§ 25-87. Inspection.

(a)

Prebackfill inspection. Irrigation systems shall be inspected prior to backfill, and must be requested by the applicant. Installation deficiencies or defects discovered during the inspection shall be corrected before the system is considered approved for use. The city shall utilize a licensed irrigation inspector or a plumbing inspector to perform inspections, and the inspector shall document on the inspection record the static pressure and water source of the irrigation system.

(b)

Final inspection. Upon completion of a permitted irrigation system, a final acceptance inspection shall be perform by the city, prior to the system being put into services by the end user. The final inspection shall include a permit closeout procedure, and shall include the following steps:

(1)

The applicant's request for final inspection shall include a copy of the initial passing test results for the backflow device (if applicable). The date of the test shall establish the anniversary date for future annual tests.

(2)

The applicant shall furnish the city inspector with an as-built record drawing and hydraulic calculation for the installed system.

(3)

The applicant shall demonstrate, to the satisfaction to the inspector, that the system mainline holds static pressure within an acceptable tolerance. The method for performing the hydrostatic test shall be at the discretion of the inspector acceptable toleration level must be at two (2) pounds per square inch.

(4)

The applicant shall demonstrate the performance, coverage and operation of the system by running each zone for not less that five (5) minutes. In order for the system to be accepted, performance and coverage must match the design within a reasonable tolerance, must meet or exceed TCEQ minimum standards, and be within manufacturer's recommendations for the equipment used.

(5)

The inspector shall witness the demonstration, and verify starting and ending consumption readings on the water meter for each zone. Actual water consumption for each zone, calculated over a minimum run time for five (5) minutes, shall not exceed the calculated consumption by more than fifteen (15) percent. In the event the water consumption for any zone fails to match design calculations within tolerance, the applicant shall be required to cap emission devices and demonstrate that the section piping hold static pressure. Once the applicant has repaired leaks and verified proper installation of emission devices, calculated consumption figures will be replaced with actual consumption results for establishing the final seasonal water schedule.

(6)

The applicant shall furnish the inspector with a copy of the required maintenance checklist, including all of the items listed in 30 TAC 344.63.

Upon satisfactory completion of items (1) through (6), the city shall issue a certificate of final inspection, and the approved irrigation system shall be assigned a tracking number. The backflow preventer information, and the irrigator's name and license number shall be maintained in the city records. If the irrigation system is being constructed as part of the building permit, a certificate of occupancy shall not be issued until the irrigation system permit has been closed out with the final acceptance.
