Clear offers a comprehensive range of sewerage and drainage area planning services. Our aim is to provide the highest level of service to our clients through our skilled and experienced team of engineers and technicians using the best modern tools and methods.

Our engineers have extensive professional and technical experience in drainage area planning and in the design, construction and rehabilitation of sewerage systems. Our expertise includes studies ranging from rural village communities to large trunk sewer macro models encompassing complete catchment areas.

These studies cover a range of catchment problems including flooding and the routeing of flood flows, polluting CSOs, in-sewer silt build up, catchment growth and land drainage issues. Through the use of hydraulic models, historical data and operational records, Clear can identify catchment needs and develop outline solutions.
Clear is experienced in carrying out structural and operational analyses, and amalgamating data from a variety of sources to produce robust drainage area plans. We are at the cutting edge of applying new technology to drainage area planning and sewer modelling, and are able to provide innovative solutions to wastewater problems.

Clear have extensive expertise in the following key areas of Drainage Area Planning:

  • Data collection
  • Digital mapping and GIS
  • Survey planning and supervision
  • Model build and verification
  • Hydraulic analysis
  • CSO performance analysis? Infiltration assessment
  • Structural and operational analysis
  • Needs identification and reporting
  • Optioneering
  • Feasibility studies
