(b) If the system is not fully metered, a program to install meters on all un-metered Water Service Connections.

(A) Within two years of approval of the water management and conservation plan, the water supplier shall provide a description identifying potential factors for the loss and possible actions for remedy;
(B) If actions identified under subsection (A) do not result in the reduction of water loss to less than 15 percent, within five years of approval of the water management and conservation plan, the water supplier shall develop and implement a program to detect and repair leaks in the transmission and distribution system using methods and technology appropriate to the size and capabilities of the Small Municipal Water Supplier, a line replacement program detailing the size and length of pipe to be replaced each year, or a similar program that will result in a reduction of Water Losses.
