Green & Sustainable Features: Solar Power, Rainwater Harvesting, and Water Recycling

Green Engineering Is Smart Economics

Historically, eco-friendly features were treated as luxury embellishments. Today, with rising municipal water tariffs and escalating electricity rates in urban Visakhapatnam, sustainable architecture is the single most effective way to keep your society's recurring monthly maintenance affordable.

1. Rooftop Solar Photovoltaic (PV) Net Metering

In an average 20-flat apartment complex, running elevators, borewell motors, sump pumps, and overnight security lighting consumes 1,500 to 2,500 units of electricity each month.

By installing a 10 kW grid-tied solar system on the terrace:

• The building generates approximately 1,200 to 1,400 clean units per month.
• Under APEPDCL's net-metering policy, the generated units are subtracted directly from the common meter bill.
• The society saves ₹12,000 to ₹18,000 every single month, protecting residents against future tariff hikes for the 25-year lifespan of the solar panels.

2. Rainwater Harvesting & Groundwater Recharge

Vizag receives an average annual rainfall of approximately 1,000 mm. A 600 square-yard building terrace catches nearly 5,00,000 liters of pure rainwater every monsoon.

Instead of allowing this clean water to overflow into roadside storm drains:

1. First-flush diverters isolate initial rooftop dust.
2. The water passes through a multi-tier filtration chamber (graded gravel, charcoal, and river sand).
3. The purified water recharges the local deep borewell aquifer, ensuring your building's freshwater supply remains sweet and plentiful even during the dry summer months of May and June.
