(5) Warranties for systems:

(a) On all installations of new irrigation systems, an irrigator shall present the irrigation system's owner or owner's representatives with a written warranty covering materials and labor furnished in the new installation of the irrigator system. The irrigator shall be responsible for adhering to terms of warranty. If the irrigator's warranty is less than the manufacturer's warranty for the system components, then the irrigator shall provide the irrigation system's owner or the owner's representative with applicable information regarding the manufacturer's warranty period. The warranty must include the irrigator's seal, signature, and date. If the warranty is part of an irrigator's contract, a separate warranty document is not required.

(b) An irrigator's written warranty on new irrigation systems must specify the irrigator's name, business address, and business telephone numbers, must contain the signature of the irrigation system's owner or owner's representative confirming receipt of the warranty and must include the statement; "Irrigation in Texas is regulated by the Texas Commission on Environmental Quality (TCEQ), MC-178, PO Box 130897, Austin, Texas 78711-3087. TCEQ's website is: www.tceq.state.tx.us."

(c) On all maintenance, alterations, repairs, or service to existing irrigation systems, an irrigator shall present the irrigation system's owner or owner's representative a written document that identifies the materials furnished in the maintenance, alternation, repair, or service. If a warranty is provided, the irrigator shall abide by the terms. The warranty document must include the irrigator's name and business contact information.

These fees will be in amounts sufficient to cover the city's costs in issuing and renewing the permits, including, but not limited to, staff time and other overhead costs. All permit fees will be based up the currently adopted fee schedule in § 150.016.

(Q) Enforcement.

(1) The city shall have the power to administer and enforce the provisions of this section as may be required by governing law. Any person, firm, corporation or agent who shall violate a provision of this code, or fails to comply therewith, or with any of the requirements thereof, is subject to suit for injunctive relief as well as prosecution for criminal violations. Any violation of this section is declared to be a nuisance.

(2) Any person violating any provision of this section shall, upon conviction, be fined a sum not exceeding $2,000. Each day that a provision of this section is violated shall constitute a separate offense. An offense under this section is a Class C misdemeanor, punishable by a fine of up to $2,000.

(3) Nothing in this section shall be construed as a waiver of the city's right to bring a civil action to enforce the provisions of this section and to seek remedies as allowed by law, including, but not limited to the following:
