“…This list was used to identify four requests—two each in water and wastewater, with one each representing small and large communities. The authors specifically focused on the Lower Hudson region of the state, as it is the fastest‐growing region in the state, and its water and wastewater infrastructure has been the focus of recent study (Vedachalam et al 2014b, Rahm et al 2013, Vedachalam & Riha 2012). Table 1 summarizes the four municipalities' socio‐economic characteristics.…”

Many US municipalities confront serious challenges due to aging water and wastewater infrastructure. Many systems require immediate repairs, upgrades, and replacement, but available funding is scarce. Readily available low‐interest financing is of great help to such municipalities. The Water Infrastructure Finance and Innovation Act (WIFIA) approved by Congress in 2014 was a step in that direction. WIFIA is a five‐year pilot program focused on supporting large‐scale projects that may be under‐served by existing state revolving funds (SRFs). The authors examine the structure and implementation of WIFIA and its impact on existing financing mechanisms. The cost of debt service in four representative communities in New York was compared under WIFIA, SRFs, and tax‐exempt municipal bonds. Although WIFIA financing offered the lowest debt service cost, savings from WIFIA depended on the spread between US Treasury rates and borrowing rates of the SRF‐administering agency.

“…An integrated assessment of natural resources, social factors and economic factors at the watershed scale is required for sustainable management of watersheds and the communities they support (Curtis et al, 2005;Dhakate et al, 2013;Rahm et al, 2013). A conceptual framework for assessing the watershed dynamics is illustrated in Fig.…”

“…Different areas appropriate technologies choice (analyzed together in a multi-layer basin with different water bodies presenting different assimilation capacities) further elevates the difficulty level. Since downstream watercourse quality is affected by upstream conditions, wastewater treatment facilities cannot be considered isolated from each other (RAHM et al, 2013).…”

In order to determine required wastewater treatment plants (WWTP's) efficiencies, several methodologies have been proposed to assist the sewage treatment systems process selection, usually aiming to achieve economic objectives. However, in water resources problems solving, search involves multiple and conflicting objectives. This work used, for Pardo's river basin (Espírito Santo State, Brazil), water quality simulation model, optimization technique and multiobjective analysis for selecting sewage treatment systems, taking into account Brazilian environmental effluents Biochemical Oxygen Demand standards, imposed by CONAMA Resolution 430/2011. After proposing an optimization model that allowed the estimation of minimum organic matter removal efficiencies, a multiobjective analysis was applied by using the ELECTRE III method, which selected sewage treatment systems for localities responsible for domestic wastewater disposal in Pardo's river basin. The results indicated that keeping the effluents standards can produce treatment plants overestimation and inadequate allocated financial resources distribution for sewage treatment plants implementation. Treatment systems such as Submerged Aerated Biofilters (with Nitrification), Wetlands and Facultative Ponds were the most selected, considering different contexts appreciated in this work.
