The Municipal Water Supply and Sewerage Company of Larissa (DEYAL) is the first and largest Municipal Company in the field, after EYDAP and EYAT, with modern facilities and top quality services.
DEYAL is a Legal Person governed by Private Law, with a social utility character. It took its current legal form in 1981, by virtue of the P.D. 374/10-4-1981. Ever since, its operation and organization are governed by the provisions of L. 1069/80 "on incentives for the establishment of Water Supply and Sewerage Companies"; this law specifies the scope and duties of DEYAL, namely: the provision of Water Supply and Sewerage, as well as the study, construction, maintenance, exploitation, administration and operation of water supply networks, runoff and wastewater sewerage networks and sludge and wastewater treatment units (Biological Cleaning) in the area of DELYAL competence.
The scope and duties of DELYAL have expanded, in accordance with article 2, L. 1069/80 and by virtue of the no. 12635/16-8-2005 decision of the Secretary General of the Region of Thessaly, in the management, exploitation and trade of energy sources resulting from the activities of DELYAL and from the activities of the Municipality of Larissa.

The supplied water is received from the 17 bores (7 in Ampelonas, 5 in Yannouli and 5 in Platanoula), then is channeled to the reservoirs of Agia Paraskevi and Mezourlou and is distributed to the city thanks to the gravity created due to the height difference.
