In terms of Section 17(5) of CGST Act, ITC is restricted in case of following:
Section 17 (5) (c) - Works contract services when supplied for construction of an immovable property (other than plant and machinery) except where it is an input service for further supply of works contract service;
(d) goods or services or both received by a taxable person for construction of an immovable property (other than plant or machinery) on his own account including when such goods or services or both are used in the course or furtherance of business.
Explanation.''For the purposes of clauses (c) and (d), the expression 'construction' includes re-construction, renovation, additions or alterations or repairs, to the extent of capitalisation, to the said immovable property;
Therefore, in the present case if construction services are being provided by municipalities (which is unlikely), then ITC can be taken.
ITC can also be taken if the nature of work is like renovation, repairs if not capitalised.
From the nature of output services mentioned, it appears that credit is not eligible.
Hope this would be helpful in analyzing the issue further.
