Twice-Weekly Sprinkler Irrigation Schedule

Twice-Weekly Irrigation FAQs

 Hingham, Hull and North Cohasset System
1. Why is Aquarion implementing water restriction measures?
Historically, when the demand for water increased in a community, the water industry considered only one solution: construct a new water supply (a well, a reservoir, or an interconnection with another community). Forward-thinking water utilities and community leaders have now come to recognize that prudent use of these precious resources is also part of the solution; in part, because spending money on new water supplies will result in higher water rates and conservation is simply better for the environment.
With this new approach, Aquarion, like many other environmentally conscious utilities, has begun implementing annual irrigation restrictions in some of the communities it serves in Massachusetts and Connecticut, including for the communities of Hingham, Hull, and north Cohasset.
Irrigation restrictions are just one of the solutions that the Company is implementing as part of its water resource management program. For its system serving Hingham, Hull, and north Cohasset, Aquarion is also evaluating adding to our water supply by implementing “flood skimming”. This process involves diverting excess water from Accord Brook and storing it in our existing kettle ponds and Fulling Mill Pond. This stored water would then be managed and released during periods of low stream flow in the summer to augment the flow of the Weir River. Aquarion is working closely with the Weir River Watershed Association and the Massachusetts Department of Environmental Protection (MassDEP) to evaluate whether this unique solution can provide both a benefit to the environment (in terms of healthy stream flows) while also allowing for increased withdrawals from our existing water supply sources located in the Weir River Watershed.
Through the Water Management Act, MassDEP regulates the amount of water that all water suppliers in Massachusetts can withdraw from the environment. Like all other water suppliers, Aquarion has an annual limit that it can withdraw from its sources. In recent years, Aquarion’s water withdrawals have been safely below this limit. Our customers’ commitment to these irrigation restrictions will help ensure that this positive trend continues.
2. Who regulates the amount of water that water utilities can withdraw from the environment? 
The Massachusetts Department of Environmental Protection (MassDEP) regulates and closely monitors the quantity of water that water utilities withdraw from the environment. 
3. When can I water my lawn? 
The water restrictions have been established pursuant to Aquarion’s Rules and Regulations, as approved by the Massachusetts Department of Public Utilities.  
Water restrictions are in effect from April 15 thru October 15. 
The restrictions apply only to irrigation systems and hose-end sprinklers. 
Customers with odd number street addresses may only water on Tuesdays and Saturdays, and those with even number street addresses may only water on Wednesdays and Sundays. 
On these assigned days, customers are allowed to water before 10 a.m. and after 6 p.m., when evaporation losses will be minimized and more water goes to the plants’ roots.
4. Is hand-held watering and drip irrigation allowed?
Yes, hand-held watering and drip irrigation are permitted at any time. 
5. Am I allowed to wash my vehicles or fill a swimming pool?
6. I use my own private well for irrigation; do these restrictions apply to me? 
No. The restrictions do not apply to irrigation systems that are supplied with water from a private well. 
7. Where can I find information on lawn and garden care? 
Visit for tips on lawn and garden care. According to Greenscapes:
Grass grows the deepest and healthiest roots with infrequent watering. 
Watering two days a week is more than adequate to have a beautiful lawn. In fact, research has shown that grass thrives with about an inch of rain a week - some supplied by Mother Nature and the rest by just one watering.
Additional Lawn IrrigationTips:
Set your mower at one of the higher cutting heights to help your lawn retain water. Keep your mower blades sharp. Dull blades tear grass and require it to use 40-60% more water to repair itself.
Mulch your lawn naturally by letting clippings remain on the lawn. This will help stop water loss.
Avoid over-watering by using a rain gauge to tell when your lawn needs water and also to measure how much you’re applying. Generally, turf grasses need about ¾"—1" of water per week. If the forecast calls for rain, hold off on watering.
Position your sprinklers to water only the lawn—not driveways, sidewalks, patios, or roads.
For irrigation systems: The sprinkler heads should be adjusted so the areas they water don’t overlap. Regularly inspect for leaks and repair them quickly. Equip the system with rain sensors so you don’t waste water by irrigating while it’s raining.
When planting new grass, use one of the new drought-resistant grasses.
8. Is our community doing anything new with respect to water conservation?
Yes, Aquarion has implemented a new water conservation program for our customers.  We are replacing toilets, shower heads, and faucet aerators for free.  In addition, we are offering a $250 rebate towards an energy efficient clothes water and $2,500 towards alternative landscaping costs for demolishing an automatic irrigation system.  To find out more information and if you are eligible for these benefits please visit our website:
