Where does Derry's water come from?

What is going on regarding the Manchester Water Works Water Treatment Plant renovations and how will this affect my water?
The Water Treatment Plant underwent a major renovation and process upgrade. Derry Core System customers will receive water which has been disinfected primarily with ozone instead of chlorine and that has been filtered by eight new, deep bed filters. This change will mean that your tap water will not have a noticeable smell of chlorine, taste better and be safer for you to drink. This work is completed.
Why will the water still contain low levels of chlorine?
Even with the use of ozone, federal regulations require that public water systems maintain a disinfectant throughout the entire piping network. MWW now uses a form of disinfectant called chloramine to meet this requirement.
Are there any restrictions on activities on Lake Massabesic?

What would cause a higher than normal water bill?
The most common cause of a high water bill is a toilet leak. These are not always easily detectable. Check the water level in the tank to make sure it is not dripping into the filler pipe. Another simple test is to add food coloring to the tank before going to bed at night. If in the morning the water in the bowl has turned to that color, then there is a leak.
Other causes of high usage could be leaks such as dripping faucets or a leaking irrigation pipe. Also, people tend to use more water during the warmer months for lawn and garden watering, car washing, filling pools, etc..

When do I call for a final water bill?
Call at least 2 business days before the closing date (or date that you want the final bill effective) to set an appointment to have the actual meter inside the property read. The bill will be ready on the same business day as the reading.
What information do I need for the final water bill?
In addition to the reading, The Town will need the new owner’s name, date of the closing and what needs to be done with the final bill (do you want it mailed, faxed or will it be picked up).
As a landlord, can I put a bill in a tenant’s name?
Yes. For residential property the bill can be put in “care of” the tenant. The tenant needs to come into the office to sign a Tenant Agreement form. The tenant also needs to provide proof they are living there (i.e., a lease or a letter from the owner saying you are responsible for the water bill). The next full bill will go to the tenant and there is a $1.00 charge that will be applied to each bill.
For commercial property, we will send the owner an authorization form. When the signed form is returned to us, we will change the bill in care of the tenant. Ultimately, however, an unpaid water bill is the responsibility of the property owner and is considered a lien on the property itself.
