Decentralized Wastewater Treatment: A Sensible Solution

Kusamalira madzi onyansa m'madera osiyanasiyana kumaphatikizapo njira zosiyanasiyana zopezera, kusamalira, ndi kutaya / kugwiritsira ntchito madzi oipa m'nyumba zawo, mafakitale kapena mabungwe, magulu a nyumba kapena malonda, ndi madera onse.Kuwunika kwa malo okhudzana ndi malo kumachitidwa kuti adziwe mtundu woyenera wa chithandizo chamankhwala pamalo aliwonse.Machitidwewa ndi gawo lachitukuko chokhazikika ndipo amatha kuyang'aniridwa ngati malo odziimira okha kapena kuphatikizidwa ndi machitidwe apakati ochotsa zimbudzi.Amapereka njira zingapo zochizira, kuyambira kuchiza chosavuta, chopanda kanthu ndi kubalalika kwa dothi, komwe kumadziwika kuti septic kapena onsite system, kupita kunjira zovuta komanso zamakina, monga mayunitsi apamwamba omwe amasonkhanitsa ndikuchotsa zinyalala kuchokera kunyumba zingapo ndikuzitaya kumadzi apansi. kapena nthaka.Amayikidwa pamalo kapena pafupi ndi pomwe madzi oyipa amapangidwira.Njira zomwe zimatuluka pamwamba (madzi kapena nthaka) zimafuna chilolezo cha National Pollutant Discharge Elimination System (NPDES).

Machitidwe awa akhoza:

• Kugwira ntchito m'magulu osiyanasiyana kuphatikizapo nyumba zogona, mabizinesi, kapena madera ang'onoang'ono;

• Kusunga madzi otayidwa kuti ateteze thanzi la anthu ndi madzi abwino;

• Kutsatira malamulo a ma municipalities ndi maboma;ndi

• Kugwira ntchito bwino kumidzi, kumidzi ndi kumidzi.

N'CHIFUKWA CHIYANI AMACHITA MANKHWALA A MADZI OTSATIRA?

Kuthira madzi otayira m'madera okhudzidwa kungakhale njira ina yabwino kwa anthu omwe amaganizira za machitidwe atsopano kapena kusintha, kusintha, kapena kukulitsa njira zomwe zilipo kale zoyeretsera madzi oipa.Kwa madera ambiri, chithandizo chamankhwala chikhoza kukhala:

• Zotsika mtengo komanso zotsika mtengo

• Kupewa ndalama zazikulu

• Kuchepetsa ndalama zoyendetsera ntchito ndi kukonza

• Kukwezeleza mabizinesi ndi mwayi wa ntchito

• Wobiriwira komanso wokhazikika

• Kupindula ndi ubwino wa madzi ndi kupezeka kwake

• Kugwiritsa ntchito mphamvu ndi nthaka mwanzeru

• Kuyankha kukula ndikusunga malo obiriwira

• Ndiotetezeka poteteza chilengedwe, thanzi la anthu, komanso madzi abwino

• Kuteteza umoyo wa anthu ammudzi

• Kuchepetsa zoipitsa wamba, zopatsa thanzi, ndi zowononga zomwe zikubwera

• Kuchepetsa kuipitsidwa ndi kuopsa kwa thanzi komwe kumakhudzana ndi madzi oipa

ZOYENERA KUCHITA

Kuchotsa madzi otayira m'madera ambiri kungakhale yankho lanzeru kwa madera amtundu uliwonse ndi chiwerengero cha anthu.Mofanana ndi machitidwe ena aliwonse, machitidwe ogawidwa m'madera ayenera kukonzedwa bwino, kusamalidwa, ndi kuyendetsedwa kuti apereke ubwino wokwanira.Kumene atsimikiza kukhala oyenerera, machitidwe ogawanika amathandiza madera kufika pa mfundo zitatu zokhazikika: zabwino kwa chilengedwe, zabwino pachuma, ndi zabwino kwa anthu.

KUMENE IKUGWIRA NTCHITO

Loudoun County, VA

Loudoun Water, ku Loudoun County, Virginia (a Washington, DC, suburb), atengera njira yophatikizira yoyendetsera madzi oyipa yomwe imaphatikizapo kugulidwa kuchokera ku chomera chapakati, malo obwezeretsa madzi a satana, ndi machitidwe angapo ang'onoang'ono ammudzi.Njirayi yalola kuti derali likhalebe ndi chikhalidwe chakumidzi ndikupanga dongosolo lomwe kukula kulipire kukula.Madivelopa amamanga ndi kumanga malo osungira madzi onyansa amagulumagulu motsatira miyezo ya Loudoun Water pamtengo wawo ndi kusamutsa umwini wa makinawa ku Loudoun Water kuti apitirize kukonza.Pulogalamuyi imadzithandizira pazachuma pogwiritsa ntchito mitengo yomwe imalipira zolipirira.Kuti mudziwe zambiri:http://www.loudounwater.org/

Rutherford County, TN

Consolidated Utility District (CUD) ya Rutherford County, Tennessee, imapereka zimbudzi kwa makasitomala ake ambiri akunja kudzera munjira yatsopano.Dongosolo lomwe limagwiritsidwa ntchito nthawi zambiri limatchedwa septic tank effluent pumping (STEP) system yomwe imakhala ndi pafupifupi 50 magawidwe amadzi otayira, onse amakhala ndi STEP system, fyuluta yamchenga yobwerezabwereza, ndi njira yayikulu yothirira madzi.Makina onsewa ndi ake ndipo amayendetsedwa ndi Rutherford County CUD.Dongosololi limalola kukulitsa kachulukidwe kachulukidwe (magawo) m'malo achigawo komwe zimbudzi za mzindawo sizipezeka kapena mitundu ya dothi sikuyenda bwino ku tanki wamba wamba ndi mizere yokhetsa.Tanki ya septic ya galoni 1,500 ili ndi mpope ndi gulu lowongolera lomwe lili panyumba iliyonse kuti lizitulutsa madzi onyansa kupita kumalo osonkhanitsira madzi apakati.Kuti mudziwe zambiri: http://www.cudrc.com/Departments/Waste-Water.aspx
