Embracing vacuum excavation for rural water line repair: A BCWA case study

Every day, municipalities and rural water associations contend with the complex task of maintaining and repairing underground water and sewer pipes. This task is increasingly challenging due to urbanization and the presence of other buried utilities, like electrical and fiber optic lines. The Bear Creek Water Association (BCWA), Mississippi, is one such organization that has turned to vacuum excavation for the repair of rural water lines.

Innovative solutions with vacuum excavation

BCWA, the largest rural water association in Mississippi, noticed an uptick in water and sewer line repairs as the region urbanized. The traditional reliance on backhoe loaders and mini excavators risked causing additional damage to the increasing number of underground utilities. The solution? Vacuum excavation.

Vacuum excavation, also known as soft digging, uses pressurized water to loosen soil, which is then vacuumed up into a debris tank. It offers a precise digging method that minimizes ground disturbance and helps reduce the risk of damaging other utilities.

In 2017, BCWA purchased a Vermeer VX50 vacuum excavator equipped with a 4-in (10.2-cm) suction hose, a 1,025-cfm (29-m³/min) blower, and a 500-gal (1,893-L) debris tank. This model is well-suited for the yazoo clay ground conditions in Madison County and the average depths of buried utilities.

Vacuum excavation for underground utility repair

When a water line leak occurs, BCWA starts by calling the utility locating service. The team often uses the VX50 for areas with multiple underground utilities. Vacuum excavation helps BCWA efficiently excavate without damaging other utilities and reduces the risk of service disruptions. It also minimizes the size of the repair working area and maintains a cleaner site.

This method has proven more efficient and less physically demanding than traditional methods, reducing the need for manual labor with shovels. It also aligns with BCWA’s commitment to delivering cost savings to its customers.

Value of vacuum excavators in the equipment fleet

While BCWA still uses backhoes and mini excavators for many repairs, the Vermeer vacuum excavator has earned its spot in the equipment fleet. It’s regularly employed for potholing utilities and excavating areas where traditional digging methods are challenging.

According to Nolan Williamson, BCWA’s general manager, the VX50 does not replace the mini excavator but serves a different purpose. “They are two complementary pieces that help us find the best, quickest and cheapest way to make a repair.”

Growing need for vacuum excavators

With the increasing number of utilities being placed underground, Williamson believes a vacuum excavator should be part of every municipality’s and rural water association’s fleet.

The BCWA team has also recognized the value of vacuum excavators for routine maintenance tasks, such as cleaning around water valves. In fact, a few years ago, when Jackson, Mississippi’s water system experienced a major outage, BCWA deployed its Vermeer vacuum excavator crew to assist in locating water valves in the affected areas and restoring the water supply.

“We have gained valuable experience since investing in our VX50. These machines are not limited to HDD contractors; anyone involved in digging around utilities can benefit from having a vacuum excavator in their fleet,” Williamson concluded.

In the era of increasing urbanization and complex underground utility networks, vacuum excavation is proving to be an invaluable method for water system repair and maintenance.
