Madras, now Chennai, faced water loss across its distribution network which strained resources and affected equitable service. The project identified root causes of loss and implemented effective solutions via representative districts and sub districts and used methods developed for intermittent low pressure supplies. Small areas were isolated and pressurised with mobile tankers and pumps and advanced equipment such as leak noise correlators, sounding rods and data loggers was used to locate and quantify leaks.
