Frequently asked Questions

How often should I get my cesspool cleaned?

The frequency of cesspool cleaning depends on the size of the tank, the number of people using it, and the amount of waste generated. Generally, it is recommended to have your cesspool cleaned every 1-3 years.

How long does a cesspool cleaning take?

At CMM we do a thorough service. Please allow for at least an hour, sometimes less or more depending on what the service involves.

Is it necessary to be home during the cleaning process?

Yes, we prefer someone be home at time of service for a number of reasons. For one, we need someone home to run water so that we can be sure all water is successfully flowing throughout your system properly.
