Browse Forums General Discussion 1 Feb 18, 2017 6:57 pm Hi , im building a new home in Denham Court in the Willowdale estate. Im on a small cnr block and there is a storm water pit in the back left cnr where it meets the side street. Ive noticed that the level of the pit is atleast 3/4 to a meter below the level of the house. This is going to create a problem when i get around to lanscapping as i wish to level the land with the use of a retaining wall. My question is how can i go about the issue of the pit being at such a low height? Is it possible to raise it to the level of my planned turf? If so whom do i need to take on this work? Any help or advice is appreciated I said after the 1st build “ never again “ & now im on my 3rd Re: Stormwater pit in new estate 2Feb 18, 2017 8:10 pm You need to talk to the council (the drainage authority) who will be the owners of the pit.

Re: Stormwater pit in new estate 3Feb 18, 2017 11:10 pm By pit do you mean a hole with a steel grate on top or a round concrete lid thing? Do you have a drainage easement on your property? I doubt they'd raise it which means a retaining wall depending on the answer to the first question. Re: Stormwater pit in new estate 4Feb 19, 2017 9:51 am HiCD12Jd I am surprised you built up retaining levels without Stormwater (Retention/Detention) considerations first?

Very true and it is becoming a big problem that can only be addressed by regulations. But, these regulations are forcing huge costs on the average battlers when they can least afford it?

The environmental impact of falling water tables when creating large housing areas with accompanying harsh heat signatures on former oases is a rarely considered environmental concern that should be considered when detention systems are specified. Having excessive stormwater directed to ground water recharge points would be a low cost environmentally beneficial solution. 3in1 Supadiverta.

I doubt they'd raise it which means a retaining wall depending on the answer to the first question It is a hole in the ground with a steel grate on top, when i look into it there seems to be 4 walls, a base and x1 opening. It is a house and land package and i had no say on the level that the home was built on. Around the home its level where they have "cut n fill" only issue is the back cnr of the block has this and its much lower then the rest of the land if this makes sense. Sorry building is all new to me so my wording might be incorrect I said after the 1st build “ never again “ & now im on my 3rd Re: Stormwater pit in new estate 9Feb 23, 2017 9:30 pm StructuralBIMGuy HiCD12Jd I am surprised you built up retaining levels without Stormwater (Retention/Detention) considerations first?

Unfortunately the old stormwater systems can no longer cope with flash storms. the property is a house n land package and i had no say with regards tothe height of the slab... because its all new to me i didnt see this being an issue until i recently went on site to view the house I said after the 1st build “ never again “ & now im on my 3rd Re: Stormwater pit in new estate 10Feb 24, 2017 8:39 pm It's an open stormwater drain. Kinda sucks but that's where everyone else's runoff will go. Just be careful about trying to build anything around or near it as the effect could direct water where you don't want it to go, including into your neighbours. Hide it with some bushes (but not gardens as they'll be washed away). Maybe some low growth grevillea. They're pretty hardy. Hi All! I have engaged a plumber to re-do the stormwater drainage system on my property which is mid-70s and had blocked/cracked clay pipe drains. The works has… 0 18708 Thanks for that, the PVC pipe is still about 40cm below ground level and it sticks out of the sand with no end cap or anything on it just open pipe, is this the finished… 2 10464 Plumbers 'can be' plumbers, made all the worse by self certification which the building surveyor invariably accepts as proof of compliance!
