Preliminary Drainage Design Services

Preliminary Drainage Design is required and recommended in Outline and some Detailed Planning Applications.

  • Assessment of existing drainage infrastructure to establish accurate current rates of surface water and foul run off from a site. (This is a critical service we provide as this rate of discharge forms the basis of the proposed drainage design and attenuation required on site)
  • Assessing capacity and suitability of existing drainage systems to accommodate additional flows
  • Calculation of existing Greenfield or Agricultural run off rates
  • Preliminary assessment of storm water attenuation requirements and volumes
  • Determination of foul and surface water run off generated by new developments
  • Consultation service to sewerage undertaker to establish acceptable rates of discharge and points of outfall for both foul and surface water
  • The preliminary design and viability of sustainable drainage techniques, including soakaways, swales, ponds, attenuation tanks, on line and off line piped storage
