Main Break 10/30/15 - River Road

The water main at 95 River Road broke at approximately 9:20 on October 30th.  River Road from Fox Run Road to 68 River Road and all of Prospect Street will be without water service unti the main is repaired.  Water service should be restored by morning.

Some customers will have discolored water as a result of the main break.  Do not drink the discolored water (Manganese Advisory) and do not use any hot water until the cold water clears.

Single Family Residence Water Use Comparison

One of the common questions we receive is "How does my water use compare to the average home?".  Answering the question is not easy because volumes used by single family homes can vary over a wide range and depend on the number of occupants, water use habits, irrigation habits, etc. We analyzed the monthly water use records for the past 5 years for 1,582 single family home connected to our water system. The following table displays the results and attempts to give an idea of how water is used in the Town.

Water Commissioners

The Board of Water Commissioners is comprised of three elected officials serving staggered three-year terms.  Current members are:

Philip Knowles, Chairman

Richard Stone, Clerk

Mark Gallagher, Member

Overdue Accounts

If your bill is not paid by the due date then a notice will be sent to you concerning the late payment. Your balance may be subject to a late fee. If your bill is not paid within 30 days after the due date then a second notice will be mailed to you. You may be subject to another late fee and your water service may be terminated if the bill is not paid within ten business days.

Unpaid bills represent a lien on your property by the Town of Topsfield pursuant to the Massachusetts General Law GLC 40, Section 42A-42F.

Online Banking Systems

Customers that use online banking systems should send payments to the Town Collector, 8 West Common Street, Topsfield, MA 01983 rather than the Post Office Box listed on the return envelope. Online banking systems, except for the Town's Unibank system, do not issue payments electronically - the bank issues a printed check and mails it. Sometimes the check isn't mailed for several days.

The PO Box on the return envelope is actually a Century Bank automated lock box that processes payments based on information printed on the bill stub. If the scan line beneath the stub's mailing address is unreadable, or the stub is missing, then the lock box rejects the payment and forwards it to the Town Hall for manual processing.

In the event you need to make a payment to avoid a late penalty or termination of service, the safest thing to do is drop your payment off at the Town Hall. The Town Treasurer & Collector's Office hours are posted online and there is a drop box at the front door near the Town Clerks' Office that is checked daily. Late fees are typically calculated seven days after the due date to allow for any payments that might have been in transit near the due date.

Including the bill stub with your payment helps reduce our labor costs by reducing the number of hours spent processing and posting manual payments.

Help prevent cross connections

What is a cross connection? It's an actual or potential connection between a potable water line and any waste pipe, soil pipe, sewer, drain or other unapproved source. These connections pose a threat to public health by allowing contaminants to be siphoned or forced into the public drinking water system under certain hydraulic conditions.

In a residential setting, cross connections include submerged hoses, lawn irrigation systems, chemical spray applicators, connections to private wells, boilers, solar heating systems and fire sprinkler systems. These connections, if left unprotected, could introduce contaminants to the water system. Consumers play an important role in protecting public health by notifying the Water Department of any cross connections and helping to eliminate or properly protect the connection by installing a backflow prevention device.

Bill Frequency

Beginning in July 2008, the majority of our customers are billed on a quarterly basis. One third of our customers are billed each month to distribute the workload and cash flow as evenly as possible over the year. Each quarter contains 3 billing cycles. Cycle #1 customers are billed during the first month of the quarter - January, April, July and October. Cycle #2 customers are billed in February, May, August and November. Cycle #3 customers are billed in March, June, September and December.

We are happy to bill customers monthly if they wish. This is a popular option for some residents that participated in the monthly billing pilot study and with customers that want to monitor their water use and related expenses at a finer scale.

Why are backflow prevention devices tested?

Most backflow devices do not need to be tested or are not testable. However, two types of devices used to protect connections that pose the highest hazards need to be tested regularly.

Double Check Valve Assemblies (DCVA) are typically found on fire protection systems that are made of non-potable materials and have a fire truck connection. These devices prevent contaminated water from being drawn into the distribution system during main breaks or water being forced into the distribution system if the Fire Department uses the truck connection. DCVAs need to be tested on an annual basis.

Reduced Pressure Backflow Preventer (RP) are found on the highest hazard connections. These devices are designed to protect the water system even if part of the device fails. They are found on connections that a high risk such as chemical mixing tanks, heating systems containing chemical additives, fire protection systems with chemical additives and x-ray developers. RPs are tested once every six months.

Testing these devices ensures they are being maintained and in proper working order. The owner of the device has 14 days to repair or replace a device that has failed a test.

MassDEP Backflow Requirements

sinkWe are required to run a Cross Connection Control Program by the Massachusetts Department of Environmental Protection. DEP regulations, 310 CMR 22.22, along with the plumbing code govern cross connections.

According to DEP regulations, public water suppliers are required to:

  1. Control cross connections to the last free flowing outlet of the consumer.
  2. Have an approved Cross Connection Control Program (CCCP)
  3. Inspect all non-residential properties connected to the distribution system for cross connections.
  4. Maintain records including all correspondence, program plan, testing records, violation notices and other documents for inspection by DEP.
  5. Ensure all devices are tested by a DEP Certified Backflow Prevention Device Tester and all surveys are conducted by a DEP Certified Cross Connection Control Surveyor.
  6. Establishing a cross connection control program for residential customers including an educational component.
  7. Not allowing any cross connections in the system unless properly permitted and approved.
  8. Ensuring all double check valve assemblies and reduced pressure backflow preventers are tested according to schedule.
  9. Notifying owner's of the connections when they are in violation of the regulations.

Owners of the connections are required to:

  1. Notify the public water supplier of any connections protected by a double check valve assembly or reduced pressure backflow preventer.
  2. Make suitable arrangements so the devices can be inspected and tested during normal business hours.
  3. Maintain spare parts kits and any special tools needed to repair their devices.
  4. Overhaul, repair or replace any device that fails a test or is otherwise defective within 14 days of the initial inspection.
  5. Submit copies of inspection and maintenance forms to the water supplier.
  6. Maintain on premises testing records, approvals and other documents pertaining to the device(s).
  7. Make certain devices are tested according to DEP regulations or as required by the water supplier.

Local Permits

Prior to the creation of any cross connection or installation of a double check valve assembly or reduced pressure backflow preventer, the owner or their agent must file for a Cross Connection Permit. Click here to obtain the permit application form.

The permit will be reviewed to make sure the proper device is selected to protect the cross connection and that the proposed installation meets the requirements of 310 CMR 22.22. Applicants should take care to make sure all requirements are met otherwise the permit can not be issued.

Once the permit is approved and all other required permits have been obtained the applicant can proceed with installation of the device(s). Once installed the devices must be inspected and tested.

  • Cross Connection Control Program (Backflow)

    Welcome to our cross connection section. These connections are a specific class of connections to the distribution system that pose or could pose a health risk. Some of the more common cross connections in Topsfield include:

    • Filling a swimming pool with a garden hose while the end of the hose is below the flood rim of the pool.
    • Certain types of fire suppression systems.
    • Chemical mixing tanks.
    • Certain types of heating, ventilation and cooling systems.

    Cross connections are pathways that could introduce contamination to the water distribution system under certain hydraulic conditions. We are required by the Massachusetts Department of Environmental Protection to run a Cross Connection Control Program to make sure these connections are properly protected by a backflow prevention device or eliminated. Some devices require annual or semi-annual testing based on the degree of hazard and we are required to make sure tests are done according to MassDEP's schedule.

      The Water Management Act gives the Massachusetts Department of Environmental Protection the authority to regulate ground water and surface water withdrawals in excess of 0.100 million gallons per day (MGD). The Water Management Act was enacted during the 1980's and there were quite a few water suppliers that fell under the new regulations. The regulations created what is refered to as a "registration" volume which is the amount of water historically withdrawn by the supplier at the time DEP's regulation took affect. Some suppliers have filed for water management permits to allow withdrawals in excess of the registration volume. The Town of Topsfield currently has a registration volume of 0.430 MGD and a permitted volume of 0.170 MGD.
