  3. The Davigulli has been designed by JDP through understanding the needs of both the installer and the local authority who maintain the system. Through the BBA accreditation JDP’s customers have commented on the Davigulli, proving its quality....”good product-many thousands used in the region” “used/specified for 10 years and on in excess of 1000 sites".
