Stamford Transmission Line

Project Overview

The City of Stamford identified the urgent need to upgrade its aging raw water infrastructure to ensure a reliable and high-quality water supply for residents. The original raw water pump station and transmission pipeline, dating back several decades, faced frequent failures, capacity constraints, and increasing maintenance costs. To address these challenges, the city launched a comprehensive pipeline replacement and modernization project. MH Civil Constructors, Inc. was selected to lead the construction, bringing their expertise in municipal water line replacement to efficiently execute the project while maintaining the highest quality standards. Their leadership, integrity, and technical expertise were instrumental in ensuring the success of this large-scale project.

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

After a thorough assessment of the system’s deficiencies, MH Civil implemented a phased installation of over 79,000 linear feet of fusible PVC pipe. Selected for its durability and corrosion resistance, the piping included 14-inch DR-25, DR-21, and DR-18 variants strategically chosen to match specific soil conditions and pressure requirements. The modernized line was stabilized with flowable concrete backfill and integrated with new valves and flushing systems to enhance long-term operability.

Beyond the new installation, the team conducted critical leak repairs on existing 18-inch concrete steel cylinder pipes to prevent water loss during the transition. Throughout the expansive scope of work, MH Civil prioritized safety and environmental protection, utilizing detailed excavation plans to safeguard both the workforce and the surrounding community.

The Results

The project delivered immediate results, substantially increasing Stamford’s raw water capacity to meet both current demands and future growth. The new fusible PVC system provides a resilient backbone that has virtually eliminated emergency maintenance calls. By replacing legacy materials with modern engineering controls, water quality now exceeds state and federal standards while ensuring uninterrupted service for residents.

The success of the project earned high praise from Enprotec / Hibbs & Todd, Inc., who commended MH Civil for their proactive problem-solving and professionalism under demanding conditions. Ultimately, the Stamford Transmission Line serves as a model for modern utility management, proving that collaborative planning and high-performance materials can transform failing infrastructure into a reliable, long-term asset.

Archer City Water Treatment Plant

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.

Stephenville Eastside Sewer Interceptor

Project Overview

The City of Stephenville initiated the Eastside Sewer Interceptor – Phase I to address growing wastewater demands, aging infrastructure, and regulatory compliance requirements. This project was designed to expand system capacity, enhance reliability, and replace outdated pipelines to support the city’s long-term development. The total contract value was $21,956,762, with a well-managed budget and change orders accounting for less than 1% of the original contract amount. The project involved significant trenching (25-60′ deep), tunneling, and large-diameter pipe installations to improve wastewater conveyance efficiency.

The Problem

Insufficient Sewer Capacity: Existing pipelines could not accommodate peak flow demands, increasing overflow risks.
Aging Infrastructure: Deteriorating sewer pipes required frequent maintenance and posed structural risks.
Environmental & Regulatory Compliance: Upgrades were necessary to align with state wastewater regulations.

Our Solution

Collaborating closely with city engineers, we implemented a robust plan to replace deteriorating infrastructure with over 16,200 linear feet of large-diameter Fiberglass Reinforced Pipe (FRP). We strategically selected FRP in 30-inch, 36-inch, and 48-inch sizes to ensure superior corrosion resistance and decades of structural reliability.

The project required extensive technical execution, including trenching at depths of up to 60 feet. In high-traffic and environmentally sensitive areas, we utilized trenchless boring and jacking operations with 48-inch to 60-inch steel casings to minimize surface disruption. Additionally, we installed 41 custom FRP manholes designed to withstand fluctuating loads over the long term.

Where the work impacted community spaces, we provided full restoration through trail reconstruction and hydromulching for erosion control. Through diligent safety coordination and constant communication with city stakeholders, we successfully delivered this critical infrastructure upgrade on schedule and within scope.

The Results

The completion of the Eastside Sewer Interceptor marks a turning point for Stephenville’s infrastructure. The upgraded system has increased capacity by 40%, providing a critical buffer for future growth while eliminating the chronic overflow risks that previously threatened regulatory compliance.

By utilizing durable FRP materials, we have extended the system’s operational lifespan by an estimated 50 years, significantly reducing long-term maintenance burdens. This project also serves as a model for fiscal responsibility; with a total contract value of $21.96 million, change orders accounted for less than 1% of the original estimate.

Ultimately, this project highlights the value of strategic execution and premium materials. Stephenville now possesses a resilient, future-ready interceptor system built on a foundation of engineering excellence.
