Repeat Problem 12-2 assuming the following water saving features are introduced:

a. Low-flush toilets that reduce flow from 73 to 35 L/capita · d.

b. Limiting flow shower head that reduces flow from 50 to 42 L/capita · d.

Problem 12-2

A proposal to build Hotel California is being evaluated to estimate wastewater flow rates. Two proposals are being considered. Estimate the average and peak hour wastewater flow rate for each proposal. State all assumptions. The owner has asked two questions:

(1) What is the impact on wastewater flow rate of having a bar with the restaurant?

(2) With respect to wastewater flow, are there any economies of scale?

The proposals are outlined in the table below. Assume an average occupancy of 80%, 1.5 people per room, and a maximum occupancy of 100%, 2 people per room.
