and Information About York's Rivers, Maine > Water Supplies
upper reaches of the York River watershed are unique in that not
only York, but surrounding towns, rely on these ponds and reservoirs
as public water supplies. As a result, within Southern Maine, this
upland area represents a large area of land that needs to be protected
from a human point of view, as well as for benefits to wildlife
and the river.
new areas of York are developed, availability of town water and
sewer lines limits development. A more detailed analysis of
the soils and suitability is provided in the Radcliffe Study (see
General Studies, G2).
reservoirs provide high quality water to the local towns, and the
York sewer district is in compliance with state and federal regulations.
What is unknown is how the use of these ponds for reservoirs might
be affecting instream aquatic habitat, including water quantity
over summer months. This has not been expressed as a strong
local concern, however.
Water District has been working for 20 years on land aquisition and
watershed management for Chase's Pond. Management plan for the Chase
Pond watershed (2694 acres), of which about half is owned by the York
Water District. This pond is in the Cape Neddick River watershed.
The plan includes:
Potential sources of pollution (including parking lots, abandoned
vehicles, houses and farm animals)
Emergency management to protect the public water supply
Woodlot management plan for the water district property
Wildlife habitat enhancement plan

annual report on water quality includes data on possible contaminants
in the York Water Supply. According to the Water District,
all of these parameters are very low, well below EPA minimum levels.
Water District has been in existence since 1896, and has used
Chase's Pond as the sole source of water since then. The
Water District built a filtration plant in 1990. More information
about the plant is available on the District's web page.
York Sewer District does not discharge into the York River, but
the Sewer District is still relevant to the watershed. As
the sewer lines are extended, this influences the pattern of development
in the watershed, which impacts habitat, recreational use, and
water quality, to name a few.
first secondary treatment plant was constructed in 1975, to handle
an average daily flow of 1.6 million gallons per day, and a peak
flow of 4.5 million gallons per day. The treatment facility
was designed to serve York for approximately 20 years: however,
due to the increased population growth of the 1980's, flows to
the facility had reached design levels by 1990.
1990, the York Sewer District, which owns and operates the treatment
facility, obtained the services of Wright- Pierce Engineers to
design an upgraded facility at the existing site. In 1994, the
new facility went on line, providing treatment for an average
of 3.0 mgd and a peak flow of 7.5 mgd.
