On your type material tank, NOTHING will bond. The only fix is plastic welding.
Not true! I found this JB Weld Plastic Bonder that will bond to thermoplastics, including polyethylene like this water tank. This is available in most big box stores by the glue.

The previous owner of my truck camper cut a big section out of the propane compartment liner trying to fix some water damage. I used 3 tubes of the JB Weld Plastic Bonder to seam it back to back together and it's strong as new.

It's hard to see from the pic where the OP's water tank is leaking but sometimes if it's in the thread an extra-heavy wrap of teflon tape can work temporarily.
