Could buyers of older London homes face $10K bill to aid Thames River?

City politicians are queasy about a proposal that would cut stormwater and sewer discharge into the Thames River – but add as much as $10,000 to the cost paid by buyers of many older London homes.

Monday, they considered the notice of completion of city hall’s pollution prevention and control plan update study, which aims to refine London’s long-term strategy for managing its sewage flow, including the causes of overloads.

Chief among its recommendations is mandating the disconnection of weeping tile drainage systems, “a significant contributor” to London’s “high level” of water inflow and infiltration into its sewage system, city staff say.

They recommend mandating the weeping tiles to be disconnected in an estimated 50,000 homes when each home is sold, at a cost of $5,000 to $10,000 t
