Minimum cover over pipes is 0.6 meters or sufficient to support imposed dead and live loads for the pipe materials used, whichever is more stringent. Place plastic warning tape along the route of the buried pipe after installation at a height of 0.3 meters above the pipe.

2.11.1 STORM SYSTEM

The Contractor shall provide the most appropriate drainage system for the site, in accordance with host nation and local government regulations. The Contractor will take into account the information gathered from the site survey, local climate and rainfall data, 10 year return storm frequency, and any geotechnical/hydrological investigation.

Provide drainage ditches, swales, or other gravity-driven drainage features to divert surface runoff away from structures. Design drainage features to eliminate ponding and to be protected against erosion. Provide 2 meters of gravel erosion protection around the perimeter of the proposed school building.

The Contractor shall take special care to avoid poor site drainage, stagnant water, and ponding anywhere on the project site in order to minimize the likelihood of water-borne diseases, which are prominent in this region.

Connect building roof gutters and downspouts to a rainwater tank (5000 liter). Locate tank out of pathways and windows. Provide a spigot at the bottom of each rainwater tank. Below the spigot, provide a splash block that will drain water away from building foundation a minimum of 3 meters per site grading requirements. Provide an overflow system from the tank to splash blocks that drain away from foundation a minimum of 3 meters per site grading requirements. Provide insect screens to all open orifices to the tank system. Provide UV resistant tanks. Provide concrete foundation to support rainwater collection tank, and install the bottom of the tank a minimum of 60 centimeters above finish grade. Provide structural tie downs for the tank. Provide an opening for cleaning and allow access into the tank. Provide system in order to divert first flush from the roofs that may be contaminated with dust, animal droppings and dirt so that it does enter the tank. Provide sign next to tap that shows a pictogram “not for drinking”. Sign must be firmly fastened aluminum or other durable weather resistive material (no adhesive sticker allowed).

2.11.2 SANITARY SYSTEM

The project utilizes VIP latrine cabin sanitary septic system as discussed in SOW Section 3.0 – ARCHITECTURE. If the Geotechnical Investigation determines that groundwater is less than 1 meter deep, raise the latrine per WHO Fact Sheet 3.5. In the absence of Host Nation standards, design the latrine disposal system per WHO Fact Sheet 3.5.

2.12 LANDSCAPING

Existing trees within the site construction areas that are to remain in place shall be properly protected during construction work. Any trees or shrubs that are to remain in place and are damaged by the Contractor shall be, irrespective of the degree of damage, replaced in kind and number.

The Contractor shall provide a landscaping plan showing, at a minimum, the exact existing landscaping to be removed and the location and limits of areas to be restored and/or repaired which were damaged by contractor’s work effort, if any. Restoration plan will include, at a minimum, a plan for re-establishment of ground cover consistent with the surrounding area. These items shall be indicated on the new site plan.
