3. Improvement Efficiency of Pumps in City Moat
Pumps in the city moat of Chiang Mai, there are the 66 pumps in process water fountain pumps around the city moat surrounding the old city. Known for tourism, the city is keen to have these fountain fully functional at all time.
Pumps are operating 10 hours a day. However, the pumps consume a lot of energy, break down
often, and put stress on both budget and manpower for operation and maintenance

Team staff investigated pumps efficiency at city moat and problems could be found such as heat, fountain’s clogging and pressure

Actual situation in Chiang Mai:Combined gravity storm- & waste-water collection system
Storm water drainage lines are used to drain:
• Effluent of the septic tanks
• Grey water (kitchens and bathrooms) > diluting effect
• Storm water (rainwater) > diluting effect > no energy recovery <
4. Wastewater Collection System in old town and whole-sale fresh market

Alternative waste water collection system: Vacuum sewer collection
Vacuum System: Cost effectives
• Small pipes (80-250mm)• Shallow, narrow trenches (0,6 - 1.2m)• Simple and fast• Simple or even no machinery required
(Energy saving potential)• No manholes, inspection pipes only• No lifting (pump-) stations required• Fresh water and waste water pipes in the same
trench allowed
According to EN it is permitted to install both potable water
pipes as well as vacuum sewer pipes within one single
trench.
According to EN potable water pipes must be installed in a
separate trench and higher level than the gravity sewer
pipes.
