Water Systems

Successful water, wastewater and storm drainage system engineering requires more than design expertise. Most municipal and small community projects begin with the identification of funding and assistance to the municipality in preparing grant and loan applications. Just as important is the proper guidance from the engineer  through the barrage of regulatory compliance issues, timing of loan and grant programs and proper assessment of cost-effective means to solve a communities’ problems.

TD&H staff include certified grant administrators who are extremely familiar with the various funding programs in each region we serve.  Small-to-medium sized municipalities and water districts often rely on a combination of Block Grant funds, loans and grants through USDA Rural Development,  the state Department of Environmental Quality to make a project fiscally viable to a community and its water rates.

Many projects require the issuance of bonds to secure loan funds. This requires a successful bond election by the community. TD&H is proud of its track record in working with communities to develop a public information strategy to keep the community informed and make the passing of a bond issue more likely. TD&H’s media division is able to assist by preparing project brochures, press releases, and meeting exhibits that convey engineering issues in easy-to-understand layman language.

Most design projects start with the preparation of a preliminary engineering report or facility plan. TD&H works with each client and the state Department of Environmental Quality to determine the system deficiencies and a plan of attack to correct the issues. This work typically requires site visits to assess existing infrastructure, mapping, water modeling, cost analysis, preliminary engineering, and the preparation of cost estimates. TD&H also prepares an environmental document for many of these projects as required by the funding agencies involved.

TD&H engineers include experts in all facets of water system engineering, including well siting and well house design, stream intake systems, water treatment plants, storage facilities, fire suppression, and distribution systems.  Expertise in wastewater systems includes collection and treatment system evaluations and studies, lagoons, treatment plants and discharge permits.

Water resources is a broad concept that covers everything from water use planning to water management through conveyance structures.  Canals, streams, siphons, pumps, irrigation, dams and storm drainage systems are all examples of water management features in which TD&H Engineering excels.  A sound understanding of hydraulics, hydrology and water rights and their impacts on your project are important. Our team can help guide you through your project from planning through construction. Our clients include farmers, developers as well as state, local and federal agencies.  In addition, we have a successful record working with irrigation districts and obtaining state and federal grants as well as assembling complete project funding packages.
