URGENT privy question

[American]

Looks like it has pipes leading to it like a cistern. You need a spring steel probe.

If your site is over a hundred years old, than that could very well be a cistern.
It would have been of no use when they got a plumbed water supply and most were fill with garbage.
I've dug a few and some were a bust but others were great.
Take a bar and shovel and do some excavating...

I still gotta finish mine & I'm hoping it's Great like you said? If not I know of 2 other Cisterns & a Well but hard to get my digging buddy to dig those, he only wants to dig Privy's.

I've come across one in my time, over 30 years ago. It looked a lot like your 2nd and 3rd photos. Also filled with period toss outs at the h2o entrance. It connected with a well to do old colonial house in a developed part of a small town. One of the toss-aways was a porcelain mantle clock case, c. 1920 that was intact but without its works. I happened to meet a descendant and gave it to her family. They actually restored it to working condition. Everyone was a winner. I hope you find a few bottles. The few I came across were smashed...
