# Alternatively, one can also go for treating greywater only.
# Select the appropriate technology type depending on cost and land constraints.
Guide to use GRIHA online evaluation tool
Given below is a snapshot of the GRIHA Criterion 21 template for a project where the two points are
being attempted.
The following snapshots show samples of supporting documents that are required to be
submitted. The documents and drawings can be uploaded using the online tool.
Narrative
The packaged common sewage treatment plant of 50 m3/day capacity is proposed to treat the wastewater generated from different
buildings in the campus including the environmental sciences and engineering building. The amount of wastewater from this building is
equivalent to 8.5 m3/day. The treatment system is based on the INDION New Generation Packaged Sewage Treatment Plant (NGPSTP)
of Ion Exchange India Ltd. It is a unique combination of lamella plate clariication and aeration that results in a ready-to-operate, pre-
fabricated solution. The process includes primary settlement wherein the suspended solids are reduced to an extent of 75% through the
use of lamella parallel plates. There is also a reduction in BOD by 25%. The wastewater then enters the aerator bio-zone, which is a
combined ixed ilm reactor and active aeration system mounted on a horizontal shaft. The aerobic biodegradation of the organic matter
present in the wastewater occurs in this zone. The aerator provides a solid surface area for micro-organisms and the aeration is facilitated
by the rotation of the drum. The treated water then moves to the settlement area where the settlement of iner particles occurs through
the use of lamellar plate assembly. The sludge is removed at regular interval, which is then used as fertilizer.
Narrative
8.5 m3 of wastewater generated daily from the building will be treated in the common treatment plant for the campus. The treated water
will be reused for landscape irrigation and the sludge removed at regular intervals from the treatment plant will be used as fertilizer.
