The City is divided into two sewer service areas, one tributary to the easterly wastewater treatment facility (WWTF) and the other tributary to the westerly WWTF, divided by a WWTF division line that runs north/south through the City, to the east of Route 495.
(b) 
A total of 4.15 million gallons per day (mgd) average daily flow is allocated in the CWMP/EIR Certificate to the westerly WWTF from the City of Marlborough and the Town of Northborough as described further in Subsection A(8)(b)[1] and [2] below. The actual allowable flow is dependent upon the permitted value in the facility's National Pollutant Discharge Elimination System (NPDES) permit. Sewer connection or extension permits shall only be approved if the resulting total flows to the westerly WWTF are within the permitted flow allocation in the NPDES permit and if the flows are consistent with the following allocations:
[1] 
Up to 2.9 mgd of the total permitted average daily flow is allocated in the CWMP/EIR certificate to originate from the western side of the City of Marlborough tributary to the westerly WWTF through the year 2025.
[2] 
The remaining allocation between 2.9 mgd and the NPDES permitted average daily flow (up to 1.25 mgd) is allocated in the CWMP/EIR certificate to originate from the Town of Northborough tributary to the westerly WWTF through the year 2025. Note that the City of Marlborough is required via a January 1, 1990, intermunicipal agreement to provide the Town of Northborough with 0.80 mgd of sewer capacity; however, this agreement expired as of January 1, 2010.
(c) 
The flow limitation for the easterly WWTF in effect on the date of the December 3, 2007, certificate was 5.5 mgd on an average monthly basis, as permitted by the easterly WWTF's October 19, 2006, NPDES permit. Sewer connection or extension permits through the year 2025 shall only be approved if the total flows to the easterly WWTF are within this permitted flow allocation.
(d) 
All flow allocations in the CWMP/EIR certificate, as well as sewer connection or extension estimated flows, shall be based on average annual values.
(e) 
Extensions tributary to the easterly WWTF originating from beyond the area bounded by the town boundaries to the north, south and east, and by the WWTF division line to the west require approval by the Mayor, the City Council, and, when applicable thresholds are exceeded, by MassDEP via a sewer extension permit. Similarly, sewer extensions tributary to the westerly WWTF beyond the area bounded by the WWTF division line to the east, the town boundaries to the north and south, and the neighborhoods identified for sewering in the CWMP/EIR in Northborough to the west require approval from the Mayor, City Council, and, as applicable, MassDEP. Flow from one side of the WWTF division line may be treated at the WWTF on the other side with prior City Council approval.

(2) 
When the Commissioner determines that a user(s) is discharging or proposing to discharge to the POTW any of the above enumerated substances in such amounts as to interfere with the operation of the POTW, the Commissioner shall advise the user(s) of the impact of the contribution on the POTW and develop effluent limitation(s) for such user to correct the interference with the POTW.
(3) 
All industrial users are required to give the City (POTW) notice of the discharge of substances which would constitute hazardous waste if otherwise disposed of. Said notice shall be given to the City 14 days prior to discharge or immediately upon discovery of an unintended discharge.
D. 
Federal Categorical Pretreatment Standards.
(1) 
Upon the promulgation of the Federal Categorical Pretreatment Standards for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under this chapter for sources in that subcategory, shall immediately supersede the limitations imposed under this chapter. The Commissioner shall notify all affected users of the applicable reporting requirements under 40 CFR 403.12.
(2) 
Where the City's wastewater treatment system achieves consistent removal of pollutants limited by federal pretreatment standards, the City may apply to the approval authority for modification of specific limits in the federal pretreatment standards. "Consistent removal" shall mean reduction in the amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment system to a less toxic or harmless state in the effluent which is achieved by the system in 95% of the samples taken when measured according to the procedures set forth in Section 403.7(c)(2) of Title 40 of the Code of Federal Regulations, Part 403, General Pretreatment Regulations for Existing and New Sources of Pollution, promulgated pursuant to the Act. The City may then modify pollutant discharge limits in the federal pretreatment standards if the requirement contained in 40 CFR 403.7 are fulfilled and prior approval from the approval authority is obtained.
(3) 
Except where expressly authorized to do so by an applicable categorical pretreatment standard, no user shall ever increase the use of process water or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the categorical pretreatment standard. Mass limitations may be imposed on users when determined by the authority to be appropriate.

Action by Commissioner.
(1) 
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in Subsections C and E of this section and which, in the judgment of the Commissioner, may have a deleterious effect upon the sewerage facilities, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Commissioner may do any or all of the following:
(a) 
Reject the wastes and require separate treatment.
(b) 
Require pretreatment to an acceptable condition for discharge to the public sewers.
(c) 
Require control over the quantities and rates of discharges.
(2) 
If the Commissioner permits the treatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Commissioner and subject to the requirements of all applicable code, ordinances and laws.
G. 
The City reserves the right to establish, by ordinance, more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives of this chapter.
H. 
Grease, oil and sand interceptors shall be provided when, in the opinion of the Commissioner, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand or other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Commissioner and shall be so located as to be readily and easily accessible for cleaning and inspection.
I. 
State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those in this chapter.
J. 
Where pretreatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
K. 
The owner of any property serviced by a building sewer carrying industrial wastes shall perform such monitoring of its discharges as may be required by the Commissioner, including the installation, use and maintenance of monitoring equipment. Records of the results of such monitoring shall be kept, and said results shall be reported to the Commissioner. The Commissioner shall make such records available upon request to state, federal or any other public agencies having jurisdiction over such discharges. In addition, the owner of any property serviced by a building sewer carrying industrial wastes shall, at the discretion of the Commissioner, install a suitable control manhole to facilitate monitoring of the wastes in the building sewer as may be required by the Commissioner. Such manhole shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Commissioner. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible to the Commissioner at all times.
L. 
Measurements, tests and analyses.
(1) 
Except as noted in this subsection, all measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, and shall be determined at the control manhole provided or upon suitable samples taken at such control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewerage facilities and to determine the existence of hazards to life, limb and property. The particular analyses involved will determine whether a twenty-four-hour composite of all outfalls of a property is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
(2) 
Measurements, tests and analyses of the characteristics of waters and wastes discharged by significant users shall be performed in accordance with procedures established by the EPA pursuant to Section 304(g) of the Act and contained in 40 CFR 136, as amended.
M. 
Accidental discharge.
(1) 
Each significant user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner's or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the City for review and shall be approved by the City before construction of the facility. All existing significant users shall submit such a plan by October 1, 1985.
(2) 
No user who commences contribution to the POTW after the effective date of this chapter shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the City. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this chapter. In the case of an accidental discharge, it is the responsibility of the users to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume and corrective actions.
(3) 
The City of Marlborough (POTW) shall evaluate the significant industrial users (SIUs) every two years. Each user shall be required to comply with any plan the City considers necessary, pursuant to this section.
N. 
Written notice. Within five days following an accidental discharge, the user shall submit to the Commissioner a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, fish kills or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this chapter or other applicable law.
O. 
Notice to employees. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees of whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.
P. 
No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, provided that such agreements do not contravene any applicable state or federal regulations.
Q. 
No person shall discharge industrial wastes to the public sewers, except in accordance with the conditions set forth in an industrial waste discharge permit issued by the Commissioner to that person.

(2) 
Any and all plans for a sewer system in the City of Marlborough will show and/or specify the following: All gravity mains will be a minimum of eight inches in diameter; all laterals, interceptors, trunklines, etc., will be either asbestos cement, cast iron, reinforced concrete or polyvinyl chloride (PVC). The class of pipe will accommodate the field conditions, i.e., all asbestos cement sewer pipe up to twelve-foot bury can be Class 2400; 12 to 18 feet will be Class 3300; 18 to 24 feet will be Class 4000; and anything over 24 feet will be Class 5000. No Class III concrete pipe shall be used for sewer construction. Class IV will be used up to a twenty-foot bury, and anything over 20 feet will be Class V; PVC pipe shall meet or exceed the ASTM D-3034, SDR 35 requirements. PVC pipe shall not be used for pipes with diameters greater than 15 inches unless expressly approved in writing by the Commissioner of Public Works. When the cover is five feet or less under a roadway, the class and type of pipe will be specified by the Department of Public Works. The stationing and slopes of all pipes will be shown on a plan and profile view with an appropriate scale. The distance between any two manholes shall never exceed 300 feet. Any two sewer lines entering a manhole or a structure with a difference in elevation greater than three feet zero inches, the pipe with the higher elevation will enter via an outside drop connection and will be shown as a drop manhole on the plans. All sizes of all pipe will have as their minimum slope that slope which yields the scouring velocity for the particular diameter pipe. A bench mark shall be provided every 500 feet. Any and all existing utilities within 30 feet of the proposed main will be shown and, if available, their elevations noted.
(3) 
Any contractor involved in sewer construction in the City of Marlborough will strictly adhere to the provisions as set forth in § 510-5. No equipment, tools or material will be rented or loaned from the Department of Public Works. All materials used must be of the same make and quality as set forth hereinafter.
(4) 
Costs. All labor and material costs to install a sewer system as specified herein will be borne by the owner, developer or contractor, whatever the case may be. Costs for taps into the public system and the restoration thereof of any public way will be borne by the owner, developer or contractor.
(5) 
Inspection will be provided by the City of Marlborough only on a limited or part-time basis. Before any backfilling is done, the Department of Public Works' Water Division will be notified 24 hours in advance, and a man will inspect the completed work. If the Department of Public Works feels that insufficient workmanship and care is being taken in the installation, a man will be assigned from the Department of Public Works on a full-time basis. The contractor or owner will bear the cost of this man at his hourly wage rate, Monday through Friday, from 7:30 a.m. to 4:30 p.m., or in the case of summer hours, 7:00 a.m. to 3:30 p.m. Any time spent on the site not within these limits or Saturday, Sunday, holidays, etc., will be at twice the man's rate.
(6) 
Excavation in any public way will require a road opening permit from the Department of Public Works. Necessary forms may be obtained and filed with the Department of Public Works' Street Division. It will be the contractor's responsibility to notify utility companies, such as gas, telephone, electric, etc., if there is any possibility of their equipment or their property being jeopardized by excavation. It shall also be the contractor's responsibility to notify the Fire Department and Police Department of said work to be performed and, if necessary, to hire uniformed police for traffic control. In the event that the roadway cannot be restored to its normal surface immediately following the work, sufficient care will be taken to make the roadway smooth for traffic and, if necessary, to light with flashers as a warning to motor vehicles.
(7) 
Before any sewer mains, water mains or drain lines are installed in a new subdivision or development, the contractor will bring the entire site where these utilities are located to subgrade, such grade will be verified by grade stakes provided and set by a registered land surveyor or engineer employed by the owner or contractor, so that the Engineering Division of the Department of Public Works may expedite its checking of such grades.
(8) 
All materials used shall be specified in Subsection B, Work performed by developers and/or private contractors. All sewer mains and sewer services will be set in a screened gravel bed, three-fourths to one-inch stone. The stone bed will always be on firm undisturbed earth. In the event of peat or wet clay at grade, the contractor will excavate enough material so that, when backfilled with stone, it will provide a sound bed. The determination of how much unsuitable material is to be excavated will be at the immediate discretion of the Inspector of the Department of Public Works. All concrete pipe shall be jointed by the use of a flat rubber gasket or the O-ring type. All cast iron for sewer shall be the same class for gravity and force main systems; all force main systems will be cast iron. Under normal conditions, all pipe will have a six-inch envelope of screened gravel aground it. In ledge, this envelope will go to eight inches. Select material will immediately follow the stone over the pipe and, as to the amount, will depend upon the depth and whatever the Inspector deems necessary, at which time normal backfilling may start, using already excavated material.
(9) 
Manholes may be poured in place, precast or, at the discretion of the Department of Public Works, be Barrel Block and plastered both sides. All manholes will have aluminum steps on a one-foot-zero-inch spacing. All precast sections will be made watertight by O-ring joints or an approved mastic. Connections to manholes may be Mortar Joint, Lock Joint Flexible Manhole Sleeve, Press Wedge II, Kor N Seal and Res Seal. The exterior of all manholes shall be completely covered with a bituminous waterproofing.
(10) 
Manhole rings/covers shall be of the same type as used by the Department of Public Works.
(11) 
Brick inverts. All sewer manholes will have a brick table constructed in their base to meet all incoming and outgoing pipes to that the flow is channeled smoothly from one point to another. All brick used for manholes inverts will be a hard-burned sewer brick to meet ASTH C32-69 Grade SS. Brickwork will also be used between the manhole structure and ring and ring cover to give the desired grade. However, the brickwork in this area will never exceed eight inches. This brickwork can be with a common brick.
(12) 
Thrust blocks will be used on any force main sections where called for by the Department of Public Works.
(13) 
Chimneys will be employed on the main wherever a service is needed when the depth of the main exceeds eight feet zero inches. This will meet exception when the elevation of the connection at the building does not allow the use of a chimney. All chimneys will be encased in a concrete envelope six inches thick.
(14) 
Y-branches and/or tees will be employed in the main for depths of eight feet zero inches or less. All Y-branches, tees, chimneys, etc., will be provided with proper end caps until the time that the completed tie-in is made.
(15) 
Tap to main. Main-to-main connections will only be made by the use of a manhole as specified in § 510-19B(2) or, in the case of a service, by use of a tapping saddle approved by the Department of Public Works.
(16) 
Building sewers.
(a) 
All building sewers will be either asbestos cement, cast iron or polyvinyl chloride (PVC) having a minimum diameter of five inches and shall conform to the following specifications: Asbestos cement pipe ASTM C 428-67, cast iron pipe ASTM A74-66 and PVC ASTM D-3034, SDR 35. Joints shall be tight and waterproof. Cast iron shall be used when passing under or through any wall or footing of a building. If installed in filled or unstable ground, the building sewer shall be laid on a suitable concrete bed or cradle or shall be cast iron or as approved by the Department of Public Works.
(b) 
The size and slope of the building sewer shall be subject to the approval of the Commissioner but in no event shall the diameter be less than five inches. The slope of such pipe shall not be less than 1/4 inch per foot. The building sewer shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with benched manholes or curved pipe and fitting, as approved by the Commissioner. A cleanout shall be located on the exterior side of the building service and shall be in a place that is accessible for maintenance by the Department of Public Works or others.
(c) 
All parts of new building drains and sewers shall withstand, under test without observable leakage, a ten-foot head or water for a minimum period of 15 minutes at a temperature above the freezing point of water.
(d) 
The connection of the building sewer into the public sewer shall be made at the Y or T-branch or at bench level in a manhole if such branch tee or manhole is accessible.
(e) 
If no branch, tee or manhole is available, a connection may be made by tapping the existing sewer by an approved method.
(f) 
No person shall make connection of roof drains, downspouts, foundation drains, areaway drains, basement drains, sump pumps or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
(17) 
Leakage tests for gravity sewers.
(a) 
The pipeline shall be made as nearly watertight as practicable, and leakage tests and measurements shall be made on sections of approved length.
(b) 
The contractor shall furnish suitable test plugs, water pumps and appurtenances and all labor required to properly conduct the leakage tests on the pipeline.
(c) 
Upon completion of a section of the sewer, the contractor shall dewater it and conduct a satisfactory test to measure the infiltration for at least 24 hours. The amount of infiltration, including manholes, Y-branches and connections, shall not exceed 300 gallons per inch of diameter per mile of sewer per 24 hours. The contractor shall be responsible for the satisfactory watertightness of the entire section of sewer and shall satisfactorily repair all joints or other locations that are not sufficiently watertight.
(d) 
For making the infiltration tests, underdrains, if used, shall be plugged, and other groundwater drainage shall be stopped to permit the groundwater to return to its normal level insofar as practicable.
(e) 
Where practicable, the leakage test shall be made at a time when the groundwater is at least one foot above the top of the pipe of the highest section of work being tested.
(f) 
Suitable bulkheads shall be installed, as required, to permit the test of the sewer.
(g) 
Where the groundwater level is less than one foot above the top of the pipe at its upper end, the sewers shall be subjected to an internal pressure by plugging the pipe at the lower end and then filling the pipelines and manholes with clean water to a height of two feet above the top of the sewer at its upper end. Where conditions between manholes may result in test pressures which would cause leakage at the stoppers in branches, provisions shall be made by suitable ties, braces and wedges to secure the stoppers against leakage resulting from the test pressure.
(h) 
The rate of leakage from the sewers shall be determined by measuring the amount of water required to maintain the level two feet above the top of the pipe.
(i) 
Leakage from the sewers under test shall not exceed the requirements for leakage into sewers as hereinbefore specified.
(j) 
The sewers shall be tested before any connections are made to buildings.
(k) 
The contractor shall construct weirs or other means of measurement as may be required, shall furnish water and shall do all necessary pumping to enable the tests to be properly made.
(l) 
Should the sections under test fail to meet the requirements, the contractor shall do all work of locating and repairing leaks and retesting as the Engineer may require without additional compensation.
(m) 
If in the judgment of the Inspector or the Department of Public Works it is impracticable to follow the foregoing procedure exactly for any reason, modifications in the procedure shall be made as required and approved, but in any event, the contractor shall be responsible for the ultimate tightness of the line within the above test requirements.
(18) 
The contractor shall furnish to the City of Marlborough, Department of Public Works, upon completion of the job, a set of as-built plans which will indicate the following: invert elevations of all pipes at any structure or manhole; rim elevations of all structures or manholes; the correct slope on all pipe between structures or manholes in feet per foot; the exact location of chimneys and Y-branches on the main and, in the case of chimneys, the vertical height over the top of the pipe; the exact location of when the building sewer enters onto private property from any City street or easement. This location will be pinned down by at least two ties from permanent or fixed object. This same method will be used for locating cleanouts when the service connection is made to the building.
(19) 
Warning ribbons. If nonmetallic pipes are used in the installation of any sewer main or service pipe, a warning ribbon shall be used. Said ribbon shall be green in color and imprinted with the words "caution sewer line below," or words of similar intent, and shall be metallic to provide for future locating with inductive tape locators. Depth of burial shall be in accordance with the manufacturer's standards, except that burial shall not be at a depth less than 18 inches nor at a depth greater than 48 inches.
The Commissioner shall make regulations and impose civil penalties and fines.
