QuestionView source ↗

I refer to the application by J.B. Mathews for a ground water area well licence for 5.84 gigalitres of water to irrigate 324.4 hectares of vegetables, principally potatoes and carrots, in the Gingin ground water area. (1) Can the minister confirm whether the applicant has already commenced vegetable production, including use of the water, prior to the licence application being considered; and, if so, how much water has been used? (2) If yes, what action will be taken against the applicant? (3) Have vegetation studies and hydrogeological reports been submitted by the applicant to the Water and Rivers Commission prior to any land being cleared, production undertaken and water being used? (4) How many bores have been put down for this property and are there plans to increase the number of bores? (5) In view of the need for water conservation strategies, does the minister believe that 5.84 gigalitres of water is an excessive amount, and will any monitoring to detect water logging or salt water intrusions into the ground water be carried out at the applicant’s expense? Hon TOM STEPHENS

The minister has provided the following response - (1) There has been no unauthorised water use to the knowledge of the Water and Rivers Commission. The commission issued a licence for a stage 1 development on 18 June 2002. This licence provides for the irrigation of 162 hectares of vegetables with an allocation of 2.916 gigalitres. The total development amounts to 486 hectares requiring an allocation of 8.7 gigalitres. The applicant is in the process of installing the infrastructure for the commencement of growing vegetables. (2) Not applicable. (3) Yes. Hydrogeological reports were submitted to and assessed by the Water and Rivers Commission. Advice to the commission from the Department of Agriculture stated that notification of cleared land was not necessary as the area had been regularly cropped and pastured in the past. (4) Two production bores have been installed for stage 1, and one is under construction. A total of 18 bores is proposed. (5) No. The current modelling results indicate that the proposed abstraction of 8.7 gigalitres is sustainable. Licence conditions require the installation of monitoring bores at appropriate locations. These will be installed and monitored regularly for water level and quality by the developer. It is not anticipated that water logging will be an issue as the water table is between 60 and 125 metres below ground level. Salt water intrusion is not considered an issue as the development is more than seven kilometres from the coastline.
