Balwyn is about 2410 people per square kilometre. Standard installation, standard method, and a fault usually found inside the first hour. At about 84 metres, Balwyn is low and level, where water ingress at an outdoor point after heavy rain is the seasonal cause.
Balwyn sits 10 kilometres from the city. Older homes here frequently have shared neutrals from earlier work, and they cause faults that look random. Balwyn sits inside Boroondara, and council approval is not part of this work.
Balwyn is bracketed by Balwyn North and Canterbury, both of which we are in regularly, so scheduling here is rarely the hard part. The 2021 census figure for Balwyn was 13495 residents. The suburb covers about 5.6 square kilometres of Boroondara under postcode 3103.
Worth knowing before we arrive: === 19th century ===
Following the Foundation of Melbourne, Balwyn was part of Henry Elgar's Special Survey of 8 square miles (21 km2) in 1841, which was subdivided into small farms and grazing runs. Era predicts whether the board can isolate circuit by circuit. Day to day we are across Balwyn and the streets either side of it: Balwyn North, Canterbury, Deepdene and Kew. Same crew, same rates, same certificate at the end.
Balwyn is around 12976.6 kilometres north-west of our workshop in Boronia, close enough that the van is stocked for the job before it leaves. Something else that shows up in the housing here: The Outer Circle railway line, with a station at Deepdene, opened in 1891, was closed in 1893, re-opened in 1900 then finally closed to passenger traffic in 1927.
