Included in the list will be all industrial users which were not in compliance with the applicable pretreatment requirements during the previous 12 months. A summary of the control actions taken by the Commission or by the City will also be published in conjunction with the list.
The actual cost of each public drain or public sewer laid and constructed pursuant to an order of the City Council shall be paid for as follows:
A. 
One-half of the actual cost shall be paid by the City and the remaining 1/2 shall be assessed upon the estates benefited by the drain or sewer. For the purpose of apportioning the charge among the estates so benefited, 1/3 of such 1/2 of the cost shall be assessed upon the total frontage of the land so benefited on the street or way in which the drain or sewer is constructed, and each estate shall be assessed its proportional part thereof. Two-thirds of such 1/2 of the cost shall be assessed upon the total area of the land so benefited within a depth of 100 feet from the street or way in which the drain or sewer is constructed, and each estate shall be assessed its proportional part thereof.
B. 
In the case of estates which receive a direct benefit from the construction of a drain or sewer and have no assessable lot frontage and are not wholly located within 100 feet from the street or way in which it is constructed, so much of the area of the estates as may be deemed just and reasonable by the City Council shall be included in the total area as aforesaid and assessed its proportion of the cost in the same manner as land within 100 feet of the street or way.
C. 
Each corner lot abutting upon a street or way in which a drain or sewer is constructed and which receives benefit therefrom shall be assessed in accordance with the provisions of Subsections A and B above, including the whole frontage of the lot on the street in which the drain or sewer is first constructed, and, when a drain or sewer is constructed in the other street or way on which such lot abuts, so much of the frontage on the other street or way as the Mayor or City Council may deem just and equitable, not exceeding 50 feet thereof, and so much of the area of such corner lot as has been previously assessed shall be exempted from assessment.
D. 
The City Engineer shall keep an accurate account of the cost of each public drain and public sewer constructed by virtue of an order of the City Council, and, for the purpose of assisting the Council in assessing the estates benefited thereby, he/she shall furnish the Council with such information as to costs of drains and sewers, owners of abutting estates and other facts as may be necessary.

[Amended 5-21-2012 by Ord. No. 2012-158]
The City Engineer may, at any time, require such catch basins and traps to be introduced along the line of any private drain, or on the discharge of any fixture connecting therewith, as he/she may deem necessary for the proper maintenance of such private drain or of the main drain.
A. 
Private drains and building sewers shall be laid to and through the cellar wall and shall be provided with a cleanout in the direct line of the pipe.
B. 
All pipes through or under the wall of any building, and for a distance of eight feet outside of the wall or building, shall be of extra-heavy cast iron.
Subject to the provisions of § 228-62, every private drain or building sewer shall be under the control of, and shall be maintained and kept clean by, the City. All costs and expense incident to the installation and connection of private drains and building sewers shall be borne by the owner of the premises served by the same. Additionally, all cleaning of, repairs to or renewals of such drains and sewers shall be made at the expense of the owner of the premises served by such sewer and drain, provided that any labor on such a drain or sewer which may be required as a result of defects or obstructions in the main drain or public sewer shall be paid for by the City.
Whenever a betterment for a public drain or public sewer constructed pursuant to an order of the City Council has been assessed on the premises with respect to which an application for connection has been made and such assessment has been paid, no fee shall be be paid for entry into such public drain or public sewer, except as provided in Chapter 202, Streets and Sidewalks, §§ 202-10 and 202-12.

[1]
Editor's Note: Appendix B-2 is on file at the office of the City Clerk.
Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer.
No person shall make connection of roof downspouts, foundation drains, areaway drains or other source 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.
[Amended 5-21-2012 by Ord. No. 2012-158]
Except by special consent of the City Engineer, no private drain larger than eight inches in diameter or which is constructed of material other than vitrified, transite or iron pipe of an approved weight will be allowed to connect with any public drain. All private drains shall be laid accurately to straight lines and grades. When angles are unavoidable, the changes in direction shall be made by Y branches and bends. The opening in the Y in the direct line of the pipe shall be sealed and left unused for the purpose of flushing and cleaning.
[Added 4-7-2008 by Ord. No. 08-129]
A. 
Any land alteration, including but not limited to any excavation, paving, curb cutting, street opening, or any activity that will alter the drainage characteristics of a parcel of land that is greater than one acre, shall obtain a permit from the Department.
B. 
Application.
(1) 
The applicant shall file a completed application package. While the applicant may be a representative, the permittee must be the owner of the site or holder of an easement. The application package shall include:
(a) 
A completed application form with original signatures of all owners.
(b) 
A stormwater management plan and project description.
(c) 
Operation and maintenance plan.
(d) 
Erosion and sediment control plan.
(2) 
Filing an application for a permit grants the Department, or its agent, permission to enter the site to verify the information in the application and to inspect for compliance after issuance of the permit.
C. 
Performance criteria.
(1) 
At a minimum, projects shall comply with the policy, criteria, and information, including specifications and standards, of the latest edition of the Massachusetts Stormwater Management Policy Handbooks.
(2) 
The applicant shall prepare and implement an erosion and sedimentation control plan to prevent the introduction of sediments into the Department's sewers and storm drains. The design of any facilities required pursuant to this section shall be subject to the approval of the Department, and the design, installation and maintenance of such facilities shall be at the facility owner's expense. The Department shall have the right to inspect such facilities.
(3) 
The applicant shall submit to the Department a description of all new best management practices, including location, design and installation plans, vendor and manufacturer, and maintenance requirements.
(4)

The operation and maintenance plan shall remain on file with the Department and shall be an ongoing requirement.
D. 
The Public Works Department shall, from time to time, establish standard requirements or specifications to regulate the terms, conditions, definitions, enforcement, fees, procedures, and administration of this section.
[Added 6-16-2016 by Ord. No. 2016-200]
A. 
Any person or entity changing, altering, repairing, adding to or improving his/her or its property in any way that may or should impact the sewer system within the City of Melrose, or any person or entity proposing to add additional wastewater to an existing sewer connection, or any applicant for a new building permit, shall be required to mitigate infiltration/inflow sources which add extraneous water to the sewer system, thereby reducing its capacity and capability to accommodate new flows, at a rate of one gallon of infiltration/inflow removal for each additional gallon of wastewater that will be discharged to the sewer system as a result of the subject project. In the event a connection is subject to a state sewer connection/extension permit under Code of Massachusetts Regulations Chapter 314, and such permit is conditioned upon the completion of removal of infiltration/inflow prior to connection, said removal of infiltration/inflow shall be credited toward complying with the requirements of this section.
B. 
Title 5 (310 CMR 15) shall be used to determine flow rates, which will be used to calculate the value of the infiltration and inflow mitigation fee. Said fee shall be calculated based on the net change in Title 5 flows resulting from the subject project and a cost of $6.89 per gallon per day (gpd) of flow. Existing conditions will be established based on records of the Melrose Assessor's office. For example, a project with a net increase of five bedrooms compared to existing conditions per Assessor's records has an associated Title 5 flow increase of 550 gpd; therefore the fee for this connection is $3,789.50 (550 gpd net increase x $6.89/gpd). This is a one-time fee required prior to the issuance of a building permit or any other permit, order or permission for any change, alteration, repair, addition or modifications improving the subject property.
C. 
The fee assessment, or indication that no fee is required based on a determination of no net increase to sewer flows from the subject project, shall be determined by the Director of Public Works. The Director will not sign off on occupancy for any project for which an outstanding payment is due for any assessed infiltration and inflow mitigation fee, for the subject project or for any other project for which occupancy is sought by the same applicant.
D. 
For purposes of this section the following terms shall have the meanings set forth herein:
DIRECTOR
The Director of Public Works, after review, approval and consent by and of the City Engineer.
