Flood Risk and Drainage Impact Assessments

Flood risk assessment

Recent flooding events, and reports of more extreme weather to come go on to raise questions on the vulnerability of our homes and businesses. A lot of progress has been made in developing flood protection devices and retrofit solutions for existing properties but how can we ensure that buildings of the future do not suffer the same fate?

If you’re installing a renewable energy system, a Flood Risk Assessment (FRA) will help you to understand the risk of flooding close to your proposed site but the level and type of information available can make the process more complex than it needs to be.

Drainage Impact Assessment

Enviko are able to provide Drainage Impact Assessments as part of your planning application to accompany a Flood Risk Assessment or as a standalone document. This assessment provides clients with all the base data required to make an informed decision regarding the drainage strategy for the site of your prospective renewable system and any constraints likely to be applied by the governing bodies with regard to drainage of a site or development.

The Drainage Impact Assessment that Enviko offers can include:

  • 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
  • The preliminary design and viability of sustainable drainage techniques, including soakaways, swales, ponds, attenuation tanks, on line and off line piped storage
  • Calculation of existing Greenfield or Agricultural runoff rates
  • Mitigation measures for construction and detailed design should the development be in a groundwater source protection zone
  • Consultation service to sewerage undertaker to establish acceptable rates of discharge and points of outfall for both foul and surface water
  • Preliminary assessment of storm water attenuation requirements and volumes
  • Determination of foul and surface water runoff generated by new developments
Enviko has produced many Drainage Impact Assessments for all types of development including residential, commercial and retail developments of all sizes. We provide this service for sites throughout the UK.

wind Turbine Selection and Procurement

Turbine Selection and Procurement Turbine procurement is one of the most important aspects of a wind energy development. Turbines may represent up to 80% of the capital cost of a wind farm and their reliability and long-term power output are crucial to the financial performance of the project.

It is important to secure not only an acceptable price, but also the right guarantees, delivery and performance bonds and specific guarantees on aspects of performance governed by planning conditions, such as noise.

We have long-standing contacts with all the major manufacturers. Acting on behalf of owners, investors and banks, Enviko draws on years of experience to offer a comprehensive array of commercial and management services.

Whether planning, acquiring, operating, re-powering or selling a wind farm, Enviko can offer clients a range of skills and experience – from essential project services such as due diligence, through to adding value by way of project lifetime support.

Many farmers are wary of wind turbines due to fears of cost. On top of the rising prices of feed, fertiliser and utility bills, such extras are very off-putting. But there are green alternatives which can not only save you money but earn a second income... Read More.

Wind power for your commercial body is a great solution for alternative energy demands. Turbines provide a second income through feed-in-tariffs.... Read More.
