Obtaining Neighbour consents for stormwater pipe connection

[SunnyP]

Hi folks,

I am researching to build a minor dwelling before UP kicks in.

Unfortunately the main house does not have stormwater pipes as it was built in 1962.

The closest public stormwater pipe (150mm) available is the one across my neighbours (A and B) as you can see from the screenshot.

Actual public stormwater pipe is very close to the boundary between two neighbours (A and B) that I need to get consents from.

Here is my questions:
Q1. Of course the ground work has to be done in neighbour A's land. But what about neighbour B? Do workers(watercare?) normally have to go to B's land for groundworks? Or is it close enough to get the access via underground from neighbour A's land to the public stormwater pipe in neighbour B's land. Nevertheless I am going to get consents from both but I would like to give them the proper explaination what's going to happen.

Q2. When you visit your neighbour (one is pretty close but B neighbour, we never seen as different access), what do you do? do we need to bring something? Is there any tips to get consents successfully? Any tips are welcome guys.

Thanks for reading all!

can you not just hook into the existing sewerage pipe on your property? what are you doing now with your storm water? does it just go into the ground?

Q1 - depends, but I would say you need both. watercare might have access because the pipes are there but still its easier if owners aggree.

Q2 - depends on the neighbours, don't think think there is any tips just use common sense, be honest and open. some people can be funny about this sort of stuff, but doesn't sound like they would have any reason in this case, for what that's worth. let me know how you go.

Hi HattickNZ,

Thanks for your reply mate.

Dont think I can just hook into waste water pipe aye. At the moment, the pipes connected the gutter goes underground but have no idea how those end up.

Also I will let you know how things go

Screenshots dont work?

there is legal provisionsto make the neighbors give you access to a public drain

Can you syphon stormwater to the kerb?

Sit down with a council development engineer and they will talk you through this for your area

Thanks John,

THis forum doesnt allow me to put the full URL. Can you try this without quotation marks?

Cannot do that to kerb as it is uphill. I talked to an engineer and she gave me neighbour consents forms to fill up and attach them with building consent application.

I am trying to get this done first and talk to an archtect to draw plan & etc.

[John the builder]

you can syphon if the gutter is above the kerb?

you could talk to rear neigbour as well? which gives you two options (either side of boundary)

Thrusting can avoid open trenches

Talk to area engineer It is possible they don't want you in the manhole either. The other possibility is retention/soakage on site? or small pump to the road.

If you are on same title then why not hook into the house drainage?

[SunnyP]

The gutter of main house is higher than the level of kerb. However the gutter of minor dwelling is lower than the level of kerb.

(Again, main house doesnt have stormwater pipe as it was built in 1962. )

Yes as you can see from the link, there are two ways to connect to the public stomwater..

Option 1: The black line in the screentshot(link) is going through two neighbours.
Option 2. Another line can be connected through my next neighbour but that requires 3 consents as another neighbour is cross-leased property.

So that is why I am trying to get to Option1 as I need only two consents.

[John the builder]

The other option s to retain the stormwater on site and dissipate to soakage over time (talk to stormwater engineer Dave Kettle 09-4264909 is in your area) and/or a small pump to the main house drain. Might be cheaper than the hassle and cost of gravity feed to manhole

Thank you very much John for all your replies. I will give him a ring!

Hi Sunny,

I'm guessing your sleepout will be over the maximum m2 addition so you will need a stormwater solution, and the solution the council will want will be for you to tap into the manhole you have indicated. Soakage & detention solutions are messy and a hassle (especially long-term) versus simple discharge.

You will need the area surveyed. You will need a stormwater engineer to draught the fall of the pipe to the manhole. You will need the consent of both the other property owners. Property A will have a long open trench dug in it's back yard (good that you know them), property B will just have the fence area disturbed / dug up in order to connect the new line into the manhole. There are trees there too so they might be problematic. Thrusting is expensive and not appropriate for your objective as you have access. You get a private contractor (council approved) to all this and they liaise with watercare/council for any signoff. I have done all the different solutions (thrusting,detention, soakpits) and simple open trench connection is the easiest by far.

Stormwater

Hi Craig, I'm dealing with a similar issue, but looking to place 2 units on a rear section and have 2 options for stormwater - 1 into a watercourse (not council approved) in rear site or a public manhole on the other side, Both neighbours are not keen - obviously they don't want to see houses close to there property ! How can we proress if both neighbours don't allow access ?? Thanks Gareth

Does putting a storm water pipe through the neighbours section then limit the neighbours ability to build over the top of it?
If so - what neighbour in their right mind would let you do it?

It does potentially reduce their options in the future - I wouldn't be keen.
Down the boundary (or right beside it) is the best to keep options open.

[John the builder]

if the roles were reversed would you want approval?

Hi John,
Quite interested to know if the legal provision to make the neighbours give you access to a public drain really works and where can I find a reference to it.I checked this with the council and they said it is quite a process .Have you tried it in any of your projects.
We have a private connection with a neighbour who is hesitant to give us permission and to let the council to vest it as public .The council does not want any other stormwater mitigation as the property slopes away from the road and the private stormwater drain is just at the back of the property on the neighbours land.They want us to increase the diameter of the pipe.Would you know of any good stormwater engineer out west or central?Thanks
