Hunt­ing Renwick’s wa­ter leaks

Marlborough Express - The Saturday Express, Marlborough - - FRONT PAGE - JEN­NIFER EDER

Tech­ni­cians are work­ing their way through the streets of Renwick this week to iden­tify leaks in the un­der­ground wa­ter retic­u­la­tion sys­tem, us­ing acous­tic de­tec­tion equip­ment.

De­tec­tion So­lu­tions con­tracts man­ager Neil Scrut­ton says the process in­volves putting mi­cro­phones at ei­ther end of a pipe, one at a hy­drant and one at a valve, to record sounds in the pipes. ‘‘A leak cre­ates noise,’’ he says. ‘‘The time it takes for the sound to reach one end in­di­cates where the leak is.’’

Tech­ni­cians iden­ti­fied 60 po­ten­tial leaks in one day, but phase two of the process would re­quire check­ing the noise

‘‘Sta­tis­ti­cally, 60 per cent of leaks are pri­vate leaks. ’’
