Frequently Asked Questions

  • How does a septic system installation work?

    Septic system installation begins with site evaluation to assess soil conditions and determine the best system layout. Excavation is performed to place the tank and leach field, followed by inspection and permitting. At Select Excavating & Landscaping, we coordinate all phases to ensure proper function and compliance with Rockingham County requirements.

  • When should you schedule septic pumping?

    Most residential septic systems should be pumped every 2 to 3 years to prevent solids from accumulating and causing system failure. Routine pumping extends system lifespan and maintains proper operation. At Select Excavating & Landscaping, we recommend scheduling based on household size and usage patterns.

  • What's the difference between water lines and sewer lines?

    Water lines carry clean, pressurized water into a home or building, while sewer lines carry wastewater away to a septic system or municipal treatment facility. Each requires different materials, depth, and installation standards. Both are essential components of residential and commercial utility infrastructure.

  • Can you install water systems for multiple homes?

    Yes, water distribution systems can be designed to serve multiple homes, units, or buildings within a single development. These systems include coordinated trenching, piping, and connections built to meet engineering and inspection standards. At Select Excavating & Landscaping, we have experience installing scalable community water systems across Rockingham County.

  • What affects the cost of septic system replacement?

    Cost depends on soil conditions, system size, site access, and the type of leach field required. Properties with challenging terrain or strict permitting may require additional excavation or engineering. At Select Excavating & Landscaping, we provide straightforward estimates after evaluating your site in Rockingham County.

  • What are the benefits of upgrading old water lines?

    Upgrading old water lines improves water pressure, reduces the risk of leaks, and eliminates contaminants from corroded pipes. Modern materials last longer and meet current safety and building standards. Replacement also prevents costly emergency repairs and property damage.

  • Do you need permits for sewer line installation?

    Yes, sewer line installation typically requires permits and inspections to ensure compliance with local and state regulations. Proper permitting protects water quality and ensures safe connections to septic or municipal systems. At Select Excavating & Landscaping, we coordinate all required inspections and documentation throughout Rockingham County.

  • What's the biggest mistake people make with septic systems?

    The most common mistake is neglecting routine pumping, which leads to solids buildup, drain field failure, and expensive repairs. Regular maintenance extends system life and prevents backups. At Select Excavating & Landscaping, we recommend pumping every 2 to 3 years depending on usage.

  • How long does a water distribution system last?

    A properly installed water distribution system using quality materials can last 50 years or more with minimal maintenance. System longevity depends on material choice, installation quality, and soil conditions. At Select Excavating & Landscaping, we build scalable systems designed for long-term performance in New Hampshire developments.

  • What type of excavation is needed for utility work?

    Utility excavation involves precision trenching to place water lines, sewer lines, or septic components at the correct depth and grade. Professional-grade equipment minimizes property disruption and ensures accurate placement. At Select Excavating & Landscaping, we adapt our excavation methods to Rockingham County terrain and project requirements.

  • Can a septic system be installed in winter?

    Septic installation in winter is possible but more challenging due to frozen ground and limited inspection availability. Soil conditions and permitting timelines may delay the process. At Select Excavating & Landscaping, we recommend planning installations during warmer months for optimal efficiency and compliance in New Hampshire.
