Breaks or failures would require undervacer repair. Unitized repair kics 

 would be ready for chis concingency. Divers trained in the techniques would 

 carry out the work. 



Since there is a long period of non-use it should be possible to thoroughly 

 rinse the line and even inject chlorine or other algae cleaning agents that 

 would be acceptable for river release once the line was cleaned. 



Costs and Construction 



Costs of feasibility study, design and construction are not known for this 

 system but considering the alternatives this system should be competitive 

 since the right-of-way cost is low or nonexistent, the plan would utilize 

 existing facilities to the maximum, and power and water needs are modest. An 

 early priority for engineering review of this plan should scope the 

 construccion costs. 



It is envisioned that through modular design of pumps and line sections much 

 of this construction would be done on shore and then barged and located on the 

 allnemenc. Field coupling of pipeline sections would be simple and achievable 

 underwater. 



Power losses for water lost to generation would be nil. Pipelines use would 

 be about 2,000 acre feet for a 24" plastic pipeline with velocity at 2.5 

 ft/sec, operating for a 120 days. Power consumption for this pipeline will be 

 greatly dependent on pump efficiency, but with hydraulic loss per mile at 4.0 

 horsepower and a pump efficiency of lOZ, the electric input would need to be
