Water & Wastewater

Efficiency at work. Your wastewater system has a significant impact on your budget. CGA engineers use the latest design techniques to minimize clean water infiltration and reduce treatment costs.

Our engineers have a combined 40 years of experience designing and updating wastewater systems. From mapping systems to finding grants, we’re equipped to help with every stage of your project.

System Updates

Smoke tests and flow rate tests help determine what improvements your wastewater system needs. We’ll create a detailed map of your current system and demonstrate the financial benefits of completing infrastructure updates.

By completing a detailed analysis, we’ll create a plan to prolong the lifespan of your current system and save you money.

New Construction System Designs

Our staff will analyze factors that might affect your wastewater system design, including the topography and elevation of the land.

We’ll design the most efficient and cost-effective plan so your system runs smoothly for many years to come.

Funding Assistance & Cost Estimates

Funding and grant writing are some of the most complex parts of updating or designing wastewater systems.

Our staff will create an estimate of expenses and help you find funding so that you can get started on making important updates.

New Construction Permits

We’ll keep your project on schedule by assisting with necessary permits for your project.

CGA has worked in over 241 cities in Iowa, each with unique regulations. Our detail-orientated staff carefully follows the regulations in each city.

Per the NPDES permit, Ammonia Nitrogen and E. coli limits must be met by July 1, 2021.

Did you received a Compliance Schedule from the IDNR?

The new permit requires a higher treatment level for Ammonia Nitrogen, Total Nitrogen, and E. coli along with Stream Diffuser special monitoring and a Bathymetric Analysis.
