Chennai: Be prepared for fluctuation in the pressure of water supplied by Che­nnai metro water (CMWSSB) if you are a resident of Tondiarpet, Royapuram, Thiru Vi Ka Nagar, Anna Nagar, Teynampet, Kodambakk­am and Adyar.

Hamstrung by the yawning gap between demand and supply this summer, CMWSSB has ‘reorganized’ water distribution in seven city zones. High-pressure water supply will be alternated (among the seven areas) on different days to avoid major disruption in supply, senior CMWSSB sources told DC.

However, existing supply will be maintained in added areas, viz Thiruvotriyur, Manali, Madhavaram, Ambattur, Valasarawakkam, Alandu, Perungudi and Shollinganallur areas, sources added admitting that they have pinned their hopes on Krishna water from Andhra Pradesh and the brief spells Chennai would receive during ensuing southwest monsoon season to meet the future demands. The existing 2.37tmcft in the four city reservoirs will last till mid July.

Meanwhile, TN water resources department has informed CMWSSB that AP has agreed to release Krishna water from the first week of June. Initially, 300 cusecs will be released and the discharge will be steadily increased as soon as the repair works at Ubbalamadugu get over, sources added.

Meanwhile, 234 borewells have been dug in the city to overcome the demand-supply mismatch and maintain the 830mld supply. CMWSSB has tapped 90mld from wells near Neyveli (Panrutti-Sethiathoppu) and 100mld and 70mld from Minjur and Nemmeli desalination plants respectively besides the usual supply from Chembarambakkam and Poondi reservoirs to overcome the summer shortage.
