Water Resource Services
Human activities interact with our natural hydrologic environment
in many ways. As water demand grows, the need for effective management and efficient use is greater.
The CES approach to water resource management challenges is to use science and engineering to create
solutions that leverage natural site features to reduce cost and improve water quality. Our services
Irrigation and Pumping System Design
CES has designed irrigation projects focused on water conservation throughout
the world. We have converted tens of thousands of acres from flood irrigation to many types of much more
efficient mechanized irrigation, resulting in water conservation many times on the order of 50%. Our
extensive experience with canal distribution systems, piping, and seepage issues has helped farmers get
more of their water where they need it. Our focus is replacing surface water discharges with land based
systems to improve instream water quality and replacing surface withdrawals with other sources to increase
Dam Repair and Removal
CES takes pride in assessing and upgrading how our community infrastructure
interacts with the natural environment. Our engineers and sub-consultants are experienced working with
existing earthen or concrete dams and the design of new water control structures. CES’ engineering team
is registered in nine states, and also provides geotechnical, hydraulic, environmental, and project
management services. Our approach focuses on whole-system, sustainable solutions, working with a site’s
natural attributes, the local landowners, and the needs of aquatic species, to achieve a lasting solution
which meets regulatory requirements and is in balance with the natural environment.
Fish Screen Design and Permitting
Irrigation diversions and road culverts often cause fish passage and screening problems. CES and
its associates have been providing solutions to these problems for over 20 years. CES and its
associates have extensive experience in design and installation of fish screening systems using
pressure backwash, gang wipers, channel bottom flat plates or combinations of these. Our design
and installation experience in fish passage systems include fish ladders such as Alaska Steeppass,
Denil and pool and weir structures.
Water Supply and Treatment
CES engineers, geologists, and hydrologists provide comprehensive water
supply and drinking water services. Our professional geologists can design, permit and oversee your
supply well installation to tap the best water bearing zones, considering quality and yield. Our civil
and mechanical engineers offer extensive experience with water pumping, piping and delivery systems, and
can certify your plans and document construction. If you need to improve or change water quality, our
chemical engineers have the experience from arsenic to reverse osmosis to disinfection treatment systems.
CES also offers complete design-build services for your water supply and drinking water needs.
Streambank Protection and Stabilization
Rapid changes in watersheds are often due to a combination of many factors. These include increased
runoff and sediment loading related to land use changes, differing stream alignment due to construction
or someone else's stream stabilization, damaged riparian buffer zones, manipulation within the channel
or a combination of these factors.
Sound, effective stream restoration requires attention to engineering, biology and social concerns and
issues. CES and its associates have designed and have overseen construction of over 10 miles of
streambank restoration. These projects have involved restoration systems that use combinations of
vegetation, wood and rock. These projects have been shown to withstand high-energy flows while
providing shade, structure and other aquatic benefits.
CES has over 30 years of wetland mitigation experience, including restoration,
creation, and enhancement design. Human needs have become more and more intertwined and reliant on our natural
watersheds over the years. This is a critical component in understanding a watershed and how conditions can
be improved. Our work starts with watershed delineation and assessment. From there our team assists with
projects involving upland water movement, open-channel flow, temperature assessment and reduction, lagoon
design, watershed management, and unsaturated zone water flow.
CES can assist you with all aspects of surface and groundwater water rights.
Water projects need confirmed water rights before project design, property transfer or construction of new
systems. CES has assisted private, municipal, industrial, and watershed councils with water right services
from dam removal to supply well installation to surface water withdrawals.
Wetland Delineations and Mitigation
We offer cost-effective, timely services for identifying and
delineating wetlands utilizing state and federal regulations. CES has constructed wetlands, lagoons,
and bioretention swales throughout the U.S. These features are often designed to treat wastewater or
stormwater runoff prior to flowing into streams and rivers. We have worked closely with local, state,
and federal governments in conjunction with private entities to delineate, mitigate, design, permit,
and construct wetland systems. We have successfully worked with many stakeholders with different
interests and views to reach a common goal.
