§ 1042.10 SEWER GRADE AND DIRECTION.

   The building sewer shall be laid at uniform grade and in straight alignment insofar as possible. All changes in direction and/or depth shall be made through the use of pipe fittings meeting the same specifications as set forth in § 1042.09 to tie in existing building sewers and the test tee required at the property line. No angles, either horizontal or vertical, shall be greater than 45 degrees along the length of the building sewer.

(Ord. 1979-33, passed 5-7-1979)

§ 1042.11 JOINTS GASTIGHT AND WATERTIGHT.

   All joints and connections shall be made gastight and watertight. The City Engineer may require the sewer tapper to demonstrate the watertightness of the joints by such tests as may be necessary.

(Ord. 1962-69, passed 6-4-1962)

§ 1042.12 MINIMUM FALL.

   The building sewer shall have a minimum fall of one-eighth inch per linear foot from the building to the public sewer. The City Engineer may, by special permission in each case, authorize the building sewer to be constructed with a fall less than one-eighth inch per linear foot if he or she determines such procedure to be necessary and desirable.

(Ord. 1962-69, passed 6-4-1962)

§ 1042.13 PIPE INTERIOR TO BE CLEAN.

   The interior of each length of pipe shall be made perfectly clean and free from offsets, fins and projections before the next length is connected thereto. All building sewers shall be graded by line and pole, the line being first leveled from the building to the lateral or public sewer and then lowered at the lateral end to obtain the required fall.

(Ord. 1962-69, passed 6-4-1962)

§ 1042.14 LOCATION AND DEPTH.

   Building sewers shall not be constructed closer than three feet to any exterior wall, cellar, basement or cistern, and the depth shall be sufficient to afford protection from frost.

(Ord. 1962-69, passed 6-4-1962)

§ 1042.15 SEWERS CROSSING UNSTABLE SOIL OR CLOSE TO TREES.

   Where the building sewer will cross unstable soil or be close to a tree where roots may enter the joints, extra heavy cast-iron pipe with suitable joints may be required.
