Rockdale is the administrative heart of Bayside, built around the station and the Princes Highway. Older houses and semis fill the side streets, while apartment blocks have steadily replaced shopfronts and cottages along the highway corridor. Some of the suburb sits on low, flat ground towards Botany Bay, which matters when it rains. St George Blocked Drains is a local referral service. We connect Rockdale homes and businesses with licensed local drain plumbers we work with.
Why Rockdale drains block
Flat ground is hard on drains. Pipes laid with only a gentle fall carry waste and stormwater slowly, so sediment, grease and debris settle in the low points instead of washing through. On the lower streets, stormwater systems can struggle to shed water in a heavy downpour, and blocked pits or silted pipes make that worse.
The older homes away from the highway often still have clay sewer lines. Joints loosen with age and ground movement, and roots from backyard trees and street plantings work their way in.
The newer apartment buildings along the Princes Highway bring a different problem. Shared stacks and sewer lines collect wipes and kitchen grease from many households, and ground floor units are usually the first to see the overflow.
What clearing a blocked drain involves
The licensed drain plumbers we work with match the method to the cause. A CCTV drain camera identifies the blockage and any fall problems in the pipe. Jet blasting flushes sediment and grease out of flat runs and cuts roots out of old clay lines. For yards that pool after rain, a blocked stormwater clear and camera check shows whether the pipe is silted, broken or simply undersized.
A standard clear typically costs $150 to $400. A CCTV inspection runs $249 to $600, and a camera and jetting job $350 to $900. Relining a root-broken pipe typically costs $3,000 to $8,000 or more. Prices are quoted before work starts.
Frequently asked questions
Water sits in my backyard after rain. Is that a drain problem?
Often it is. On Rockdale's flatter blocks, a silted or blocked stormwater line shows up as pooling and soggy lawn. Jetting and a camera run usually find the cause.
Who looks after the stormwater pit in my street?
Street pits and council drainage are Bayside Council's responsibility. Everything from your gutters and downpipes to the kerb or council connection is yours.
Our unit block's ground floor drain keeps backing up. Why?
The ground floor sits lowest on a shared line, so any blockage further down shows up there first. The fix is in the common line, which is usually a strata matter.
