Belum optimalnya pelayanan air minum khususnya di PDAM Kabupaten Tangerang dikarenakan pelayanannya tidak efisien. Saat ini PDAM sebagai penyelenggara penyedia air minum berfungsi sebagai operator dan regulator dan belum adanya kebijakan Pemerintah Pusat dan Daerah mengenai ide pembentukan Badan Regutator sebagai upaya mengatasi terjadinya tumpang tindih antara pembuat kebijakan/regulator dengan pelaksana/operator. Selain dengan kondisi yang ada belum menarik minat investor dalam penyedian air minum.Penelitian ini menggunakan tipe penelitian deskriptif dengan metode komunikasi berdasarkan wawancara terbuka penarikan sampel menggunakan Judgment Sampling (Purposive Sampling) dengan pengambilan sampel dari suatu populasi di pelanggan PDAM Kabupaten Tangerang, karyawan Departemen Permukiman dan Prasarana Wilayah, karyawan PDAM kabupaten Tangerang dan Investor air minum.Dari hasil penelitian ini, dapat di dapat hal-hal sebagai berikut : bahwa Pemerintah akan mendukung ide pembentukan Badan Regulator dan dari hasil penelitian pelanggan air minum juga mendukung ide tersebut. Fungsi utama Badan Regulator adalah sebagai mediator apabila terjadi perselisihan antara pemerintah, pelanggan dan investor termasuk di dalamnya penetapan tariff, mekanisme subsidi silang, perbaikan distribusi, pelayanan serta administrasi yang baik. Dengan adanya Badan Regulator akan menarik minat investor. Pengaturan penyelenggaraan pada masa transisi difokuskan pada pengalihan kewenangan secara bertahap.
