The project consist in the construction of “phase 1” of a new lagoon-based wastewater treatment system with a 30 lps (0.685 MGD) capacity and lift station, construction of two wastewater conveyance lines and the expansion of the wastewater collection system (WWCS). This new facility, will replace the existing 16 lps (0.365 MGD) WWTP, which is overloaded and fails to meet effluent quality standards;the new WWTP will be located 2.36 km (1.46 miles) northwest of the current facility and will discharge to Rio Sonoyta, and a later possible use for agriculture irrigation. The wastewater conveyance lines will carry Sonoyta’s wastewater by gravity to the new lagoon treatment system. The expansion of the WWCS will include new service to benefit the following settlements or colonias: Ejido Hombre Blanco, Ejido Pápagos, and Barrio Las Botellas. Approximately 720 new residences will receive first time service.
