供水方面:

年均向晉江東溪調(diào)水4.4億立方米；年均可增加對德化城區(qū)供水3715萬立方米，使中遠(yuǎn)期德化城區(qū)的供水保證率由49.3%提高到97.4%，從而解決德化城區(qū)的中遠(yuǎn)期水資源供需矛盾。

防洪方面:

通過226萬立方米水庫防洪庫容(相應(yīng)汛限水位為641.2米)，使德化城區(qū)防洪能力由現(xiàn)狀20年一遇提高到30年一遇，遠(yuǎn)期可達(dá)50年一遇(相應(yīng)汛限水位439.75米、防洪庫容499萬立方米)。

發(fā)電方面:

彭村水庫壩后電站裝機(jī)容量7.4兆瓦，年度發(fā)電量3065萬度，還可增加龍門灘水庫下游梯級(含山美水庫)電站年發(fā)電量2780萬度。

To jinjiang creek water diversion east 440 million cubic meters per year; An average increase of dehua city 37.15 million cubic meters of water supply, make long-term dehua urban water supply assurance rate from 49.3% to 49.3%, thus solve the contradiction of supply and demand of water resources is the long-term dehua city.

By 2.26 million cubic meters of the reservoir flood control capacity of corresponding level (641.2 meters), make the dehua urban flood control ability by the status quo once every 20 years to 30 years, the forward to once every 50 years.(Corresponding level of 439.75 m, flood control capacity of 4.99 million cubic meters).

Peng village after the reservoir dam power station installed capacity of 7.4 mw, the annual output of 30.65 million degrees, also can increase the longmen beach reservoir downstream cascade (including mountain reservoir) power plant generating 27.8 million degrees.
