Mangaluru: The water storage level at Thumbe dam, the primary source of drinking water for the city, has remained stable despite a slight dip observed over the past 15 days. Authorities have assured that there is currently no shortage of drinking water within the Mangaluru City Corporation (MCC) limits.
The dam, which has a total storage capacity of 6 metres, is presently holding 5.5 metres of water. Officials noted that this level is adequate to meet the city’s immediate requirements and does not pose any cause for concern.
Comparison with previous years
A comparison with past years indicates that the current water level is relatively stable. On the same date last year, the storage stood at 5.25 metres, while it was 4.91 metres in 2024. In 2023, the level was higher at 5.98 metres.
Earlier records show that the dam was at full capacity of 6 metres in both 2022 and 2021. In contrast, lower levels were recorded in 2020 at 4.90 metres and in 2019 at 5.11 metres. This year’s storage is therefore within a comfortable range when viewed against historical data.
Daily supply and treatment infrastructure
As per official data, approximately 160 million litres per day (MLD) of water is pumped from Thumbe dam to meet the needs of Mangaluru’s residents. The water undergoes treatment at two purification plants before distribution across the city.
One of the treatment plants, built in 2009, has a capacity of 80 MLD, while the older facility, constructed in 1983, can handle 81.07 MLD. Together, these plants ensure a steady and safe water supply to households and commercial establishments.
To further strengthen the supply system, a new 20 MLD water treatment plant is currently under construction at Ramalkatte near the dam. Once operational, it will enhance the overall water availability.
New plant to boost supply
Of the additional 20 MLD capacity being created, 10 MLD will be allocated to rural areas, while the remaining 10 MLD will be added to the city’s supply. This will increase the total availability of treated water to approximately 170 MLD.
Officials believe that this expansion will not only improve distribution efficiency but also provide a buffer during periods of reduced rainfall or increased demand.
Rural dams also adequately filled
Recent rainfall in surrounding rural areas has contributed to improved water levels in other key reservoirs. The Shambhoor AMR dam is currently at its full capacity of 18 metres, while Saralikatte dam holds 4 metres of water.
Similarly, Jakribettu dam has recorded a storage level of 3 metres, and Harekala dam stands at 1.9 metres. These reservoirs play a crucial role in supplementing the city’s water supply, especially during peak summer months.
No immediate concern, says MCC
MCC Commissioner Ravichandra Nayak stated that the existing storage at Thumbe dam is sufficient to meet the city’s drinking water needs for the next 30 days. However, with additional pumping from the Harekala dam, the supply can be extended up to 110 days.
As a precautionary measure, the corporation has set up a control room to address any potential issues. Residents can reach out via helpline numbers 0824-2220306 or 0824-2220303 in case of water-related concerns.
Conclusion
While the slight dip in water levels had raised concerns earlier, the current situation remains under control with adequate reserves and supplementary sources in place. With infrastructure improvements underway and sufficient storage available, Mangaluru is well-positioned to avoid any immediate drinking water crisis.
