(d) In order to provide for the collection and enforcement of its fees, rates, rents, assessments and other charges, the commission is hereby granted all the powers and privileges with respect to such collection and enforcement held by the municipality on the effective date of this chapter or as otherwise provided in this chapter. Without limiting the generality of the foregoing, the commission shall have the benefit, without further acceptance of sections forty-two A to forty-two F, inclusive, of chapter forty or filing of any certificate relating thereto, of liens for unpaid fees, rates, rents, assessments and other charges as provided in sections forty-two A and forty-two B of said chapter forty and sections sixteen A and sixteen B of chapter eighty-three, to the extent applicable and consistent with this chapter. With respect to any fees, rates, rents, assessments or other charges which remain unpaid for more than six months after the same shall have come due, the commission may, in addition to other remedies and actions available to it, issue a demand in accordance with section sixteen of chapter sixty and may collect such fees, rates, rents, assessments and other charges by means of remedies and procedures, to the extent applicable and consistent with this chapter, provided in sections twenty-four to one hundred and five, inclusive, of said chapter sixty; provided, however, that any lien or taking of property, or foreclosure of the right of redemption undertaken pursuant to this section shall be subordinated only to a municipality's lien on the property, and shall not interfere with any tax sale, distraint, taking or foreclosure of the right of redemption or other remedy exercised by the municipality, regardless of when the municipality's lien arose. If such demand is made within the time specified in section forty-two B of chapter forty and section sixteen B of chapter eighty-three during which liens arising thereunder remain in effect, said liens shall continue in effect for the period specified in section thirty-seven of chapter sixty, provided, however, that the year of assessment shall be deemed to be the year in which such demand is made. From and after the date of such demand interest shall accrue on unpaid fees, rates, rents, assessments and other charges at the rate specified in section fifty-seven of chapter fifty-nine. Applications for abatements in accordance with section forty-two E of said chapter forty and section sixteen E of chapter eighty-three shall be made within thirty days after the date of such demand. Upon written application the commission shall issue lien certificates in accordance with section twenty-three of said chapter sixty. No recordation of certificates issued by the municipality pursuant to said section twenty-three of said chapter sixty shall affect liens for the unpaid fees, rates, rents, assessments, and other charges of the commission. The commission shall be entitled to receive fees for collection in accordance with section fifteen of said chapter sixty. For purposes of the sections referred to in this paragraph, the terms city, town, water district, assessors, collector, clerk, treasurer, or commissioner as used therein shall mean the commission and the term tax or taxed shall mean the unpaid fees, rents, assessments, and other charges of the commission. The commission shall also have the powers and may exercise the remedies, to the extent consistent with this chapter, provided in sections twenty-nine, thirty-five and fifty and sections fifty-three to sixty-four, inclusive, of chapter sixty-two C and in chapter eighty and chapter eighty A. For purposes of said sections of said chapter sixty-two C, the terms commonwealth and commissioner used therein shall mean the commission. In addition to the other enforcement powers and remedies provided in this chapter, if any fees, rates, rents, assessments or other charges billed by the commission against any premises which are connected with the water works system or sewer works system remain unpaid for a period of more than sixty days from the due date thereof, and following such period notice and demand have been posted on such premises and have been given to the owner of said premises, by registered or certified mail addressed to said premises and to the address of said owner as shown on the records of the assessor of the city or town and to occupants of said premises by mail, to pay the same within fifteen days from the date of mailing of said notice, and such fees, rates, rents, assessments or other charges remain unpaid, the commission shall have the power and is hereby authorized to shut off the supply of water to said premises until said fees, rates, rents, assessments or other charges are paid, together with interest thereon at the applicable rate and the standard charge of the commission for restoring water service to said premises.
The commission may enter into an agreement with the municipality to provide collection services with respect to any of its unpaid fees, rates, rents, assessments and other charges, and if so, the municipal collector or treasurer shall disburse the amounts collected as provided in the agreement, but not later than 30 days after collection.
