The Mifflin Co unty Pub lic Sew er Plan (MCPSP) up dates the 1979 Mifflin County Co mp rehe nsiveArea -Wide Wate r and Sew er Plan. The M CPSP a lso c onsolida tes the ma ny municipa l Ac t 537

I. Demographic and Economic Overview

The d em og rap hic and ec onomic p rofile highlights spe c ific co nd itions that ha ve c hang ed sinc ethe c om p letion of both the M ifflin County Com prehensive Plan: Pat hs and Bridges to the 21st

Centuryalong with the e cono mic de velopme nt strat eg y. The p rofile highlights those a rea s that

direc tly relate to the d eve lopm ent o f the MC PSP.

Historical Demographic TrendsA reg ion s infrastructu re investment is d irec tly rela ted to a reg ion s pop ulation. Mifflin Co unty hasseen a slight p op ulat ion increase over the last dec ad e. Exam ining the d ata in g reater detailreveals the reg ions older communities have e xperience d a hollowing out o f its urba n co re,lead ing to a loss of tax and rate base, coup led with diminished ec onom ic develop ment in mostof these area s. The only exception to this trend is Kistler Boroug h w hich ha s w itnessed a mo destincrease of thirty persons. Conc urrent with the hollowing out of the urba n core, landdevelopment activity continues to climb in once rural c ommunities due to imp rovements intransportation, sewer a nd wa ter infrastruc ture. Lew istown Boroug h, the Co unty Sea t, andad jac ent m unicipa lities in the south c entral reg ion of the County still co ntain the highe stpo pulation density how eve r; all of these municipa lities have witnessed a significant p op ulationloss ove r the p ast tw ent y yea rs.

Housing TrendsHousing direc tly influenc es pub lic sew er planning. The p lac em ent o f new ho using a nd thedensity in wh ich it is built dic ta tes the typ e o f sew age d isposa l nee ded . Hence, it is nec essary to

und erstand the existing ho using stoc k in o rder to p rop erly p lan fo r future sew er infrastructu re.The Countys hollow ing out of pop ulation is also noticeab le in the housing loss in many of theBoroughs. The loss of homes can be a ttributed to hom es that we re dem olished or co nversions toothe r uses. The t rend , ident ified in the Co unty Com prehe nsive Plan, of the housing stoc k in theCounty outp ac ing the po pulation g rowth c ontinues to increase. With mo re homes be ing builtfurther away from urba n c ores afforda ble infrastruc ture imp rovem ents will bec ome increasinglydifficult. By tak ing the d ifferenc e b etween the 2000 population and the selected populationprojec tion and d ivide that number by the average pe rsons pe r household, the County will needto provid e roughly 1,556 housing units be tween now a nd 2020.

In orde r to a c hieve these go als, the a mo untof nutrients (mainly nitrogen and phosphorus) entering the Bay tributaries must be reduced.Excess nutrients are seen as the primary pollutants burdening the Bay.

Since 1995, theAuthority has undertaken several storm/sanitary sewer separation projects and has eliminated allbut one of the c om b ined sew er outfalls in the co llec tion system . The m ost rec ent c ollec tionsystem project involved construc tion of new storm sew ers to sep arate c om bined sew ers inBee c h Street a t 7th, 8th, and 9th Avenues, Free dom Avenue a t Oak Street, and S.

Primary clarification is accomplished by a clarigester where primary solids are anaerobicallyd igested in a tank be low the c larifica tion unit. Waste b ioma ss from the t rea tment p roc ess is a lsopum pe d b ac k to the prima ry clarige ster.

The g rit system will only be op erated whe n higher flows a re a nticipa ted due to a pe nding rainstorm. This req uires the staff t o be mo re awa re of fo rec asted we athe r cond itions and turn theeq uipme nt on at the p rop er time. Add itionally, the eq uipment must be kept in a cond ition so it

c an b e turned on with out any ap preciab le delay. When the grit c ollec tion eq uipm ent isop erated , the ma terial should b e visually inspec ted to d ete rmine the grit c onte nt. The g rit that isrem oved from the system should be dried on the sand drying b ed s, and then b ag ged fordispo sal by Waste M ana ge ment. Fec al and other trea tab le m aterial should be rec ycled ba c kinto the flow strea m via a new ly insta lled d rain system and allowed to flow to the influentc om minutor. This ma nage me nt strate gy will red uce fec al mat ter in the grit, but will inc rea sewe ar on the do wnstrea m units.

The p lants mo nthly ma ximum hydraulic c ap ac ityis 0.90 mg d, and t he m onthly maximum organic load ing capa c ity is 800 pound s of BOD5 per

Based on the 2007 Chap ter 94 Rep orts, the p ermitted c apa c ity of 640,000 ga llons pe r da y w ithan estimate d ave rage daily flow of 372,000 ga llons pe r da y implies a reserve c ap ac ity of 268,000ga llons pe r day.
