Backhoe digging a dich

All you need to do is give Lorenz a call and let us worry about the rest. We will call in for locates, bring the backhoe, the dump truck, and the materials. Here are just some of the ways our excavation service can meet your needs.

  • Digging of trenches for new water, sewer and electrical service lines
  • Digging and repair of broken or damaged water and sewer lines, including emergencies
  • Backfilling of trenches with dirt and/or gravel
  • Digging for capping off of existing water and sewer lines
  • Final grading and yard repair

    Backflow is the reversal of the flow of water or mixtures of water and other unwanted substances from any source (such as used water, industrial fluids, irrigation systems, gasses, etc.) into the distribution water mains or pipes of the water system.

    Water distribution systems are designed to flow in one direction from the main to the customer. When the direction of flow is reversed due to pressure differences, (such as fire fighting efforts, a water main break, or consumer high side pressure), backflow can allow contaminants to enter the drinking water system through cross-connections.

    Backflow prevention protects drinking water from minor, moderate, and severe hazards. A backflow prevention device is used to protect water supplies from contamination or pollution and should be checked annually to ensure proper function.

    Let one of our Certified Backflow technicians test your prevention system.
