Flotation (Buoyancy) Comparison
Resource #  07-125

Buoyancy forces that affect a buried pipeline should always be a design consideration, especially in site conditions with a high probability of flotation.  This brochure explains the average density of concrete pipe as compared to corrugated PE pipe. The proof is in the pictures of this brochure that show jetting or collapse of high density polyethylene culverts and the roadways because of flotation.

Least Cost Analysis
Resource #  07-130

Pipelines, culverts, and related drainage facilities are vital components of our infrastructure. Durability and economics should be given proper consideration for transportation or drainage projects, since lower initial costs do not always result in the most economic product. This brochure will guide the decision maker in using least cost analysis to identify the product with the lowest total cost, based on the present value of all initial and future costs.

Underground Storm Water Storage Systems - The Cost Effective, Efficient Way
Resource #  07-129

Keep mainline pipe sizes smaller and/or utilize existing drainage when developing new areas by installing an Underground Storm Water Storage System.  In areas prone to heavy rain or flash flooding, this system allows for the collection and storage of the water which can later be discharged into the system at a controlled rate. In dry areas, water can be stored for use during droughts or other times of need.

The Infrastructure is Collapsing
Resource # 07-128

Our infrastructure is deteriorating at an alarming rate. The recent rash of drainage system failures is cause for concern for many reasons, the least of which is major interruption to our public and private thoroughfares. Failure also raises issues of public safety and liability. The public is being hit with costs to repair these deteriorating infrastructures in the manner of taxes and fees. This brochure identifies some recent failures and the known costs of some.

Hydraulic Efficiency
Resource #07-127

The hydraulic design of a drainage system involves an economic evaluation. Design engineers and owners can select the proper size drainage pipe for a specific culvert or sewer application by applying Manning's n values as design values and not laboratory values.
