The TBMs use electricity. Each machine have a connected load of 8.3MW, with incoming voltage at 22kV. This voltage is transformed to lower levels at the machines to meet requirements.

Yes and we work in a three 8-hours shifts per day.

The system works on principle of efficient monitoring. River monitoring instruments will be installed at the upstream of Sg Ampang and Sg Klang and Sg Kerayong at the downstream. As this system has a storage capacity of 3 million cubic meters, the diversion and release will be regulated according to the river capacity downstream. The capacity constraint at Sg Kerayong is incorporated into the system. Flooding downstream is thus not possible.

Both pond at either end of the tunnel becomes government property and will be gazetted by the relevant government agency. The ponds will be secured with physical high-security fences to prevent unauthorized intrusion. Any form of public activities would not be feasible.
