KUALA LUMPUR, Dec 20 — Water treatment plants affected by Tenaga Nasional Bhd repair works are back to full capacity and will begin resupplying the Klang Valley on schedule, Syabas said today.

The utility recommended, however, that consumers continue to conserve their water stores until supply is completely restored.

"Relief water supply will be sent by water tankers to affected zones without water supply due to low levels of water in the service reservoirs.

"Consumers can request for relief water supply by sending SMS to 15300 by typing TANKER Name & Address,” it added in a statement.

The schedule appended to the statement is the same as previously disbursed, indicating that water supply interruptions in Zone 2 could remain until Christmas eve on Saturday.

TNB had shut down its main entry substation in Bukit Badong, Hulu Selangor for what it described as emergency repairs, which were initially scheduled for September but delayed at the request of water firms and the National Water Services Commission (SPAN).

The repaired had required three major water treatment facilities along Sungai Selangor to run at lowered capacity, affecting supply to nearly four million consumers in the Klang Valley.
