems that are used more and more nowadays in some parts of the country -- sand mounds, aeration systems, lagoons, etc.
