Ikimenyetso cya metero

*Ikimenyetso gicapwa buri metero 1;

● Ibara ry'ikimenyetso ni umweru, ariko niba ari ngombwa ko ugishyiramo ikimenyetso, ikimenyetso cy'umuhondo kigomba gucapwa gishya ahandi hantu.
● Hari igihe ibimenyetso by'uburebure bitazwi neza biremewe iyo ibimenyetso byombi biri hafi aho bisobanutse neza;
● Impera zombi z'insinga zifunze imipfundikizo y'impera ishyushya kugira ngo amazi adakwirakwira.

Gupakira no Gushyiramo Ikimenyetso

Gupakira

● Buri burebure bw'insinga bugomba gushyirwa ku gikoresho cya pulasitiki.

● Uburebure bw'ingoma: Uburebure busanzwe bw'ingoma ni 3000m±2% cyangwa igishushanyo mbonera nk'uko umukiriya abibaza;

Gushyira ikimenyetso ku ngoma (ikarita ikoreshwa hakurikijwe ibisabwa mu bisobanuro bya tekiniki)

-Izina ry'uwakoze;
-Umwaka n'ukwezi byo gukora;
-Umwambi w'icyerekezo cyo kuzunguruka;
-Imbere y'insinga igaragaza umwambi w'inyuma;
-Ijambo "Umugozi w'ibice by'ijisho";
-Ubwoko n'ingano y'insinga;
-Nomero y'ingoma;
-Uburebure bw'ingoma;
-Uburemere rusange / ubw'umwimerere;
-Inkomoko, Ijambo "BYAKOREWE MU BUSHINWA";
-Icyitonderwa kigaragaza uburyo bukwiye bwo gupakira, gupakurura no gutwara insinga;
- Andi makuru y'abakiriya nka nomero y'amasezerano, nomero y'umushinga, n'aho ibicuruzwa bizagezwa. (niba bikenewe)

Inyandiko zigaragaza insinga

-Icyemezo cyujuje ibisabwa ku musaruro;
-Raporo y'ikizamini.
