- Planning and Research
Planning and Research
GD&F's planning experience includes regional planning documents, system master plans, capital project programming, preliminary engineering design and financial reports. GD&F's service-oriented team is sensitive to function and practicality.
GD&F applies time-tested research methods to optimize project function, affordability and performance. GD&F examines the effects of future regulations, economic constraints and new technologies with computer modeling to define trends and correlate system data. - Resources
Resources
Known for technological leadership and innovation, GD&F has the proven expertise to develop water supplies and protect water resources. Our design experience encompasses watershed protection, dams and reservoirs, well fields and river intakes.
GD&F is a leader in dam engineering and our work has received national recognition. GD&F's environmental and geo-scientists have also developed hundreds of groundwater supplies. - Treatment
Treatment
GD&F understands the current regulatory environment and the need for creativity and flexibility in treatment plant operation and design. To achieve compliance, we effectively use new "multiple barrier" technologies such as membrane filtration, ultraviolet disinfection, ozonation, and enhanced coagulation.
GD&F is a leader in membrane filtration system design. We have extensive project experience with microfiltration, ultrafiltration, nanofiltration and reverse osmosis applications using cartridge, high pressure and submerged systems. - Transmission
Transmission
GD&F's knowledge of water transmission systems is unmatched. We have designed all types of pumping applications for large regional water works as well as small community systems. We also have practical, hands-on experience with pump hydraulics and controls.
GD&F has designed many transmission projects using computer modeling methods with flow calibration. We also offer such services as pressure and capacity analysis, leak detection and lost-water control. - Storage
Storage
The health and safety of water storage facilities have come under ever increasing scrutiny by regulators. Water age, mixing and circulation have a definite effect on water quality. The integrity and security of storage tanks are no longer afterthoughts in today's world.
GD&F has designed storage tanks in all hydraulic settings and configurations (standpipes, spheroids, ground-level, reservoirs, pillar/pedestal and clearwells) in the full range of materials. - Distribution
Distribution
The distribution of water - meeting the demands of all customers at all times - is a never-ending challenge for the water industry. GD&F has met these demands with effective design and engineering.
GD&F has designed distribution systems for every application and service environment. We have knowledge of materials, new technologies and advanced design. We use computer modeling to determine such community needs as fire protection, metering, leak prevention and system reliability. - System Management
System Management
GD&F's licensed operators have hands-on experience in running, repairing and optimizing water systems and treatment plants. They are fully trained in plant operations, such as filter performance, CT, corrosion control and coagulation optimization.
GD&F provides client assistance, ranging from water rates and system administration to financial studies and system appraisals and valuations.
