Kunakekelwa kwe Manti
The Gariep Dam forms the largest storage reservoir in South Africa, it supplies water to part of the Vaal, Fish and Sundays catchments as well as irrigation along the Orange River.
Emaphesenthi emashumi lasikhombisa, endzaweni lengetulu yemhlaba, ivalwe ngemanti. Emaphesenthi lamashumi layimfica-nesikhombisa emanti onkhe emhlabeni ngemanti eluswayi. Lokungaphansi kwemaphesenthi lamatsatfu kwemanti onkhe ngemanti lamasha.
Kulo 3% wemanti lamasha, ngetulu kuna 0.3% ngemanti langetulu lekumelula kuwatfola kutsi singawanatsa noma siwasebentise etintfweni letikudla netintfo lesitikhokha kutsi tihlale tiphila. Lolokusele ngu:
69% - Lokuciniswe nge ayisi
0.74% - Tigadla tagesi letigegelete lomhlaba
30% - Ngaphansi
Emanti yindlela lekalekile. Linani lemanti lebekakhona emhlabeni eminyakeni letigidzi letengca likhona naylo futsi angeke likhuule. Intfo letogucuka yindlela lesiyisebentisa ngayo nalendlela yekutsi sihlale siphila. Kufuna sifundze kutsi singamosi. Lamantin lamasha lesiwasebentisako:
70% usetjentiswa ekulimeni
20% wetintfo tekusebenta kanye na
10% wasemakhaya kanye netintfo letinye lesitisebentisako.
Kute sikhokhe kudla kumele sente indlela yekwakha kute sitfole tindlela letinsha kutsi sisebentise kancane mphindze simoshe kancane ekukhiciteni kudla kwetfu.
Kukhokha likilogram linye lenyama lebovu kutsatsa 15 000 wema litha noma 15 m³ wemanti.
Kukhokha likilogram linye lelilayisi kutsatsa 3 500 wemalitha noma 3.5 m³ wemanti.
Sinenhlanhla kutsi ngetekulima, sento sekwakha intfo lensha sekusiletsele tindlela tekutsi sinake kutfwaleka kwemanti emhlabatsini. Loku kuvumela kunisela kusebente kahle ngendlela lensha phindze lephansi ngekumosha ngekunisela kufana nendlela yekunisela ngetulu nangaphansi ngemaphayiphi. Kepha solo kuyafana, ngetulu kwa 60% wemanti lasetjentiselwa kunisela ekulimeni amosheka ngekungasebenti kahle. Ngekukala kahle lamanti lakhona etimphandzeni tetitjalo letehlukene, kungasita kugadzeke lokulahlekelwa.
