[Shuangbei restaurant store water and electricity CapEx] Open restaurant water and electricity piping mines! Grease trap (oil trap) regulatory declaration, high-power three-phase 220V/380V electricity and electrostatic smoke exhaust system planning

The core lifeline of commercial property investment and catering, water and electricity

In popular business districts in the greater Taipei area (such as Taipei City East District, Zhongshan Business District, and New Taipei Banqiao Business District), leasing or acquiring first-floor stores to open restaurants, handcrafted beverage shops, or coffee shops is the first choice for many entrepreneurs and commercial real estate investors. However, the requirements for water, electrical and mechanical systems (MEP) in the catering industry are vastly different from those in general retail stores or residential buildings! After many people signed a contract to sell the store, they discovered that the amperage of the distribution box was seriously insufficient to power the commercial combi steamer, that the government had fined them continuously for not installing a "grease interceptor (oil trap)" that complied with environmental regulations, or that the noise from the oil fume exhaust duct was jointly reported by the residents above and ordered to close the business. To successfully operate a catering store in Shuangbei, you must understand the three core plans of water, electricity, electricity and water in the early stages of decoration.

Fact check: Environmental Protection Bureau's "Water Pollution Prevention and Control Law" and "Grease Interceptor" installation rigid specifications

Wastewater produced in catering kitchens contains a large amount of grease and kitchen residue. If high-temperature hot oil is discharged directly into the ditch, the grease will condense and agglomerate on the pipe wall, causing serious blockage of the building's public drainage pipes and roadway side ditches and the outbreak of stench. According to the "Taipei City Building Grease Interception Equipment Installation Standards" and the New Taipei City Environmental Protection Bureau regulations:

• Rigid standards for the installation of grease traps: Any commercial store that involves food washing, frying, and frying must install a qualified "stainless steel three-level grease trap (Grease Trap)" at the kitchen drainage outlet. Wastewater needs to go through "floating oil isolation, residue filtration, and three-stage sedimentation" before it can be discharged to public sewage sewers.
• Violation penalties and suspension of business: If grease traps are not installed or are not cleaned regularly, resulting in grease overflowing into ditches, the Environmental Protection Bureau may impose a fine of NT$ 30,000 to NT$ 3,000,000 in accordance with the Water Pollution Prevention and Control Act, and may continue to impose penalties on a case-by-case basis until improvements are made!

High-power catering electricity: three-phase three-wire 220V / three-phase four-wire 380V application process

The operating electricity consumption of commercial kitchens is extremely staggering (commercial freezers, combi steam ovens, blast freezers, high-power induction furnaces, multi-connected commercial air conditioners, etc.), and the traditional single-phase 110V/220V 100A distribution box is completely unable to bear the load:

1. Application for three-phase power expansion (3-Phase Power): It is necessary to hire a qualified Class A water and electricity contractor to apply for "three-phase three-wire 220V" or "three-phase four-wire 380V/220V" commercial dedicated power from Taipower (Taipei City Business Office or New Taipei City Business Office).
2. Reorganization of main distribution box and distribution box: Configure high amperage NFB circuit breaker from Shilin Electric or TECO, and strictly plan the current load balance of each phase (R phase, S phase, T phase) to prevent single phase overload tripping.
3. Independent electromagnetic contactor and emergency cut-off switch: High-power kitchen heating equipment should be equipped with electromagnetic contactor and overload relay, and an emergency power-off switch (EPO) should be set at the exit to ensure fire safety.

Oil fume and noise protection: static machine and air duct silencer project

Residences and shopping malls are closely adjacent to each other in the Greater Taipei area, and restaurant fumes and air duct noise are the hardest hit areas of community disputes:

• Electrostatic Precipitator: The kitchen air duct must pass through an electrostatic machine for high-voltage electric field ionization and adsorption of oil fume. The oil fume removal rate must reach 90% or more, and an activated carbon deodorizing box must be installed to filter out odors.
• Duct silencer box and variable frequency fan: The smoke exhaust fan should use a variable frequency motor, and be wrapped with 50mm thick high-density glass wool/muffler cotton at the turning point and outlet end of the air duct to ensure that the boundary noise meets the "Noise Control Act" standard of less than 50 dB in commercial areas at night.

Catering store water and electricity decoration asset expenditure (CapEx) budget abacus

When commercial real estate investors and restaurant owners evaluate store decoration CapEx, the water, electricity, and electricity budget estimates are as follows:

Conclusion: Use compliant mechanical and electrical engineering to protect the value of commercial assets

The plumbing and electrical engineering of catering stores is by no means as simple as "power and drainage". Compliant grease interceptors, sufficient, stable and safe three-phase power systems, as well as high-standard electrostatic oil fume purification and air duct noise reduction projects are the only passes for catering stores to operate stably in the long term and avoid government fines and community reports. When investing in commercial real estate or disposing of leases, putting mechanical and electrical compliance first is the smartest strategy to maximize property value and achieve high rates of return.

New knowledge on air-conditioning power consumption and Taiwan climate maintenance regulations in recent years (2025-2026 current situation)

With the high temperatures in summer breaking historical records and the adjustment of electricity price structure in recent years, the latest statistics from the Energy Administration of the Ministry of Economic Affairs show that air-conditioning equipment accounts for more than 47% of residential electricity consumption in summer. Many people mistakenly believe that if the air conditioner is not cold, they only need to "replenish the refrigerant." However, in fact, refrigerant is not naturally consumed during normal operation in a closed circuit. If the refrigerant is insufficient, it means that there are micro leaks in the copper pipes or joints. Simply replenishing the air conditioner will only treat the symptoms but not the root cause. Refrigerant leakage will aggravate the high temperature overload of the compressor and shorten its service life.

According to Taiwan's standard operating specifications for air-conditioning projects, it is recommended that professional technicians with a refrigeration and air-conditioning decoration technician license perform "full machine high-pressure water washing and evaporator deep sterilization" every 1 to 2 years for detached air-conditioning indoor units. Especially in the humid summer in the Shuangbei Basin, the air drum and water collection tray are easy to breed black mold and jelly-like biofilm. This is also the main reason for the sour smell in the air-conditioning outlet and the backflow of the drainage pipe. Regular maintenance can maintain CSPF (Air Conditioning Seasonal Performance Factor) level one energy efficiency level, which can save an average household 15% to 20% of air conditioning electricity bills every year.

Autonomous simple maintenance vs professional maintenance safety red line

• Homeowners can do by themselves: Remove and clean the nylon filter regularly every 2 to 3 weeks (rinse with clean water and dry in a cool place, do not expose it to the sun to avoid deformation and embrittlement); clean the air outlet blades of the indoor unit with a dry cloth; check whether there is any accumulation of debris within 50 cm around the outdoor unit that hinders heat dissipation.
• Professional technicians must be entrusted according to regulations: Refrigerant pressure testing and leakage repair welding, high-pressure cleaning of indoor unit air drums and aluminum fins with liquid chemicals, reset of the drainage slope of hidden cold water pipes in the ceiling, and 220V dedicated power circuit configuration and leakage circuit breaker replacement.
