To handle in tha neighborhood of 9,000,000 GPP through our precant system it will ba necessary to Install an additional booster pump at tha reservoir, and owing to tha lneraasad amount of water we will run through the settling basin it will be neces­sary to rales the walls of that basin 2 feat. 3n addition to tha above, X sm recommending tha drilling at this time of another deep wall and another shallow wall. We have had signal success in drilling cur walla with tha 8. S. Hall A Go. rotary rig. This rig will not only drill tha walls in a few days as compared with months required by a cable string, but drills holes uniformly vertical and permits of cementing, gravel packing, etc., which cannot be properly done with a cable string. There are two reasons why X recommend the drilling of two addi­tional wells this year: First: Tha probabilities at Lae Vegas art such that it seems almost certain that either a reduction in head upon our underground sources and the consequent falling off in production, or further housing expansion, or both, will make necessary drilling two additional wells in I9I3 , By performing the work at this time we would save the approximately f$,000 cost of moving the rotary drilling rig in and out - if such a rig is avail­able next year. t
