Octaber 14 � 1969 Mr. G�org� D. Eaetman� Jr. Chief Administrativa Aseistant Offica of the Maqor City Aall Piping Failure Sewage Pwnping Station Page 3 msintenance would not have detected Chie unlees the fitting ehos+ed leakr.ge; we heve no evidence that this ex�.eted . Our lmaoledgs ie that the meint�nance provi.ded in these atatione indicat�s it to be well abm e normal. The City has a competent mnn who has b�en performing in sn excepCionally well mannar and we would reco�end Lt�at with the increasing n�ber of etationa being put on the Ever.att eyatem that this men be given aome early and competent asaietance. The City shauld be aware Chat the floading problem at thia station was compoimdad in that it receivea all of the diacharge from Che pamp aCation No, 2 locatad further aouth. We did not provida an emergency overElow in the deaign ae t1ieC tyQe of an additive item Wae etrongly frowned on Uy the regulatory authorities . It ia possibla thet the CiCy could , withouC advice to the regulatory authoritias , edd en emergency outlmt d3scharging to the sound which could prevant an area floodfng if a similar feilurn occurred in the future. There ia no way, however , to provide an emergency overflow to thia atation that totally protected the interior of Che atation other than eome very expmsive amergency pinuping equipmtnt which again is something mechanical that ie in iteelf could fci1. It is our opinion thaC with the conCinued addition of pumping etatione in the �erett syatem that when moniea become available a compl�ta t�lemetering and warning system be installed � this inetall�tion could include an automatic• controi which would ahut-doan p�p Station No. 2 up�n th�� failure in pump SCation No, 3 . with No, 2 shutdo�m that sewage would continue through the normal bL-pase at that point without cauaing flooding damagea either at Station No. 2 oz Station No. 3 . An autometic warning and telemetering aystem could be mede to report at any aelected poiat in the City ehope any failure or overloading that was occurring in this s}*stem.
