This follows a series of meetings between the two sectors after the implementation of Temporary Use Bans by seven water companies in April this year.
The project aims to provide a training model on water efficiency that is suited to the landscape and sports sectors. The project will be managed by Waterwise, the independent water efficiency organisation.
The trade bodies which include the Association of Professional Landscapers, British Association of Landscape Industries, Horticultural Trades Association, Society of Garden Designers and Turf Growers Association, will incorporate the end product into their relevant audit processes and membership criteria.
Learners will receive a Waterwise Best Practice Certificate.
HTA policy manager Gary Scroby said: "By embedding best practice in water use, landscape professionals can demonstrate a responsible approach on water efficiency and resilience. We hope the e-learning will help spread this important message; by successfully qualifying for the Best Practice Certificate and demonstrating reductions in use through water efficient practice, learners should have a stronger business case for an exemption from any future hosepipe bans."
The water companies that have agreed to support the initiative include Affinity Water, Anglian Water, South East Water, Southern Water and Thames Water.
