In a release, ACB, said that Pawar was scheduled to come to their office in order to answer questions but sent his representatives instead.
ACB is probing alleged irregularities in the multi-crore project in Raigad district upon directions of Maharashtra government.
During its probe, the ACB's Special Investigation Team (SIT) had registered offences against as many as 11 accused, including six government officials, of which five accused have already been arrested.
Incidentally, ACB had summoned Pawar to its office as part of its probe earlier as well, but he had remained absent.
Calling him to their office once again today, ACB had given Pawar the option of either appearing in person or through his counsel.
Pawar, who held the irrigation portfolio in Maharashtra when the irregularities took place, was represented by Sunil Musale and two other advocates.
According to ACB, Pawar could not be present in person since he was busy with ongoing festivities.
