Biome Environmental Solutions

This presentation by Biome Environmental Solutions Private Limited introduces a plan for Rainwater Harvesting (RWH) for the city of Bangalore. The objectives of the plan include:

These two documents enlist best practices in urban water management, based on the experiences of Biome Solutions, and are relevant for households in a gated layout/group housing complex, where the water sourcing, supply and management is in the hands of the layout and there is no connection to the the local water supply authority.

Based on the annual costs of imported (purchased) water, pumping (energy), water supply infrastructure and borewell maintenance, wastewater treatment, human resources, rainwater harvesting maintenance, sinking fund (cost of replacement of infrastructure), this spreadsheet-based toolkit by Biome Solutions, helps calculate the total cost (in Rs/KL) of water.

Based on user-entered data on domestic water demand, waste water discharge, rainfall availability and recharge, extent of reuse of treated waste water, this spreadsheet-based toolkit developed by Biome Solutions allows you to juggle around with the relevant data fields, and figure out various ways in which you can bring down your overall groundwater draft (and hence ecological footprint) as low as possible, and gives a snapshot result of your overall household-level water input and output situation.

 Biome Solutions, a Bangalore-based company working on sustainable architecture and buildings visited some flood affected areas in Guntur to observe the situation and see the suitability of applying "Ecological Sanitation", a new approach to sanitation. (Search on India Water Portal for "Ecological sanitation" for more information on this). Their report  after their travels can be seen below.

A point of interest is the picture of a flooded toilet. Pit toilets which are the norm in rural areas have the disadvantage that during floods the pit below the toilet (where the human waste accumulates over time) gets flooded and the toilet becomes unusable. The faecal matter can come out of the toilet pan and create a real mess which needs to be cleaned up.

Bangalore's sprawling expansion outpaces the public utility's ability to accommodate skyrocketing demand for water and sanitation services, and it is increasingly common for new residential communities to assume total management for their own water and sanitation services through their resident welfare associations.
