Our porta-potty crew has been on the move today, traveling all around Monroe County delivering portable restrooms for surprise birthday parties, Halloween parties, fall festivals, fundraisers, and other special events!

While we love staying busy and helping our customers with their events, some of our favorite deliveries are the ones where we get to give back to the communities that continue to support us!

Today, we were honored to donate portable restrooms to the LaSalle Township Fire Department for their Fall Festival!

We were also proud to donate portable restrooms for the Conor Harrigan Memorial Golf Outing at Dundee Golf Course to support the Harrigan family!

Being a locally owned and operated business means so much more to us than just providing a service. It’s about building relationships, supporting our neighbors, and giving back whenever we have the opportunity.

We are extremely thankful for the continued support from our customers, local organizations, fire departments, and everyone who allows us to be a small part of their events. Without our community, we wouldn’t be where we are today!

As the fall season continues, our crew is staying busy making sure events all across the county have clean, dependable portable restrooms!

📞 Planning an event? Give us a call! Whether it’s a backyard birthday party, wedding, festival, fundraiser, or large community event, we’ve got you covered!

NEW SEPTIC RISERS GOING IN TODAY!

Our customer originally called us out for a routine septic tank pumping, but while we were there, he decided he was tired of having to dig up his septic tank every time it needed maintenance!

We were happy to help! We picked up a set of new septic risers and got them installed today, making sure everything was properly fitted, sealed, and secured with concrete around the risers to help prevent shifting or movement over time.

✅ No more digging up the tank for routine pumping!
✅ Easy access for future septic maintenance!
✅ Properly sealed and secured for long-term use!
✅ One less thing for our customer to worry about!

We always tell our customers that septic maintenance doesn’t have to be a hassle! Adding risers is a great investment that saves time, labor, and headaches down the road.

Whether you’re due for a routine pumping, looking to install septic risers, or need other septic services, our crew is ready to help!

Tonight, some of our crew traded in the work boots for a night of football under the lights! 🏈

We had a great time getting out and catching up with some familiar faces, friends, and customers throughout the Ida community!

A special shoutout to Brett #77! Brett spent his summer working alongside our porta-potty crew, helping with maintenance, deliveries, and plenty of odds and ends around the shop. We sure appreciated all his hard work this summer, and it was awesome getting out tonight to watch him on the football field!

Our crew had a full schedule today, bouncing from one end of the county to the other! Between routine septic pumping, septic inspections, porta-potty servicing and deliveries, and other septic maintenance and repairs, the guys have been staying busy!

With winter right around the corner, now is a GREAT time to think about your septic system!

When was the last time you had your septic tank pumped? If you can’t remember, or it’s been a few years, it might be time to get it on the schedule!

We always recommend getting your routine septic maintenance taken care of before the freezing temperatures, heavy frost, and snow arrive. A little preventative maintenance now can save you a lot of headaches down the road!

At Denniss Septic Tank Service, we’re proud to be your local one-stop shop for septic pumping, inspections, repairs, porta-potty rentals, and all your septic maintenance needs!

As we wrap up another busy day, we want to give a big thank-you to our hardworking crew and all of our wonderful customers who continue to trust us with their homes and properties.

📅 We’re still scheduling septic maintenance before winter hits!

Another Successful Trunk-or-Treat in the Books!

The crew had an awesome time participating in another Trunk-or-Treat at Ida Elementary School! 🎃

We absolutely love being a part of events like this and getting the opportunity to give back to the community that continues to support our small business year after year!

It was great seeing so many wonderful families, familiar faces, and customers stopping by to say hello! We loved seeing all the creative costumes, smiling faces, and kids having a blast collecting candy! 🍭🍫

A huge thank-you to Ida Elementary School and everyone involved in organizing this awesome event! We appreciate all the hard work that goes into putting something like this together for the kids and families in our community.

Thank you to everyone who stopped by! We had a blast and can’t wait to do it again next year! 🎃

The Denniss Septic Tank Service crew took a little lunch break today and stopped in at Gino’s Pizza & Sub Station in Ida for some delicious breakfast pizza!
Gino’s in Ida

Normally, you can catch our guys stopping by the Bluestreak Snack Shop around lunchtime for one of Chris’s famous burgers or some ice cream, but today we decided to switch things up and give Gino’s a visit!

A big shoutout to both Gino’s Pizza & Sub Station and Bluestreak Snack Shop for keeping our guys fed and fueled throughout the workweek!
