We partner with cities, counties, Metropolitan Planning Organizations (MPOs), and other local government organizations to improve infrastructure in communities through a wide variety of project types. We work closely with government officials and staff, community stakeholders, and contractors with the goal of creating local infrastructure that is safe, efficient, and sustainable.

Sanitary sewer infrastructure represents a tremendous investment for cities. Each day, communities of all sizes depend on miles of underground sewer lines to transport millions of gallons of wastewater. Because these systems are unseen, defects and deterioration often go unnoticed until a problem arises above ground. When ignored, aging sanitary sewer systems experience complications that can lead to public health hazards, cause unplanned service interruptions, and require expensive emergency repairs. One of the most common defects of a deteriorating sanitary sewer system is large amounts of infiltration and inflow (I/I). This increased groundwater and stormwater load on the network can create manhole surcharges during rain events and disrupt the wastewater treatment process.

Sanitary sewer rehabilitation extends the life of aging collection and conveyance systems using various construction techniques. Whether it is manhole rehabilitation, pipe rehabilitation, or both, these projects allow cities to preserve one of their most vital assets.
Here are four tips for successful sanitary sewer rehabilitation:

Children love to explore. Whether that's at a park specifically designed for them or while they are tagging along to an outdoor space with parents, kids find features of play anywhere. Plantings within areas frequented by children can add an element of play, or they can create hazards cities would rather avoid. When designing outdoor spaces, one should always consider which guests are expected to visit there. When the target audience or even the occasional visitor includes children, landscape architects must factor this into their design criteria, specifically the plant material.

There is an unseen, but avoidable, cost in construction and development. Underground utilities hide below the surface of right-of-ways, run under roadways, and thread their way between buildings in highly developed areas.
Most municipal infrastructure projects start with utilities. Utilities create the roadmap for services that keep a city ticking. Gas lines, water mains, and gravity-fed sanitary sewer are interspersed with electrical lines, and, closer to the surface, cable or fiber internet. All of these utility lines can create a complicated matrix of underground obstacles to deal with.
