Packaged Metering Manhole Installation

If you’re looking for one of the most versatile flow measuring tools in existence, then look no further than a packaged metering manhole. A packaged metering manhole provides a great deal of utility and versatility, making them a great choice for busy water management operations.

When you choose a packaged metering manhole for your system, you will be able to select from a variety of type styles, all of which have their own installation requirements. Read about installation conditions for different packaged metering manhole top styles to make sure you install your manhole the right way.

Choosing a Dome Top

The most common style for a packaged metering manhole is a domed top. Typically, these tops will be found on standard packaged metering manholes and those equipped with grinders. Dome tops are usually made from fiberglass, making them durable and long-lasting, and because they can be opened fully, this top style provides easy access to your primary measuring device.

Unlike other top styles, a domed top is installed on the top manhole edge, meaning the seal will not be watertight. Because of these, domed tops are manufactured to be as much as 18-inches larger than the surface grade. This raised installation means that domed top manholes should only be used in applications where there is no vehicle or pedestrian traffic.

Aluminum Hatches

Another type of manhole top that you could choose is one that is made of aluminum. Although this top style is less common, it can be useful in certain situations. For instance, because these hatches are strong and installed directly over the top of the manhole opening, they make a good choice for areas where there is frequent foot traffic.

The key in successfully installing an aluminum hatch manhole is making sure that the area around your manhole is flush with the hatch, creating a level surface. If you are not able to level the surrounding area, your hatch will jut out of the ground, possibly causing people to trip.

Highway Loading Top

Another manhole top style that you may encounter is known as a highway-loading top. This style of packaged metering manhole looks very similar to a traditional concrete manhole, and will usually be found in a roadway.

When installing a highway-loading packaged metering manhole, the reducer of the manhole will be installed up to a foot below the road grade. This is done to accommodate a frame system or cover that is capable of holding the weight of passing automobiles. While installing these manholes too low usually isn’t a problem, installing them too high can be a serious issue, causing the frame system and cover to be raised above the surface grade.
