In-Ground Gravity Interceptor Installation in New Castle, DE
Larger restaurants and high-volume kitchens often need an outdoor gravity interceptor. These concrete or polyethylene tanks usually range from several hundred to over 1,500 gallons. We excavate, set the tank on a stable base, connect inlet and outlet piping and install manhole risers. Sandy soil drains quickly but can shift and settle, which may stress buried sewer lines and water service pipes over time. We plan excavation equipment around the ground conditions we find on site. A properly installed interceptor can go far longer between pump-outs than an indoor trap.

Smaller establishments or specific kitchen stations in New Castle, DE may benefit from compact under-sink grease traps.

Frequently Asked Questions About Grease Trap Installation in New Castle
The cost of grease trap installation in New Castle, DE varies significantly based on the size, type, and complexity of the system. Small under-sink units might range from $1,000 to $3,000, while large outdoor interceptors requiring excavation can cost anywhere from $5,000 to $20,000 or more.

The cleaning frequency for a new grease trap depends on its size, the volume of FOG produced by your kitchen, and local regulations in New Castle. Typically, grease traps require cleaning every 1 to 3 months. Regular cleaning is essential to maintain efficiency and prevent backups.
We install all common types of grease traps, including gravity grease interceptors, hydro-mechanical grease traps (automatic grease removal units), and compact under-sink grease traps. Our team helps you determine the best system for your commercial kitchen's specific needs and local code requirements.
Yes, commercial grease trap and interceptor installations generally require a plumbing permit and inspection. Some cities also require approval from their pretreatment or wastewater department.
We calculate flow from every connected fixture, including sinks, floor sinks and dish machines. Hydromechanical units are typically rated by gallons per minute, while gravity interceptors are sized by volume and retention time.
That depends on local rules and the trap type. Some programs require dish machines to discharge through the interceptor, while others restrict high-temperature discharge into certain units, so we confirm the requirement before we install.
Installation time depends on the size and complexity of the grease trap. A small under-sink unit might take a few hours, while a large outdoor interceptor could require several days due to excavation and concrete work. We strive to complete installations efficiently to minimize disruption to your business operations.
