重新注满 meaning in Chinese

re-fill

In the same way that the water in pond 20 has to be replaced after the departure of the wintering ducks , the water in the waterfowl collection also needs to be drained in early summer and the pond in the collection replaced by cleaner rainwater in late summer
正如20号水池需在越冬水鸭离开后换水一样，工作人员亦须在初夏时份把水禽养殖池的池水抽乾，方便仲夏雨水重新注满养殖池。
