City and Gawler. Parafield Airport, Adelaide's main civil airport from 1927 to 1955, lies just to the north of Mawson Lakes and is currently used for small aircraft, pilot training and recreational aviation. Water supply Mawson Lakes features a dual water supply system, supplying drinking water and recycled water to homes via completely separate mains. When first installed the facilities at Mawson Lakes were the largest self-contained water recycling scheme in Australia. Purple pipes and fittings are used to distinguish recycled water sources. The recycling scheme results in Mawson Lakes using 50% less potable water than comparable suburbs and means that resident using recycled water are exempt from state water restrictions The recycled water is sourced from the Bolivar Sewage Treatment plant approximately 8 km away and then has stormwater added to it from the Salisbury wetlands before it is treated to Class A standard recycled water for use on gardens, reserves and connected to the toilet of each residence in Mawson Lakes. SA Water provides a comprehensive audit of homes within the area to ensure that cross connection between the recycled water and drinking water does not occur. Mawson Central The central commercial area of Mawson Lakes, situated between Main Street and Garden Terrace, and north of the Promenade is the central shopping precinct with a Hotel, Woolworths, ALDI, and a number of smaller shops and restaurants. Main Street and its side roads are also home to Bank branches, various professional services, and a number of offices. In recent years, many offices have been converted into apartments due to the proximity of the university and a glut of office space.
