Mandatory Outdoor Watering Ban, Effective August 1, 2022

Due to worsening drought conditions, low water pressure complaints, and the Energy and Environmental Affairs (EEA) Level 1 Drought declaration for the Cape Cod region, the Board of Water/Wastewater Commissioners at their July 27, 2022 meeting voted unanimously to implement a mandatory outdoor water ban effective August 1, 2022, until further notice, to help ensure an adequate water supply for fire protection and health and safety needs. 

As of August 24th, Cape Cod is now under Level 3 - Critical Drought.

*Hand watering is allowed between the hours of Midnight to 8am and 5pm to 9pm.

Exceptions to the restrictions include health and safety, agriculture and livestock, and core functions of a business, such as landscape nursery centers.

Private well users are also asked to voluntarily participate, as wells draw water from the same water source on Cape Cod.

Should restrictions change, notifications will be posted to the public. Further details are available on

Thank you for your cooperation.

Mandatory Water Restrictions, Effective May 11, 2022 through July 31, 2022

Outdoor water use is only allowed on Monday, Wednesday and Friday between the hours of midnight and 8am and 5pm to 9pm.  Hand watering is allowed as needed anytime.

Residents with Private Wells

Harwich Water respectfully asks everyone to help support our efforts in implementing this mandatory schedule to ensure the future health and adequacy of our water supply, including residents/businesses with private wells.

Our Acquifer

The Monomoy Lens, from which our groundwater is pumped, is recharged by precipitation events over the winter and early spring. The lack of precipitation has resulted in lower groundwater levels. With the warm summer months on the horizon, the ability for precipitation to recharge the aquifer will quickly diminish as most of the precipitation that occurs will be evaporated before entering the groundwater table.
