Somerville sits at the northern end of the Peninsula where the market gardens meet the suburbs. There is an older township core around the station and the shops, a large amount of estate housing built over the past few decades, and semi-rural blocks on the edges. Each of the three has a different drainage story. Peninsula Blocked Drains is a local referral service. We put you in touch with licensed local drain plumbers we work with who service Somerville.
Why Somerville drains block
In the older core, the pattern is the familiar one: clay sewer lines with aged joints, established street trees, and root mats that rebuild every year after clearing. If your house predates the estates and your drain blocks on a cycle, roots are the first suspect.
In the estates, pipework is modern PVC and roots are rarely the issue. What blocks these lines is what goes into them. Wet wipes, fat, nappies and food scraps account for most call-outs, and shallow stormwater pipes take years to stop coughing up builders' sand and mortar from the construction phase.
On the semi-rural edges, some properties run on-site wastewater systems rather than reticulated sewer. There the symptoms look identical from inside the house, but a full or failing tank is a pump-out job for a liquid waste contractor rather than a jetting job for a drain plumber.
What clearing a blocked drain involves
A CCTV drain camera settles quickly which of those three situations you are in. Jet blasting clears both root mats in clay and fat build-up in PVC, and recurring tree roots in drains in the older streets lead to a relining conversation.
A standard clear typically costs $150 to $400. Root clearing typically runs $250 to $600. A camera inspection runs $249 to $600, or $350 to $900 combined with jetting. Relining typically costs $3,000 to $8,000 or more.
Frequently asked questions
My house is on a septic system. Can you still help?
Yes. A plumber clears the house drains and tells you whether the problem is the line or the tank. A full tank needs a pump-out, which is a separate contractor and a separate cost.
Are estate homes really less likely to have root problems?
Generally yes. PVC lines with sealed joints give roots far less to work with. They still block, just for different reasons.
Why is sand still coming out of my stormwater after years?
Construction sand works its way through estate drainage for a long time, especially where pits were left unsealed during the build. Jetting clears what has settled in the flat runs.
