<br />This letter rcpart was prepared to evalu"t~ the c()r.dition of SJllilary Litl Statbn Nt!. 1, iocared on
<br />CSAH 14 jll~l w~st ofW.ter \\'arks. The report call be LIscd as a plmUling dOC\11l1ent for the
<br />renovation Oflhis lift slilt;tJn.
<br />
<br />Li fl Statioll No. 1 ~lld Lift Station No. 1 W~I'C rescurched and Ih~11 in'pected in 1999 to ev(i1uate
<br />(;vcrnll cQndition, desig~., ,md reliability. The pLll1lp cupacities \\'cr~ also ch~cked through dlrccl
<br />measmenlcnr of incoming and pumped 110ws. R~com:ncnd~tialls were f(.l11lulaleJ to lay out th~
<br />steps necessary to rcnovate the lift statiolls. In general, it was found that the lift stations have becn
<br />st<tisfaclOrily c.red for from a labor standpoim, but equipment replaccments have not kept pace with
<br />gellctally accepted Llsefllllife estimates. Most of the key mechcmi<;alcoll\pOncllts have net been
<br />replaccd and arc operating at risky mainlenance levels because they are serving beyond their \1sefui
<br />lives. Liti Swtiotl No. 2 wU511pgr~ded ~nd equipment replaced in 2000. The work tlw is reqltired
<br />to upgmdc: Lr i\ Slal ion No. J has not b~~n e011lpktcd to d(lte.
