Neighbourhood war breaks out over retaining wall

Our third year of constant rain on the east coast of Australia is starting to take its toll in ways we would never have imagined.

In the western suburbs of Sydney, a neighbourhood war has broken out in Edensor Park.

On one side is Connie, who said: "I have to protect my property."

And on the other is Valentina, who said: "She is sending her water onto ours and flooding our property."

The two feuding neighbours have been filming each other during every downpour.

"It is surface water from the sky, not stormwater and I can't control it," Connie said.

The water from Connie's place runs down onto Valentina's home, which sits lower and, at times, she said, "it floods our home".

So recently, she built a brick retaining wall to hold back the deluge but when the tradies turned up, things turned ugly.

"She thinks our house is supposed to collect all of her rainwater," Valentina said.

"The council policy says the water flow must not be obstructed by kerbing, fencing, retaining walls,'' Connie said.

So during construction of "the great wall" of Edensor Park, the iPhone videos were running hot.

On one side, Connie and her husband are trying to stop the construction, on the other Valentina and her parents are shouting to stop.

The stoush was posted online and has generated more than seven million views and there's more to come.

"I won't give up, the police can arrest me,'' Connie said.

"But I have to protect my land."
