1. Ammaan ah oo aan sun ahayn
Dhuumaha leexleexadu waxay ka samaysan yihiin caag heerka ethylene propylene copolymer, kaas oo hubin kara badbaadada, suntan la'aanta iyo iska caabbinta daxalka wanaagsan marka la isticmaalo.
2. Xaaladda socodka laminar ee tuubada leexleexdu waa wanaagsan tahay, iyo dejinta walxaha laguma qasi karo qulqulka qulqulaya marka la daaweynayo wasakhda.
3. Awood xoog leh oo lagula tacaalayo roobabka
Awoodda haanta seedimentation-ka ee janjeera waa 3-5 jeer ta haamaha wasakhda kale.
4. Waxay ku habboon tahay mashaariicda biyo-mareenka
Marka dhererka tuubada leexleexdu ay tahay 1 mitir, culayska la saarayo waxa loo qaabeeyey si waafaqsan 3-5 tan/m2·h. V0 waxa lagu xakameynayaa inta udhaxaysa 2.5-3.{6}} mm/s, tayada wasakhda ayaa wanaagsan
