Phoenix Precast offers a wide array of products to aid during the maintenance and inspections of septic tanks, distribution boxes and leaching chambers. We also provide items for light duty applications or products that require HS-20 traffic loading requirements.
Light Duty Requirements
For light duty requirements, we recommend access be kept between 6” & 12” below grade to meet NHDES requirements along with protecting the liability of the site contractor. Any access to grade would include a cast iron frame & cover which ensures that the weight of the cover would prevent unauthorized entrance per NHDES 1010.05.e.
Access to grade for precast products that necessitate a hatch for access are available in either round, square or rectangular products and are available with different loading capacities.
