Grease Holding Capacity
We often get asked how much grease our grease traps and interceptors hold. We will look at our 1,500 gallon HS20 traffic rated grease trap and answer that question for this tank. The amount of grease held by a precast concrete tank is surprising! [More]

Keeping Grease in the Tank
There are two main ways to prevent grease from escaping a grease trap/interceptor and entering a municipal system - priming the tank and using a tank configuration with both a ninety in the partition wall and an outlet tee. [More]

Butyl Sealant in the Joint
Grease traps or grease interceptors are tanks used to separate grease and water to prevent grease from entering municipal sewer systems, which eliminates costly repairs and clean out operations. There are several ways to prevent grease from escaping a grease trap/interceptor and entering a municipal system - using a tank configuration with both a ninety degree elbow in the partition wall and an outlet tee and/or priming the tank with clean water.

Inflow and Infiltration
Watertight tanks are generally overlooked as a solution to inflow and infiltration (I&I) problems in municipal and decentralized wastewater systems. The use of watertight tanks can dramatically reduce treatment costs, reduce overflow events, and help contain the ever increasing problem of inflow and infiltration. An ideal scenario would show the treated sewage effluent to be less than the total purchased water. Watering yards, washing cars, consumption, etc., all dispose of water outside the sewage collection system and account for effluent wastewater being less than purchased water. [More]

Analyse de l’afflux et de l’infiltration par le couvercle d’une fosse septique
Les fosses septiques étanches ne sont généralement pas prises en compte dans les problèmes d’afflux et d’infiltration (I&I) par les systèmes municipaux et délocalisés de traitement des eaux usées. L’utilisation de fosses septiques étanches peut dramatiquement réduire les coûts de traitement, les regorgements, et aider à contenir les problèmes d’afflux et d’infiltration qui augmentent de jour en jour. Le scénario idéal devrait montrer des effluents d‘eaux d’égout traitées comme étant inférieurs au coût total de l’eau. Or, l’arrosage des pelouses, le lavage des voitures, la consommation des ménages, etc rejettent l’eau usée en dehors du système de collecte des égouts et expliquent ainsi que le gaspillage d’effluents soit inférieurs au coût de l’eau.

Maximum Design Capacity
Often it is necessary to install a precast concrete grease interceptor or septic tank in a vehicular traffic area. The temptation for any tank manufacturer is to use existing molds to produce the tank; and this temptation is very real because investment in new molds specifically for traffic-rated applications is costly. Many factors add to the expense of a new traffic-rated product and new molds are just the beginning of problems and extra cost relating to traffic-rated tanks. [More]

The Real Dirt on Isolation Slabs
Engineering analysis proves that isolation slabs do not protect underground tanks from vehicular loads and, in fact, serve to increase loading on the underlying tank.

Public Utility Infrastructure Improvements through Enhanced Grease Trap Specifications
Wastewater utilities are experiencing increased pressure to maintain cost-effective operations while ensuring compliance with state and federal regulations. Overflows from manholes and overloads of wastewater treatment facilities often lead to regulatory non-compliances, system outages, undesired repair costs, and tarnished public image of the utility. Pervasive system problems can lead to regulatory intervention and forced remediation programs. Remediation efforts often lead to increased costs and higher rates, as well as public relations problems with utility customers. [More]
