He also expressed the hope that the Punjab chief minister would honour the Supreme Court's orders on the issue.
In a statement, Khattar said, "I thank the Supreme Court for its orders on the Satluj-Yamuna-Link (SYL) canal issue. The apex court has done justice".
He said he appealed to Singh to cooperate in the construction of the canal in Punjab.
Punjab is opposed to the construction of SYL canal, saying it does not have surplus water to share with Haryana.
Yesterday Haryana's main opposition INLD had staged a protest by blocking roads and disrupting movement of vehicles entering the state from Punjab over the issue.
