No Flow In
Flow
Manhole Dish / Insert
An Economical Solution to a Costly Problem
One of the most important problems facing the 21st century is
water conservation. The water and sewer industry will be called
upon to find new solutions to old problems to insure that water
is treated and used efficiently.
During rainy weather, an average manhole contributes from 3,000 to 12, 000 gallons per day of rain water, to, the treatment systems.
The NO FLOW IN FLOW dish is made to requirements from virtually indestructible material to offer a simple to install, long lasting product that eliminates sheet flow of rain water into the sanitary sewer system. Added advantages are the elimination of debris and dirt and reduction of manhole odors and manhole cover rattle noise.
BENEFITS
- 5 year warranty on the body of the in flow dish. ( .150 Material Thickness )
- 10 year warranty on the body of the in flow dish. ( .187 Material Thickness )
- Ventilation by valve or vent hole.
- Manufactured of ultra high density, high molecular weight polyethylene. (Marlex HXM 50100)
- Brittleness temperature to a -180° Farenheit.
SPECIFICATIONS
- The dish is made of ultra high density polyethylene copolymer material that meets ASTM specifications designation D1248, Class A, Category 5, Type 111 with a minimum impact brittleness temperature of -180° F. The thickness shall be uniform 1/8" or greater. This material is corrosion proof from all gases associated with waste water collection systems.
- The lift strap is made of a woven polypropylene web and is attached to the bowl of the dish by a wide head stainless steel rivet and a stainless steel 3/4" backup washer. All cut edges are seared to insure against raveling.
