WATER REGULATION. Each boat that is attached to the Marina water system, directly or indirectly, shall be fitted with a water pressure regulation device. That device shall regulate the inlet water pressure entering the boat to a pressure not to exceed 40 P.S.I. (pounds per square inch).
WATER REGULATION. To cope with groundwater issues, during the 1980s, the state of Arizona established Active Management Areas (AMA) - Tucson Metropolitan Area is located in the Tucson AMA – which have specific regulations enforced by the state via the Arizona Department of Water Resources. The aim is to control water demand and reach the “safe-yield” (balance between withdrawal and replenishment into the aquifer) within the AMA limits which include the metropolitan, mining and 13 The City of Tucson. 1993.

Subsequently, another regulation obligated all new developers in the AMA to prove that 100 years of water supply is available in the area under construction.15 Figure 7. Xxxx Ranch housing development and water connections evolution (1984 and 2010) Many neighborhoods were built beyond the reach of existing water and sewer services. The builder therefore created a private water company to serve the development’s homeowners or financed the extension of the infrastructure (Xxxxx, 2006). The Xxxx Ranch development, in far southeast Tucson just north of the Town of Sahuarita, is a good example of this procedure. The area that now contains the Xxxx Ranch housing development had no water connections in 1984 and by 2010 had nearly 10,000 connections (Figure 7). 15 In the Tucson Region two kinds of water exist: wet water and paper water (water credits, assured water supply designations, water rights…). That separation can lead to hydrological contradictions like recharging the aquifer in one place to have the right to withdraw water in another. Another example would be Dove Mountain in Marana that went from 0 to almost 10,000 water/sewer connections by gaining water and wastewater services even though the development was many miles from the urban boundary (Figure 8; Clavreul et al., 2011).
