<![CDATA[Clean water supply in rural areas frequently encounters technical distribution problems and seasonal discharge fluctuations, requiring adaptive institutional governance. This study aims to analyze the development strategy of the Suko Mukti Village-Owned Enterprise (BUMDes) within the "Sumber Mukti" village clean water service unit in Sukorejokulon Village, Kalidawir District, Tulungagung Regency, along with its driving and constraining factors. A descriptive qualitative method with a case study design was employed. Data were gathered through field observation, documentation, and in-depth interviews with eight key informants selected purposively. The results indicate that enterprise development is pursued through local spring optimization, distribution network rehabilitation, volumetric tariff formulation, and institutional maintenance coordination. This initiative is supported by continuous water discharge, village government capital equity, and active community participation. Nonetheless, the enterprise still faces operational challenges, notably seasonal discharge drops during prolonged dry seasons and billing payment delays among several consumers. ABSTRAK Penyediaan air bersih di perdesaan sering kali menghadapi kendala teknis jaringan dan fluktuasi debit musiman, sehingga memerlukan tata kelola kelembagaan yang adaptif. Penelitian ini bertujuan untuk menganalisis strategi pengembangan Badan Usaha Milik Desa (BUMDes) Sukomukti pada unit usaha PAM Desa layanan air bersih (Sumber Mukti) di Desa Sukorejokulon, Kecamatan Kalidawir, Kabupaten Tulungagung, beserta faktor pendukung dan penghambatnya. Metode yang digunakan adalah kualitatif deskriptif dengan pendekatan studi kasus. Pengumpulan data dilakukan melalui observasi lapangan, dokumentasi, dan wawancara mendalam terhadap delapan informan kunci yang dipilih secara purposif. Hasil penelitian menunjukkan bahwa pengembangan unit usaha dilakukan melalui optimalisasi sumber mata air lokal, rehabilitasi jaringan transmisi dan distribusi, penataan sistem tarif berbasis volume, serta peningkatan koordinasi pemeliharaan. Keberhasilan program ini didukung oleh ketersediaan debit mata air alami, komitmen penyertaan modal pemerintah desa, serta partisipasi aktif warga. Meskipun demikian, unit usaha masih dihadapkan pada tantangan penurunan debit saat kemarau panjang dan tunggakan iuran bulanan dari sebagian kecil konsumen. ]]>
