WATER RESOURCES

Tectonic provides services for both public and private water resource projects. Having in-house capabilities in the areas of hydrogeology, hydrology, hydraulics, geotechnical and environmental engineering and regulatory permitting, Tectonic can provide municipalities and land development companies with the following services related to supply, distribution and storage of potable water

Tectonic personnel have been practicing dam engineering for over 30 years and have participated in the re-emphasis on dam safety as a national issue since the inaugural National Dam Inspection Program in the late 1970’s. We have participated in national dam safety organizations and have published papers and given presentations on a wide variety of timely dam safety topics. Dam engineering is, and has been, a principal service for the firm. We are familiar with regulatory protocols, the state of the practice, new technologies and current trends through on-going projects, seminar and conference participation. Tectonic offers a full range of dam engineering services including:

  • Bathymetric and land surveying
  • Conceptual, preliminary and final design
  • Dam break analysis
  • Dam safety inspections
  • Embankment stability analyses
  • Emergency Action Plans
  • Geotechnical and geologic investigations
  • Gravity dam stability analyses
  • Hydraulic modeling of reservoirs, spillways and downstream channels
  • Hydrologic watershed modeling
  • Inundation mapping
  • Construction administration

Tectonic uses a variety of techniques to develop economic solutions for the remediation of existing dams to meet regulatory dam safety standards such as:

  • Earth stabilizing berms
  • Embankment blanket and toe drain systems
  • Foundation grouting
  • Ogee, labyrinth and gated crest spillways
  • Post-tensioned strengthening of gravity structures
  • Reservoir intake/outlet facilities
  • Roller compacted concrete spillways and overlays
  • Stilling basins and energy dissipaters

States and local municipalities generally require that the quantity and quality of stormwater runoff from development or construction should be improved (or at least not altered) from the current conditions. As a result, project development almost universally has stormwater implications. Stormwater management facility planning, design, permitting, and inspection is a core competency of our Firm. Our teams have designed stormwater systems to service projects ranging across a broad spectrum of sectors including land development, transportation, recreation, facility expansion, utilities and energy. Tectonic has the experienced staff and state of the art resources to design on-site stormwater management facilities that can be cost effectively constructed and maintained. Tectonic considers and evaluates a wide variety of options in order to produce a design that maintains the project’s end user focus while satisfying the regulatory requirements in an efficient manner. Consideration is given to:

  • Green Infrastructure planning and LEED credits
  • Integration of stormwater management with the project program
  • Disconnected practices to reduce peak flow impacts
  • Compatible facility location and geometry
  • Site safety and liability concerns
  • Regionalization and master planning
  • Harmonious and native species landscaping
  • Proprietary stormwater treatment practice usages
  • Innovative site planning techniques
  • Jurisdictional requirements or standards

Presently the responsibility to design and build on-site facilities to meet these requirements generally lies with the project owner. As regional drainage agencies and local communities implement inter-municipal and/or watershed-wide storm water management plans, the project owner’s burden will shift from constructing theses facilities on-site to paying a fair share of the cost for regional or watershed-wide facilities. Tectonic can also assist with the Owner’s assessment of the implications of participating in a regional system.

Having in-house capabilities in the areas of hydrogeology, hydrology, hydraulics, geotechnical and environmental engineering and regulatory permitting, Tectonic can provide municipalities and land development companies with the following services related to supply, distribution and storage of potable water.

  • Distribution Main Design and Rehabilitation
  • Groundwater Supply Well Design
  • Pump Station Design
  • Source Water Feasibility Studies
  • Surface Water Reservoir Design
  • Storage Tank Design and Rehabilitation

Whether it be an aging sanitary sewer system or a need to create a new sanitary sewer district or new collection and pumping infrastructure, Tectonic is prepared to take on the challenge. Our approach to a sewer rehabilitation project is to perform a thorough condition assessment, evaluate all repair and/or replacement options and prioritize recommendations to allow an owner to plan projects within its financial capabilities. New infrastructure is designed using a similar approach and all projects are designed to minimize impacts to adjoining residential and commercial properties. Services provided in this area of expertise include:

  • Collection Main Design
  • Pump Station and Force Main Design
  • Collection Main Condition Evaluation
  • Infiltration and In-flow Analysis
  • Trenchless Rehabilitation Evaluation
