Summary
Lafayette allows rainwater collection and nonpotable water reuse systems but holds owners to a maintenance standard: Sec. 26-272(e) requires them kept safe and sanitary, and a system that isn't maintained, or that the owner stops using, has to be repaired or formally abandoned under the LCG Plumbing Code.
(e)Nonpotable water reuse systems. Nonpotable water reuse systems and rainwater collection and conveyance systems shall be maintained in a safe and sanitary condition. Where such systems are not properly maintained, the systems shall be repaired to provide for safe and sanitary conditions, or the system shall be abandoned in accordance with section 272(e)(1).(1)Where a nonpotable water reuse system or a rainwater collection and distribution system is not maintained or the owner ceases use of the system, the system shall be abandoned in accordance with the Lafayette City-Parish Consolidated Government Plumbing Code, as amended.

Full Breakdown
Sec. 26-272(e) sits in the PMC's water-system division, right alongside the rules for hot water, potable supply, and water heaters, which signals the city-parish treats a rainwater collection or nonpotable reuse system as part of the structure's regulated plumbing rather than a purely optional yard feature. The section doesn't set a tank size, catchment area, or a permit fee; it sets an outcome standard, safe and sanitary condition, and gives owners two paths when a system falls out of compliance: repair it back to that standard, or abandon it.
Abandonment isn't just disconnecting a hose; Sec. 26-272(e)(1) requires it to be done in accordance with the LCG Plumbing Code, which governs how a plumbing connection is properly capped, disconnected, or removed so it can't become a cross-connection or contamination hazard to the rest of the property's water system. This placement inside the water-system division, rather than a stand-alone stormwater or landscaping chapter, matters for enforcement: a complaint about a rainwater tank or reuse line runs through the same PMC plumbing-inspection channel as a leaking water heater or a broken sewer connection, not through a separate environmental or drainage code.
The building official enforces this the same way as the rest of the water-system division, through inspection under Sec. 26-257 and a correction order under Sec. 26-258 where an unmaintained system creates a hazard.
Violations & Fines
An owner who lets a rainwater collection or reuse system deteriorate into an unsafe or unsanitary condition, and neither repairs nor properly abandons it per the LCG Plumbing Code, is in violation of Sec. 26-272(e); the building official can order the defect corrected or the system abandoned, backed by the PMC's standard correction and hearing process.
