What is in the water in Bristol

Bristol is served by Bristol Water and Sewer Department .

Source water: A watershed of roughly 5,000 acres holding seven reservoirs, plus three well fields. Reservoir water collected in Burlington, Harwinton, Plymouth and Bristol is channelled through the Poland River into the transmission mains and on to the treatment plant. Five gravel packed wells produce over two million gallons a day and serve the low service area of the distribution system, and an interconnection with the New Britain Water Department supplements the Stevens Street area. The department has supplied the city since the early 1900s and tests for more than 83 contaminants. Reported by Bristol Water and Sewer Department for 2024.

The state source water assessment reaches a conclusion most people would guess backwards. It rates the reservoir system at low susceptibility to contamination and the well fields at high susceptibility. Groundwater is widely assumed to be the safer source, but these are gravel packed wells: shallow, sitting in permeable material, and open to whatever reaches the ground surface above them. A protected upland reservoir with a controlled watershed is the better protected of the two here. The practical consequence is that the answer to what treatment an address needs in Bristol depends on which half of the system serves it, and the low service area is the higher risk half.

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 Bristol

The Stevens Street area complicates a question that is otherwise simple. Water there is supplemented through an interconnection with New Britain, so part of Bristol is drinking another city's supply, treated under another city's corrosion control programme. Since corrosion control is what governs how much lead a given pipe releases, two identical houses in different parts of Bristol are not on the same footing. Establish which supply serves your address and whose inventory carries your service line record before deciding how to treat. Where the record shows lead, galvanised or unknown, a filter certified to NSF/ANSI 53 for lead at the kitchen tap covers the drinking water while the line is resolved.

What this means in practice

What these figures mean for filter choice

Lead is a plumbing question rather than a supply question in Bristol, 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.
