The discharge of t.he first sa.ni.tary sewer system in Salina occurred on the "West bank of the Smoky Hill River on Ash Street. As the Ci'ty built,-up to the east of this poinT it was nec.essary to extend the system east on Ash street and disc:ha.rge the untreated sewage in:,o the Smoky Hill River at the east. end of Ash street. As the City continued to increase in population, the am01mt of se'wage flow exceeded the capacity of the Smoky Hill River to receive raw sewage and provide enough dilution to prevent odor problems. In 1927 a sewage p-wnping station, 20-inch cast iron force main a.nd primary sewage treatIJient plant was constructed. The pumping station was located at the east end of Ash Street near the outlet of the system. The sewage treatment plant was cmlstr'.'tcted approximately 1-1/2 miles northeast of the City and the force main connected to these two units. In 1947, the City started a program to increase the capacity and also provide secondary treatment at the sewage treatment plant. In the prel.iminary report prepared by Wilson & Company, Engineers on the sewage treatment plant, and, now on file with the City, itw"8.S pointed out that approximately 1,500,000 gallons per day of air conditioning water was being discharged into the sanitary sewer system and it was recommended at that time that aIr condItioning water be diverted to the storm sewer system as the design of the sewage treatment plant would not be sized to care for this air condi- tioningwater if the population increased. 2 In this SalTJ6 report it wascallE'd :: ,) th.e GHyt 2 a Uention that the Ash Street VJmping st,atI::>!lwasinade',:r;:ate in pmrlping capa:.;.ity 0 The City r st,arted planning the enlargemet,tof the p'i.ID1ping capacity but the Kansas St,ate Board of HealtJJ \i8;', tu p'Lmlping the entire flm. of sewage trJol':ghthe present "'(}...:Odl f,,')rce main 0 Their objection being ba.sed on the add 1\:iona1 power C' ():irC:s reqJ,'i.r8c1 t.J p'Jsh tJns lr:wreased flew thr o'::gh t,hIs Inao:i'tlo Th.e;f mai.D.ta.:ined 'tbe ;,:';::t. :if' addi'tit.fna.:l f:;)r~~e main. ca,pac::l.t,y' c01.lld be paId for by sa~nngs In p:-;\,ler C(,st,s 0 Tbe{'efcre, increase the 1:::;8 pac: Ity of the present.

In this study. It "rould appear advisable to consider this construction after the sanitary and storm sewer systems are separated in Salina. Until t;.his is done the present sewer can be u.sed as an emergency overflow to conduct storm runoff to t.he river at the east end of Ash Street. However, this pr"ocedure must be of a temporary na bEe and planning for the separation of these two systems of sewers must be started as soon as possible. Originally the sarli ta.ry sewer system in the north part of Salina was con.structed as combined storm and sanitary sewers. The point of discharge being into the Smoky Hill River near t,he east end of Pine Street. Several years ago plannIng and constr~.lction of a storm se"wer system provided mean.s of separatin.g this system into separate systems. The sanitary sewers were extended south on F'ront Street from P'Lne Street to Ash Street and the sanitary sewage diverted to the Ash Street seuer 0 Thi,j sewHge flow can be diverted to the proposed sewa.ge pumping station. 5 ~ ~~ist..ing East _Ash_~~!:...Pl.'!D.J2irlg St~io~ " The existir..g East Ash Street, pumping station was constructed in 1927. The sta tior! is (;cmstrnct;ed of reinforced c:oncrete S"i.::bstructure and brick pump house. The vleLw'ell and bar sC!reen :i s in the west portion of the substruct'ure. The se~W'age p'l:impS are in the east portien with the electric motors in the pump hOl:.se. The i.'wo portions of the substructure are separated by a solid concrete walL Pump st1ctiofl pipes extend through this division walL The pump house is over the east. portion only. A control manhole is located just south of the pumping station w..'1ich permits flow to the wet well or directly to the river. At the present time maximu..rn summer sewage flows in excess of the pumping capacity is bypassed directly to the river. It will be noted that the only bypassing now occurring is during the summer months, this condition demonstrates the serious condition of air conditioning . water being discharged into the sani t.ary sewer system. During the \ormter months except during rainfall periods the existing pumping station ..rill pump all of the sewage flow, incl':lding peak flows. The item of air conditioning water will be discussed later in this reporto As the City cor:.tinues to i.tlCrease in population this ptlIuping station 14i11 become too small to pump the winter seW'-:i.ge flows and some relief' tV'lll be nece ssary" The pu~pofje of this stTLdy is to nTovide this relief 0 As pein ted out previously the area.s which were outlined to continu.e to flul.! to this station 'will be small encugh to allow the present station to handle the flows with enough reserve capacity to permit addit.ional grGw"th in population in these areas. The map at the end (.I t,hi:s repo:"t 8h()\~'S the areas as disc1..)ssed v The areas outlined are not 'i " sncrtN.tl lTL r,fw deTail bU.t of a general nature. , o - . a detail area is not required since f(;:ture develc.pment is uncertain as to location and extent~ also the capacities of the stations will provide for additional flows in the future and not based on'precise areas now contributing sewage fIol.iS" E~i~~~~-!2!:~~1~i~ " The existing cast iron force main cCfi'Clec::::t:ing the East Ash Street pumping, station to the present sewage treatment plallt, is 20 inches in diamet.er. This force maln runs along the 'w'est bank of the Smoky Hill River from the pumping station to the east side of Ohio Street~ then the force main crosses under the river and continues north alc,ng:;he f,mst side of Ohio street to the north side of the Missouri Par.dfJc; Railroadtrack9 then east along the Missouri Pacific Railroad right...()f-.),oay to the sewage treatment plant" This ;;W-inch force main rms ample capaci t.y fo!' the present pmnping capa.city. Several years ago the C.ity planned to increase the pumping capacity of the existing prllnping station btrt due to the increased friction. that t.folud be created in this force main which wcnll,d ca'::;.se high pumping costs in trying to push this higher flow thrcragh the majn~ ca'u.sed the Kansas State Board of Health to recommend additional force main capacity by building a new force main to carry this increased flowo Faced. vdth the additional costs of a new' force ma:in} ca-JIsed consideratJon of selee ting a site to divide 'the present system and pump 'the excess flc.'<Il's tl"..rough this new force main 0 ? .- M d Q . ~- easure ...,ew-age.n.L~J..ows Sewage flows were measlrred on Ash Street at a manhole located between Second and Third Streets, and at a manhole located at North and Front Streetso Flows were measured for a 24-hour period and measured during hot weather, these flows represent domest.ic sewage flows., industrial waste flows and air conditioning watero The area draining to the Ash Street sewer at the point of measuring serves an est.imated populai~ion of 15,000 persons, the industrial waste is estimated at 1,000~000 gallons per day, the ground water infiltration is estimated at 500,000 gallons per day and the air conditioning water a.t 2,500~000 gallons per day 0 The measured flow for the 24-.hour period totaled 5,414,700 gallonso With a domestic sewage flow estimated at 100 gallons per day per capita, the total sewage floW' estimated and the measured flo'w checks very close 0 . The industrial waste is based on the survey made in Salina at the time the study was made on the sewage treatment plant, since no major changes have been made in the industrial field in Salina since that time it appears reasonable to assume the industrial flows have not changedo The estimated air conditioning water will be discussed latero At the time the sewage nows were measured light ral,n occurred but the amount ...ras not serious enough to reflect on the flowso The area draining to the sewer manhole at Second and Front streets serves an estimated population of 3,000 persons} the industrial waste is estimated at 200,000 gallons per day" the grol1nd'irater infiltration is estimated at 100,000 gallons per day and the air conditioning water at 300,000 gallons per dayo The measured flow for UTe 24-hmlr' period totaled 944,700 gallons, which checks the esti.mated flows. 8 --- Domestic~~ew~e~loW's . In the 1948 report covering the sewage treatment plant for Salina, sewage flows were meas\ITed" At that time the fIo'w of domestic sewage was assumed as 100 gallons per capita per day" At that time this flow was based on recommendations by Imhoff-Fair, Seeley, Clay Products Association, and Davis, all authorities in the sanitary engineering field. To date this information is unchanged and when used, the meas"QI'ed flows were V'ery close to those assumed" Therefore, the domestic: sewage flow of 100 gallons per day per capita will be used in this study" Industrial 'Wastes . In 1948 an exteI1sive s-r;;rvey revealed the i.ndustrial waste flow to be estimated at 1,000,000 gallons per day" Since that time industrial develop.~ ment contributing flows to the sanitary sewers has not increased. However, with the increase in population the existing industries no doubt have expanded operations and the present industrial flows have been assumed at approximately 1,200,000 gallons per day" 9 I r St.orm Sewers Salin.a b.'lS a porticfl of its 58!"itary sewer system which is classified as a combi'v.:.ed. systemo 'This type permits the flow of both sanitary sewage and s tormwater nmoff 0 Most of the sys Lem 'lL."1der t.his classification is located in the b:;;siness sectionc The difficulties of coml::dned.

U + ,H \.Jon ~lo9~ng ~ Salina is faced viith a very serio::ts problem in the Slunrner months caused by the discharge of nonconserved air conditioning watero This is the water t.hat passes thro'Clgh air conditioning equipment only once and then wasted to the sanitary sewer system. Conserved air conditIoning water is that water used in cocling to\tlers or evaporative condensers which provides means of cooling recirculated water 0 A t~pic:a.l example will clarify the above methods of cooling. The qrw.ntity of water that norrnally passes the condenser amounts to approximately :2 ga.llons per minute per ton for the nonconserved equipment as against. nearly 3 gallons per mJ...Ilute fer the conserved equipment 0 Where the conserved equipment is ~.:lsed:1 ho'wever.9 the water is re'L18ed~ with a make-up of approximately 2 percent. of the 3 gallons per minutey cr about . 0.06 gallon per minute per ton of capacity for the a.ir conditioning uniL The above information is based on 1-later usage and ad 12ally with the conserved equipment the discharge to the sanitary sewer system will not be as great as the 0.06 gallon per minut.e per t:m because most of the loss is caused by evaporationo Therefore~ this repcrt will only consider the nonconserved water which is being dis,c;harged to the sanitary se'werso In 1955, the City passed Ordinance Noo 6024 relating t.o the conservation of water &.nd controlling the ~J,se of tf28 :rnmicipal Se\.[6r system; regulating thense thereof' by air conditioning eq':lJ.pment.; prohibiting waste; requIring a permit from the buIlding 1.ns1'';:'0 tor' instan:Lng~ remodeling or adding to any air cond::! tioning system C1:( specls'Led s:Lze l1singwater from the murd:Jipal supply or emptyi.:ng inte lTl1.;.rJ.ic: IDals torn: or ~~anitary se'Ners and providing f'..)r the re'foking thereof9 def cerLa In, terms and providing penalties for t.he. vlo1ati.on o.f its 1.1 .
