1. Title Block:

  • Development name;
  • Developer details;
  • Agent details;
  • Drawing number (including revision);
  • Revision block inclusive of dates;
  • Revision marks;
  • Scale bar(s).

2. In addition all Subdivision Layout Sheets will include:

Appendix C — Requirements for Design Submission 1 (Master Plan)

Water supply

If the parcel of land is divided by a water supply pressure zone boundary, as much as possible of the parcel must be served from the lower zone. Icon Water reserves the right to determine the actual location of the zone boundary, which may involve alteration of the Developer's Water Supply Master Plan.

Generally, all water mains that are to be handed over to Icon Water as town mains are required to be laid within the public road reservations in accordance with the alignments shown on Road Verge Drawings — Drawing Nos. SEP4 — 01 to 06, Chapter 4 (Road Verges) (Reference 5.2), or their replacements.

In special circumstances, easements or reservations may be required for water mains not located in public roads. The dimensions of these easements must be ascertained from Icon Water, and must be clearly marked on the Master Plan and eventually on Land Act lease plans. Generally, mains in private roads, private accesses, or private car parks are not classified as town mains. Town water mains larger than DN150 are not permitted in leased blocks.

The Water Supply Master Plan to be submitted for approval should contain the following:

  • Road and block layout at a scale of 1:2500 on either Al or Bl sheet size;
  • Block and section numbers, if available;
  • Street names, if available;
  • Contours at 2.0 metre intervals;
  • Grid co-ordinates and North Point oriented up the sheet;
  • Land use other than standard detached housing (refer to Water Supply and Sewerage Standards — Part 2, Table 2-1);
  • Proposed water mains with sizes and positions of all valves and hydrants;
  • Fire risk categories where other than F6 (refer to Water Supply and Sewerage Standards — Part 2, Clause 3.3 and Table 2-2);
  • Zone boundaries, if any;
  • Existing mains feeding the area;
  • Existing easements, if any.
