Project Overview

MH Civil Constructors partnered with the City of Sundown and Parkhill to deliver a New Wastewater Treatment Plant, a comprehensive infrastructure replacement designed to secure the community’s utility future. Moving beyond simple repairs, the City utilized the Clean Water State Revolving Fund to finance a complete system overhaul. The scope featured the construction of a new facultative lagoon, an effluent storage pond, a high-efficiency lift station, and a modern irrigation-based effluent handling system, alongside the formal closure of the City’s outdated treatment facilities.

The Problem

• System Obsolescence: The existing wastewater plant had reached the end of its functional life, requiring a full-scale replacement rather than incremental maintenance.
  
• Environmental Compliance: To meet modern standards and secure state funding, the City needed a system capable of sophisticated effluent handling via irrigation.
  
• Long-Term Reliability: As a primary municipal service, the wastewater system required a design that ensured operational resilience for decades to come.
  
• Decommissioning Needs: The project required a seamless transition from the old plant to the new facility, including the safe and permanent closure of existing infrastructure.

Our Solution

MH Civil managed the end-to-end construction of the new treatment facility, beginning with the installation of a new lift station and 3,268 linear feet of 6-inch PVC force main. The core treatment capacity was established through the placement of over 184,771 square feet of high-performance pond liner and geotextile for the facultative lagoon and storage ponds. To manage effluent, the team constructed a specialized irrigation structure equipped with integrated pumps, electrical controls, and flow meters, supported by 1,204 linear feet of irrigation line and a “Big Gun” irrigation system.

The scope extended to vital site improvements, including the construction of access roads, culverts, and over 2,300 linear feet of security fencing. Throughout the process, MH Civil coordinated the transition of services, ensuring the new plant was fully integrated into the City’s grid before finalizing the closure of the previous facility.

The Results

The project was successfully delivered to a fully operational status, closing out at a final value of $2,515,493.60—significantly under the original contract price through disciplined management and change-order efficiencies. By completing this project within the rigorous requirements of the State Revolving Fund, MH Civil provided the City of Sundown with a modernized, compliant, and highly efficient wastewater solution. Local reporting confirmed the plant’s successful transition into active service, marking a major milestone in the City’s effort to provide reliable, long-term utility service to its residents.

Project Overview

MH Civil Constructors executed the North Water Treatment Plant (WTP) Improvements Project No. 3 and the South WTP Uprating Improvements for the City of Lubbock. This dual-facility modernization program, totaling $15.72 million, represents a significant investment in the region’s water security. The project encompassed critical upgrades to the North WTP—a regional hub serving Lubbock and six neighboring cities—and the South WTP, a membrane-based facility processing surface water from Lake Alan Henry.

The Problem

• Regional Dependency: As a primary regional asset serving multiple member cities, the North WTP required modernized infrastructure to ensure uninterrupted service for a broad population.
  
• Capacity Bottlenecks: Rapid local growth necessitated an “uprating” of the South WTP to increase permitted treatment capacity to approximately 19–20 MGD.
  
• System Modernization: Aging clarifiers, backwash waste storage basins, and pump stations required technological and structural upgrades to maintain operational efficiency.
  
• Operational Continuity: All improvements had to be executed within a live-facility environment, requiring precise coordination to avoid any disruption to the City’s daily water supply.

Our Solution

MH Civil managed a complex, live-facility improvement program that integrated heavy civil construction with sophisticated process mechanical work. At the North WTP, the scope focused on the backwash waste storage basin and pump station, as well as clarifier-related improvements and extensive yard piping. Simultaneously, the team implemented process upgrades at the South WTP—including additional plate settlers and membranes—specifically designed to uprate the facility’s treatment output. To ensure long-term reliability, the project integrated modernized electrical systems, high-performance slide gates, and advanced SCADA programming, providing the City with a fully modernized control interface across both plants.

The Results

The project was successfully completed with a final contract value of $15,719,127, effectively achieving the City’s goal of raising the South WTP capacity to 20 MGD. This modernization effort has secured the 75 MGD output of the North WTP, providing long-term reliability for both Lubbock and its regional partners. By delivering these high-consequence upgrades on time and through disciplined change-order management, MH Civil has strengthened the infrastructure that supports the City’s future growth and its commitment to providing high-quality water from Lake Alan Henry.

Project Overview

Archer City’s water infrastructure had long been a concern for residents and local officials, with multiple reports from local newspapers highlighting the need for urgent upgrades. Aging equipment, inconsistent water quality, and increasing demand led to growing public frustration. News articles cited issues such as outdated filtration systems, frequent service disruptions, and rising operational costs as major challenges for the city. To address these concerns, the city approved the development of a 1.0 MGD (Million Gallons per Day) water treatment plant, ensuring safe, reliable, and efficient water delivery for its residents. MH Civil Constructors, Inc. was selected to lead the construction due to its strong reputation for professionalism, quality work, and timely project delivery.

The Problem

• Aging Infrastructure: The existing raw water transmission pipeline had surpassed its useful lifespan, leading to frequent breakdowns and costly repairs.
• Capacity Constraints: The original pipeline was no longer sufficient to meet the city’s growing water demands.
• Water Quality Concerns: Old infrastructure posed potential risks to water quality, necessitating immediate improvements.

Our Solution

Selected for their proven track record, MH Civil Constructors, Inc. delivered a 1.0 MGD water treatment plant designed for long-term efficiency and regulatory compliance. The project featured comprehensive ground-up construction, including a new administration building, Parshall flume, twin clarifiers, and a high-performance filter building.

The scope also integrated advanced chemical feed systems, ground storage tanks, and a high service pump station to ensure reliable capacity. Through meticulous planning and proactive coordination, MH Civil completed the facility with change orders totaling less than 1% of the original contract value.

The Results

The Archer City Water Treatment Plant project successfully transformed the city’s infrastructure, expanding capacity to 1.0 MGD while eliminating service disruptions and stabilizing water quality. By replacing aging equipment with energy-efficient systems, the city achieved a 25% reduction in energy usage and exceeded all regulatory standards.

The project was completed ahead of schedule and maintained high public trust through transparent communication and stakeholder engagement. Ultimately, this investment underscored the value of proactive planning and quality construction, delivering a reliable, sustainable utility built to last.
