Wastewater Management – Above Green

(possible 5 points)

Intent

To reduce pollution from wastewater, encourage water reuse and reduce stress on freshwater sources.

Requirements

Use treated wastewater to meet the city water demand. Calculate the percentage of treated wastewater used to meet the city water demand using the following equation.

Support treated wastewater reuse from decentralized plants, which is not within the scope of the development authority’s direct execution, such as at building or community level by adopting appropriate regulations, policies or ordinances. Cities should meet the requirements of WE Prerequisite: Water Access and Quality to meet the quality requirements of treated and discharged wastewater. Points are awarded as per the Table below.

Table 7. Percentage of wastewater reused to meet total water demand

Percentage of wastewater reused	Points
70% and above	5
50% to 69%	4
30% to 49%	3
10% to 29%	2

Wastewater management system should be planned and designed to cater to the phase-wise development of the city to ensure that the requirements are met at each phase.
