Stormwater Pit Installation – Lakelands
How our team drained a low point that held water after rain, with a 300 mm stormwater pit tied into the existing stormwater line.
Background
A Lakelands homeowner called us about a section of their yard that held water every time it rained. The rest of the property drained away, but this one low point stayed wet for days afterwards. They wanted it dealt with before the soft ground spread any further or started killing off what was planted around it.
Our drainage system installation work runs from full systems across a property down to a single collection point, and this job sat at the smaller end. One 300 mm x 300 mm stormwater pit, also called a surface water sump, connected into the stormwater line already running past the area.
Inspection and Diagnosis
We assessed the fall across the yard before quoting. Fall is the slope that decides where water runs, and on this property everything ran towards the one low point and stopped there, because nothing had been put in to take it away.
Water sitting on the surface after rain is a stormwater problem rather than a subsoil drainage one. Subsoil drainage collects water from under the soil through buried perforated pipe. Stormwater drainage collects it off the surface through grates and channels. Getting that distinction right is what decides whether a property needs a trench and a full run of pipe or a single collection point, and it’s the difference between a few hundred dollars and a few thousand.
The existing stormwater drain ran close enough to the low point to connect straight into it, which kept the excavation short.
The Installation: Step By Step
Six stages, all completed on site:
- Set the position: We marked the pit at the actual low point rather than the middle of the wet patch. Water finds the lowest ground, so a pit set even slightly high will let it pool alongside instead of running in.
- Excavate and set the pit to level: We dug out for the 300 mm x 300 mm pit and set it so the grate finishes flush with the surrounding ground, or a touch below in a grassed area, so surface water runs straight in, and a mower passes over without catching.
- Connected into the existing stormwater drain: We tied the outlet into the stormwater line running adjacent to the area, with fall on the connection so the pit empties rather than holding water between downpours.
- Fitted the galvanised steel grate: Galvanised steel is used here rather than plastic because it takes foot and mower traffic without flexing, and the zinc coating stands up to sitting in wet ground.
- Backfilled and compacted: We backfilled around the pit and compacted it properly. Loose backfill settles over the first few months and drops the grate below the surrounding level, which puts a lip around it and undoes the work.
- Tested the flow: We ran water into the pit and watched it clear through to the stormwater line before finishing up, then left the surface as we found it.
Result
The low point drains now instead of holding water, and the surface water leaving that part of the yard goes into the stormwater system it should have been going into all along. The lawn and plantings around it get a chance to recover.
The pit doubles as an access point. Anything that washes into it can be cleared from the surface rather than dug up, and lifting the grate once or twice a year to clear out what’s collected is all the upkeep it needs. Where water is still sitting elsewhere on a property, drainage maintenance across the whole system is the sensible next step
Water Pooling in Your Yard?
Water that sits after rain doesn’t stay a cosmetic problem. It kills lawn and plantings, softens the ground near foundations, and takes a section of yard out of use for weeks at a time. Our team can assess where the water is going and quote the fix in writing before anything gets dug.
Call us on 02 4006 8330 or book a service here. We service Lakelands, Newcastle and across the Lake Macquarie suburbs. Our drainage case studies cover the range of this work, from a single stormwater pit through to full subsoil systems.
