Construction.

Manner of installation.

[Amended 9-23-1968 by L.L. No. 22-1968]

The plumbing in the building shall be installed in such a manner that the main building drain will pass through the basement wall above the basement floor at such a point as to give the lateral a proper grade and proper cover. No basement floor drains shall be connected in any way.

If plumbing fixtures are installed in the basement or at any point below the first floor or the finished grade at the building, whichever is higher, a separate waste line shall be installed for each fixture and a manual gate valve shall be installed in each line, which gate valve shall be kept closed except when the fixture is in use. Plumbing fixtures installed below the house lateral shall be equipped with proper pumps with the necessary check valves, as directed by the Engineering Department.

In certain areas subject to flooding and/or sewer backup, as designated by the Engineering Department, or where requested or required by other regulating agencies, no plumbing fixtures other than laundry tubs below the first floor or the finished grade at the building, whichever is higher, shall be connected to the house lateral by gravity. If laundry tubs are connected by gravity, a manual gate valve shall be installed in the waste line from the tubs, which gate valve shall be kept closed except when the tubs are in use. Also, no fixtures, below the first floor or the finished grade at the building, whichever is higher, shall be connected to the house lateral by gravity in any multiple dwelling [two or more families] having living quarters below finished grade at the building regardless of the location of the building; in such cases these fixtures shall be equipped with proper pumps with the necessary check valves, as directed by the Engineering Department.

[Amended 8-9-1971 by L.L. No. 15-1971]

(d)

In cases of unusual construction where the above requirements are impractical, these requirements may be modified at the discretion of the Town Engineer.

Laterals shall be installed carefully to grade with tight joints. Laterals shall be installed with a slope of at least 1/4 inch per foot unless special permission is obtained from the Engineering Department.

The trench shall be excavated so as to meet the sewer at the Y-branch. The material excavated from the trench shall be so placed as to not obstruct the street and so as to cause the least inconvenience to the public. Proper barriers and lights shall be placed around the work.

(4)

In laying pipe, the trench shall be excavated to a depth at least four inches below the grade of the lateral. The trench shall be brought up to grade with four inches minimum compacted cushion of bank-run gravel or other similar material under the pipe. Said compacted material shall be well graduated, contain no stones over 3/4 inch and shall be satisfactory to the Engineering Department. Pipe shall be bedded carefully on the compacted material so that it does not ride on bells or joints. Backfill shall be by hand, free from stones, to a point 12 inches above top of pipe.

(5)

The ends of all house laterals not immediately connected with house plumbing shall be securely closed with a watertight stopper.

(6)

If any portion of the lateral crosses any existing or future public or private road, it shall have a minimum cover of four feet. If such cover cannot be obtained, pipe shall be encased with six inches of concrete. Backfill above pipe shall be in accordance with requirements of the appropriate highway authorities.

(7)

The Engineering Department will designate the position of the Y-branch in the street (or existing lateral under the street) as shown by the records on file, but the district will not be responsible for any errors in such locations.

(8)

The cover of the Y-branch (or existing lateral) shall be carefully removed so as to not injure the pipe or allow pieces of the cover to get into the sewer. The first length of pipe attached to the Y-branch shall be curved and set so as to give a good fall into the sewer.

(9)

Where Y-branches are not available, connection shall be by means of a factory made saddle, approved by the Engineering Department. The saddle and all necessary fittings and materials shall be furnished by the owner and the owner shall perform all excavation, backfill and other associated work. The actual installation of the saddle, including cutting into the sewer line, shall be performed by the Engineering Department. The owner or his representative shall give all assistance requested.

(10)

No septic tank shall be connected to any house lateral.

(11)

Regardless of whether or not any portion of the house lateral was installed by the district, the owner shall maintain, at his own expense, the entire house lateral from the house to the main sewer in the street, including any portion which may be located in or under the street.

§ 205-5 Streets.

Where any work is performed in street or highway rights-of-way, the owner or his agent shall first obtain a permit from the proper State, County or Town Highway authorities.

§ 205-6 Use of public sewers required.

It shall be unlawful to discharge to any natural outlet within the district any sanitary sewage, industrial wastes, or other polluted waters, except where interception or treatment has been provided in accordance with provisions of these rules.

The owner of all houses, buildings or properties used for human occupancy, employment, recreation, or other purpose, situated within the district and accessible to a public sanitary sewer of the district, is hereby required at his expense to install suitable toilet facilities therein, and to connect such facilities directly with the proper public sewer in accordance with the provisions of these rules, within 90 days after date of official notice to do so. Where such public sewer is not available, a private system satisfactory to the Erie County Health Department may be allowed by the Town Engineering Department.

§ 205-7 Use of public sewers.

The sewers herein described and referred to are "sanitary sewers" and are to be used for that purpose only. No underfloor drains, sump pumps, roof downspouts or other such facilities shall be connected thereto. No other surface water of any kind or cooling water or unpolluted industrial process waters shall be drained into the sanitary sewers.

Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:

Any liquid or vapor having a temperature higher than 150° F.

Any water or waste which may contain more than 100 parts per million, by weight, of fat, oil or grease.

Any gasoline, benzine, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas.

(4)

Any garbage that has not been properly shredded.

(5)

Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, manure, or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works.

(6)

Any waters or wastes having a pH lower than 5.5 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works.

(7)

Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage-treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewage-treatment plant.

(8)

Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage-treatment plant.

(9)

Any noxious or malodorous gas or substance capable of creating a public nuisance.

Grease, oil, and sand interceptors.

Grease, oil, and sand interceptors shall be provided when, in the opinion of the Engineering Department, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand and other harmful ingredients. All interceptors shall be of a type and capacity approved by the Engineering Department, and shall be located as to be readily and easily accessible for cleaning and inspection.

Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which when bolted in place shall be gastight and watertight.

Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation at all times.

Engineering Department review of certain discharges; pretreatment.

The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 parts per million by weight; containing more than 350 parts per million by weight of suspended solids; containing any quantity of substances having the characteristics described in § 205-7B; having an average daily flow greater than 2% of the average daily sewage flow of the district, shall be subject to the review and approval of the Engineering Department.

Where necessary in the opinion of the Engineering Department the owner shall provide, at his expense, such preliminary treatment as may be necessary to:

Reduce the biochemical oxygen demand to 300 parts per million and the suspended solids to 350 parts per million by weight.

Reduce objectionable characteristics or constituents to within allowable limits.

Control the quantities and rates of discharge of such waters or wastes.
