Ngokufakwa kwezinzwa zokugeleza eChitlapakkam Lake ukuze kunqunywe ukungena nokuphuma kwamanzi echibini, ukuncishiswa kwezikhukhula kuzoba lula.
Minyaka yonke, i-Chennai ibhekana nezikhukhula ezimbi kakhulu, izimoto zikhukhulwa, izindlu zicwiliswe futhi izakhamuzi zihamba emigwaqweni egcwele izikhukhula. Enye yezindawo ezithintekile yiChitlapakkam, etholakala phakathi kwamachibi amathathu - iChitlapakkam, iSeliyur neRajakilpakkam - endaweni yokulima eChengalpettu. Ngenxa yokuba seduze kwayo nalezi zindawo zamanzi, iChitlapakkam ihlushwa yizikhukhula ezinkulu ngesikhathi se-monsoon enamandla e-Chennai.
Sesiqale ngisho nokwakha umlawuli wezikhukhula ukuze ulawule amanzi agelezayo ageleza ezansi nomfula futhi akhukhule ezindlini zethu. Wonke lawa mapayipi axhumene ukuze athwale amanzi ezikhukhula aye eChibini laseSembakkam ezansi nomfula.
Kodwa-ke, ukusetshenziswa ngempumelelo kwala madrayini kudinga ukuqonda umthamo wawo wokuthwala kanye nokuqapha ukugeleza kwamanzi amaningi ngesikhathi sangempela phakathi neziphepho. Yingakho ngiqhamuke nesistimu yezinzwa kanye negumbi lokulawula ichibi ukulandelela izinga lamanzi emachibini.
Izinzwa ezigelezayo zisiza ukunquma inani eliphelele lokungena nokuphuma kwechibi futhi zingathumela ngokuzenzakalelayo lolu lwazi esikhungweni somyalo wokulawulwa kwezinhlekelele ngesipele esingu-24/7 namalungiselelo e-WiFi. Bangakwazi-ke ukuthatha izinqumo ezifanele futhi bathathe izinyathelo zokuqapha ukuze basebenzise abalawuli bezikhukhula phakathi nenkathi yezimvula ezinkulu. Inzwa eyodwa enjalo yechibi okwamanje iyakhiwa eChilapakum Lake.
Yini engenziwa inzwa yokugeleza kwamanzi?
Inzwa izorekhoda izinga lamanzi echibini nsuku zonke, okuzosiza ukulinganisa inani lamanje lamanzi namandla okugcina echibi. Ngokwe-World Development Programme, iChilapakum Lake inomthamo wokugcina we-7 million cubic feet. Kodwa-ke, izinga lamanzi echibini liyashintshashintsha kusukela enkathini yenkathi yonyaka ngisho nansuku zonke, okwenza ukuqapha okuqhubekayo kwezinzwa kungaphezu nje kwesilinganiso sokurekhoda.
Ngakho, yini esingayenza ngalolu lwazi? Uma zonke izintuba neziphumayo zechibi zinezinzwa zokulinganisa ukugeleza, singakwazi ukukala inani lamanzi angena echibini futhi adedele ezansi nomfula. Phakathi neziphepho, lezi zinzwa zingakwazi ukwazisa iziphathimandla lapho ichibi lifinyelela umthamo walo ogcwele noma leqa izinga eliphezulu lamanzi (MWL). Lolu lwazi lungasetshenziswa futhi ukubikezela ukuthi kuzothatha isikhathi esingakanani ukukhipha amanzi engeziwe.
Le ndlela ingasisiza ngisho nokuhlola ukuthi angakanani amanzi emvula agcinwe echibini nokuthi mangakanani akhishelwa emachibini angaphansi komfula. Ngokusekelwe kumthamo nokufunda okusele, singashonisa noma silungise amachibi asemadolobheni ukuze sigcine amanzi emvula engeziwe futhi ngaleyo ndlela sigweme ukukhukhuleka ngomfula. Lokhu kuzosiza ekwenzeni izinqumo ezingcono mayelana nemisele ekhona yokulawula izikhukhula kanye nokuthi kudingeka yini ukuncishiswa okukhulu namapayipi okuvala amanzi.
Izinzwa zegeji yemvula zizohlinzeka ngolwazi ngendawo ebamba amanzi eChitrapakkam Lake. Uma kubikezelwa inani elithile lemvula, izinzwa zingakwazi ukubona ngokushesha ukuthi angakanani amanzi azongena eChitrapakkam Lake, ukuthi kuzokhukhula kangakanani izindawo zokuhlala nokuthi kungakanani okuzohlala echibini. Lolu lwazi lungavumela iminyango elawula izikhukhula ukuthi ivuleke ngendlela efanele njengesinyathelo sokuvikela ukuvimbela izikhukhula nokulawula izinga lazo.
Ukuya emadolobheni kanye nesidingo sokuqoshwa ngokushesha
Eminyakeni yamuva nje, ukungena nokuphuma kwamanzi emvula echibini akuzange kuqashelwe, okubangele ukuntuleka kwamarekhodi okulinganisa isikhathi sangempela. Phambilini, amachibi ayetholakala kakhulu ezindaweni zasemakhaya ezinezindawo ezinkulu ezigcina ukulima. Nokho, ngenxa yokukhula ngokushesha kwamadolobha, kuye kwenziwa umsebenzi omningi emachibini nasezindaweni ezizungezile, okuholela ezikhukhuleni ezinkulu edolobheni.
Ngokuhamba kweminyaka, ukuchithwa kwamanzi emvula kuye kwanda, okulinganiselwa ukuthi kukhuphuke okungenani izikhathi ezintathu. Kubaluleke kakhulu ukurekhoda lezi zinguquko. Ngokuqonda ubukhulu balokhu kuphuma, singakwazi ukusebenzisa amasu afana ne-macro-drainage yokulawula amanani athile amanzi ezikhukhula, ukuwaqondisa kwamanye amachibi noma ukujula imithombo yamanzi ekhona.
