Browse Forums Building A New House 1 Jun 03, 2012 9:41 am I was hoping garner the knowledgeable people on the forum my help me with this question. When we built on a suburban block stormwater runnoff was simply a matter of having the basix tank connected to the stormwater/nutrient pit already provided. But now we are building on acreage we were wondering what most people do. Do you just direct the overflow downhill? Do you soak it to a gravel pit? We just have had a quote from one builder to install 20 lineal meters of tunnel trenching for overflow. I am still trying to find out what this is for.

Re: stormwater runoff on acreage 2Jun 03, 2012 10:02 am If you are building on acreage you want to avoid concentrating the run off so distributing the flow to a trench filled with gravel is a good way to go. I am assuming the tunnel trench is that with a large slotted pipe running through it. The Harder You Try - the Luckier You Get !

Re: stormwater runoff on acreage 4Jun 03, 2012 4:18 pm Call the local council and ask if they have any requirements, they will be more than happy to help if you ask them nicely.

Re: stormwater runoff on acreage 6Jun 15, 2012 12:55 pm Hi everyone thanks for you help on this. As people have pointed I just found out that it is for water dispersal that is for the reqt of council on acreages. It's interesting that the builder has done this as we have a small creek flowing thru our property approximately 30m away. I'd have thought it would be nicer just to send the water run off in a drain down to the creek? Maybe this isn't allowed for some reason? Now a call to council...

Your house probably doesn't seem much but a few km downstream and there can be many houses discharging to lots of small creeks. It all adds up! The Harder You Try - the Luckier You Get !
