What is banned

Halifax Water mandatory Stage 1 restrictions apply to the Lake Major service area: Dartmouth, Cole Harbour, Westphal, North Preston, Eastern Passage, and the Burnside Industrial Park. Stage 1 prohibits: lawn and landscape automatic / hose-end sprinkler watering, vehicle washing at home, residential pool filling, and golf-course irrigation. Hand watering with a shut-off nozzle for trees, shrubs, vegetable gardens, and flower beds remains permitted any time. The restrictions have been in effect since September 10, 2025; Lake Major remains below seasonal normal as of mid-May 2026.

What is still allowed

💧 Hand watering

Hand watering with a shut-off nozzle is permitted any time for trees, shrubs, vegetable gardens, and flower beds. Lawn turf is not exempt - it cannot be irrigated under Stage 1.

🌿 Drip irrigation & soaker hoses

Permitted any time. Drip is exempt from sprinkler hour windows.

🥬 Vegetable gardens

Watering vegetable gardens by hand or drip is permitted at any time, even during the strictest stages.

🪣 Rain barrels

Rainwater collected on your own property is unrestricted and may be used at any time for any purpose.

Fines & enforcement

Bylaw enforcement under Halifax Water Drought Mitigation Plan

Halifax Water bylaw enforcement officers respond to complaints and patrol the Lake Major service area. First offences typically receive a warning; repeat violations escalate to fines. Stage 1 has been in effect since September 10, 2025 and was originally scheduled for review monthly based on reservoir recovery.

Effective: September 10, 2025

🏠 HOA / condo rules

Nova Scotia condominium corporations cannot enforce landscape rules that conflict with municipal water conservation measures. Under the Nova Scotia Condominium Act, common-element irrigation must follow Halifax Water Stage 1 prohibitions. Private-unit owners cannot be fined for brown or dormant lawns during active mandatory restrictions.

Why these restrictions exist in Dartmouth

Dartmouth (population ~107,000) and the eastern Halifax Regional Municipality communities of Cole Harbour, Westphal, North Preston, and Eastern Passage are served by Halifax Water from Lake Major, a reservoir in the Waverley area. Halifax Water declared mandatory Stage 1 water conservation measures for the Lake Major service area effective September 10, 2025, after the lake reached its warning phase under the Halifax Water Drought Mitigation Plan. The restrictions remain in effect as of mid-May 2026. Lake Major has been roughly a metre below seasonal normal at the time of declaration (per Halifax Water spokespeople), driven by the Atlantic Canada extended dry pattern through 2025 and a winter and spring that did not fully restore reservoir levels. Stage 1 prohibits: outdoor lawn and landscape automatic / hose-end sprinkler watering, vehicle washing at home, filling residential swimming pools, and golf-course irrigation. Hand watering with a shut-off nozzle remains permitted for trees, shrubs, vegetable gardens, and flower beds. The Pockwock Lake service area (Halifax peninsula and western HRM) remains on voluntary conservation - see the Halifax page for those rules. Both reservoirs are operated by the same utility (Halifax Water) but feed physically separate distribution systems; Stage status is independent per reservoir. Burnside Industrial Park, located in eastern Dartmouth, is the largest industrial park east of Montreal and the largest commercial water consumer in HRM. Industrial users in Burnside operate under separate commercial water accounts with their own conservation requirements layered on top of Stage 1. The Macdonald and MacKay bridges connect Dartmouth to the Halifax peninsula; the harbour itself is saltwater and is not a freshwater source. If Lake Major continues to decline, Halifax Water can escalate to Stage 2 (which would further restrict commercial and institutional use) and Stage 3 (emergency rationing). The current Stage 1 has held for over eight months and Halifax Water has not yet announced escalation as of mid-May 2026.

Supply: Lake Major roughly a metre below seasonal normal. Atlantic Canada extended dry pattern through 2025-2026 with insufficient winter and spring precipitation to restore reservoir storage.

How to keep your Dartmouth lawn alive

10 tips for Dartmouth homeowners.

Stage 1 prohibits all lawn watering: allow Kentucky Bluegrass and Tall Fescue to go fully dormant. Both survive 4-6 weeks of summer dormancy and recover with autumn rain.

Hand watering with a shut-off nozzle is permitted any time for trees, shrubs, vegetable gardens, and flower beds. Prioritise mature trees and food crops over ornamental beds.

Vehicle washing at home is prohibited under Stage 1. Use a commercial car wash that recycles water.

Filling residential swimming pools is prohibited. Top-offs may be permitted with permission from Halifax Water; verify before adding water.

Install a rain barrel: captured rainwater is unrestricted at every Halifax Water stage and is the most reliable source under mandatory Stage 1.

Mulch heavily (50-75 mm of wood chip or bark) around trees and shrubs to retain whatever moisture remains in clay-loam soils.

Cole Harbour, North Preston, Westphal, and Eastern Passage are all on Lake Major and follow the same Stage 1 rules.

Burnside Industrial Park employers operate under separate commercial accounts; industrial-process water rules are layered on Stage 1 residential rules.

Skip nitrogen fertiliser through summer. It forces growth that demands water the lawn cannot receive under Stage 1 prohibitions.

Monitor halifaxwater.ca/mandatory-water-conservation weekly. Stage 2 escalation would tighten commercial and institutional restrictions if Lake Major continues to decline.

Dartmouth water restriction FAQs

Is this Dartmouth, NS, or Dartmouth, MA / UK?
This page is Dartmouth, Nova Scotia (Halifax Regional Municipality, ~107,000 residents, served by Halifax Water from Lake Major). Dartmouth, Massachusetts (Bristol County, ~33,000 residents) is a coastal town near New Bedford with its own municipal water under Massachusetts state framework. Dartmouth, Devon, UK (~5,500 residents) is the original namesake port town on the River Dart in England with its own UK Environment Agency framework. Each has its own water utility under separate national / state / provincial frameworks. The mandatory Stage 1 restrictions described here apply only to Halifax Water customers serviced by Lake Major in HRM.
I'm in Cole Harbour / North Preston / Eastern Passage - does this apply to me?
Yes. The Lake Major service area covers Dartmouth, Cole Harbour, Westphal, North Preston, Eastern Passage, and the Burnside Industrial Park. All of these communities operate under the same mandatory Stage 1 restrictions: no lawn watering, no vehicle washing at home, no pool filling, no golf-course irrigation. Hand watering with a shut-off nozzle for trees, shrubs, vegetable gardens, and flower beds remains permitted.
I'm in Dartmouth Crossing / Burnside - am I a commercial consumer subject to industrial rules?
Residential customers in Dartmouth Crossing and the residential edges of the Burnside Industrial Park follow the same Stage 1 rules as elsewhere in the Lake Major service area. Commercial and industrial businesses operating from Burnside (the largest industrial park east of Montreal) have separate commercial water accounts with their own conservation requirements layered on top of Stage 1. Industrial process water rules are negotiated per-account with Halifax Water; landscape and lawn irrigation at industrial facilities follows the same Stage 1 prohibitions as residential customers.
Why is the Dartmouth side under mandatory Stage 1 but Halifax side may not be?
Pockwock Lake (Halifax peninsula and western HRM) and Lake Major (Dartmouth and eastern HRM) are physically separate reservoirs with independent storage and inflow conditions. Lake Major reached its warning phase first because of differences in catchment-area precipitation, draw rates, and seasonal recovery patterns between the two reservoirs. Halifax Water sets stage status independently per reservoir under its Drought Mitigation Plan. As of mid-May 2026, Lake Major remains at mandatory Stage 1 (since September 10, 2025) while Pockwock remains on voluntary conservation.
