Water is an essential part of our daily lives. It is a resource we seldom think about until we don’t have it. When you need support with your water supply, our full-service team can address design from a preliminary concept through the close of construction. We can assist with water main replacement up to system modeling, treatment and storage. You can turn to us for:
City of Indianapolis Department of Public Works South Keystone Avenue stormwater outfall construction observation, Indianapolis
Water planning
inventory and condition assessments: cataloging assets and providing long-term planning for rehabilitation, replacement or relocation
system modeling and usage analysis: hydraulic modeling of a water system for sufficient capacity and pressures, as well as to plan for future system looping, upsizing or to help with fire flow analysis
projected-needs analysis: evaluation of growth trends in a community to identify future source water needs, treatment capacities and distribution system sizing
corrosion studies: evaluation of water chemistry and recommendations for reducing corrosivity
updates for certificate of convenience and necessity
As our climate continues to shift, certain areas of the country are experiencing more frequent droughts. Our team can review your source water and work with your community to develop a water conservation and drought contingency plan that will help prepare you for the worst. We can also assist you with creating an emergency preparedness plan that meets the requirements of your state’s regulatory group.

Water design
If your community needs design, bidding and construction assistance, our team can assist you in most areas of water system design.
We specialize in shallow gravel pack, deep long-shaft and submersible wells.
Hanson’s team has designed and overseen many miles of water mains, ranging from small, residential mains through 36-inch, major transmission mains. Our experience covers simple removal and replacement through new water main looping, trunk lines and parallel mains for added capacity. We work hard to plan interconnections within the system and customize the sequence of operation for the connection of the new mains to minimize impacts on customers.
Hanson’s water specialists can work with your community on small booster pump stations to maintain system pressure to high and low service stations, feeding water treatment plants or maintaining system pressures. We can also assist with improving the operation of multiple pump systems to reduce power consumption and save on your operating costs.
Our skilled design team can assist with the design of various water treatment methods, including clarification, pressure and gravity filtration, chemical feed systems, microfiltration and reverse osmosis. We can also help you evaluate and treat your water for emerging contaminants.
Storage, elevated and ground, includes multiple disciplines within Hanson. We employ our geotechnical discipline to evaluate for foundations; our structural discipline to design the foundations; and our water discipline to determine the size, shape, volume and head range of the required tank. We can also recommend a coating system and, if necessary, cathodic protection for the tank.
PFAS mitigation measures
We can help you navigate the U.S. Environmental Protection Agency’s regulations regarding polyfluoroalkyl substances (PFAS) by assisting public water systems (PWS) with sampling, treatment and compliance solutions and implementing mitigation measures. Mitigation can include:
consolidating with neighboring PWSs whose sources do not have PFAS issues
decommissioning wells or intakes that have PFAS issues
pursuing alternative sources of supply that do not have PFAS issues
implementing enhanced treatment technologies for finished water, including adsorption through activated carbon filtration, ion exchange using a selective resin and reverse osmosis
Hanson can also assist communities with the application process for revolving loan funds, including potential grants and principal forgiveness for the PWSs that qualify.
“Why Hanson? I asked myself that question 19 years ago and have never looked back. I have had the opportunity to design the types of projects that epitomize the term ‘infrastructure.’ From wastewater treatment plants and large pump stations to locks and dams and transmission mains, I can’t imagine working anywhere else.”
