Subject: Government Information (Public Access) request - Stormwater drainage for Granny flat

Dear Blacktown City Council,

I am looking to construct a second dwelling on my lot in Seven Hills through CDC approval process. The land slops to the rear and does not have a drainage easement.

Could you please advise the range of stormwater drainage options acceptable under CDC by the Blacktown LGA?

I am looking to use two rubble pits build in the property as a stormwater drainage for both main dwelling and granny flat. Is that allowed?

Look forward to you guidance.

Thanking you,
Kand

You need to have a stormwater system which drains by gravity to the street or easement. Pumps and charged lines are not permitted.

Subject: RE: Government Information (Public Access) request - Stormwater drainage for Granny flat

Dear Peter Duffy,

Thank you for your quick reply. Am i allowed to build a charged line to pump the stormwater to the street?

When I talked with a builder he says, they can do a charged line via CDC but not allowed via Council DA process. Is that allowed?

Yours sincerely,

Kand
