4.2.2 OUTFALL SYSTF-IVS 468.00
2. Solid wall HDPE tightlines must be designed to address the material limitations, particularly thermal
expansion and contraction and pressure design, as specified by the manufacturer. The coefficient of
thermal expansion and contraction for solid wall HDPE is on the order of 0.001 inch per foot per
Fahrenheit degree. Sliding sleeve connections shall be used to address this thermal expansion and
contraction. These sleeve connections consist of a section of the appropriate length of the next larger
size diameter of pipe into which the outfall pipe is fitted. These sleeve connections must be located as
close to the discharge end of the outfall system as is practical.
3. Solid wall HDPE tightlines shall be designed and sized using the applicable design criteria and
methods of analysis specified for pipe systems in Section 4.2.1.
4. Due to the ability of solid wall HDPE tightlines to transmit flows of very high energy, special
consideration for energy dissipation must be made. A schematic representation of a "gabion mattress
energy dissipater" has been provided as Figtire 4.2.2.D . Flows of very high energy will require a
specifically engineered energy dissipater structure, as described above in General Criterion #3.
Caution, the in -stream sample gabion mattress energtl dissipater ma , not be acceptable within the
ordinary high water mark offish -bearing waters or wheregabions will be subject to abrasion front
upstream channel sediments. A four-sided gabion basket located outside the ordinary high water mark
should be considered for these applications.
