- (a) In multi-liner systems, the bottom most liner system shall also be the leak detection and location system.
- (b) In single-liner systems, a leak detection and location system shall be installed beneath the bottom most liner, unless the potential for leakage is reduced by installing a composite liner that meets the requirements of Env-Sw 805.04(c).
(c) A leak detection and location system shall be designed to:
- (1) Convey liquids to an observation point for detection, based on a maximum time of concentration equal to 24-hours under saturated hydraulic conditions; and
- (2) Provide a means for isolating the potential location of a leak.
