What is the impact of AIDAP 2024 on water drawdowns?

Question

Accepted Answer

AIDAP 2024 Significantly Reduces Daily Water Drawdowns from Air Itam Dam

The Air Itam Dam Action Plan 2024 (AIDAP 2024) has substantially decreased the daily raw water extraction from the Air Itam Dam, ensuring that current water supply services remain normal despite the dam's reduced effective capacity. Since the plan's implementation on February 5, daily drawdowns have been lowered to 11 million litres per day (MLD). This contrasts sharply with the 44 MLD drawn on typical non-dry weather days and even the 22 MLD managed during previous dry weather controls.
Reduced Drawdowns Maintain Dam Reserves

Under AIDAP 2024, the daily volume of raw water taken from the Air Itam Dam has been curtailed to 11 MLD. This measure is a significant departure from historical practices, where 44 MLD was the norm for non-dry periods. Even during periods of controlled dry weather, drawdowns previously stood at 22 MLD. The stringent reduction to 11 MLD under the new action plan directly contributes to conserving the dam's remaining reserves.
Minimal Impact on Dam Capacity

The implementation of AIDAP 2024 has had a minimal effect on the dam's effective capacity. Since the plan began on February 5, the capacity has only decreased by 2.5 per cent, moving from 32.8 per cent to the current 30.3 per cent. This controlled drawdown rate has helped to preserve the water levels, preventing a more drastic decline that could otherwise occur under normal usage patterns.
Continued Water Supply Despite Lowered Capacity

Despite the Air Itam Dam's effective capacity standing at 30.3 per cent, water supply services in the Air Itam area are currently unaffected. The Penang Water Supply Corporation (PBAPP) is compensating for the reduced drawdowns from the dam by pumping 33 MLD from the Sungai Dua Water Treatment Plant. This supplementary supply ensures that the needs of consumers in the Air Itam service area are met without interruption.
