During an average rainfall, tens of thousands of gallons of clean water (Inflow) can enter a Sanitary Sewer Collection System through the manhole cover every minute. With treatment costs continuing to rise, that unnecessary expenditure of funds, over time, can become a rather large sum. Installing PARSON MANHOLE INSERTS under manhole covers can dramatically reduce those additional treatment costs. Customize our Inflow Cost Anaylsis to show how your municipality will save up to $734,688 in only 5 years of ownership. PARSON MANHOLE INSERTS are easy to install or remove and maintenance-free.

Parson Water Valve Box Inserts
A common problem with opening, closing or exercising water valves is that they are usually covered with dirt, grit, mud or stones, which makes the valve very difficult or impossible to operate. Time must be spent cleaning out the valve box before any other work can be done. Our PARSON VALVE BOX INSERT saves time and money by trapping the unwanted items that would normally enter the valve box, keeping the valve clean and ready for operation. It is manufactured from the same HDPE material as our Plastic Manhole Insert and includes 1 nylon lifting strap for easy installation or removal. Designed to fit Tyler 5 ¼” boxes, but other sizes may be available upon request.
Parson Odoreater Manhole Inserts
Unpleasant smells are just a part of the sewer business and the people who work in the industry accept it, for the most part. However, the residents in the community have a different idea of what is acceptable, especially when those smells are coming from manholes in their neighborhood. It may disrupt a backyard gathering or a front yard chat. Either way, it’s unacceptable and the municipality will most likely be getting a phone call. Correct the problem quickly, easily and permanently by installing PARSON ODOREATER MANHOLE INSERTS or PARSON ODOREATER CC MANHOLE INSERTS in those problem manholes.
