<h4>In addition we will require the following;</h4>

<p>Two no. 1:500 (or larger) true-to-scale plans, showing the layout of the development including positions of all buildings, roads, plot numbers, utility strips / footpaths and widths. These must be free of colour, dark shading or any proposed service layouts. They should also include a scaling pole and have contours and spot-level layers removed. In addition, the drawings need to show existing infrastructure to enable us to accurately plot our existing mains. If these drawings are to be emailed, they should be compatible with Autocad 2010 or PDF and saved to scale at your end.</p>

<p>A plan marked up to indicate the extent of the highway to be adopted by the Local Authority.</p>

<p>A Soil Report</p>

<p>A plan of the drainage layout including details of any permeable drainage areas </p>

<p>For any non-domestic units, the peak flow and pressure demand.</p>

<p>Once these have been received we will be pleased to offer you terms for the mains extension.</p>

<p>Please note that Statement of Costs for new build properties on developments where a new main has been requisitioned will only be released once the newly laid main has been commissioned and any easements on the land completed.</p>

It will not, however, give any details regarding costs.
