The first link ("claimed") is now dead. Joseph Lauer (whose e-mail drew my attention to this article) notes the following:
It is from the https://www.facebook.com/Aqsai2014/ Facebook page and the URLs for the likely relevant pictures (followed by the offered caption translations) are:I do not know whether the claim about repairing water leakage is true or not. The past record of the Waqf's unauthorized digging on the Temple Mount does not encourage one to accept any such claim without verification. But even if it is true, it is irrelevant. Excavation at an archaeologically rich site like the Temple Mount is always to be undertaken under the supervision of archaeologists and only with any necessary salvage archaeology being done as needed. You don't just go and dig a big hole to fix a leak in a canal. Archaeological supervision and salvage under such circumstances is standard practice pretty much everywhere else and failure to follow that practice is simply uncivilized.
