I te whanaketanga o te hangarau ngongo mānu, ka taea te tāpiri i ngā mahi maha ki ngā Ngongo Mānu, kia nui ake ai te kaha kawe wai pumau. Nō reira, ka hangaia he paipa mānu motuhake e hangaia ana i ngā ngongo mānu, e hono ana ki te kei o te waka keri.

Ko CDSR te kaihanga tuatahi o ngā Ngongo Rere i Haina. I te tau 1999 anō, i angitu te whakawhanake a CDSR i ngā ngongo rere, i whakamatautauria i roto i te kaupapa keri wai o Shanghai, ā, i riro i a rātou ngā whakamoemiti mai i te kaiwhakamahi whakamutunga. I te tau 2003, i whakamahia ngā Ngongo Rere CDSR i roto i ngā puranga i roto i te kaupapa whakahoki wai o te Tāone o Xingang i te Tauranga Yangshan o Shanghai, hei hanga i te paipa keri wai tuatahi o ngā ngongo rere. Nā te angitu o te whakamahinga o ngā paipa ngongo rere i roto i tēnei kaupapa kua tere te mōhiotia me te whakatairanga whānuitia ngā ngongo rere i roto i te umanga keri wai o Haina. I tēnei wā, ko te nuinga o ngā mīhini keri wai i Haina he Ngongo Rere CDSR kei a rātou.
