Water filter service in Greenburgh, NY

What is in the water in Greenburgh

Greenburgh is served by Greenburgh Consolidated Water District No. 1 .

Source water: The district buys all of its water from the New York City Department of Environmental Protection through the Catskill and Delaware aqueducts, from protected watershed land about 120 miles to the north west. It serves roughly 40,000 people and is overseen by the Westchester County Health Department's Bureau of Environmental Quality rather than directly by the state. The water quality is high enough to hold a filtration avoidance waiver from the Environmental Protection Agency, which New York City attributes to the 1.5 billion dollars it has put into watershed protection programmes. Reported by Greenburgh Consolidated Water District No. 1 for 2023.

Filtration avoidance is the fact to sit with, because the phrase is easy to read as a technicality and it is not. It means this water is not filtered at any plant anywhere before it reaches Greenburgh. It is protected at source and it is disinfected, and it is genuinely clean, but nothing in the chain strains it. Two consequences follow at the house. Any particulate arriving at a fixture entered through the distribution mains or the building's own pipework, since there is no plant filter upstream that could have failed. And the usual reason to fit whole house filtration, correcting something the utility left in, does not apply here; the honest use for a sediment stage on this supply is protecting downstream equipment from mains debris after a repair.

These figures describe the distribution system. Your own tap can differ, and for lead it very likely does.

We do not yet hold a sourced figure for every field on this page. Where something is missing it is left blank rather than estimated, because an unsourced number here would look like information.

Buildings and plumbing in Greenburgh

The district publishes its own service line material inventory, which is unusual for a purchaser of this size and is the document to read before spending anything. Purchased unfiltered surface water carries no lead of its own, so whatever appears at a Greenburgh tap was picked up between the district boundary and the glass. That splits the question into two answerable parts. The first is the run of pipe from the main to the building, which the inventory records. The second is everything inside the building, which no inventory covers and which in practice means the solder on joints laid before 1986 and any brass fitting predating the 2011 change to the lead free definition. Householders reliably investigate the first and ignore the second, and in a house whose service line is already copper the second is the only part left.

What this means in practice

• Chlorine and chloramine taste. Confirm with free and total chlorine test strip, plus the utility report for the disinfectant type.
• Lead in drinking water. Confirm with certified laboratory analysis of a first-draw tap sample.

What these figures mean for filter choice

Lead is a plumbing question rather than a supply question in Greenburgh, as it is everywhere. What that means practically is that a filter certified under NSF/ANSI 53 for lead at the tap you drink from sits downstream of the entire problem, whereas a whole-house filter at the point of entry sits upstream of nearly all of it and costs several times more.

Filters that apply here

• Lead reduction filters. Point-of-use filters certified for lead under NSF/ANSI 53.
• Under-sink carbon filters. A carbon block cartridge on the cold line under the sink.
• Reverse osmosis, tank. A membrane system under the sink that produces treated water to a dedicated tap and stores it in a small pressure tank.
• Whole-house filtration. A filter plumbed into the main line where water enters the building, so every tap, shower, and appliance downstream is fed treated water.
• Sediment filters. A mechanical filter that captures sand, silt, rust flakes, and other particles.

Installation in Greenburgh

• Free water testing. Typically 45 to 60 minutes.
• Whole-house filter installation. Typically 3 to 5 hours.
• Under-sink reverse osmosis installation. Typically 2 to 4 hours.
• Repair, any brand. Typically 1 to 3 hours.
