Re: Should Agi pipe be connected to Stormwater or frontyard 5Apr 30, 2022 7:46 pm re: connect and agi pipe directly to the stormwater Hi, l was wondering if someone could help with the issue we have. our front yard is pretty much clay. We landscaped it ourselves 2 years ago with trees and a stone yard. We planted 3 feature trees in the center but 1 died and 2 we repotted to save em because of the water build up in the clay. The issue is the water doesn't drain quickly enough during heavy rains. We did treat the top surface with gypsum when we did the landscaping 2 years ago but the but clay hasn't broken up. So this easter we dug a larger hole, with a trench at the front and a slight slope towards the trench. l placed an agi pipe thats in a U shape, at the base of the trench facing up. My idea was to use this to pump out any excess water once in a while in winter and water the trees in summer. But we severely underestimated how much water would accumulate in a single day. It took 2 mins per pet to drain with a pump after 1 nights constant rain. We spoke someone at a nursery who suggested that the we should have laid the agi pipe horizontally and straight into the storm water pipe so the water gets flushed out right away without accumulating which makes sense. That's what we were planning on doing and upon research l came across this post. So do we need a silt trap for the purpose of keep our 3 trees well drained when it rains? What would happen if we didn't have a silt trap? both short and long term. your advice would be greatly apricated.

To reduce water logging in that area you need to lay agg pipe on the perimeter of such area, ensuring its level is below 300 mm or whatever you managed to dig. What you did is created a pool. Unless you have an automated system to drain excess of water you need to establish at least a passive drain, say towards an onto the walkway or any other lower surface. The passive drain would be a 300x300 trench filled progressively with 20,10, 5 mm blue steel or reagg, and potentially wrapped in geofabric. One side of it is connected to your pit (which might need to be raised to ensure an appropriate fall) and the other is to walkway or any lower surface. I did this on a hilly area with surprise-surprise hydrophobic soil - worked well. Before i did it a few trees died due to waterlogging. Another option would be to mix clay with soil on a 3x3m area at a depth of 100 mm (should be easy) and create a box / raised garden bed sort of thing for the tree. It'll allow the tree to get established, but the raised bed, when it rots away will become a hill. I would not make such bed greater than 200mm above the ground though. It's only my opinion. 3 6547 Plumbers 'can be' plumbers, made all the worse by self certification which the building surveyor invariably accepts as proof of compliance!
