Our Facilities

Las Rusias Water Treatment Plant

This is a standard surface water treatment plant in Los Indios constructed to process well or surface water provided to customers in Western Cameron County. It treats well water from six (6) wells and has a capacity to produce 1,500 GPM or approximately 2.1 million gallons per day of treated water. The plant total cost was $2,030,000.00. The plant has been in operation since in 1995. Improvements to the treatment process are scheduled to be performed in 2012. 

Rangerville Road Booster Station

This is a booster station located on FM 1479 (Rangerville Road) at the intersection with FM 800 south of Harlingen. It is used to pump water purchased from the City of Harlingen to supplement the Las Rusias WTP in times of high water demands by customers in the Cameron County service area. It has a pumping capacity of 600 GPM or approximately 0.85 million gallons per day. This booster station was the main pumping  station for the Cameron County service area prior to the construction of the Las Rusias Water Treatment Plant in 1995. It is now used seasonally during the summer months.

Progreso RO Water Treatment Plant

This is a micro filtration reverse osmosis water treatment plant in Progreso to process brackish well water to improve the quality of the water provided to customers in the cities of Progreso and Progreso Lakes. It treats well water from three (3) wells around the plant and has a capacity to produce 700 GPM or approximately 1 million gallons per day of treated water. The project total cost was $2,030,000.00 of which $1,250,000.00 was a grant and $780,000.00 was a loan. The plant was completed on May 21, 2010 and went into full operation on July 1, 2010.

Progreso Lakes Water Booster Station

This is a booster station in Progreso Lakes used to pump well water to customers west of the cities of Progreso and Progreso Lakes. It pumps water from three (3) wells and has a pumping capacity of 2,500 GPM or approximately 3.6 million gallons per day. The station was constructed in 2000.

Progreso Wastewater Treatment Plant

This was MHWSC's first sewer plant constructed in 1980. Located northeast of Progreso, it originally was a facultative lagoon pond system that used biological processes to treat the wastewater for discharge into the Arroyo Colorado. It was enlarged (from 200,000 GPD to 400,000 GPD) and improved (added created wetland treatment) in 1990. A new extended aeration mechanical wastewater treatment plant was constructed in 2011 to replace the existing biological pond treatment system, to increase the treatment capacity from 400,000 GPD to 750,000 GPD, and to improve the quality of the treatment of the wastewater in order to produce a cleaner discharge into the Arroyo Colorado. The construction of the new plant was started in November of 2010 and was completed in March 2012 with the decommissioning of the old pond system.

Balli Road Wastewater Treatment Plant

This is an extended aeration mechanical wastewater treatment plant located on Balli Road just west of South Tower and south of the City of Alamo. It has a capacity for treating 510,000 gallons per day (GPD) of wastewater from the colonia areas south of Alamo. The plant total cost was $2,030,000.00. The plant has been in operation since in 2000.

Joines Road Wastewater Treatment Plant

This is an extended aeration mechanical wastewater treatment plant located on Joines Road just west of FM 732 and south of the City of San Benito. It has a capacity for treating 510,000 gallons per day (GPD) of wastewater from the colonia areas south of San Benito and around La Paloma. The plant total cost was $2,030,000.00. The plant has been in operation since in 2000.

Lagoon System Water Treatment Plants

Military Highway has four non-discharge lagoon sewer treatment plants located in Santa Maria, Los Indios, La Paloma, and San Pedro. These plants utilize biological treatment processes to treat the wastewater. The effluent is used to irrigate grasslands with the plant confines. These plants were constructed using federal funds from the US Department of Agriculture in conjunction with the respective collection systems to address specific colonia needs.  

Wastewater Collection Systems

All existing sewer collection systems operated by Military Highway WSC have been installed under projects funded by the United States Department fo Agriculture. All of these projects were developed to address specific colonia needs. All existing homes within these projects were given the opportunity to connect to the system as part of these projects at the time of the project. All new requests within these project area boundaries are allowed to connect to these systems with the cost of connection paid by the requesting party. All new developments able to connect to these systems are allowed to connect to these systems with the cost paid by the developer. MHWSC will provide estimates for any new sewer connections upon request.

All properties outside of these system areas can not be serviced without the development of a supporting system. Some type of new improvement project to be funded by the state or federal government must be developed. These new projects must meet funding agency guidelines.

In areas where there is no available combined sewer systems, alternative methods will be considered in order to provide sewer disposal. Pressure pump systems can be allowed where connection to a existing force main is available. The installation and maintenance of the pressure pump system is the responsibility of the property owner. Military Highway WSC will provide a mainline tap with check valve assembly for the consumer to use to connect to the force main. The property owner can install an approved pumping system on the property and connect the system to MHWSC’s tap. A service fee is assessed to treat the sewer from this system. MHWSC can provide estimates for the installation and cost of the equipment used in these sewer pressure pumping systems upon request. Ownership of these systems remain with the property owner.

On-site septic systems are also allowed as long as they meet county regulations in terms of the design and construction. These septic systems may be the only method available for the proper owner to use for the sanitary disposal of wastewater.
