Helen said one element of the plan to have been confirmed was a new access road off Grant Avenue, which will be permanent and only a few metres away from her front door.
“Even after the works have been finished, which may be two years, maybe more, they admit there could be up to 40 trucks coming and going from the new access point.”
She said the “rumbling traffic and extra lorry loads” would be “horrible”.
UU said almost all of the affected area would be usable after the work is completed, with the park looking almost identical to the way it looks now, except for the access road.
The company said it looked at other sites nearby for the tank system, but there were limited options in terms of size and location.
Helen said: “I want clarity from Liverpool City Council and from United Utilities.
“What are you doing? When are you doing it? What’s the result going to be? And to be honest about that, it’s very upsetting.”
