The Portsmouth and Pease drinking water systems continue to experience high demand in both systems due to irrigation and cooling system usage. In the last month the combined system demands have averaged 5.4 million gallons a day. Fortunately, water levels in both the City's reservoir and groundwater sources are holding up and system operators are managing the system such that water supplies are meeting these demands.

As the Department of Public Works continues to keep City property clear of obstructions and its lawns and gardens trimmed, the Parks & Greenery Department asks for residents help in keeping sidewalks and roadway sight lines clear.

Private property owners are required by City ordinance to keep the plants and shrubs on their property trimmed so as not to interfere with or obscure public property. This means keeping hedges bordering sidewalks and plants that might obstruct visibility at driveway and road intersections trimmed back. 

The City Water Department has published the Water Supply Report for the Second Quarter of 2024. Leading the report is detailed information regarding the fact that the Portsmouth and Pease drinking water systems are currently experiencing very high demands in the system due to irrigation and cooling system demands.
