Re: Rising Storm Water Pit 5May 13, 2021 1:10 pm "But maybe you could just add a second lid up higher that allows water entry" Yes I'm going to have a lid on top of the riser but I don't see it's possible for the flood water to rise that high "sounds like op's garden may have been raised, before or after construction" Yes. the garden has been raised so that it's level. Originally, it slopes from the slab to the pit (600mm for 4.5m) "Is the pit a surcharge pit?" It looks like a surcharge pit with a grate on top. "If you raise it without a surcharge point your stormwater will flow upstream out of their surcharge pit flooding their property." I don't understand this part. Can you elaborate? The whole street is pretty much has the same issue. Most of my neighbours choose option 2. To help you easily imagine, the ground level (which is also the pit level) of all slots in the street is sloping. Let say my ground level (and pit level) is x, then the whole street looks like this: [x+50] [x+40] [x+30] [x+20] [x+10] [x (mine)] [x-10] [x-20] [x-30] [x-40] [x-50] Re: Rising Storm Water Pit 7Mar 01, 2023 1:09 pm 4re5 Hi, sorry to resurrect this old pots, but how you solved this issue. I have the same situation with the exception that my pit doesn't have a grate but concrete lid cover. Regards, doesn't sound like its the same type of drain, so its not entirely the same issue. Given it has a concrete cover on it, Its unlikely to be for overflow. should be ok to put a riser on it. Check with council. Or if this is access to your sewer inspection, you can just extend it without contacting council. In my old place I put a marker next to it and cover d it in mulch lol.

I checked and is not a overflow is just a inspection pit to where my neighbour has his LPD for the stormwater.
