Water & Wastewater Engineering
The Willett, Hofmann & Associates, Inc. Water & Wastewater Engineering Department provides professional engineering services for the design of potable water systems and wastewater collection and treatment systems for projects of various sizes and complexities. The WHA staff is experienced in guiding the client through all three (3) phases of a project: Planning/Funding, Design and Construction.
In the Planning/Funding Phase, the WHA staff will evaluate the client’s problem, develop a cost-effective solution and recommend funding options for the project. The WHA staff works regularly with the IEPA Public Water Supply and Water Pollution Control Revolving Fund Loan programs, USDA Rural Development Water & Waste Disposal program and Department of Commerce & the Economic Opportunity Community Development Block Grant program to obtain grants and low interest rate loan financing for our clients.
In the Design Phase, our engineers work closely with the client to develop a design solution that meets all their project goals. The design solution will strive to address the cost effectiveness and ease of operation and maintenance for each project.
In the Construction Phase, our engineers will assist the client in the bidding and award of the project and provide project construction administration. Our field technicians are experienced in observing the construction activities and working with the contractors to achieve a quality construction project that is completed on time for the client.
