Stormwater pit installation
Collection pits positioned as part of a planned rainwater drainage system.

Runoff pooling outside or rainwater backing up? Get practical advice on stormwater pits, drainage pipes and an installation suited to your property.
When rainwater collects near a building, spills from a downpipe connection or sits across a path, the drainage system needs a closer look. The cause may be a blockage, a damaged pipe or a layout that no longer suits the site.
Jetty Plumbing installs stormwater pits and drains, investigates existing systems and helps plan drainage improvements around Coffs Harbour. We look at where water comes from, how it is collected and where the system takes it.
Tell us what happens during rain and whether the issue began after building or landscaping work. Photos taken from a safe location can help us understand the problem before a site visit.
Clear scope, practical planning and local plumbing experience.
Collection pits positioned as part of a planned rainwater drainage system.
New or replacement stormwater pipework with the route and connections explained.
Checks for recurring overflow, pooling and problems at accessible connections.
Investigation of leaves, silt, roots and other obstructions in rainwater lines.
Review how gutters and downpipes connect with the underground drainage.
Discuss access points, surface debris and recurring issues that need attention.

A useful drainage plan starts with the whole site. Roof water, paved areas, garden beds and existing levels all influence where runoff travels. Adding a pit without checking the connected pipework may leave the underlying problem in place.
We assess the proposed collection points, pipe route, access and connection options. The work may involve a new pit, replacement pipework or changes to part of the existing system. We explain the proposed approach before installation.
If underground access is needed, our plumbing excavation service can form part of the job. Broader site issues may also need drainage solutions beyond one drain.
Discuss a drainage installationLeaves and soil can collect at grates and within rainwater drainage lines. A visible surface blockage may be only one part of the issue, especially when water repeatedly backs up after rain.
We can discuss inspection, clearing and damaged sections of the system. Tell us which areas overflow, whether the problem occurs in light rain or only during a downpour, and any previous work on the line.
Stormwater drainage is separate from the sewer. Wastewater backing up needs a sewer assessment. Overflow from roof edges may also involve gutters or downpipe repairs.

It collects rainwater from roofs and other surfaces and carries it through the property’s drainage system. Pits, grates, downpipes and underground pipes can all form part of that system.
A blocked or damaged pipe, an unsuitable collection point or site levels can contribute. Changes to paving or landscaping can also affect runoff. A site assessment helps identify which factors need attention.
Yes. We can discuss new collection pits and pipework as well as changes to an existing system. The layout, connections, access and site conditions determine the work required.
Not necessarily. A pit still needs an appropriate connected drainage route. We assess collection points, pipework and the wider site rather than assume an extra pit alone will fix recurring pooling.
They are separate systems. Stormwater handles rainwater, while the sewer carries wastewater. Tell us where the water appears and whether it happens during rain so we can discuss the right assessment.
We can investigate blocked stormwater drains and discuss a suitable clearing method. Access, the obstruction and the condition of the pipe influence whether clearing or repair is required.
Send the site address, a description of the problem and photos of the affected areas. Safe photos or video during rain can help show the flow. Existing plans and details of recent building work are also useful.
