Approval from Unitywater for driveway design over sewer

Hi Doug

I can confirm that the standard crossover will be fine with having a structural concrete path with concrete footings each
side of sewer to avoid any loading impact.

Any alteration to the Unitywater infrastructure like manhole lowering or connection moving etc needs to be applied
through the Unitywater Private works area.

Kind Regards

Hi Jarrod,

Hope you had a great Christmas and New Year. I am starting the year with a request for some advice. We have been
engaged to design a driveway for an existing vacant lot at 16 Myles St Tewantin. The verge profile is non compliant with
the footpath level approx. 400mm above the top of kerb. There is a sewer located in the verge that is only 1.3m deep. If
we were to construct a standard driveway profile across the verge then the cover over the sewer would be reduced to
540mm. We also looked at a non standard crossover (bridged crossover) that would improve the cover to 800mm which
we appreciate is still not complaint. Refer options drawing attached. Council have indicated that their preference is for
the driveway to be constructed to the standard profile so we need Unitywater approval for the reduced cover over the
sewer (540mm). Refer email trail below. Note that there is little opportunity to lower the sewer to improve the
situation. Can you please advise if Unitywater would accept the reduced cover in this location?

Thanks for your assistance.
