Commisioning of the filter is achieved by filling water, initially from thebottom up,until the level rises just above the sond thus allowing final inletflow without scour and preventing air entrapment.

3. Maturation period takes 2 ' 3 weeks, before the newly commisioned filterbecomes effective in purifying the water » during which time the filter isoperated at '/4 the design rate ond filtrant run to waste. Filter is placedinto full operation once the schmutzdecke , a reddish brown sticky coating,has formed on the sand surface-

4. Once the required filtration rate con no longer be maintained, due tohigh resistance to flow of the filter medium, cleaning of the sand isnecessary. The frequency of cleaning will vary from 2 0 - 4 0 days, (less witnterrom fabric m ptace- see G.A. detail) depending on quality of raw water

5. Cleaning procedure :•• Drain supernatant to about (00mm below sond level and remove terrom• The top 25 - 0 mm of sand is scraped ond removed, observing all

necessary levels of hygiene and eiposing the sond for the minimumof time. The terram fabric, once cleaned, is ptoced bock the top of the sand

• The filter is refilled with water ( see note 2 )• Filtration ra te , initially at l /4 design rate with filtrant run to

waste, is brought up to full design rote over 12 hours, ond filteredwater placed into supply after 24 hours.

6 The scraped sand should be thoroughly cleaned, (see cleaning baydetail) , and protected ogainst dust and pollution by adequately storing

7. Resondtng (see detoil) is required once the sond level reaches aminimum depth of 6 5 0 mm , after successive scrapings. After re sandingthe filter will take o minimum of one week to reach full maturation

DOs and DONT s for VIP vent pipei-

00 _ Put the vent outside the superstructureDO _ Put it facing the sunDO — Make it 100 mm dia or largerDO — Make it as high os possible (See inset clearance detail)DO — Place it directly over the pitDO _ Cover it with stainless steel gauze

DONT _ Put it inside (It gets in the way of the pan)DON'T _ Have holes or cracks in it (Fhes can escape)DONT _ Cut it short (Air will not flow)DONT _ Cover the vent (tt excludes light and stops air flow)DONT _ Have a superstructure without a roof (Fhes will not be

at t racted to the vent)

It has been observed that the success of a latrine programme is asmuch dependent on good technology as it is on o good delivery systemWell designed and made latrines will NOT work satisfactorily UNLESSthey ore introduced to communities in o way that makes them want touse them properly. Thus this drawing should be read together with theManual tor low cost rural water supplies and sanitation* UNICEF , Quetta,1986

Dimension is determined according to soil type and founding requirements,as per site conditions and the decision of the Engineer-tn-cnorge
