It is composed of -6000 Feel of main distribution lines and -3000 Feet of I.arerallines <br />which supply the laps 10 103, ~.. laps. This system was originally desi}!.ned /0 be insla!led in/he <br />sume trellch as lhe Sewage system when the Subdivisiun was buih <br /> <br />For IlI1known reasons the Irrigo/ion Syslem was installed directly above the Sewer System on the <br />Wlme wade. Becawie of [he 65 Foor drup in the rerrain within Willow /leights. the Irrigation ond <br />Sewer were both 1mralled very deep var.vingJ;"om (he shallowest of.J Feel deep to as much a.\' /7 <br />Feel deep. This was necessary/or the Sewer but florlor (he Irrigation. Additionally much u.fthe <br />Irrigation .system lines were ofa very Iighlll-'eight plastic pipe known as 5U Ft, pipe which had t.l <br />pressure capability ol22.5 PSI. 71lis /igJuweif.:ht pipe was inslu/Ied ~'e'y deep and it appears that <br />ilwasn 't proper~'y' h(Jc~fl//ed resulting inj!a(tened or crushed pipe.1 in some area,l. <br /> <br />In addition ((J tht' aforementioned problems, over ,he period of27 or so years of use, hard <br />Calcium or Limestvne deposits inside the pipes hare reduced the in/ernal sizes to 3inche and <br />less in diameter. <br /> <br />Eq:n thouKh (his is lJ Krid type pipe system, lVe infact (lre distributing warer to most of/he fl1P;o, <br />fhru one very /imited path which allows no more dum J 2 fo J.J users at one time. <br /> <br />Because offhe problems and the depth. we have elected to install a new system ahove the old <br />;o,)'stem utilizing mudern heavier pipe, and at a more reamnabJe deplh of22 " to 30" to TOP. <br />Additionally we Will he inslt1l1il/& cleanout pipe.I' to ul/ow the sYJ'lem to he cleaned as needed in <br />the future. <br /> <br />I hope this adequately explains fhe ~)'stem problems <br /> <br />Since,.e~v, <br /> <br />,\larley Dildo.
