New Security Measures

New Measures for Water Storage Tanks

Securing of tank covers by bolting/fastening was introduced in June 2011 and to be fully implemented by December 2011.

This involves the installation of a bracket onto the tank cover using SS304 38mm x 3mm thick flat bar. A base piece of equivalent material and M8 bolt is fastened onto the tank with 2.3mm thick 3M VHB tape, without drilling.  The bracket is then bolted onto the base plate with tapered round nut, which can only be opened with a hook wrench or C-tool.

Additional requirements include the use of high-security padlocks with non-duplicable keys.
