• IT seems evident that Thames Water is out of its depth in terms of understanding the risk posed by its ancient pipework or it is loath to spend money.
It could simply renew the largest old mains because, by definition, they will release the most water. Alternatively, it could employ automatic slam-shut valves that could close if a dramatic downstream drop in pressure was sensed.
Of course, this would lead to supply interruption but this happens anyway in the case of pipe failure. At least this protection would buy time for a response while reducing the large loss of water and consequential damage.
Does Thames Water employ engineers or just accountants?
