Why Your Phone Isn’t Ringing
and How to Fix It Fast
If your phone isn’t ringing like it used to, there’s a reason, and it is usually not what you think. In this session, we will break down the most common causes of low call volume for septic and wastewater businesses and show you how to identify what is holding you back.
You will learn how customers are actually finding your business online and what influences their decision to call. We will also walk through a simple, practical checklist you can use to start generating more calls within days, not months.

Homeowner Workshop on Septic Systems
2026-07-23 17:30 - 19:00 (America/Chicago) | Watershed Committee of the Ozarks, 2400 E Valley Water Mill Road, Springfield, MO, 65803, United States
The Watershed Committee of the Ozarks in partnership with Missouri Smallflows Organization, Greene County and the Missouri Department of Natural Resources invite local landowners to an educational walking tour on Thursday July 23 at 5:30pm to learn about septic system maintenance, how to extend the life of a septic system and provide information on current pumpout rebate programs available. Failing or poorly maintained septic systems can pollute both groundwater and the surface streams, rivers, and lakes where we swim, fish, and paddle.
The FREE educational walking tour will begin with a presentation inside at the Watershed Center 2400 E. Valley Water Mill Road Springfield, MO 65803 on Thursday July 23 at 5:30pm. Then will be followed with an outside walking tour at the Onsite Wastewater Training Center at 4007 Farm Road 171 Springfield, MO. The event is free to attend but RSVP to 417-408-3310 is encouraged. Light refreshments will be provided.
This project is funded in part by the United States Environmental Protection Agency through the Missouri Department of Natural Resources under Section 319 of the Clean Water Act. For more information, contact Stacey, Projects Manager for the Watershed Committee of the Ozarks at 417-408-3310 or watershedcommittee.org

Webinar: The $0 Marketing Budget: What To Do Before You Spend a Dime on Ads
2026-08-12 18:00 - 19:00 (America/Chicago) | MO
Ads don’t fix a broken system. They just send more traffic to it faster. Before you spend a dime on advertising, make sure your website converts, your Google Business Profile is fully optimized, your leads get fast follow-up, and your branding is consistent across your ads, website, and trucks. We’ll also cover reviews and basic tracking, so you know what’s working once ads are on. Get these right, and every dollar you spend on ads turns into calls and jobs instead of wasted clicks.
Thank you to Dig In Digital for sponsoring this webinar! No CEUs are awarded for this seminar.
