Browse Forums Building A New House 1 Jun 30, 2014 10:11 am Hey All, I am currently in the process of developing a dwelling to the rear of my PPOR and have just discovered we have no storm water. My block slopes to the rear with about a fairly decent slope (roughly 5m from curb) I have spoken with Council who confirmed this and also my neighbor who actually showed me his storm water pipe running into the rear neighbors backyard!!!!!! I was still not 100% convinced though, I mean the land was subdivided around 70 years ago but given all the the sloping blocks surely there should have been storm water installed! So on the weekend I took to my backyard with a shovel and started to locate where all the pipes were running. After several holes I found myself in the easement where sure enough I found the end of the storm water pipes which were buried around 30cm under the soil and open which meant the water would pretty much run directly into my neighbors backyard! (same neigbor with a big block) The interesting thing though is the soil was not wet? The block is in Melbourne and we have had a fair whack of rain so i would have expected it to be very wet but it wasn't? I am not sure what to make of that? I put my hand into the pipe and it was compacted with soil but perhaps given the pipe is old ceramic then it would have leaked through the joins throughout. So anyway I have now been advised I will need a pump system engineered to push the water back up the hill to the only available "authorised" council storm water at the curb. I have not received an actual quote but I have been advised to expect anything from 15-30k!!! So before I do that I just wanted to throw it out there to see if anyone had any suggestions at all? Has anyone dealt with this? I did read someone had a similar issue and actually elevated the slab so the water could run downhill so no need for a pump. I unfortunately do not have this luxury due to the dwelling being at the rear and the size of the slope. Thanks in advance Re: New Development but no storm water. HELP! 2Jun 30, 2014 5:06 pm &0 Years ago with big gardens and small houses it was possible to get away with some questionable storm drainage practices. When more of the block gets covered there is a need to move to a more appropriate solution. Two options 1, Get an easement over the rear neighbours land and pay for the cost of laying a pipe and restoring his land. Laying a pipe through an existing garden won't be cheap. 2. Pump Solution. You will need some sort of detention storage as well as a pump as its normally not practical to pump the peak flows. It will be cheaper if your detention storage can be above ground tanks ( see this link for some more info: http://www.anewhouse.com.au/2014/06/on- ... n-storage/) The Harder You Try - the Luckier You Get !
