Hi everyone,
We’ve been doing some work in the back garden and have had to replace some of our storm water drainage pipes. We have no connection to the street and are on a pretty decent slope downwards.
So all the water runs to the back of our garden and ultimately into our neighbors yard (and they have no issues with it).
We were contemplating building a rubble pit but just simply don’t have the funds right now.
So I want to just take the pipe you see in the image attached and add a vertical pipe that sticks out of the ground so the water can dissipate across the garden (mainly the dirt area) you see in the corner of our garden. The pipe is standard 90mm.
is there a name for that type of pipe that sits above the ground for storm drainage? I would want it to have a grate or cover or something on top so no debris gets in.
cheers!
Hi @lindner00,
While your plan to add a vertical pipe with a grate or cover is practical for dispersing water and keeping debris out, it’s essential to approach this carefully.
First, I’d recommend consulting with a licensed drainage professional to determine whether this practice is acceptable and complies with local regulations. Even though your neighbours are currently okay with natural runoff—which lower-lying properties are generally required to accept—collecting water and then discharging it may increase the volume of water entering their yard. This could potentially cause issues, and if any damage were to occur as a result, you could be held liable.
Seeking professional guidance ensures that your solution is both effective and compliant. They may also offer alternative ideas, such as interim measures for managing stormwater until you're ready to invest in a rubble pit. It's always better to be cautious and avoid unintended consequences when dealing with water management.
If the drainage expert gives your plan the go-ahead, they'd likely use something like this Holman 90mm Storm ABS Finish Collar with Grate.
Please let me know if you have any questions.
Mitchell
