The following notice was posted this week on the official City of Aurora, Missouri Facebook page by city manager Jon Holmes.

As part of an ongoing effort to maintain its aging sewer system, the City of Aurora is implementing a Voluntary Pilot Private Inflow and Infiltration (I&I) Building Evaluation Program to reduce wet weather flows in the sanitary sewer system.

The goal of the program is to identify and potentially remove cost effective sources of rainwater that should not be getting into the sanitary sewer system. When rainwater gets into the system, it goes through the costly (and unnecessary) sewer treatment process and, in times of heavy rain, can exceed the capacity of the system. Much of the excess water comes from uncapped sewer clean-outs, downspouts, building sump pumps and area drains that are improperly connected to the sanitary sewer system. Keeping rainwater out of the sanitary sewer system can potentially save ratepayers money by reducing the need for costly future capital expenditures.

To assist in this effort, the City of Aurora has contracted with TREKK Design Group to conduct these evaluations. In the coming weeks, citizens may be contacted by staff from TREKK Design Group by mail or by phone to ask if homeowners would like to assist the City of Aurora in this effort. Participation in this program is voluntary, but the City of Aurora encourages you to please consider assisting us in this project.

TREKK Design Group will be requesting to schedule a plumbing evaluation of your property. Again, please remember there is NO CHARGE to the homeowner. For your convenience, TREKK will schedule the evaluation at a time that is convenient for you.

Staff from TREKK Design Group will typically conduct plumbing evaluations as a two-person team. Each staff member will be wearing an identification badge showing a company logo and a name. Their vehicles will have the TREKK Design Group logo on the door panels for easy identification.

Property owners are encouraged to accompany the team throughout the evaluation, but it is not required for all evaluations. Accompanying persons must be an adult (age 18 or over). Plumbing evaluators will be looking for connections to the sewer that allow rainwater to enter the sanitary sewer. Evaluation teams will only need access to your basement or crawl space for the interior portion of the structure.

Examples of connections to be reviewed by evaluators are:


Sump pumps/Sump Pit Foundation drains


Uncapped Clean-outs Downspouts Yard drains

We will be focusing our initial efforts in the north sections of Aurora, north of Crescent street. Please contact TREKK at 890-9465 or email if you would like to participate in the plumbing evaluation at your property.
