"Building storm drains and building storm sewers located underneath a building and to a point three feet outside the building shall be of cast-iron pipe where the size required is 15 inches or less. When the required hydraulic capacity of the storm drain would result in the use of a pipe in excess of 15 inches, the use of reinforced concrete pipe may be permitted. Such installation shall require the prior approval of the City Engineer as to the capa- bility of the reinforced concrete pipe to sustain the design load imposed upon it." SECTION 2.

These amendments have been reviewed by Lone Star Gas Company and other local organizations concerned with the enforcement �--� of the Plumbing Code. Highlights of Proposed Amendments Section 29-16 - Storm Drains The proposed amendment to this section of the Plumbing Code as recommended by the Plumbing Board restricts the size of storm drains beneath buildings to 15 inches in diameter and the material to cast-iron pipe. The Plumbing Board notes that cast iron pipe has fewer joints and better in-place joint characteristics and feels that the placement of cast iron pipe storm drains beneath buildings will result in superior performance which will more than offset a slight increase in cost. The Public Works Department recommends that the Plumbing Code permit the use of concrete pipe in sizes larger than 15 inches beneath buildings when the pipe will sustain the design load imposed upon it. The Public Works staff feels that use of concrete pipe is widely accepted and that recent improvements in joint construc- tion have removed the major objection to its use. The staff also recommends that "except as provided in Ordinance 5877" be inserted at the end of the first sen- tence of the fourth paragraph of Section 29-16 of the proposed amendment. Ordi- nance 5877 allows the discharge of storm water into sanitary sewers under certain, specific conditions and establishes rates for such discharge. Section 29-34 Gas Service - FinaZ Inspection and Tests Present ordinance provisions are designed to eliminate gas leaks, but enforcement of them in the field results in redundant tests, excessive stand-by time, lengthy disruption of service, and makes no provisions for emergency conditions. The proposed amendments revise inspection procedures to allow the gas utility company and contractors to work together to accomplish a safe, fast installation and at the same time maintain current standards of public safety and inspection criteria. Section 29-46 Water Service SuppZg - Pipes and Fittings The proposed amendment is written to reduce the incidence of leaking water pipes in slab-type foundations by requiring the installation of insulated copper pipe in specified ways. This provision is not contained in the current Code. DATE REFERENCE SU13JECT: Proposed Amendments to _PAGE 8/5/68 NUMBER G - 1268 Plumbing Code Section 29-51 - Gas Pipe and Fittings Over the years, Fort Worth has continually upgraded gas line installati(uijre�qu re- ments from no requirements to the current requirements of doped and wrapped pipe electronically tested before the pipe is buried. Despite these procedures, the City is encountering an increasingly higher percentage of leaks in gas service lines less than five years old. The proposed amendment specifies types and sizes of gas pipe to be used and estab- lishes guidelines for its installation, including joints, in order to reduce main- tenance problems caused by corrosion of gas pipes by chemical agents in the soil. The proposed requirement of type "L" hard copper pipe will not completely eliminat service line failures, but it has significantly higher resistance to corrosion than less expensive pipe. It is anticipated that short-run increases in costs for the pipe will be more than offset by its increased reliability and decreased maintenance costs. Section 29-97 - Shover Baths Several years ago, the Plumbing Code was amended to permit the use of the inexpen- sive composition or "built-up" type shower pan. Almost without exception, these pans have proven to have a short life, often resulting in undetected leaks that cause expensive damage to structures housing them. The proposed amendment restores the sheet lead pan previously required and speci- fie� that the pans must be recessed three inches in slab foundation construction to minimize damage if a leak does occur. Recommendation It is recommended that the proposed amendments to the Plumbing Code attached to this correspondence including the additions to Section 29-16, Storm Drains, suggested by the Public Works Department as described above, be approved by the City Council.
