No water rationing

THERE will be no water rationing in Selangor as water levels at its dams have remained consistent.

Selangor Waters Management Authority (LUAS) acting director Nor Zamri Sondor assured residents that water would not be rationed due to the long hot spell brought about by the El Nino phenomenon.

He said cloud seeding operations and transfer of water from 19 alternate catchment ponds in the state to seven dams had proven to be a proactive move in stabilising water levels.

“Our past experience made us plan much earlier and we took measures to address the dry spell including cloud seeding and water transfer from catchment ponds Selangor’s river basin,” he said.

The Selangor river basin can supply up to 800 million litres of raw water a day.

The water level at all seven dams were high especially at Sungai Selangor and Sungai Tinggi dams, which provided nearly 60% of Selangor, Kuala Lumpur and Putrajaya’s water supply.

Nor Zamri added that the water level at most of the dams were sustained at above 70% and the submersible pumps were able to operate in an efficient manner.

“Our cloud seeding operations using hygroscophic seeding began early in 2015 where 410 cloud- seeding activities were carried out with RM5mil allocation. Knowing that 2016, could put a strain on the dams, we doubled our efforts with the transfer of water from alternate catchment ponds,” he said.

He said in 2016, Selangor allocated RM16mil for cloud seeding, transfer of water from alternate catchment ponds and other water operations.

“From January to April, we carried out 130 cloud seeding operations,” he added.

Hygroscopic seeding helps enhance rainfall using a fine spray of salt generated by pyrotechnic flares.

Concerns over Selangor’s water supply have been the foremost issue on people’s minds as northern parts of Perlis from Wang Kelian, Kaki Bukit, Titi Tinggi, Beseri and Abi as well as Johor in the south had begun water rationing.

Some residents who called up StarMetro on whether there would be water rationing in the state, want the Selangor government to keep them informed about the water supply situation given the hot season.

Selangor Environment Association president M. Varatharajoo praised LUAS for doing a good job in providing treated water.

He, however, advised the people to use water sparingly to complement the state’s efforts to conserve water at the dams.

Nor Zamri said the alternate catchment ponds were part of the Hybrid off River Augmentation System.

“Cloud seeding is done over some catchment areas and river basins to increase water supply. Selangor has enough water resources and water levels at the dams remain adequate. Water usage per capita is high at 235 litres a day.

“As such, we urge consumers to take measures to save water to ensure continuous supply,” he added.

As of April 18, the capacity of water reserves in most dams exceeded 70% - Batu Dam (72.39%), Semenyih Dam (71.12%), Langat Dam (73.38%), Klang Gates Dam (64.75%), Sg. Selangor Dam (67.35%), Tasik Subang Dam (87.93%) and Sg. Tinggi Dam (76.88%).
