Experienced Plumbers for Drainage Services
When heavy rain hits the Hunter Valley, a poorly drained property quickly turns into a nightmare. Water pooling on your lawn is more than just a landscaping issue. If surface water or underground moisture is not properly diverted away from your home, it can cause severe structural damage.
Excess water pooling around your concrete slab or brickwork leads to rising damp, shifting foundations, and cracked walls. At On Time Plumbing, we do not just apply temporary fixes. We diagnose exactly how water is interacting with your property and install permanent, high capacity drainage systems that safely channel water away from your home.
Our Stormwater and Sub Soil Drainage Solutions
Every property handles water differently. Whether you are dealing with a flooded driveway after a storm or a retaining wall that is constantly weeping, our fully licensed plumbers provide the exact system required to keep your property dry.
Stormwater Drainage
When your roof gutters overflow or your driveway turns into a river, your surface drainage is failing. We design and install surface grates, stormwater pits, channel drains, and complete downpipe systems. These capture heavy rainfall immediately and direct it safely into the municipal stormwater network.
Sub Soil Drainage
If your backyard feels like a swamp days after it has rained, you have an underground moisture problem. We install highly effective French drains and slotted aggie pipes surrounded by blue metal gravel and geotextile fabric, intercepting subterranean water before it reaches your foundations.
Drainage Repairs and Clearing
Often an existing drainage system is simply blocked by heavy tree roots or crushed under the soil. We use advanced CCTV drain cameras to locate the exact break, allowing us to clear the blockage or replace the crushed section without unnecessary digging.
Retaining Wall & Slab Drainage
Constantly weeping retaining walls and damp slab edges need water intercepted before it ever reaches the structure. We design agricultural drainage behind walls and around slabs so moisture is captured and carried away rather than soaking in.

Frequently Asked Questions
Stormwater drainage handles the visible water that falls directly onto your roof, driveway, and paved areas during a downpour. Sub soil drainage manages the hidden, underground water that seeps through the earth and saturates your lawn or presses against your retaining walls.
Look out for water pooling on your lawn for hours after rain, damp patches on your interior walls, a constant musty smell underneath your house, or visible soil erosion around your garden beds and pathways.
We do not usually charge a call out fee on weekdays during business hours, but a call out fee does apply after hours and on weekends.
Yes. If your current pipes are blocked by debris or tree roots, we can clear them using high pressure water jetting. If a pipe is cracked, we can often repair it. We will always assess the condition of your existing system before recommending a brand new installation.
