4-Nov-14 1 Water supply lines are to be installed as shown in Site Utilities Plan (SN

— 001). However, control valves are only shown at entrance to blocks.

Do we need valves elsewhere as well?. There is also no water supply line shown to be installed for Pit Latrine. Please clarify.

1. Water supply control valves shall be at entrance to blocks.

2. Pit latrine will get water supply. The cost will be covered by omitting the water line loop between Registration and OPD Blocks and using credit to supply to Pit latrine. See attached revised Sheet SN-001.

1. Concerning control valves please proceed as per the drawings.

2. Concerning pit latrine water supply please refer to SN-010 for installation detail.
