Arcadia Municipal Code Part 8 House and Industrial Connection Sewer Construction

Every connection with a public sewer shall be made in the manner and with such materials as are prescribed by this Part.

All pipe shall be either clay or cast iron. All clay pipe six (6) inches or more in diameter shall be first class vitrified glazed or unglazed. All clay pipe four (4) inches in diameter shall be first class vitrified clay pipe ceramic glazed in the inside. All cast iron pipe six (6) inches in diameter or less shall be standard cast iron soil pipe. That portion of the pipe extending from the public sewer to the property line shall be not less than six (6) inches in internal diameter. That portion extending from the property line to the house or building, shall be not less than four (4) inches in internal diameter, for house connection sewers laid on a grade of ¼ inch per foot or more and serving one hundred eighty (180) fixture units or less, as shown in the following table:

FIXTURE UNIT EQUIVALENTS

and not less than six (6) inches in internal diameter for all portions of house connection sewer serving more than one hundred eighty (180) fixture units, with the following exceptions:

(1) For waste lines only, two (2) inch cast iron pipe, not to exceed twenty-five (25) feet in length, may be used to receive the discharge from a vented waste pipe sized two (2) inches or less.

A six (6) inch by (4) inch reducer shall be inserted in the sewer just inside the property line when the pipe size is changed from six (6) inch to four (4) inch. A six (6) inch by four (4) inch by four (4) inch reducer tee may be used at this location to serve as reducer, test tee and clean-out.

Clean-outs shall be placed in every house connection sewer at the junction with the soil pipe at the building; at the junction with the main line sewer, or at the junction of the reducer and the four (4) inch pipe at the property line; at all changes in alignment and grade, above or below the point of change; and at intervals of not to exceed fifty (50) feet in straight runs. Clean-outs in straight runs longer than fifty (50) feet shall be uniformly spaced.

The clean-out in vitrified clay pipe house connection sewer shall be made by inserting either a "T" or "Y" branch in the line with the clean-out hub placed vertically above the flow line of the pipe. A cap of the same material shall be tightly sealed in the bell of the access or vertical outlet.

A clean-out in a cast iron soil pipe house connection sewer shall be made by inserting a single cast iron soil pipe standard "T" or "Y" branch in the line with the cleanout hub placed vertically above the flow line of the pipe. A cast iron ferrule threaded for a three and one-half (3-½) inch plug shall be lead jointed into the bell of the access or vertical outlet. A brass plug three and one half (3-½) inches in diameter having eight (8) threads per inch and weighing approximately two (2) pounds, eight (8) ounces shall be securely screwed into the ferrule.

Where a cast iron pipe smaller than four (4) inches connects to the four (4) inch house connection pipe, a suitable adapter shall be inserted in the line.

All pipe shall be laid up grade on an unyielding foundation, true to line and grade and with a uniform bearing under the full length of the barrel of the pipe. Bell and spigot pipe shall be laid with sockets up grade. Suitable excavations shall be made to receive the bells or collars of the pipe. All adjustments to bring the pipe to line and grade shall be made by scraping away or filling in under the body of the proper and not be wedging or blocking.

Vitrified clay piping shall not be placed closer than two (2) feet to the exterior wall of any building or closer than twelve (12) inches to the surface of the ground at any point in its course.

Whenever a house connection sewer is connected directly to a trunk sewer, either through a "Y", "T", saddle, house lateral, or manhole thereof, a "side hand hole trap" (running trap with clean-out of the same size) shall be inserted at the point or points of connection to the house plumbing one (1) foot inside property line, and the required "Y" or "T" clean-out shall be inserted in the line just below the trap.

The alignment and grade of a house connection sewer shall be straight from the public sewer to the street property line and shall be constructed at right angles to said main line sewer, except at cul-de-sacs and other special locations where exceptions may be granted by the City Engineer.

The grade of the house connection sewer inside the property shall be straight from the property line to the last or upper connection, and shall have a fall of not less than ¼ inch per foot, except where otherwise permitted in writing by the City Engineer.

All house connection sewers shall be laid by the most direct route feasible, free of pinched joints, changes of grade or unnecessary bends or fittings.

All excavations shall have sufficient width to allow proper workmanship and permit adequate inspection, and shall be supported in the manner set forth in the rules, orders and regulations prescribed by the Industrial Accident Commission of the State. Sheet piling and other timbers shall be withdrawn in such a manner as to prevent caving of the walls of the excavation or disturbance of the sewer pipe.

Where sufficient depth is available to permit, tunnels may be used between open cut trenches. Tunnels shall have a clean height of two (2) feet above the pipe, and shall be limited in length to one-half (½) the depth of the trench, but with a maximum length of eight (8) feet.

Before laying any sewer pipe in an excavation in soft, wet or spongy soil, sufficient gravel or crushed rock to stabilize the subgrade shall be placed in the bottom of the trench.

Where any portion of the sewer line other than cast iron soil pipe is located within ten (10) feet of any tree or hedge, the joints of the pipe shall be entirely encased in four (4) inches of Class "A" concrete or 1:2 mortar.

Materials excavated in streets and roadways shall be laid alongside of the excavation and kept trimmed up so as to cause as little inconvenience as possible to public travel. Free access must be provided to all fire hydrants, water gates, meters, and private drives, and means shall be provided whereby storm and wastewater can flow in the gutters uninterruptedly. All material excavated in streets and roadways, not required for backfilling, shall be immediately removed and disposed of by the permittee.

No person shall walk upon or disturb the pipe in any manner after the joints have been made.

All cast iron pipe joints shall be caulked and jointed with pig lead to the satisfaction of the City Engineer. All clay pipe joints shall be made with approved joint materials, to the satisfaction of the City Engineer.

Whenever it becomes necessary to connect a house connection sewer to a public sewer at a point where no "Y" or "T" branch has been installed in the public sewer, the connection shall be made in accordance with this Part by a Registered Sewer Contractor and in the presence of an inspector.

The "Y" and "T" saddle shall be installed by cutting a hole in the main line sewer pipe and fitting the saddle snugly in place with heavy twelve (12) gauge galvanized, asphalt painted iron wire bound around the main line pipe and the flange of the saddle. The "Y" saddle shall be placed in the side of the main line pipe with the "Y" branch upward at approximately forty-five (45) degrees from the horizontal and so pointed as to direct the flow from the house connection sewer down stream in the public sewer. The "T" saddle shall be placed in the top of the main line sewer pipe. "T" saddles shall be used only for the construction of chimney pipe.

After the saddle is in place an imbedment of cement concrete shall be placed under and around the main line sewer pipe and saddle as required for a standard chimney pipe. The inside of the point between the pipe and saddle shall be pointed with 1:2 cement mortar.

Every house connection sewer shall be constructed in such a manner as to withstand, when filled with water, a pressure of not less than two (2) pounds per square inch without leaking at any point.

Every house connection sewer shall be tested before being approved, in that portion extending from the property line to upper terminus thereof by a static water pressure test, which shall consist of filling the line or lines with water and carrying the level of the column of such water to a height sufficient to develop a pressure of two (2) pounds per square inch at the lower terminus thereof, and in no event to a height of less than four (4) inches above the top of the upper terminal end of such sewer; or, in lieu of such static water pressure test, by a pump test which shall consist of filling such line or lines with water, capping or sealing each upper terminus thereof, and applying an air pump at the property line in such a manner as to furnish an aggregate pressure of two (2) pounds per square inch in the sewer at the lower terminus.

If by reason of excessive fall in any such house connection sewer, the pressure in a static water pressure test exceeds four (4) pounds per square inch, such sewer may be tested in sections of such length that no such section or any portion thereof will be subjected to a pressure greater than four (4) pounds per square inch.

In the event that any joints of any house connection sewer are cemented with Portland cement mortar, no water tests shall be made thereof until the expiration of not less than twenty-four (24) hours after such joints are made.

All compound pipe joints shall not be water tested until the expiration of not less than one hour after pouring.

No house connection sewer shall be approved if any portion thereof, including any fitting, material, work or construction, fails to withstand the test herein provided for by leaking at any point.
