Please find attached prints of our amended drawings 12/52-1A & 12/52-2A which
include the following amendments. All other drawings remain unchanged.
1. The new outlet pipe and associated baffle has been lowered to reduce the
baffle’s effect on through-flow and the upstream hydraulic gradient. Note that in this
section of the network, calculations indicate that pipes do not run at capacity due to
their 20% grade. The major effect on the hydraulic gradient is in the next pit
downstream, where the existing outlet pipe’s grade is dramatically reduced.
2. A grated hinged manhole lid has been incorporated in the lid of the pit. This will
allow easy access for cleaning and maintenance. The condition of the pit will be
easy to observe through the grate. Calculations indicate that this pit will not
surcharge due to it’s depth and the grade of the outlet pipe. However, should such
an event ever occur (e.g. major blockage of the 650mm diameter pipe) then the
surcharge would be relieved through the grated manhole and continue down the
existing nominated overland flow path.
3. A 25mm diameter pipe has been included to drain the standing water in the
225mm diameter pipe after a storm event. A first-flush diverter has also been added
to the stormwater collection system.
With regard to other concerns in the Information Request dated August 6,2012,the
Body Corporate will formulate an updated maintenance schedule of the pipe network
and appurtenances which will be submitted to Council as part of this operatonal
works application. Of/H):! 02.-U

This schedule will include a weekly inspection of the modified pit and the first-flush diverter and cleaning out and general maintenance when necessary. An additional maintenance inspection will be carried out after each storm event. This will be in addition to the current maintenance schedule of the network generally which includes the gross pollutant traps installed in the distribution pit and the individual soakage pits. Please contact me if you require any further information.
