Arduino's appeal is that doing simple tasks is simple. The PRU is not easy. TI introduced a C compiler for the PRU last year, but until then it has been an assembly only affair. (I haven't tried the compiler, I just discovered it

They did that on a small scale to my brother's 40 year old copper natural gas connection in the US. Very fast compared to trenching in a new line. They just pulled a new corrosion proof line in behind the splitter head.
