NMMC looks for al­ter­na­tive wa­ter source

Acute short­age of wa­ter has led to Navi Mum­bai which usu­ally re­ceived 430 mld of wa­ter ev­ery day from Morbe dam, now re­ceiv­ing only 300 mld of wa­ter.

On the other hand, there is no pos­si­bil­ity of ei­ther the height of Morbe dam be­ing in­creased or its depth. This has led to NMMC work­ing on a plan to look for al­ter­na­tive source of wa­ter from Patal­ganga river. The plan pro­poses to di­vert wa­ter from the river to Morbe dam which will en­sure enough stock of wa­ter in Morbe dam.

Ac­cord­ing to mu­nic­i­pal com­mis­sioner Di­nesh Waghmare, “As per our plan, em­bank­ment of Patal­ganga will be un­der­taken. NMMC plans to only use the wa­ter that ac­cu­mu­lates in rains for di­ver­sion to Morbe dam.”

He added, “This plan that will cost Rs 450 crore will help take care of the in­creased de­mand in the city. We will seek per­mis­sion from the state govern­ment’s var­i­ous de­part­ments.”

Navi Mum­bai pri­mar­ily sources it wa­ter sup­ply from NMMC-owned Morbe dam, that is lo­cated near Kha­la­pur in Raigad district at the Dhavri river which orig­i­nates from Patal­ganga river. The height of dam is 88 me­tres and its to­tal stor­age ca­pac­ity stands at 190.89 mil­lion cu­bic me­ters (MCM).

Since there was below av­er­age rain­fall in the Morbe dam catch­ment area, Navi Mum­bai is fac­ing an un­prece­dented wa­ter short­age. If the present sta­tus of wa­ter sup­ply is main­tained, Morbe dam will have lit­tle stock of wa­ter left by June.

Rais­ing the height of the dam or in­creas­ing its depth is hence not go­ing to make much of a dif­fer­ence. Hence stop­ping the flow of wa­ter in Patal­gange and di­vert­ing it to Morbe has been pro­posed. It will en­sure that even af­ter the rains, the dam will be full in Septem­ber. It will then en­sure that the city gets ad­e­quate wa­ter sup­ply through­out the year.

As com­pared to Morbe dam, the catch­ment area of Patal­ganga is more.

NMMC ex­ec­u­tive en­gi­neer (Morbe) Jaswant Mistry said, “We are plan­ning to col­lect wa­ter dur­ing mon­soon at Patal­ganga by em­bank­ing the river as has been done in Kol­ha­pur and sup­ply it to Morbe dam.”
