As part of the effort to solve the Mary Hill water problem, it is -
proposed that an extra 150 mm PRV be installed in the Lion’s Park Fressure
Reducing Station for the following reasons: .

‘Le To reduce restriction and thereby providing better flow.

To pravide a more efficient operation of the Pressure
Reducing Station during low flows.

To provide a stand-by flow route in the event of a fault
in the sole PRV leading to a breakdown of water supply to
Downtown and Mary Hill.

Tt is also proposed that a pressure recorder be installed in the
Lion’s Park Pressure Reducing Station for the following reasons:

To monitor the pressure variations in the GVWD supply main
and the PRV output main.

To provide a better means of response to the operation of
the Penny Place booster pump controls.

To provide the necessary data for the analysis of the water
supply network system of the southern part of the City.

SUMMARY :

To provide better pressure and flaw ta Mary Hill and to assist in
long term City water planning, the fallawing additions are proposed to the
Lion’ s Park Pressure Reducing Station :
