DESCRIPTION:
    PARSON MANHOLE INSERTS are manufactured from ultra high density, high molecular weight polyethylene and have been proven effective in reducing or preventing surface water inflow to the collection system, through the manhole lid. Operating, utility and maintenance costs for plant equipment and pumps are minimized, due to reduced flow during heavy rainfall. PARSON MANHOLE INSERTS are a practical solution to expensive plant expansions, new construction moratoriums or high sewage treatment costs.

ADVANTAGES of PARSON MANHOLE INSERTS:

Parson Manhole Inserts offer a full return on investment in less than 10 hours of rainfall!
  • NO VALVE method of ventilation available
  • Single or double valve ventilation system available
  • NO corrosive parts
  • Easy installation and removal
  • Requires no maintenance
  • Dramatically reduce sewage treatment costs
  • Keeps grit, sand, salt, chemical spills,
    foreign objects, road oils, etc. from
    entering the collection systems

    manhole covers with "water-tight" covers
PHYSICAL PROPERTIES:
PARSON MANHOLE INSERTS are manufactured from High Density Polyethylene, meeting the requirements of ASTM D-1248, Class A, Category 5, with a finish thickness of 1/8”. Ventilation is achieved by either the thru-bore, single or double valve methods.
