Manchester Water Works Recipient of Awards at the New England Water Works Association Annual Conference

Published: 09/14/2021 4:50 PM

Manchester Water Works (MWW) was the recent recipient of three awards given out this year at the New England Water Works Association (NEWWA) Annual Conference.

MWW was awarded Utility of the Year for large utilities that serve greater than 50,000 people. The award was given for “MWW’s significant improvements to the water system infrastructure, customer service, staff training, and operations to further protect public health of the customers it serves.”

The award highlighted MWW’s continuing improvements to its system’s infrastructure and service to its customers noting the upgrades of Cohas and Oak Hill Pump Stations; construction of three water storage tanks on Mammoth Road and Josephine Drive (Londonderry); construction of the radial collector well on the Merrimack River and the beginning of construction of a 7.2 MG Water Treatment Plant on Kimball Road in Hooksett. Also noted was the recent signing of the Southern New Hampshire Interconnection Water Agreement with six towns and water systems south of Derry to bring water as far as Plaistow.   

Power and Process Controls Manager Roger Gagnon was recipient of the Operator’s Meritorious Service Award given annually in recognition of special performance for continuous compliance with public health standards, consistent and outstanding contribution to plant maintenance, the development of new and/or modified equipment or significant process modifications to provide for more efficient and/or effective treatment, special efforts in the training of treatment plant operators and consistent and outstanding contribution to operation and/or maintenance of pump stations and reservoirs. Roger Gagnon’s dedication to Manchester Water Works since 1991 has been instrumental in keeping our Lakeshore Road Water Treatment Plant functioning at a nationally recognized high level.

MWW also received New England’s Best Tasting Water Award. Three independent judges taste “blind” water samples and collaborate to determine the winner who is automatically entered into the national Best Tasting Water contest held at the American Water Works Annual Conference and Exposition (AWWA ACE22) in San Antonio, Texas in June 2022.  MWW is excited to win this regional contest once again and for the opportunity to compete nationally at ACE22!

Manchester Water Works did not expand and thrive over the past 150 years without outstanding contributions from dedicated and talented individuals. Throughout the generations of Mayors, Aldermen, Board Commissioners, Directors, Consultants and most importantly the hundreds of employees over the past eight generations, the men and women who physically built, maintained and made the water “work” for the safety and health of our community. For their contributions and dedication, MWW will always be proud and thankful.

Manchester Water Works thanks all of our Manchester and out-of-town customers for your continuing support in allowing us to serve you and helping to maintain our valued water resource.

MWW Water Main Flushing Program will occur in May and June 2021

Published: 05/03/2021 1:06 PM



On Sunday, May 16th, 2021, the Manchester Water Works will begin an estimated six-week long program to flush 500 miles of water mains within the Manchester Water Works’ water distribution system.    The program will be conducted by Manchester Water Works’ employees between the hours of 10:00 p.m. and 6:00 a.m., Sunday through Thursday, in order to minimize the inconvenience to customers. Guy Chabot, Manchester Water Works Deputy Director, indicated that this is a biennial program to help improve water quality to our customers.

The flushing program will generally progress starting at the Water Treatment Plant in east Manchester, westerly across the city and portions of the surrounding towns which Manchester Water Works serves. Heavy commercial users will be notified by the Manchester Water Works prior to work being done in their immediate area.  Chabot asked that residential customers with special needs, such as in-house dialysis equipment, call the department to make their locations known so that they may also be notified in advance.

Customers may experience a slight discoloration of water during the flushing program due to the increased velocity of the water in the pipelines. Chabot indicated that he regrets that the program may inconvenience some customers, but that it is a necessary part of the departments’ preventive maintenance program. Customers experiencing prolonged or excessive discoloration are asked to call the department after allowing ten to fifteen minutes to flush their own service lines.

Any customers with questions regarding the program are also asked to contact the Manchester Water Works at 603-792-2808.

Water Works to Resume Collections

Published: 09/29/2020 9:52 AM

On June 30th, Governor Sununu issued Emergency Order #58 which succeeded Emergency Order #3 effective July 15th.  Emergency Order #3 says in pertinent part that the municipal utilities may begin non-payment collection proceedings on and after July 15, 2020 subject to the following provisions:

  • If a customer of municipal utility had an arrearage that accumulated between March 17, 2020 and July 15, 2020, before the municipal utility disconnects that service due to non-payment for that period of time the utility must first offer the customer an opportunity to make a reasonable payment arrangement over no less than six months, and for that payment arrangement, for that period of time, the utility cannot charge any fees for arrearages that accrued.
  • If a customer has an arrearage that accumulated before March 17, 2020, or after July 15, 2020, the utility’s normal collection and disconnect policy would apply.

Beginning October 1st, Manchester Water Works will resume disconnection notices on accounts with outstanding balances meeting the above state guidelines.  Our goal is to make contact with those customers who have outstanding balances and making a payment arrangement in accordance with the above.  If you currently have an outstanding balance and would like to arrange a payment plan, please call our office at 603-624-6494 (select option 3) to speak with one of our Customer Service Representatives. 

MWW appreciates that those who were economically impacted by COVID-19 may need an extended period of time to bring their account to current. Together, we will work towards a solution.  Our ultimate goal is to provide you and our community with potable water.

Fairhaven/Severance and Clair's Landing Boat Launches Closed

Published: 08/26/2020 8:43 AM

Fairhaven/Severance boat launch is always a shallow launch, and because the lake level is slightly lower than normal for this time of year, we have made the difficult decision to close the launch to trailers. Clair's Landing boat launch is also closed to boats and trailers.

Several trailers have become stuck in the water lately and we do not want to risk damage to people's boats or trailers by continuing to use this launch.

Canoes and kayaks can still be launched.

Thank you all for your understanding and cooperation!

Water Works COVID-19 Policies

Published: 07/22/2020 10:16 AM

All fees associated with paying your bill online or over the phone are being waived through August 31st.  All shut-offs for non-compliance or non-payment are suspended until further notice.


Our office is open to the public, but we do ask that you utilize online/phone payment options whenever possible to reduce traffic.


We are receiving questions about the delayed due dates on bills.  Due to the COVID-19 pandemic and the financial hardship that has resulted from it for many, Manchester Water Works and the Mayor determined we would not assess late fees until after August 4th.  In order to accommodate this, the due date for all bills was adjusted beginning in our mid-March billing.  As a result, there is no requirement to pay your bill before the due date indicated. 

Clarification has been requested - delaying payment until that due date does mean customers will receive another bill and have two quarterly bills due in the same month come the late summer or fall.  We do hope customers still pay their bills when they receive them if they are able to.  In addition, you can call our office and set up a payment arrangement if needed.  Any customer who has an autopayment set up with our office can call us to have the date adjusted.  

We understand this is new and different for us all, and we are happy to help answer any questions you may have.

Round the Res Tower Hill 5 Miler - Benefitting Water Youth Education Program

Published: 10/08/2019 8:37 AM

Saturday October 26th at 9:30am

Register by October 11th to get your race t-shirt!

Course is a gravel road and perfect for anyone interested in off-road/trail running.  No trail sneakers needed.  Maybe even some small/short rolling hills.  See course map at registration link below.


Proceeds of this race will be donated to the Manchester Water Works Youth Education Program. The Manchester Water Works Water Education program has been officially part of the Manchester School system curriculum since 1994. Each year we perform water related presentations in local classrooms, discussing the importance of water for each of us.  2019 marked a first for us and for Manchester; ALL 14 elementary schools are participating in some aspect of the program!  The 4th grade program includes classroom presentations and individual Water Science fairs! Individual fairs take place at each school with the City of Manchester Final at the Water Treatment Plant.  Finalists from the City Fair move on to the State of New Hampshire Water Festival and Water Science Fair Final.  Our 3rd grade program includes individual classroom presentations and our annual 3rd grade Poster Contest.  

The success of this program has been evident with our dealings with our customers over the years, and the program itself receives an abundance of positive feedback from children, parents, teachers and community members.  Generous community members volunteer their time to help judge all of these wonderful posters and projects. Not only are the students, teachers, and parents learning about various water topics, but also the people that volunteer their time to help facilitate the program. Promoting the education program allows the employees of Manchester Water Works to go out into the community and interact with our present and future customers.  Educating tomorrow’s consumers today is a proactive way to promote the Manchester Water Works’ goal of providing the highest quality drinking water to our customers.
