【正文】 6 《省政府關(guān)于全省縣級以上集中式飲用水水源地保護(hù)區(qū)劃分方案的批復(fù)》（蘇政復(fù)〔 2020〕 2 號） 《江蘇省地表水（環(huán)境）功能區(qū)劃》 江蘇省水利廳、環(huán)保廳 第三節(jié) 可行性研究的編制原則 根據(jù)縣城總體規(guī)劃，結(jié)合用水現(xiàn)狀和供水規(guī)劃，本著對水資源統(tǒng)一規(guī)劃和合理開發(fā)的原則，確定供水范圍和供水規(guī)模； 注重可行性 ，著眼合理性，與縣城各階段建設(shè)目標(biāo)和規(guī)模相適應(yīng)； 保證規(guī)劃區(qū)內(nèi)的供水設(shè)施完善，滿足用戶用水要求，從而加快鄉(xiāng)村發(fā)展，提高農(nóng)民生活水平； 合理利用現(xiàn)有供水設(shè)施，完善供水系統(tǒng)，盡可能減少工程投資，降低供水成本； 供水水質(zhì)達(dá)到《國家生活飲用水衛(wèi)生標(biāo)準(zhǔn)》（ GB574985）及《城市供水水質(zhì)標(biāo)準(zhǔn)》（ CJ/T2062020），保障居民用水安全； 貫徹節(jié)能的原則，以先進(jìn)、適用、合理、經(jīng)濟(jì)為原則，降低運(yùn)行成本，改善勞動環(huán)境，提高管理水平，發(fā)揮經(jīng)濟(jì)效益與社會效益； 保證配水管線最高日最高時最不利點水壓不低 于 20 米； 合理選用管材，使之能夠在保證供水安全性的同時，盡可能地經(jīng)濟(jì)耐用。 .................................................... 11 第三章 項目所在地概況 ..................................................... 13 1. 自然條件
