Roof drainswith Overflow

The Water District works with its customers to protect the drinking water supply from pollution and contamination caused by cross-connections and backflow.

The fix is a simple one: a backflow prevention device. These devices come in various types and sizes, from smaller ones suitable for home use to larger models for apartments, offices and other large buildings.

The Water District's comprehensive backflow prevention program requires the installation of backflow prevention assemblies on commercial buildings, multifamily properties and irrigation systems.

Commercial roof drains are made in several common sizes to accommodate various amounts of water. These drains are installed during the roofing process and connected to internal and external drain systems that carry rainwater down and away while keeping it contained from entering the building. Sufficient drainage for a commercial roof is a top engineering priority and is included in architectural drawings and other roof calculations.

Nevada state code has, since the 1990s, required builders to install the devices in new commercial properties. The Las Vegas Valley Water District retrofits buildings and water services that existed prior to the regulation's passage with backflow prevention devices.

The Water District determines whether an assembly is required at a specific property. Backflow assemblies are installed according to Water District installation requirements, and the district will inspect installations after they are completed.

In most cases the only practical way to ensure protection is to install a backflow prevention assembly at the point of service. That way, regardless of what happens inside the customer's property or what changes are made to private plumbing, the public water supply is protected.

Commercial roofing accessories like roof drains are vital to the overall roofing system. Many commercial roofs are flat or only slightly graded, and these need extensive drainage options to carry away water and prevent leakage or collapse. Your local Mid-Atlantic Roofing Supply center carries a number of different styles and sizes of commercial roof drains for many different applications. We carry roof drains from top brands, including:

Drainage is a critical component in any commercial building, and it all begins from the primary area that catches rainwater – the roof. Planned drainage is a vital part of any building, but commercial roofs frequently need more than simple guttering and downspouts. Large and complex commercial roofing systems may require multiple commercial roof drains to channel large amounts of water off the roof and away from the building. Mid-Atlantic Roofing Supply sources only the finest top brand commercial roof drains for any project.

Even though plumbing code provisions may be rigidly enforced on new construction, experience has shown that "on-site" modifications and alterations of private plumbing are common.

Possible hazards to the public water supply can be created due to cross-connections in private plumbing. These cross-connection hazards may be found in complex mechanical systems or caused by something as simple as a submerged garden hose.

Commercial roofing drain systems are designed with the area of the building’s roof in mind, in order to ensure adequate drainage from several points. The amount of water that can be carried away is crucial to calculate, to prevent water from standing on the roof or overflowing the sides of the building and penetrating the foundation.

Backflow occurs when water that has already entered a facility flows back into the public water system. A cross-connection is a point in a plumbing system where the drinking water supply is or could be directly connected to non-drinking water.
