Not by me. Based on earlier digs, USVI gets a lot of potable water through desalinization. Though that does take a lot of electricity.
The waste from that process might explain the effluent from the pipes. Epstein had at least two swimming pools on LSJ. He'd be sucking down an enormous amount of electricity to run desalinization but with money as no object, maybe so.
Either that or just get it delivered.
