If anyone can give their 2c worth, it would be appreciated. Looking at a block in SE Brisbane Council and unable to get clear answers. Q1: How close to a sewer manhole can you build - considering there is ~1m fill surrounding it? Q2: Why would the development footprint hatch include the manhole and sewer easement? Q3: Any thoughts why there is a 1m wide sewer access easement when the sewerline doesn't run through it? See attached plan for site and possible house outline (proposing to move garage back towards manhole) Section for manhole in red box bottom right.
You probably need to do a dial before you dig search and also look at this page. Build over or near pipes - Queensland Urban Utilities My initial reaction is that you'd be building super close to the manhole and probably building over sewer. How big is the sewer pipe? Do you have to build a bridge to support your slab? I hope the block was cheap.
Thanks dontask for response. I haven't purchased as yet. Only enquiry. I understand the sewer through the site to be 150mm I believe a build over sewer application is required. Just confused as to reason the access "easement" exists at only 1m wide. Also aware of the UU link but mixed information about its actual application in this instance. Ie... How close can I build There is no soil test available as yet. I won't proceed until I have some clarity. Logan
That is generally as much space they require to dig up the yard if they need to install shoring, excavate & access their assets. It will also cost around $30k+ to encase the sewer if building over it.
Thanks ScottNoMates for heads up. So I'm clear, you need to encase the sewer line. This is a separate to manhole. Nb. I'm interested to build close to manhole but not over it. The garage would span over the sewer line. Just surprised the new sewer line wasn't laid through the "easement"
The manhole and pipe are part of the system and access to the manhole will be required regardless. If the sewer isn't in the easement where is it?
Looking over the pic, its not so bad. You will need to build a bridge over the sewer pipe before you can pour your slab over it. 30k is waaay overkill - should be between 1-2k per linear meter. If your garage slab is 6m you could budget 12k - 15k and it would be ok.
The easement is for access to the manhole, the sewer sits in an undocumented easement, nonetheless still an easement.
Easements are sometimes created, and the process for retiring an easement doesn't always mandate that docs with easement showing be modified. So the existence of a pipe without easement and easement without pipe suggest that something is wrong. Otherwise it is a nightmare with an actual pipe AND an easement with no pipe. Be very cautious until you know more
@Logan4120 your states water and waste authority will have legislation to cover all its assets. in NSW its found here View - NSW legislation this saves preparing millions of plans, documents and notations on titles. The relevant authorities assets are covered under the legislation. in addition to the sewer infrastructure it is quite possible a specific easement for access has also been created. but it's a bit hard to conclude anything from a snapshot of a plan of unknown origin. you will need to also review the deposited plan and title documents. @dontask has linked a document that should cover a few of your questions
Q1 - The sewer manhole needs to be open to the sky. From memory, you need to allow a 3m x 2m area around this. There should be a rectangular easement over the sewer which shows this area. You won't be able to build within this. You can build up to this area but the closer to the sewer you build, the more expensive the foundations will be. Q2 - I'd say the person who drew the plan was lazy and didn't think about the sewer manhole when they prepared the building envelope. Q3 - The 1m wide easement isn't over a sewer pipe. It provides access to the manhole for maintenance. You can't build over this.
