Guidelines to Property Managers for Formulation of their House-rules to Protect the Environment

2. Management of Communal Facilities
2.1 Communal Domestic STP
  • Maintain and operate the STP to meet the effluent discharge licence conditions.
  • Set up an effective system to monitor the performance and maintenance work of the contractor / operators.
  • Formulate mitigation measures to cater emergency situation of the STP. Ensure operation and maintenance manual of STP easily accessible to concerned personnel.
  • Adopt good housekeeping practices (e.g. clean and non-obstructed walkways, adequate lighting and ventilation) for the STP.
2.2. Communal Grease Trap
  • Maintain and operate the grease trap to meet the effluent discharge licence conditions.
  • Engage registered grease trap waste collector for the regular clearance of grease trap waste.
  • Properly archive cleaning records.
2.3 Refuse Collection Point
  • Direct effluent from cleansing of refuse containers and bins to foul drain.
  • Prevent effluent from discharging to gully traps, e.g. avoid washing containers and bins in open area.
2.4 Refuse Chute
  • Take measures to avoid noise nuisance arising from falling refuse bumping on refuse chute, e.g. placing rubber pad or similar material at the bends to reduce impact noise or avoid using refuse chute during late evening or early morning.
2.5 Swimming Pool
  • Direct effluent from routine operation (e.g. back washing) to foul drain.
  • Direct effluent from annual cleaning to storm drain.
2.6 Pump Room and Associated Piping
  • Adopt measures to avoid excessive noise transmitted through building structure, e.g.
    • proper isolation to minimize structural borne noise;
    • appropriate pressure reducing valve to minimize noise caused by water rushing into water tanks.
  • Conduct regular preventive maintenance to avoid noise caused by defective parts.
  • Employ acoustic consultant/contractor to tackle difficult and complicated noise problems.
2.7 Lift Plant Room
  • Adopt measures such as proper isolation to avoid excessive noise transmitted through building structure.
  • Conduct regular preventive maintenance to avoid noise caused by defective parts.
  • Employ acoustic consultant/contractor to tackle difficult and complicated noise problems.
2.8 Ventilating system (chillers, water cooling towers, exhaust fans, etc.)
  • Carefully locate the system to minimize noise and air pollution nuisance.
  • Conduct regular preventive maintenance to avoid noise caused by defective parts.
  • Install suitable noise barriers, enclosures and silencers to reduce the air-borne noise as appropriate.
  • Install suitable vibration isolation device to abate the structural borne noise as appropriate.
  • Employ acoustic consultant/contractor to tackle difficult and complicated noise problems.
2.9 Emergency Generator
  • Obtain pre-approval from the Director of Environmental Protection Department for installation of generator with nominal fuel consumption exceeding 25 litres per hour of liquid fuel or 1,150 megajoules per hour of gaseous fuel.
  • Conduct testing in hours specified in the approval.
  • Apply proper noise abatement measure to reduce nuisance caused by regular testing of the generators.
2.10 Carparks
  • Ensure adequate ventilation inside indoor carparks.
  • Locate exhaust outlets away from any openable windows or fresh air intakes of the buildings.
2.11 Shopping Mall/Commercial Complex/Club House
  • Properly operate and maintain any communal wastewater treatment facility to meet requirements of the discharge licence.
  • Properly operate and maintain any communal air pollution abatement facility.
  • Properly locate all exhaust outlets so that emissions can be effectively dispersed to avoid nuisance to people in the vicinity.
  • Restrict the use of loudspeakers in shops for attracting attention to their goods to avoid causing nuisance.
2.12 Venue for noise generating entertainment facilities (such as bars, karaoke and discos)
  • Site such facilities away from residential dwellings.
  • Main door preferable be within building structure and open to the interior of the building or screened from residential dwellings.
  • Require installation of double-leaf noise insulation doors and double-glazed noise insulation windows as appropriate for venue with main door or windows opened to the exterior of the building.
  • Require for reducing the music volume during sensitive hours, effective sound insulation and anti-vibration treatments as appropriate.
