All Clear Septic and Wastewater Services All Clear Septic and Wastewater Services has experience working with customers with cesspools on their properties.  A cesspool is a pit which acts as both a settling chamber for solids and a leaching system for liquids.  The use of cesspools may overload the capacity of the soil to remove bacteria, viruses, and phosphorus, and to nitrify ammonia and organic nitrogen compounds.  Septic Inspections do not require cesspools to be replaced, however, they do need to be maintained, or if they exhibit signs of hydraulic failure, are located extremely close to private or public water supplies, or otherwise fail to protect or pose a threat to public health, safety or the environment they will need to be upgraded.  We provide cesspool services and repairs and have also done cesspool replacements when required.  Today we have appointments for both cesspool repairs and services in Holliston, Millis, Canton, Wayland, Southborough, Boxborough, and Stow, MA.  If you have a cesspool and need cesspool service, cesspool repairs or have any questions please do contact our office at 508-763-4431 or visit
