Hello,
I am trying to set up a Rainwater Harvesting system for my apartment complex. It has 14 floors with a garden on the 15th floor terrace and on the 16th floor, water tanks have been set up. The 15th floor area is approx 900 Sq mtrs and 16th floor is approx 800 Sq mtrs. Would like your advise on the following.
1. Should I harvest the 15th and 16th floor waters separately. 15th floor has a garden and people walk around frequently and there are some reservations for people to use this water for Bathroom, kitchen ( washing vessels only) and toilet needs
Or
2. Should I harvest the 15th floor waters for gardening and car was. How can we ensure the waters have less or no contamination from the fertilizers, pesticides and dust.
Or
3. The 16th floor waters could be used for Kitchen, bathroom and toilet needs only and could be directed into our existing sump with appropriate filters.
4. Lastly assuming there would be approx 17~20 Lakh litres of water that is harvested annually and about 1000 MM rainfwall for South Bangalore. What should be the brand and nature of filters to be used. It should be a heavy duty filters that can atleast filter between 30K~45K litres of water per hour
Tnanks for your help and guidance in this regard
