The embankment soils are too steep and were not compacted, which has led to filling in the orifice.Backfill of soils under, adjacent to, and atop culverts is extremely important in realizing their full service life. Pipes should be separated enough so that the soil can be worked into a tight bond with a compactor. Where fill is loosely placed or voids occur in the backfill next to the culvert, a phenomenon called piping can occur. Piping means that water enters the space between the culvert and the backfill, saturates the soil, and slowly washes away fine particles. Over time this action creates larger voids and erodes the soil away until a failure occurs, either when a storm washes out the remaining soil and causes a blowout or when a vehicle sinks into a hole and crushes the culvert. Rule 4. Compact Clean Soil Tightly in and Around Culverts and the Cover MaterialYou can rent a 'wacker' for a few dollars at most rental centers. A wacker is a gas-operated, vibratory, single-operator compactor that can be brought to the site in a pickup truck. You can build a great road and design an incredible culvert crossing, but without compaction of the backfill, you will get to do it all over again. Poor compaction and debris-laced fill are the most commonly diagnosed failures in culvert crossings.Careful placement and compaction of clean fill is needed to install a culvert properly. Installing a granular backfill of pea gravel, often called pipe bedding, in the trench to a depth of 6 in. under the pipe and on both sides up to the midway point aids in draining groundwater and seepage away from the outer walls of the pipe and reliably assists in preventing piping failures.Rule 5. Construct the Road Section Low or Allow for Overtopping to One SideThe sizing of the culvert crossing is for an average year storm. Blockage, larger storms, rapid snowmelt, and debris flows all endanger the roadway and crossing. A prudent designer purposely will depress the road grade to allow for a storm-flow section equal to twice the cross-sectional area developed in Rule 2 to pass over the roadway. The site geometry will determine whether the overtopping section should be directly over the culvert or whether placing it to one side will be adequate. If possible, the overtop section should be placed to one side to prevent the erosive forces of the overtopping mixture of water and debris from destroying the downstream embankment face directly over the culvert. Overtopping to one side often causes the water to flow on a thinner fill section or, even better, over stable native ground. If the overtopping section is strategically placed and sufficiently armored, the access road will still be in place once the floodwaters have passed. Rule 6. Use Maximum Sideslopes of 2:1 (H:V) and a Road Surface Width of at Least 12 Ft. to Calculate the Pipe LengthA common problem with culvert installations is trying to get by with a short pipe length. The design needs to take into account the sideslopes, depth of cover, and roadway width to calculate the necessary length of pipe. Sideslopes steeper than 2:1 generally are not stable and erode quickly in the first few years. Steep slopes are difficult to establish vegetation on and hard to maintain. The slope should meet the bottom of the pipe and not the top; the latter causes a very steep point over the pipe that easily is eroded. Add together the diameter of the pipe twice, the slope length (cover times slope) twice, and the roadway width to determine the pipe width. For pipes set in steeply sloped channels, more length is needed, but in general this approach works for a majority of the crossings. If possible, always install a factory-made flared end section on the pipe, which aids in outfall dispersal of the stormwater and makes road embankment sideslopes above the pipe more stable.

If you're considering installing new plumbing or re-plumbing a house, one of the major decisions is which type of plumbing to use. Lead is of course out due to the health concerns. Copper, iron, bronze and galvanized pipe are still in use. However, plastic pipes come with a number of advantages that should make it the default solution for most situations.
Polyvinyl chloride or PVC pipe can be used for nearly every application, including drain pipes, cold water supply lines and vents. CPVC or chlorinated polyvinyl chloride pipe is better suited for hot water lines due to its greater heat resistance. Let's look at the advantages of plastic pipes over the alternatives in plumbing systems.
1) Corrosion :-
Metal pipes can corrode over time. Iron, of course, will rust. Copper pipes can corrode when exposed to rust from a corroding hot water heater; this can contaminate your drinking water. Any metal pipe will degrade over time due to oxidation. All pipes can wear down due to cavitation or excessive pressure at one point, but it is easier to replace plastic pipe than metal pipe. Simply unscrew the connections and install a new one. Compare that to metal pipe that often has to be cut with a metal saw, new pieces installed, and all of it welded into place.
2) Resilience :-
Another advantage of plastic pipe is how resilient it is. It will resist corrosion almost anywhere, including when it is buried under your yard or embedded in a concrete slab. This explains why the pipes running to your septic system or sewer line are almost always plastic regardless of the type of pipes inside your home.

While the minerals that make water hard can build up inside of any type of pipe, the smooth inner surface and overall resistance to wear mean it takes much longer for water scale to clog your pipes. Your plastic pipes will therefore work far longer before you have to deal with water pressure drops due to mineral buildup.
3) Water Safety :-
PVC pipe (lead free) is always safe to have in contact with your drinking water. It is non-toxic. A little rust in your water isn't going to hurt you, but corrosion from your copper pipes due to the rusting connections upstream can cause problems. CPVC will last even longer than conventional PVC pipes. In every case, PVC pipes won't leave that metallic taste metal pipes can give your water. The fact that PVC pipes are less likely to develop pitting can improve your water safety by not giving bacteria a breeding ground within the pipes themselves.
4) Cost :-
A clear benefit of plastic pipes is their lower overall price. They're cheaper to make than metal pipes. They cost less to transport, as well. The lower price of plastic pipes provides a number of side benefits for homeowners. For example, because they're so cheap, stores are willing to continually stock a variety of sizes. You can almost always find cheap replacement parts for sections of pipe, connectors and angles. A potential benefit of plastic pipes is that a homeowner could replace a cracked pipe or leaking portion on their own instead of calling in a plumber with the necessary tools to fix it.
Summary - The numerous advantages of plastic pipes mean that they should be your first choice when it comes to piping. Do your research and find out which type of PVC or CPVC pipes are best for your particular project.
