Joe Lycett vs Sewage
9pm, Channel 4
Last year, the comedian launched a poo podcast with Gary Lineker, who discussed his World Cup pitch diarrhoea. It turned out to be a stunt, and this informative but hilarious documentary tells the story behind it. “How have we got to the point where it’s like: ‘Oh yeah, there’s just loads of shit in the water?’” he asks before investigating water company sewage leaks. He makes some vile discoveries – “The more spills reported, the less of a bonus you get,” one anonymous sewage worker says. Hollie Richardson

10pm, BBC Four
“If a country can’t tolerate someone like him, the country is the problem,” says Zijuan Chen of her imprisoned husband, human rights lawyer Chang Weiping. This documentary is a startling insight into state surveillance in China; it is deeply troubling to see how slickly data and digital technology can be used to subjugate a population. Truly dystopian.

Kin
10.40pm, BBC One
This atmospheric Irish crime drama continues to simmer absorbingly. One of its strengths is its preference for ominous but low-key family politics over gratuitous fireworks.
