Browse Forums General Discussion Re: Large Pit in Front Yard - Not sure what this is 3Oct 31, 2021 4:57 pm aussieta i am guessing it is a stormwater retention pit too small for septic Thanks for that, I'll try to test that out sometime by hosing water into a down-pipe to see whether it discharges into the pit. I forgot to mention it is only a 2-bedroom house so any septic tank could be on the smaller side. I've also seen mention that sometimes separate black-water and grey-water septic tanks are used, which could allow a smaller size but I have no idea if separate tanks were used back in the 1950's. Re: Large Pit in Front Yard - Not sure what this is 5Nov 02, 2021 7:26 pm I've seen something similar in the past that was an old sediment trap for stormwater. Water flows out of one pipe, fills up the trap with the water/sediment mix with the sediment falling to the bottom and the water only flowing out of the other to the street gutter.

The pit dimensions are roughly 1m x 0.6m x 1m deep. The two t-shaped pipes are hollow at both ends. One goes uphill towards the side of the house, the other goes towards the street-frontage. I'm guessing it may be an old septic tank, but I'm not too sure. House was built in 1950-1960, in the Warringah Council area. The nearest stormwater pipe would be 8m+ away, so I'm assuming it has nothing to do with stormwater. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Don’t know if you got the answer you were after. I have a small plastic version in the front yard that was installed to try move on some of the winter/spring excess rain the turns my front yard into a swamp each year. They catch the sediment and allow the water to flow through minimising potential blockage. The one I have was poorly placed and to try save the house I’m looking at doing a ‘French drain around the perimeter of the house’ If you find you have poor drainage too maybe check it out they seem effective (if put in the right spot) there should be ss cable so you can pull up bore pump for service 1 3356 Hi all, Need some ideas for my front yard.
