Newton Consultants, Inc. specializes in water supply,
water rights and water resources management programs. Services include
design of high-capacity water wells and engineering oversight during their
construction. Some example projects completed by Newton are summarized
Persimmon Residential Community & Golf Course
Newton evaluated feasibility of using ground water for irrigation purposes
since surface water was not available for this project near Gresham, OR.
Newton located and designed irrigation wells, dam and reservoir systems
to store the pumped ground water. Newton also assisted in obtaining the
required water rights from the Oregon Water Resources Department.
Eagle Crest Resort
Eagle Crest Resort needed additional water supply for a proposed expansion.
Newton investigated ground water availability and assisted with design
and construction oversight for a new high-capacity well capable of 1,500
gallons per minute. Newton also assisted with preparation of water right
permit applications for submittal to the Oregon Water Resources Department.
The permit was granted.
Newton performed a water availability study, assisted with well design
and construction, analyzed pump test data and prepared a ground water
permit application for an irrigation well to irrigate the golf course
at this resort in the Columbia River Gorge.
Deschutes Valley Water District
Newton was hired by the Deschutes Valley Water District to improve its
springwater collection system at Opal Springs on the Crooked River southwest
of Madras, OR. This spring and collection system provides potable water
for a 125-square-mile area. Newton conducted a hydrogeologic investigation
to identify the source of the spring, and recommended drilling test wells
to evaluate subsurface conditions. A 12-inch-diameter test well drilled
to a depth of 425 feet produces artesian flow in excess of 5,000 gallons
per minute under shut-in pressure of 48 pounds per square inch at the
well head. Newton and the District coordinated with the Oregon Water Resources
Department and the U.S. Geological Survey during the project since the
test wells provided significant data on Deschutes Basin hydrogeology.
Black Butte Ranch
Newton performed an investigation of hydraulic connection between a deep
aquifer proposed for water supply and the overlying aquifers. This work
determined that pumping the deep aquifer would have no significant impact
on the overlying aquifers and springs, nor would it interfere with water
rights held by other water users. Based on these findings, OWRD issued
a permit for groundwater use. Newton subsequently designed a well, prepared
construction specifications, assisted
with obtaining and reviewing bids, supervised well construction, and analyzed
pumping test results. The completed well is efficient and can produce
up to approximately 1,200 gpm.
Indian Meadows Water Company
The Indian Meadow Water Company needed to increase reliability of high-quality
water supply to its customers. Newton conducted evaluations of aquifer
systems at the site north of Sisters, OR, designed a new well, prepared
contract and bid documents, assisted with bid reviews and selection of
a contractor, provided oversight during well construction and well testing,
analyzed well test results and assisted with a water right transfer to
amend the existing water right by adding the new well as an authorized
point of ground water appropriation.
Crooked River Ranch
Newton performed a ground water availability investigation and estimated
the potential yield and depth for a new high-capacity well. Newton prepared
specifications and construction documents for the well, well piping, pump
and control systems, and assisted the Company in obtaining well construction
bids. Newton oversaw well construction and pumping tests, reviewed contractor
invoices and prepared construction reports. The well, which augments the
water supply for this 12,000-acre, 2,600-lot development, is over 800-feet
deep and yields 750 gpm.
Broken Top Residential Development & Golf Course
Newton performed a water availability study, designed a well, prepared
construction specifications and analyzed pumping test data for a 350-feet-deep,
800-gpm irrigation well.
Mt. Hood, Oregon
Resort on the Mountain
The Resort needed additional water for golf course irrigation. The nearby
Sandy and Salmon Rivers are protected as wild and scenic rivers, and additional
water rights from the rivers were not available. The Resort retained Newton
to determine the feasibility of using ground water for irrigation. The
estimated demand required pumping 800 to 1,000 gpm from three to four
wells. Newton evaluated the basin and determined that storage and recharge
of groundwater was adequate. The OWRD had concerns that pumping high-yield
irrigation wells could deplete the Salmon or Sandy Rivers according to
OAR 690-09. Based on this concern, Newton evaluated pumping impacts on
the rivers using a MODFLOW computer model and concluded that depletion
would be within OWRD’s acceptable limits. Newton designed test and
production wells; supervised their construction; organized, directed and
analyzed pumping test results; prepared reports to the OWRD; and assisted
the Resort in successfully obtaining a ground water permit for golf course
Marrow County, Oregon
Finley Butte Regional Landfill
Newton investigated and characterized geology and groundwater conditions
in the Juniper Creek, Sand Hollow and Butter Creek area of Morrow County
to satisfy DEQ permit requirements for the new 800-acre Finley Buttes
Regional Landfill site. This work involved drilling and sampling to identify
sedimentary and basalt (Columbia River Basalt Group) formations, and conducting
pumping tests to quantify the characteristics of the basalt aquifers.
Newton designed a 400-feet-deep water-supply well with a deep-well turbine
pump and masonry block well house. The water-supply design work included
all electrical, structural, building details and mechanical systems. Three
monitoring wells with well houses were also designed and installed to
allow water quality sampling. This sampling, which is a regulatory requirement,
is intended to confirm that groundwater was not being contaminated by
the landfill or related site operations. Water quality testing was therefore
very important for this sensitive project. The project was privately funded
by Tidewater Barge Lines.
City of Garibaldi
Newton developed an investigation program to evaluate the potential hydraulic
connection between the aquifer used for municipal supplies and nearby
streams. The intent of the investigation was to evaluate whether the City’s
water-supply wells had significant impact on nearby streams (per Oregon
Administrative Rules Chapter 690, Division 9) and the feasibility of obtaining
additional groundwater rights for the City. Newton also assisted the City
in development of a wellhead protection program.
Mt. Angel, Oregon
City of Mt. Angel
The City was concerned about the ability of the basalt aquifers to provide
long-term municipal water supplies because of reported water-level declines
in area wells and related administrative actions implemented by the Oregon
Water Resources Department. These actions include the creation of the
Mt. Angel Groundwater Limited Area, which restricts use of the basalt
aquifers. As a consultant to Westech Engineering, Inc., Newton investigated
the long-term sustainability of aquifers supplying City wells and the
feasibility of short-term solutions such as the construction of new wells
and/or the purchase of existing private wells with water rights. In addition,
Newton reviewed the City's wellhead protection measures and developed
a plan that will enable the City to correct existing deficiencies and
comply with more stringent wellhead protection standards as they are implemented
in the future. Newton also provided the City with recommendations for
the rehabilitation of an existing well, and assisted Westech Engineering,
Inc. with the design, construction and production testing of a new well.
The well rehabilitation was the first Oregon trial of a new, innovative
method for restoring well production. Most of Newton’s work was
incorporated into an update of the City’s Master Water Plan.
